boehm-gc/Makefile.direct

   1 # This is the original manually generated Makefile.  It may still be used
   2 # to build the collector.
   3 #
   4 # Primary targets:
   5 # gc.a - builds basic library
   6 # c++ - adds C++ interface to library
   7 # cords - adds cords (heavyweight strings) to library
   8 # test - prints porting information, then builds basic version of gc.a,
   9 #        and runs some tests of collector and cords.  Does not add cords or
  10 #        c++ interface to gc.a
  11 # cord/de - builds dumb editor based on cords.
  12 ABI_FLAG=
  13 # ABI_FLAG should be the cc flag that specifies the ABI.  On most
  14 # platforms this will be the empty string.  Possible values:
  15 # +DD64 for 64-bit executable on HP/UX.
  16 # -n32, -n64, -o32 for SGI/MIPS ABIs.
  17
  18 AS_ABI_FLAG=$(ABI_FLAG)
  19 # ABI flag for assembler.  On HP/UX this is +A64 for 64 bit
  20 # executables.
  21
  22 CC=cc $(ABI_FLAG)
  23 CXX=g++ $(ABI_FLAG)
  24 AS=as $(AS_ABI_FLAG)
  25 #  The above doesn't work with gas, which doesn't run cpp.
  26 #  Define AS as `gcc -c -x assembler-with-cpp' instead.
  27
  28 # Redefining srcdir allows object code for the nonPCR version of the collector
  29 # to be generated in different directories.
  30 srcdir= .
  31 VPATH= $(srcdir)
  32
  33 CFLAGS= -O -I$(srcdir)/include -DATOMIC_UNCOLLECTABLE -DNO_SIGNALS -DNO_EXECUTE_PERMISSION -DSILENT -DALL_INTERIOR_POINTERS
  34
  35 # To build the parallel collector on Linux, add to the above:
  36 # -DGC_LINUX_THREADS -DPARALLEL_MARK -DTHREAD_LOCAL_ALLOC
  37 # To build the parallel collector n a static library on HP/UX, add to the above:
  38 # -DGC_HPUX_THREADS -DPARALLEL_MARK -DTHREAD_LOCAL_ALLOC -DUSE_HPUX_TLS -D_POSIX_C_SOURCE=199506L
  39
  40 # HOSTCC and HOSTCFLAGS are used to build executables that will be run as
  41 # part of the build process, i.e. on the build machine.  These will usually
  42 # be the same as CC and CFLAGS, except in a cross-compilation environment.
  43 # Note that HOSTCFLAGS should include any -D flags that affect thread support.
  44 HOSTCC=$(CC)
  45 HOSTCFLAGS=$(CFLAGS)
  46
  47 # For dynamic library builds, it may be necessary to add flags to generate
  48 # PIC code, e.g. -fPIC on Linux.
  49
  50 # Setjmp_test may yield overly optimistic results when compiled
  51 # without optimization.
  52
  53 # These define arguments influence the collector configuration:
  54 # -DSILENT disables statistics printing, and improves performance.
  55 # -DFIND_LEAK causes GC_find_leak to be initially set.
  56 #   This causes the collector to assume that all inaccessible
  57 #   objects should have been explicitly deallocated, and reports exceptions.
  58 #   Finalization and the test program are not usable in this mode.
  59 # -DGC_SOLARIS_THREADS enables support for Solaris (thr_) threads.
  60 #   (Clients should also define GC_SOLARIS_THREADS and then include
  61 #   gc.h before performing thr_ or dl* or GC_ operations.)
  62 #   Must also define -D_REENTRANT.
  63 # -DGC_SOLARIS_PTHREADS enables support for Solaris pthreads.
  64 #   (Internally this define GC_SOLARIS_THREADS as well.)
  65 # -DGC_IRIX_THREADS enables support for Irix pthreads.  See README.irix.
  66 # -DGC_HPUX_THREADS enables support for HP/UX 11 pthreads.
  67 #   Also requires -D_REENTRANT or -D_POSIX_C_SOURCE=199506L. See README.hp.
  68 # -DGC_LINUX_THREADS enables support for Xavier Leroy's Linux threads.
  69 #   see README.linux.  -D_REENTRANT may also be required.
  70 # -DGC_OSF1_THREADS enables support for Tru64 pthreads.  Untested.
