- GCC 3.0
-
- TBA
-
- The [1]GNU project and the GCC developers are pleased to announce the
- release of GCC version 3.0.
-
- GCC used to stand for the GNU C Compiler, but since the compiler
- supports several other languages aside from C, it now stands for the
- GNU Compiler Collection.
-
- GCC 3.0 has several new optimizations, new targets, new languages and
- many other new features. See the [2]new features page for a more
- complete list.
-
- The GCC developers would like to thank the numerous people that have
- contributed new features, test results, bugfixes, etc to GCC. This
- [3]amazing group of volunteers is what makes GCC successful.
-
- And finally, we can't in good conscience fail to mention some
- [4]caveats to using GCC 3.0.
-
- For additional information about GCC please refer to the [5]GCC
- project web site or contact the [6]GCC development mailing list.

-
- GCC 3.0 New Features
-
- * General Optimizer Improvements:
- + [1]Basic block reordering pass.
- + New if-conversion pass with support for conditional
- (predicated) execution.
- + New tail call and sibling call elimination optimizations.
- + New register renaming pass.
- + New (experimental) [2]static single assignment (SSA)
- representation support.
- + New dead-code elimination pass implemented using the SSA
- representation.
- + [3]Global null pointer test elimination.
- + [4]Global code hoisting/unification.
- + More builtins and optimizations for stdio.h, string.h and old
- BSD functions, as well as for ISO C99 functions.
- + New builtin __builtin_expect for giving hints to the branch
- predictor.
- * New Languages and Language specific improvements:
- + The GNU Compiler for the Java(TM) language (GCJ) is now
- integrated and supported, including the run-time library
- containing most common non-GUI Java classes, a bytecode
- interpreter, and the Boehm conservative garbage collector.
- Many bugs have been fixed. GCJ can compile Java source or
- Java bytecodes to either native code or Java class files, and
- supports native methods written in either the standard JNI or
- the more efficient and convenient CNI.
- + New C++ ABI, capable of inter-operating with other IA-64
- compilers.
- + The new ABI also significantly reduces the size of symbol and
- debug information.
- + New C++ support library and many C++ bug fixes, vastly
- improving our conformance to the ISO C++ standard.
- + New [5]inliner for C++.
- + Rewritten C preprocessor, integrated into the C, C++ and
- Objective C compilers, with very many improvements including
- ISO C99 support and [6]improvements to dependency generation.
- + Support for more [7]ISO C99 features.
- + Many improvements to support for checking calls to format
- functions such as printf and scanf, including support for ISO
- C99 format features, extensions from the Single Unix
- Specification and GNU libc 2.2, checking of strfmon formats
- and features to assist in auditing for format string security
- bugs.
- + New warnings for C code that may have undefined semantics
- because of violations of sequence point rules in the C
- standard (such as a = a++;, a[n] = b[n++]; and a[i++] = i;),
- included in -Wall.
- + Additional warning option -Wfloat-equal.
- + Improvements to -Wtraditional.
- + Fortran improvements are listed in [8]the Fortran
- documentation.
- * New Targets and Target Specific Improvements:
- + New x86 back-end, generating much improved code.
- + Support for a generic i386-elf target contributed.
- + New option to emit x86 assembly code using Intel style syntax
- (-mintel-syntax).
- + HPUX 11 support contributed.
- + Improved PowerPC code generation, including scheduled
- prologue and epilogue.
- + Port of gcc to Intel's IA-64 processor contributed.
- + Port of gcc to Motorola's MCore 210 and 340 contributed.
- + New unified back-end for Arm, Thumb and StrongArm
- contributed.
- + Port of gcc to Intel's XScale processor contributed.
- + Port of gcc to Atmel's AVR microcontrollers contributed.
- + Port of gcc to Mitsubishi's D30V processor contributed.
- + Port of gcc to Matsushita's AM33 processor (a member of the
- MN10300 processor family) contributed.
- + Port of gcc to Fujitsu's FR30 processor contributed.
- + Port of gcc to Motorola's 68HC11 and 68HC12 processors
- contributed.
- + Port of gcc to Sun's picoJava processor core contributed.
- * Documentation improvements:
- + Substantially rewritten and improved C preprocessor manual.
- + Many improvements to other documentation.
- + Manpages for gcc, cpp and gcov are now generated
- automatically from the master Texinfo manual, eliminating the
- problem of manpages being out of date. (The generated
- manpages are only extracts from the full manual, which is
- provided in Texinfo form, from which info, HTML, other
- formats and a printed manual can be generated.)
- + Generated info files are included in the release tarballs
- alongside their Texinfo sources, avoiding problems on some
- platforms with building makeinfo as part of the GCC
- distribution.
- * Other significant improvements:
- + Garbage collection used internally by the compiler for most
- memory allocation instead of obstacks.
- + Lengauer and Tarjan algorithm used for computing dominators
- in the CFG. This algorithm can be significantly faster and
- more space efficient than our older algorithm.
- + gccbug script provided to assist in submitting bug reports to
- the GCC GNATS bug tracking database. (Bug reports previously
- submitted directly to the GCC mailing lists, for which no
- GNATS bug tracking number has been received, should be
- submitted again to the bug tracking database using gccbug if
- you can reproduce the problem with GCC 3.0.)
- + The internal libgcc library is [9]built as a shared library
- on systems that support it.
- + Extensive testsuite included with GCC, with many new tests.
- In addition to tests for GCC bugs that have been fixed, many
- tests have been added for language features, compiler
- warnings and builtin functions.
- + Additional language-independent warning options -Wpacked,
- -Wpadded, -Wunreachable-code and -Wdisabled-optimization.
- + Target-independent options -falign-functions, -falign-loops
- and -falign-jumps.
- * Plus a great many bugfixes and almost all the [10]features found
- in GCC 2.95.

