ABI_FLAG=
+# ABI_FLAG should be the cc flag that specifies the ABI. On most
+# platforms this will be the empty string. Possible values:
+# +DD64 for 64-bit executable on HP/UX.
+# -n32, -n64, -o32 for SGI/MIPS ABIs.
+
+AS_ABI_FLAG=$(ABI_FLAG)
+# ABI flag for assembler. On HP/UX this is +A64 for 64 bit
+# executables.

CC=cc $(ABI_FLAG)
CXX=g++ $(ABI_FLAG)
-AS=as $(ABI_FLAG)
+AS=as $(AS_ABI_FLAG)
# 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 be generated in different directories.
# -DGC_LINUX_THREADS -DPARALLEL_MARK -DTHREAD_LOCAL_ALLOC
# To build the parallel collector in a static library on HP/UX,
# add to the above:
-# -DGC_HPUX_THREADS -DPARALLEL_MARK -DTHREAD_LOCAL_ALLOC -DUSE_HPUX_TLS -D_POSIX_C_SOURCE=199506L
+# -DGC_HPUX_THREADS -DPARALLEL_MARK -DTHREAD_LOCAL_ALLOC -D_POSIX_C_SOURCE=199506L -mt
# To build the thread-safe collector on Tru64, add to the above:
# -pthread -DGC_OSF1_THREADS
# 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. Untested.
-# -DGC_FREEBSD_THREADS enables support for FreeBSD pthreads. Untested.
+# -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. Untested.
+# -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
# 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.
# -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,
# -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.
