   1 # Primary targets:
   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.

  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
  72 #   -DREDIRECT_MALLOC.
  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
  80 #   these semantics.
  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.