-
- GCC 3.0 Caveats
-
- * Enumerations are now properly promoted to int in function
- parameters and function returns. Normally this change is not
- visible, but when using -fshort-enums this is an ABI change.
- * The undocumented extension that allowed C programs to have a label
- at the end of a compound statement has been deprecated and may be
- removed in a future version. Programs that now generate a warning
- about this may be fixed by adding a null statement (a single
- semicolon) after the label.
- * The poorly documented extension that allowed string constants in
- C, C++ and Objective C to contain unescaped newlines has been
- deprecated and may be removed in a future version. Programs using
- this extension may be fixed in several ways: the bare newline may
- be replaced by \n, or preceded by \n\, or string concatenation may
- be used with the bare newline preceded by \n" and " placed at the
- start of the next line.
- * The Chill compiler is not included in GCC 3.0, because of the lack
- of a volunteer to convert it to use garbage collection.

-
- GCC 2.95.2
-
- October 27, 1999
-
- The GNU project and the GCC developers are pleased to announce the
- release of GCC version 2.95.2. GCC used to stand for the GNU C
- Compiler, but since the compiler supports several other languages
- aside from C, it now stands for the GNU Compiler Collection.
-
- This is a minor release to address several bugs in the GCC version
- 2.95.1 release.
-
- The -fstrict-aliasing is not enabled by default for GCC 2.95.2. While
- the optimizations performed by -fstrict-aliasing are valid according
- to the C and C++ standards, the optimization have caused some
- problems, particularly with old non-conforming code.
-
- The GCC developers are experimenting with ways to warn users about
- code which violates the C/C++ standards, but those warnings are not
- ready for widespread use at this time. Rather than wait for those
- warnings the GCC developers have chosen to disable -fstrict-aliasing
- by default for the GCC 2.95.2 release.
-
- We strongly encourage developers to find and fix code which violates
- the C/C++ standards as -fstrict-aliasing may be enabled by default in
- future releases. Use the option -fstrict-aliasing to re-enable these
- optimizations.
-
- * Generic bugfixes and improvements
- + Fix incorrectly optimized memory reference in global common
- subexpression elimination (GCSE) optimization pass.
- + Fix code generation bug in regmove.c in which it could
- incorrectly change a "const" value.
- + Fix bug in optimization of conditionals involving volatile
- memory references.
- + Avoid over-allocation of stack space for some procedures.
- + Fixed bug in the compiler which caused incorrect optimization
- of an obscure series of bit manipulations, shifts and
- arithmetic.
- + Fixed register allocator bug which caused teTeX to be
- mis-compiled on Sparc targets.
- + Avoid incorrect optimization of degenerate case statements
- for certain targets such as the ARM.
- + Fix out of range memory reference in the jump optimizer.
- + Avoid dereferencing null pointer in fix-header.
- + Fix test for GCC specific features so that it is possible to
- bootstrap with gcc-2.6.2 and older versions of GCC.
- + Fix typo in scheduler which could potentially cause out of
- range memory accesses.
- + Avoid incorrect loop reversal which caused incorrect code for
- certain loops on PowerPC targets.
- + Avoid incorrect optimization of switch statements on certain
- targets (for example the ARM).
- * Platform specific bugfixes and improvements
