# The above doesn't work with gas, which doesn't run cpp.
# Define AS as `gcc -c -x assembler-with-cpp' instead.
-# Under Irix 6, you will have to specify the ABI (-o32, -n32, or -64)
-# if you use something other than the default ABI on your machine.
# Redefining srcdir allows object code for the nonPCR version of the collector

# To build the parallel collector on Linux, add to the above:

-# To build the parallel collector n a static library on HP/UX, add to the above:

# gc.h before performing thr_ or dl* or GC_ operations.)
# Must also define -D_REENTRANT.
# -DGC_SOLARIS_PTHREADS enables support for Solaris pthreads.
-# Define SOLARIS_THREADS as well.
+# (Internally this define GC_SOLARIS_THREADS as well.)
# -DGC_IRIX_THREADS enables support for Irix pthreads. See README.irix.
# -DGC_HPUX_THREADS enables support for HP/UX 11 pthreads.
# Also requires -D_REENTRANT or -D_POSIX_C_SOURCE=199506L. See README.hp.
# -DGC_LINUX_THREADS enables support for Xavier Leroy's Linux threads.
# see README.linux. -D_REENTRANT may also be required.
+# -DGC_OSF1_THREADS enables support for Tru64 pthreads.
+# -DGC_FREEBSD_THREADS enables support for FreeBSD pthreads.
+# Appeared to run into some underlying thread problems.
+# -DGC_DARWIN_THREADS enables support for Mac OS X pthreads.
+# -DGC_AIX_THREADS enables support for IBM AIX threads.
+# -DGC_DGUX386_THREADS enables support for DB/UX on I386 threads.
+# See README.DGUX386.
+# -DGC_WIN32_THREADS enables support for win32 threads. That makes sense
+# for this Makefile only under Cygwin.
+# -DGC_THREADS should set the appropriate one of the above macros.
+# It assumes pthreads for Solaris.
# -DALL_INTERIOR_POINTERS allows all pointers to the interior
# of objects to be recognized. (See gc_priv.h for consequences.)
# Alternatively, GC_all_interior_pointers can be set at process
# See gc_cpp.h for details. No effect on the C part of the collector.
# This is defined implicitly in a few environments. Must also be defined
# by clients that use gc_cpp.h.
-# -DREDIRECT_MALLOC=X causes malloc, realloc, and free to be
-# defined as aliases for X, GC_realloc, and GC_free, respectively.
+# -DREDIRECT_MALLOC=X causes malloc to be defined as alias for X.
+# Unless the following macros are defined, realloc is also redirected
+# to GC_realloc, and free is redirected to GC_free.
# Calloc and strdup are redefined in terms of the new malloc. X should
# be either GC_malloc or GC_malloc_uncollectable, or
# GC_debug_malloc_replacement. (The latter invokes GC_debug_malloc
# with dummy source location information, but still results in
-# properly remembered call stacks on Linux/X86 and Solaris/SPARC.)
+# properly remembered call stacks on Linux/X86 and Solaris/SPARC.
+# It requires that the following two macros also be used.)
# The former is occasionally useful for working around leaks in code
# you don't want to (or can't) look at. It may not work for
# existing code, but it often does. Neither works on all platforms,
# The canonical use is -DREDIRECT_REALLOC=GC_debug_realloc_replacement,
# together with -DREDIRECT_MALLOC=GC_debug_malloc_replacement to
# generate leak reports with call stacks for both malloc and realloc.
+# This also requires the following:
+# -DREDIRECT_FREE=X causes free to be redirected to X. The
+# canonical use is -DREDIRECT_FREE=GC_debug_free.
# -DIGNORE_FREE turns calls to free into a noop. Only useful with
# -DREDIRECT_MALLOC.
# -DNO_DEBUGGING removes GC_dump and the debugging routines it calls.
# this facility is only used in a few places. It is intended primarily
# for debugging of the garbage collector itself, but could also
# -DDBG_HDRS_ALL Make sure that all objects have debug headers. Increases
-# the reliability (from 99.9999% to 100%) of some of the debugging
+# the reliability (from 99.9999% to 100% mod. bugs) of some of the debugging
# code (especially KEEP_BACK_PTRS). Makes -DSHORT_DBG_HDRS possible.
# Assumes that all client allocation is done through debugging
# allocators.
# 15% or so.
# -DUSE_3DNOW_PREFETCH causes the collector to issue AMD 3DNow style
# prefetch instructions. Same restrictions as USE_I686_PREFETCH.
-# UNTESTED!!
-# -DGC_USE_LD_WRAP in combination with the gld flags listed in README.linux
+# Minimally tested. Didn't appear to be an obvious win on a K6-2/500.
+# -DUSE_PPC_PREFETCH causes the collector to issue PowerPC style
+# prefetch instructions. No effect except on PowerPC OS X platforms.
+# Performance impact untested.
+# -DGC_USE_LD_WRAP in combination with the old flags listed in README.linux
# causes the collector some system and pthread calls in a more transparent
# fashion than the usual macro-based approach. Requires GNU ld, and
# currently probably works only with Linux.
# -DTHREAD_LOCAL_ALLOC defines GC_local_malloc(), GC_local_malloc_atomic()
# and GC_local_gcj_malloc(). Needed for gc_gcj.h interface. These allocate
# in a way that usually does not involve acquisition of a global lock.
-# Currently requires -DGC_LINUX_THREADS, but should be easy to port to
-# other pthreads environments. Recommended for multiprocessors.
+# Currently works only on platforms such as Linux which use pthread_support.c.
+# Recommended for multiprocessors.
+# -DUSE_COMPILER_TLS causes thread local allocation to use compiler-supported
+# "__thread" thread-local variables. This is the default in HP/UX. It
+# may help performance on recent Linux installations. (It failed for
+# me on RedHat 8, but appears to work on RedHat 9.)
# -DPARALLEL_MARK allows the marker to run in multiple threads. Recommended
# for multiprocessors. Currently requires Linux on X86 or IA64, though
# support for other Posix platforms should be fairly easy to add,
# -DSTUBBORN_ALLOC allows allocation of "hard to change" objects, and thus
# makes incremental collection easier. Was enabled by default until 6.0.
# Rarely used, to my knowledge.
+# -DHANDLE_FORK attempts to make GC_malloc() work in a child process fork()ed
+# from a multithreaded parent. Currently only supported by pthread_support.c.
+# (Similar code should work on Solaris or Irix, but it hasn't been tried.)
+# -DTEST_WITH_SYSTEM_MALLOC causes gctest to allocate (and leak) large chunks
+# of memory with the standard system malloc. This will cause the root
+# set and collected heap to grow significantly if malloced memory is
+# somehow getting traced by the collector. This has no impact on the
+# generated library; it only affects the test.
+# -DPOINTER_MASK=0x... causes candidate pointers to be ANDed with the
+# given mask before being considered. If either this or the following
+# macro is defined, it will be assumed that all pointers stored in
+# the heap need to be processed this way. Stack and register pointers
+# will be considered both with and without processing.
+# These macros are normally needed only to support systems that use
+# high-order pointer tags. EXPERIMENTAL.
+# -DPOINTER_SHIFT=n causes the collector to left shift candidate pointers
+# by the indicated amount before trying to interpret them. Applied
+# after POINTER_MASK. EXPERIMENTAL. See also the preceding macro.
+# -DDARWIN_DONT_PARSE_STACK Causes the Darwin port to discover thread
+# stack bounds in the same way as other pthread ports, without trying to
+# walk the frames onthe stack. This is recommended only as a fallback
+# for applications that don't support proper stack unwinding.
