2 # gc.a - builds basic library
3 # libgc.a - builds library for use with g++ "-fgc-keyword" extension
4 # c++ - adds C++ interface to library
5 # cords - adds cords (heavyweight strings) to library
6 # test - prints porting information, then builds basic version of gc.a,
7 # and runs some tests of collector and cords. Does not add cords or
8 # c++ interface to gc.a
9 # cord/de$(EXE_SUFFIX) - builds dumb editor based on cords.
18 CFLAGS= -O -DNO_SIGNALS -DALL_INTERIOR_POINTERS -DSILENT -DATOMIC_UNCOLLECTABLE
20 # Setjmp_test may yield overly optimistic results when compiled
21 # without optimization.
22 # -DSILENT disables statistics printing, and improves performance.
23 # -DCHECKSUMS reports on erroneously clear dirty bits, and unexpectedly
24 # altered stubborn objects, at substantial performance cost.
25 # Use only for incremental collector debugging.
26 # -DFIND_LEAK causes the collector to assume that all inaccessible
27 # objects should have been explicitly deallocated, and reports exceptions.
28 # Finalization and the test program are not usable in this mode.
29 # -DSOLARIS_THREADS enables support for Solaris (thr_) threads.
30 # (Clients should also define SOLARIS_THREADS and then include
31 # gc.h before performing thr_ or dl* or GC_ operations.)
32 # This is broken on nonSPARC machines.
33 # -DIRIX_THREADS enables support for Irix pthreads. See README.irix.
34 # -DALL_INTERIOR_POINTERS allows all pointers to the interior
35 # of objects to be recognized. (See gc_priv.h for consequences.)
36 # -DSMALL_CONFIG tries to tune the collector for small heap sizes,
37 # usually causing it to use less space in such situations.
38 # Incremental collection no longer works in this case.
39 # -DLARGE_CONFIG tunes the collector for unusually large heaps.
40 # Necessary for heaps larger than about 500 MB on most machines.
41 # Recommended for heaps larger than about 64 MB.
42 # -DDONT_ADD_BYTE_AT_END is meaningful only with
43 # -DALL_INTERIOR_POINTERS. Normally -DALL_INTERIOR_POINTERS
44 # causes all objects to be padded so that pointers just past the end of
45 # an object can be recognized. This can be expensive. (The padding
46 # is normally more than one byte due to alignment constraints.)
47 # -DDONT_ADD_BYTE_AT_END disables the padding.
48 # -DNO_SIGNALS does not disable signals during critical parts of
49 # the GC process. This is no less correct than many malloc
50 # implementations, and it sometimes has a significant performance
51 # impact. However, it is dangerous for many not-quite-ANSI C
52 # programs that call things like printf in asynchronous signal handlers.
53 # -DNO_EXECUTE_PERMISSION may cause some or all of the heap to not
54 # have execute permission, i.e. it may be impossible to execute
55 # code from the heap. Currently this only affects the incremental
56 # collector on UNIX machines. It may greatly improve its performance,
57 # since this may avoid some expensive cache synchronization.
58 # -DOPERATOR_NEW_ARRAY declares that the C++ compiler supports the
59 # new syntax "operator new[]" for allocating and deleting arrays.
60 # See gc_cpp.h for details. No effect on the C part of the collector.
61 # This is defined implicitly in a few environments.
62 # -DREDIRECT_MALLOC=X causes malloc, realloc, and free to be defined
63 # as aliases for X, GC_realloc, and GC_free, respectively.
64 # Calloc is redefined in terms of the new malloc. X should
65 # be either GC_malloc or GC_malloc_uncollectable.
66 # The former is occasionally useful for working around leaks in code
67 # you don't want to (or can't) look at. It may not work for
68 # existing code, but it often does. Neither works on all platforms,
69 # since some ports use malloc or calloc to obtain system memory.
70 # (Probably works for UNIX, and win32.)
71 # -DIGNORE_FREE turns calls to free into a noop. Only useful with
73 # -DNO_DEBUGGING removes GC_dump and the debugging routines it calls.
74 # Reduces code size slightly at the expense of debuggability.
75 # -DJAVA_FINALIZATION makes it somewhat safer to finalize objects out of
76 # order by specifying a nonstandard finalization mark procedure (see
77 # finalize.c). Objects reachable from finalizable objects will be marked
78 # in a sepearte postpass, and hence their memory won't be reclaimed.
79 # Not recommended unless you are implementing a language that specifies
81 # -DATOMIC_UNCOLLECTABLE includes code for GC_malloc_atomic_uncollectable.
82 # This is useful if either the vendor malloc implementation is poor,
83 # or if REDIRECT_MALLOC is used.

96 # to be generated in different directories. In this case, the destination directory
97 # should contain a copy of the original include directory.