- + Work around bug in Sun V5.0 compilers which caused bootstrap
- comparison failures on Sparc targets.
- + Fix Sparc backend bug which caused aborts in final.c.
- + Fix sparc-hal-solaris2* configuration fragments.
- + Fix bug in sparc block profiling.
- + Fix obscure code generation bug for the PARISC targets.
- + Define __STDC_EXT__ for HPUX configurations.
- + Various POWERPC64 code generation bugfixes.
- + Fix abort for PPC targets using ELF (ex GNU/Linux).
- + Fix collect2 problems for AIX targets.
- + Correct handling of .file directive for PPC targets.
- + Fix bug in fix_trunc x86 patterns.
- + Fix x86 port to correctly pop the FP stack for functions that
- return structures in memory.
- + Fix minor bug in strlen x86 pattern.
- + Use stabs debugging instead of dwarf1 for x86-solaris
- targets.
- + Fix template repository code to handle leading underscore in
- mangled names.
- + Fix weak/weak alias support for OpenBSD.
- + GNU/Linux for the ARM has C++ compatible include files.
- * Language & Runtime specific fixes.
- + Fix handling of constructor attribute in the C front-end
- which caused problems building the Chill runtime library on
- some targets.
- + Fix minor problem merging type qualifiers in the C front-end.
- + Fix aliasing bug for pointers and references (C/C++).
- + Fix incorrect "non-constant initializer bug" when
- -traditional or -fwritable-strings is enabled.
- + Fix build error for Chill front-end on SunOS.
- + Do not complain about duplicate instantiations when using
- -frepo (C++)
- + Fix array bounds handling in C++ front-end which caused
- problems with dwarf debugging information in some
- circumstances.
- + Fix minor namespace problem.
- + Fix problem linking java programs.
-
- The whole suite has been extensively [1]regression tested and
- [2]package tested. It should be reliable and suitable for widespread
- use.
-
- The GCC 2.95 release has several new optimizations, new targets, new
- languages and other new features as compared to EGCS 1.1 or GCC 2.8.
- See the [3]new features page for a more complete list of new features
- found in the GCC 2.95 releases.

- GCC 2.95
-
- July 31, 1999
-
- The GNU project and the GCC/EGCS developers are pleased to announce
- the release of GCC version 2.95. GCC used to stand for the GNU C
- Compiler, but since the compiler supports several other languages
- aside from C, it now stands for the GNU Compiler Collection.
-
- This is the first release of GCC since the April 1999 GCC/EGCS
- reunification and includes nearly a year's worth of new development
- and bugfixes.
-
- The whole suite has been extensively [1]regression tested and
- [2]package tested. It should be reliable and suitable for widespread
- use.
-
- The compiler has several new optimizations, new targets, new languages
- and other new features. See the [3]new features page for a more
- complete list of new features found in the GCC 2.95 releases.
-
- The sources include installation instructions in both HTML and
- plaintext forms in the install directory in the distribution. However,
- the most up to date [4]installation instructions and [5]build/test
- status are on the web pages. We will update those pages as new
- information becomes available.
-
- The GCC developers would like to thank the numerous people that have
- contributed new features, test results, bugfixes, etc to GCC. This
- [6]amazing group of volunteers is what makes GCC successful.
-
- And finally, we can't in good conscience fail to mention some
- [7]caveats to using GCC 2.95.

