gcc/boehm-gc/Makefile.orig

# Primary targets:
# gc.a - builds basic library
# libgc.a - builds library for use with g++ "-fgc-keyword" extension
# c++ - adds C++ interface to library
# cords - adds cords (heavyweight strings) to library
# test - prints porting information, then builds basic version of gc.a,
#      	 and runs some tests of collector and cords.  Does not add cords or
#	 c++ interface to gc.a
# cord/de - builds dumb editor based on cords.
ABI_FLAG=
CC=cc $(ABI_FLAG)
CXX=CC $(ABI_FLAG)
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 for as if you specify
#  it for the C compiler.

CFLAGS= -O -DATOMIC_UNCOLLECTABLE -DNO_SIGNALS -DALL_INTERIOR_POINTERS -DNO_EXECUTE_PERMISSION -DSILENT

# Setjmp_test may yield overly optimistic results when compiled
# without optimization.
# -DSILENT disables statistics printing, and improves performance.
# -DCHECKSUMS reports on erroneously clear dirty bits, and unexpectedly
#   altered stubborn objects, at substantial performance cost.
#   Use only for incremental collector debugging.
# -DFIND_LEAK causes the collector to assume that all inaccessible
#   objects should have been explicitly deallocated, and reports exceptions.
#   Finalization and the test program are not usable in this mode.
# -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.)
#   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.
# -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,
#   usually causing it to use less space in such situations.
#   Incremental collection no longer works in this case.
# -DLARGE_CONFIG tunes the collector for unusually large heaps.
#   Necessary for heaps larger than about 500 MB on most machines.
#   Recommended for heaps larger than about 64 MB.
# -DDONT_ADD_BYTE_AT_END is meaningful only with
#   -DALL_INTERIOR_POINTERS.  Normally -DALL_INTERIOR_POINTERS
#   causes all objects to be padded so that pointers just past the end of
#   an object can be recognized.  This can be expensive.  (The padding
#   is normally more than one byte due to alignment constraints.)
#   -DDONT_ADD_BYTE_AT_END disables the padding.
# -DNO_SIGNALS does not disable signals during critical parts of
#   the GC process.  This is no less correct than many malloc 
#   implementations, and it sometimes has a significant performance
#   impact.  However, it is dangerous for many not-quite-ANSI C
#   programs that call things like printf in asynchronous signal handlers.
# -DNO_EXECUTE_PERMISSION may cause some or all of the heap to not
#   have execute permission, i.e. it may be impossible to execute
#   code from the heap.  Currently this only affects the incremental
#   collector on UNIX machines.  It may greatly improve its performance,
#   since this may avoid some expensive cache synchronization.
# -DOPERATOR_NEW_ARRAY declares that the C++ compiler supports the
#   new syntax "operator new[]" for allocating and deleting arrays.
#   See gc_cpp.h for details.  No effect on the C part of the collector.
#   This is defined implicitly in a few environments.
# -DREDIRECT_MALLOC=X causes malloc, realloc, and free to be defined
#   as aliases for X, GC_realloc, and GC_free, respectively.
#   Calloc is redefined in terms of the new malloc.  X should
#   be either GC_malloc or GC_malloc_uncollectable.
#   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,
#   since some ports use malloc or calloc to obtain system memory.
#   (Probably works for UNIX, and win32.)
# -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.
#   Reduces code size slightly at the expense of debuggability.
# -DJAVA_FINALIZATION makes it somewhat safer to finalize objects out of
#   order by specifying a nonstandard finalization mark procedure  (see
#   finalize.c).  Objects reachable from finalizable objects will be marked
#   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.
