43: // Flags for building libgc.a -- the last two are required.
44: //
45: // Setjmp_test may yield overly optimistic results when compiled
46: // without optimization.
47: // -DSILENT disables statistics printing, and improves performance.
48: // -DCHECKSUMS reports on erroneously clear dirty bits, and unexpectedly
49: // altered stubborn objects, at substantial performance cost.
50: // Use only for incremental collector debugging.
51: // -DFIND_LEAK causes the collector to assume that all inaccessible
52: // objects should have been explicitly deallocated, and reports exceptions.
53: // Finalization and the test program are not usable in this mode.
54: // -DSOLARIS_THREADS enables support for Solaris (thr_) threads.
55: // (Clients should also define SOLARIS_THREADS and then include
56: // gc.h before performing thr_ or GC_ operations.)
57: // This is broken on nonSPARC machines.
58: // -DALL_INTERIOR_POINTERS allows all pointers to the interior
59: // of objects to be recognized. (See gc_priv.h for consequences.)
60: // -DSMALL_CONFIG tries to tune the collector for small heap sizes,
61: // usually causing it to use less space in such situations.
62: // Incremental collection no longer works in this case.
63: // -DLARGE_CONFIG tunes the collector for unusually large heaps.
64: // Necessary for heaps larger than about 500 MB on most machines.
65: // Recommended for heaps larger than about 64 MB.
66: // -DDONT_ADD_BYTE_AT_END is meaningful only with
67: // -DALL_INTERIOR_POINTERS. Normally -DALL_INTERIOR_POINTERS
68: // causes all objects to be padded so that pointers just past the end of
69: // an object can be recognized. This can be expensive. (The padding
70: // is normally more than one byte due to alignment constraints.)
71: // -DDONT_ADD_BYTE_AT_END disables the padding.
72: // -DNO_SIGNALS does not disable signals during critical parts of
73: // the GC process. This is no less correct than many malloc
74: // implementations, and it sometimes has a significant performance
75: // impact. However, it is dangerous for many not-quite-ANSI C
76: // programs that call things like printf in asynchronous signal handlers.
1.3 ! noro 77: // -DGC_OPERATOR_NEW_ARRAY declares that the C++ compiler supports the
1.1 noro 78: // new syntax "operator new[]" for allocating and deleting arrays.
79: // See gc_cpp.h for details. No effect on the C part of the collector.
80: // This is defined implicitly in a few environments.
81: // -DREDIRECT_MALLOC=X causes malloc, realloc, and free to be defined
82: // as aliases for X, GC_realloc, and GC_free, respectively.
83: // Calloc is redefined in terms of the new malloc. X should
84: // be either GC_malloc or GC_malloc_uncollectable.
85: // The former is occasionally useful for working around leaks in code
86: // you don't want to (or can't) look at. It may not work for
87: // existing code, but it often does. Neither works on all platforms,
88: // since some ports use malloc or calloc to obtain system memory.
89: // (Probably works for UNIX, and win32.)
90: // -DNO_DEBUG removes GC_dump and the debugging routines it calls.
91: // Reduces code size slightly at the expense of debuggability.