-http://gcc.gnu.org/gcc-2.95/caveats.html
-
- GCC 2.95 Caveats
-
- * GCC 2.95 will issue an error for invalid asm statements that had
- been silently accepted by earlier versions of the compiler. This
- is particularly noticeable when compiling older versions of the
- Linux kernel (2.0.xx). Please refer to the [1]FAQ for more
- information on this issue.
- * GCC 2.95 implements type based alias analysis to disambiguate
- memory references. Some programs, particularly the Linux kernel
- violate ANSI/ISO aliasing rules and therefore may not operate
- correctly when compiled with GCC 2.95. Please refer to the [2]FAQ
- for more information on this issue.
- * GCC 2.95 has a known bug in its handling of complex variables for
- 64bit targets. Instead of silently generating incorrect code, GCC
- 2.95 will issue a fatal error for situations it can not handle.
- This primarily affects the Fortran community as Fortran makes more
- use of complex variables than C or C++.
- * GCC 2.95 has an integrated libstdc++, but does not have an
- integrated libg++. Furthermore old libg++ releases will not work
- with GCC 2.95. You can retrieve a recent copy of libg++ from the
- [3]GCC ftp server.
- Note most C++ programs only need libstdc++.
- * Exception handling may not work with shared libraries,
- particularly on alphas, hppas, rs6000/powerpc and mips based
- platforms. Exception handling is known to work on x86 GNU/Linux
- platforms with shared libraries.
- * In general, GCC 2.95 is more rigorous about rejecting invalid C++
- code or deprecated C++ constructs than G++ 2.7, G++ 2.8, EGCS 1.0,
- or EGCS 1.1. As a result it may be necessary to fix C++ code
- before it will compile with GCC 2.95.
- * G++ is also converting toward the ISO C++ standard; as a result
- code which was previously valid (and thus accepted by other
- compilers and older versions of g++) may no longer be accepted.
- The flag -fpermissive may allow some non-conforming code to
- compile with GCC 2.95.
- * GCC 2.95 compiled C++ code is not binary compatible with EGCS
- 1.1.x, EGCS 1.0.x or GCC 2.8.x.
- * GCC 2.95 does not have changes from the GCC 2.8 tree that were
- made between Sept 30, 1998 and April 30, 1999 (the official end of
- the GCC 2.8 project). Future GCC releases will include all the
- changes from the defunct GCC 2.8 sources.

- on some platforms.
- + Avoid linking in EH routines from libgcc if they are not
- needed.
- + Avoid obscure bug in aliasing code.

- + Abort instead of generating incorrect code for PPro/PII
- floating point conditional moves.
- + Avoid multiply defined symbols on Linux/GNU systems using
- libc-5.4.xx.
- + Fix abort in alpha compiler.
-
- Fortran-specific fixes
- * Fix the IDate intrinsic (VXT) (in libg2c) so the returned year is
- in the documented, non-Y2K-compliant range of 0-99, instead of
- being returned as 100 in the year 2000.
- * Fix the `Date_and_Time' intrinsic (in libg2c) to return the
- milliseconds value properly in Values(8).
- * Fix the `LStat' intrinsic (in libg2c) to return device-ID
- information properly in SArray(7).
-
- An important goal of EGCS is to allow wide scale testing of new
- features and optimizations which are still under development. However,
- EGCS has been carefully tested and should be comparable in quality to
- most gcc releases.
-
- EGCS 1.1.2 is based on the June 6, 1998 snapshot of the GCC 2.8
- development sources; it contains all of the new features found in GCC
- 2.8.1 as well as all new development from gcc2 up to June 6, 1998.
-
- See the [1]new features page for a more complete list of new features
- found in EGCS 1.1 releases.
-
- The EGCS 1.1.2 release includes installation instructions in both HTML
- and plaintext forms (see the INSTALL directory in the toplevel
- directory of the EGCS 1.1.2 distribution). However, we also keep the
- most up to date [2]installation instructions and [3]build/test status
- on our web page. We will update those pages as new information becomes
- available.
-
- The EGCS project would like to thank the numerous people that have
- contributed new features, test results, bugfixes, etc. This [4]amazing
- group of volunteers is what makes EGCS successful.
-
- And finally, we can't in good conscience fail to mention some
- [5]caveats to using EGCS 1.1.2. [6]Download EGCS 1.1.2 from

