+# For dynamic library builds, it may be necessary to add flags to generate
+# PIC code, e.g. -fPIC on Linux.
# Setjmp_test may yield overly optimistic results when compiled
# without optimization.
# -DSOLARIS_THREADS enables support for Solaris (thr_) threads.
# (Clients should also define SOLARIS_THREADS and then include
# gc.h before performing thr_ or dl* or GC_ operations.)
-# This is broken on nonSPARC machines.
+# Must also define -D_REENTRANT.
+# -D_SOLARIS_PTHREADS enables support for Solaris pthreads.
+# Define SOLARIS_THREADS as well.
# -DIRIX_THREADS enables support for Irix pthreads. See README.irix.
+# -DLINUX_THREADS enables support for Xavier Leroy's Linux threads.
+# see README.linux. -D_REENTRANT may also be required.
# -DALL_INTERIOR_POINTERS allows all pointers to the interior
# of objects to be recognized. (See gc_priv.h for consequences.)
# -DSMALL_CONFIG tries to tune the collector for small heap sizes,
# in a sepearte postpass, and hence their memory won't be reclaimed.
# Not recommended unless you are implementing a language that specifies
# these semantics.
+# -DFINALIZE_ON_DEMAND causes finalizers to be run only in response
+# to explicit GC_invoke_finalizers() calls.
# -DATOMIC_UNCOLLECTABLE includes code for GC_malloc_atomic_uncollectable.
# This is useful if either the vendor malloc implementation is poor,
# or if REDIRECT_MALLOC is used.
+# -DHBLKSIZE=ddd, where ddd is a power of 2 between 512 and 16384, explicitly
+# sets the heap block size. Each heap block is devoted to a single size and
+# kind of object. For the incremental collector it makes sense to match
+# the most likely page size. Otherwise large values result in more
+# fragmentation, but generally better performance for large heaps.
+# -DUSE_MMAP use MMAP instead of sbrk to get new memory.
+# Works for Solaris and Irix.
+# -DMMAP_STACKS (for Solaris threads) Use mmap from /dev/zero rather than
+# GC_scratch_alloc() to get stack memory.
+# -DPRINT_BLACK_LIST Whenever a black list entry is added, i.e. whenever
+# the garbage collector detects a value that looks almost, but not quite,
+# like a pointer, print both the address containing the value, and the
+# value of the near-bogus-pointer. Can be used to identifiy regions of
+# memory that are likely to contribute misidentified pointers.
+# -DOLD_BLOCK_ALLOC Use the old, possibly faster, large block
+# allocation strategy. The new strategy tries harder to minimize
+# fragmentation, sometimes at the expense of spending more time in the
+# large block allocator and/or collecting more frequently.
+# If you expect the allocator to promtly use an explicitly expanded
+# heap, this is highly recommended.