  71 # -DGC_FREEBSD_THREADS enables support for FreeBSD pthreads.  Untested.
  72 #   Appeared to run into some underlying thread problems.
  73 # -DALL_INTERIOR_POINTERS allows all pointers to the interior
  74 #   of objects to be recognized.  (See gc_priv.h for consequences.)
  75 #   Alternatively, GC_all_interior_pointers can be set at process
  76 #   initialization time.
  77 # -DSMALL_CONFIG tries to tune the collector for small heap sizes,
  78 #   usually causing it to use less space in such situations.
  79 #   Incremental collection no longer works in this case.
  80 # -DLARGE_CONFIG tunes the collector for unusually large heaps.
  81 #   Necessary for heaps larger than about 500 MB on most machines.
  82 #   Recommended for heaps larger than about 64 MB.
  83 # -DDONT_ADD_BYTE_AT_END is meaningful only with -DALL_INTERIOR_POINTERS or
  84 #   GC_all_interior_pointers = 1.  Normally -DALL_INTERIOR_POINTERS
  85 #   causes all objects to be padded so that pointers just past the end of
  86 #   an object can be recognized.  This can be expensive.  (The padding
  87 #   is normally more than one byte due to alignment constraints.)
  88 #   -DDONT_ADD_BYTE_AT_END disables the padding.
  89 # -DNO_SIGNALS does not disable signals during critical parts of
  90 #   the GC process.  This is no less correct than many malloc
  91 #   implementations, and it sometimes has a significant performance
  92 #   impact.  However, it is dangerous for many not-quite-ANSI C
  93 #   programs that call things like printf in asynchronous signal handlers.
  94 #   This is on by default.  Turning it off has not been extensively tested with
  95 #   compilers that reorder stores.  It should have been.
  96 # -DNO_EXECUTE_PERMISSION may cause some or all of the heap to not
  97 #   have execute permission, i.e. it may be impossible to execute
  98 #   code from the heap.  Currently this only affects the incremental
  99 #   collector on UNIX machines.  It may greatly improve its performance,
 100 #   since this may avoid some expensive cache synchronization.
 101 # -DGC_NO_OPERATOR_NEW_ARRAY declares that the C++ compiler does not support
 102 #   the  new syntax "operator new[]" for allocating and deleting arrays.
 103 #   See gc_cpp.h for details.  No effect on the C part of the collector.
 104 #   This is defined implicitly in a few environments.  Must also be defined
 105 #   by clients that use gc_cpp.h.
 106 # -DREDIRECT_MALLOC=X causes malloc, realloc, and free to be
 107 #   defined as aliases for X, GC_realloc, and GC_free, respectively.
 108 #   Calloc and strdup are redefined in terms of the new malloc.  X should
 109 #   be either GC_malloc or GC_malloc_uncollectable, or
 110 #   GC_debug_malloc_replacement.  (The latter invokes GC_debug_malloc
 111 #   with dummy source location information, but still results in
 112 #   properly remembered call stacks on Linux/X86 and Solaris/SPARC.)
 113 #   The former is occasionally useful for working around leaks in code
 114 #   you don't want to (or can't) look at.  It may not work for
 115 #   existing code, but it often does.  Neither works on all platforms,
 116 #   since some ports use malloc or calloc to obtain system memory.
 117 #   (Probably works for UNIX, and win32.)  If you build with DBG_HDRS_ALL,
 118 #   you should only use GC_debug_malloc_replacement as a malloc
 119 #   replacement.
 120 # -DREDIRECT_REALLOC=X causes GC_realloc to be redirected to X.
 121 #   The canonical use is -DREDIRECT_REALLOC=GC_debug_realloc_replacement,
 122 #   together with -DREDIRECT_MALLOC=GC_debug_malloc_replacement to
 123 #   generate leak reports with call stacks for both malloc and realloc.
 124 # -DIGNORE_FREE turns calls to free into a noop.  Only useful with
 125 #   -DREDIRECT_MALLOC.
 126 # -DNO_DEBUGGING removes GC_dump and the debugging routines it calls.
 127 #   Reduces code size slightly at the expense of debuggability.