- EGCS 1.1 is based on an June 6, 1998 snapshot of the GCC 2.8
- development sources; it contains all of the new features found in GCC
- 2.8.1 as well as all new development from GCC up to June 6, 1998.
-
- EGCS also contains many improvements and features not found in GCC or
- in older versions of EGCS.
- * Global common subexpression elimination and global constant/copy
- propagation (aka [2]gcse)
- * Ongoing improvements to the [3]alias analysis support to allow for
- better optimizations throughout the compiler.
- * Vastly improved [4]C++ compiler and integrated C++ runtime
- libraries.
- * Fixes for the /tmp symlink race security problems.
- * New targets including mips16, arm-thumb and 64 bit PowerPC.
- * Improvements to GNU Fortran (g77) compiler and runtime library
- made since [5]g77 version 0.5.23.
-

- found in EGCS 1.1 releases.
-
- The EGCS 1.1 release includes installation instructions in both HTML
- and plaintext forms (see the INSTALL directory in the toplevel
- directory of the EGCS 1.1 distribution). However, we also keep the
- most up to date [7]installation instructions and [8]build/test status
- on our web page. We will update those pages as new information becomes
- available.
-
- The EGCS project would like to thank the numerous people that have
- contributed new features, test results, bugfixes, etc. This [9]amazing

-
- EGCS 1.1 new features
-
- * Integrated GNU Fortran (g77) compiler and runtime library with
- improvements, based on [1]g77 version 0.5.23.
- * Vast improvements in the C++ compiler; so many they have [2]page
- of their own!
- * Compiler implements [3]global common subexpression elimination and
- global copy/constant propagation.
- * More major improvements in the [4]alias analysis code.
- * More major improvements in the exception handling code to improve
- performance, lower static overhead and provide the infrastructure
- for future improvements.
- * The infamous /tmp symlink race security problems have been fixed.
- * The regmove optimization pass has been nearly completely rewritten
- to improve performance of generated code.
- * The compiler now recomputes register usage information before
- local register allocation. By providing more accurate information
- to the priority based allocator, we get better register
- allocation.
- * The register reloading phase of the compiler optimizes spill code
- much better than in previous releases.
- * Some bad interactions between the register allocator and
- instruction scheduler have been fixed, resulting in much better
- code for certain programs. Additionally, we have tuned the
- scheduler in various ways to improve performance of generated code
- for some architectures.
- * The compiler's branch shortening algorithms have been
- significantly improved to work better on targets which align jump
- targets.
- * The compiler now supports -Os to prefer optimizing for code space
- over optimizing for code speed.
- * The compiler will now totally eliminate library calls which
- compute constant values. This primarily helps targets with no
- integer div/mul support and targets without floating point
- support.
- * The compiler now supports an extensive "--help" option.
- * cpplib has been greatly improved and may be suitable for limited
- use.
- * Memory footprint for the compiler has been significantly reduced
- for some pathological cases.
- * The time to build EGCS has been improved for certain targets
- (particularly the alpha and mips platforms).
- * Many infrastructure improvements throughout the compiler, plus the
- usual mountain of bugfixes and minor improvements.
- * Target dependent improvements:
- + SPARC port now includes V8 plus and V9 support as well as
- performance tuning for Ultra class machines. The SPARC port
- now uses the Haifa scheduler.
- + Alpha port has been tuned for the EV6 processor and has an
- optimized expansion of memcpy/bzero. The Alpha port now uses
- the Haifa scheduler.
- + RS6000/PowerPC: EGCS 1.1 includes support for the Power64
- architecture and aix4.3 support. The RS6000/PowerPC port now
- uses the Haifa scheduler.
- + x86: Alignment of static store data and jump targets is per
- Intel recommendations now. Various improvements throughout
- the x86 port to improve performance on Pentium processors.
- Conditional move support has been fixed and enabled for PPro
- processors. The x86 port also better supports 64bit
- operations now.
- + MIPS has improved multiply/multiply-add support and now
- includes mips16 ISA support.
- + M68k has many micro-optimizations and Coldfire fixes.
- * Core compiler is based on the GCC development tree from June 9,
- 1998, so we have all of the [5]features found in GCC 2.8.

-
- EGCS 1.1 Caveats
-
- * EGCS has an integrated libstdc++, but does not have an integrated
- libg++. Furthermore old libg++ releases will not work with EGCS;
- HJ Lu has made a [1]libg++ snapshot available which may work with
- EGCS.
- Note most C++ programs only need libstdc++.
- * Exception handling may not work with shared libraries,
- particularly on alphas, hppas, rs6000/powerpc and mips based
- platforms. Exception handling is known to work on x86-linux
- platforms with shared libraries.
- * Some versions of the Linux kernel have bugs which prevent them
- from being compiled or from running when compiled by EGCS. See
- [2]the FAQ for additional information.
- * In general, EGCS is more rigorous about rejecting invalid C++ code
- or deprecated C++ constructs than g++-2.7, g++-2.8 or EGCS 1.0. As
- a result it may be necessary to fix C++ code before it will
- compile with EGCS.
- * G++ is also converting toward the ISO C++ standard; as a result
- code which was previously valid (and thus accepted by other
- compilers and older versions of g++) may no longer be accepted.
- * EGCS 1.1 compiled C++ code is not binary compatible with EGCS
- 1.0.x or GCC 2.8.x due to changes necessary to support thread safe
- exception handling.

-
- May 15, 1998
-
- We are pleased to announce the release of EGCS 1.0.3.
-
- EGCS is a collaborative effort involving several groups of hackers
- using an open development model to accelerate development and testing
- of GNU compilers and runtime libraries.
-

-
- EGCS 1.0.1
-
- January 6, 1998
-
- We are pleased to announce the release of EGCS 1.0.1.
-
- EGCS is a collaborative effort involving several groups of hackers
- using an open development model to accelerate development and testing
- of GNU compilers and runtime libraries.
-
- EGCS 1.0.1 is a minor update to the EGCS 1.0 compiler to fix a few
- critical bugs and add support for Red Hat 5.0 Linux. Changes since the
- EGCS 1.0 release:
- * Add support for Red Hat 5.0 Linux and better support for Linux
- systems using glibc2.
- Many programs failed to link when compiled with EGCS 1.0 on Red
- Hat 5.0 or on systems with newer versions of glibc2. EGCS 1.0.1
- should fix these problems.
- * Compatability with both EGCS 1.0 and GCC 2.8 libgcc exception
- handling interfaces.
- To avoid future compatibility problems, we strongly urge anyone
- who is planning on distributing shared libraries that contain C++
- code to upgrade to EGCS 1.0.1 first.
- Soon after EGCS 1.0 was released, the GCC developers made some
- incompatible changes in libgcc's exception handling interfaces.
- These changes were needed to solve problems on some platforms.
- This means that GCC 2.8.0, when released, will not be seamlessly
- compatible with shared libraries built by EGCS 1.0. The reason is
- that the libgcc.a in GCC 2.8.0 will not contain a function needed
- by the old interface.
- The result of this is that there may be compatibility problems
- with shared libraries built by EGCS 1.0 when used with GCC 2.8.0.
- With EGCS 1.0.1, generated code uses the new (GCC 2.8.0)
- interface, and libgcc.a has the support routines for both the old
- and the new interfaces (so EGCS 1.0.1 and EGCS 1.0 code can be
- freely mixed, and EGCS 1.0.1 and GCC 2.8.0 code can be freely
- mixed).
- The maintainers of GCC 2.x have decided against including seamless
- support for the old interface in 2.8.0, since it was never
- "official", so to avoid future compatibility problems we recommend
- against distributing any shared libraries built by EGCS 1.0 that
- contain C++ code (upgrade to 1.0.1 and use that).
- * Various bugfixes in the x86, hppa, mips, and rs6000/ppc backends.
- The x86 changes fix code generation errors exposed when building
- glibc2 and the Linux dynamic linker (ld.so).
- The hppa change fixes a compiler abort when configured for use
- with RTEMS.
- The MIPS changes fix problems with the definition of LONG_MAX on
- newer systems, allow for command line selection of the target ABI,
- and fix one code generation problem.
- The rs6000/ppc change fixes some problems with passing structures
- to varargs/stdarg functions.
- * A few machine independent bugfixes, mostly to fix code generation
- errors when building Linux kernels or glibc.
- * Fix a few critical exception handling and template bugs in the C++
- compiler.
- * Fix Fortran namelist bug on alphas.
- * Fix build problems on x86-solaris systems.
-
- An important goal of EGCS is to allow wide scale testing of new
- features and optimizations which are still under development. However,
- EGCS has been carefully tested and should be comparable in quality to
- most GCC releases.
-
- EGCS 1.0.1 is based on an August 2, 1997 snapshot of the GCC 2.8
- development sources; it contains nearly all of the new features found
- in GCC 2.8.
-
- EGCS also contains many improvements and features not found in GCC 2.7
- and even the soon to be released GCC 2.8 compilers.

- linux systems!
- * The integrated libstdc++ library includes a verbatim copy of

- * Integrated GNU Fortran compiler based on g77-0.5.22-19970929.
- * Vast improvements in the C++ compiler; so many they have [2]page
- of their own!
- * Integrated C++ runtime libraries, including support for most major
- linux systems!
- * New instruction scheduler from IBM Haifa which includes support
- for function wide instruction scheduling as well as superscalar
- scheduling.
- * Significantly improved alias analysis code.
- * Improved register allocation for two address machines.
- * Significant code generation improvements for Fortran code on
- Alphas
- * Various optimizations from the g77 project as well as improved
- loop optimizations.
- * Dwarf2 debug format support for some targets.
- * egcs libstdc++ includes the SGI STL implementation without
- changes.
- * As a result of these and other changes, egcs libstc++ is not
- binary compatible with previous releases of libstdc++.
- * Various new ports -- UltraSPARC, Irix6.2 & Irix6.3 support, The
- SCO Openserver 5 family (5.0.{0,2,4} and Internet FastStart 1.0
- and 1.1), Support for RTEMS on several embedded targets, Support
- for arm-linux, Mitsubishi M32R, Hitachi H8/S, Matsushita MN102 and
- MN103, NEC V850, Sparclet, Solaris & Linux on PowerPCs, etc.
- * Integrated testsuites for gcc, g++, g77, libstdc++ and libio.
- * RS6000/PowerPC ports generate code which can run on all
- RS6000/PowerPC variants by default.
- * -mcpu= and -march= switches for the x86 port to allow better
- control over how the x86 port generates code.
- * Includes the template repository patch (aka repo patch); note the
- new template code makes repo obsolete for ELF systems using gnu-ld
- such as Linux.
- * Plus the usual assortment of bugfixes and improvements.

-
- EGCS 1.0 Caveats
-
- * EGCS has an integrated libstdc++, but does not have an integrated
- libg++. Furthermore old libg++ releases will not work with egc; HJ
- Lu has made a [1]libg++ snapshot available which may work with
- EGCS.
- Note most C++ programs only need libstdc++.
- * Note that using -pedantic or -Wreturn-type can cause an explosion
- in the amount of memory needed for template-heavy C++ code, such
- as code that uses STL. Also note that -Wall includes
- -Wreturn-type, so if you use -Wall you will need to specify
- -Wno-return-type to turn it off.
- * Exception handling may not work with shared libraries,
- particularly on alphas, hppas, and mips based platforms. Exception
- handling is known to work on x86-linux platforms with shared
- libraries.
- * Some versions of the Linux kernel have bugs which prevent them
- from being compiled or from running when compiled by EGCS. See
- [2]the FAQ for additional information.
- * In general, EGCS is more rigorous about rejecting invalid C++ code
- or deprecated C++ constructs than G++ 2.7. As a result it may be
- necessary to fix C++ code before it will compile with EGCS.
- * G++ is also aggressively tracking the C++ standard; as a result
- code which was previously valid (and thus accepted by other
- compilers and older versions of G++) may no longer be accepted.
- * EGCS 1.0 may not work with Red Hat Linux 5.0 on all targets. EGCS
- 1.0.x and later releases should work with Red Hat Linux 5.0.