 128 # -DJAVA_FINALIZATION makes it somewhat safer to finalize objects out of
 129 #   order by specifying a nonstandard finalization mark procedure  (see
 130 #   finalize.c).  Objects reachable from finalizable objects will be marked
 131 #   in a sepearte postpass, and hence their memory won't be reclaimed.
 132 #   Not recommended unless you are implementing a language that specifies
 133 #   these semantics.  Since 5.0, determines only only the initial value
 134 #   of GC_java_finalization variable.
 135 # -DFINALIZE_ON_DEMAND causes finalizers to be run only in response
 136 #   to explicit GC_invoke_finalizers() calls.
 137 #   In 5.0 this became runtime adjustable, and this only determines the
 138 #   initial value of GC_finalize_on_demand.
 139 # -DATOMIC_UNCOLLECTABLE includes code for GC_malloc_atomic_uncollectable.
 140 #   This is useful if either the vendor malloc implementation is poor,
 141 #   or if REDIRECT_MALLOC is used.
 142 # -DHBLKSIZE=ddd, where ddd is a power of 2 between 512 and 16384, explicitly
 143 #   sets the heap block size.  Each heap block is devoted to a single size and
 144 #   kind of object.  For the incremental collector it makes sense to match
 145 #   the most likely page size.  Otherwise large values result in more
 146 #   fragmentation, but generally better performance for large heaps.
 147 # -DUSE_MMAP use MMAP instead of sbrk to get new memory.
 148 #   Works for Solaris and Irix.
 149 # -DUSE_MUNMAP causes memory to be returned to the OS under the right
 150 #   circumstances.  This currently disables VM-based incremental collection.
 151 #   This is currently experimental, and works only under some Unix,
 152 #   Linux and Windows versions.
 153 # -DMMAP_STACKS (for Solaris threads) Use mmap from /dev/zero rather than
 154 #   GC_scratch_alloc() to get stack memory.
 155 # -DPRINT_BLACK_LIST Whenever a black list entry is added, i.e. whenever
 156 #   the garbage collector detects a value that looks almost, but not quite,
 157 #   like a pointer, print both the address containing the value, and the
 158 #   value of the near-bogus-pointer.  Can be used to identifiy regions of
 159 #   memory that are likely to contribute misidentified pointers.
 160 # -DKEEP_BACK_PTRS Add code to save back pointers in debugging headers
 161 #   for objects allocated with the debugging allocator.  If all objects
 162 #   through GC_MALLOC with GC_DEBUG defined, this allows the client
 163 #   to determine how particular or randomly chosen objects are reachable
 164 #   for debugging/profiling purposes.  The gc_backptr.h interface is
 165 #   implemented only if this is defined.
 166 # -DGC_ASSERTIONS Enable some internal GC assertion checking.  Currently
 167 #   this facility is only used in a few places.  It is intended primarily
 168 #   for debugging of the garbage collector itself, but could also
 169 # -DDBG_HDRS_ALL Make sure that all objects have debug headers.  Increases
 170 #   the reliability (from 99.9999% to 100%) of some of the debugging
 171 #   code (especially KEEP_BACK_PTRS).  Makes -DSHORT_DBG_HDRS possible.
 172 #   Assumes that all client allocation is done through debugging
 173 #   allocators.
 174 # -DSHORT_DBG_HDRS Assume that all objects have debug headers.  Shorten
 175 #   the headers to minimize object size, at the expense of checking for
 176 #   writes past the end of an object.  This is intended for environments
 177 #   in which most client code is written in a "safe" language, such as
 178 #   Scheme or Java.  Assumes that all client allocation is done using
 179 #   the GC_debug_ functions, or through the macros that expand to these,
 180 #   or by redirecting malloc to GC_debug_malloc_replacement.
 181 #   (Also eliminates the field for the requested object size.)
 182 #   occasionally be useful for debugging of client code.  Slows down the
 183 #   collector somewhat, but not drastically.
 184 # -DSAVE_CALL_COUNT=<n> Set the number of call frames saved with objects
 185 #   allocated through the debugging interface.  Affects the amount of
 186 #   information generated in leak reports.  Only matters on platforms
 187 #   on which we can quickly generate call stacks, currently Linux/(X86 & SPARC)
 188 #   and Solaris/SPARC and platforms that provide execinfo.h.
 189 #   Default is zero.  On X86, client
 190 #   code should NOT be compiled with -fomit-frame-pointer.
 191 # -DSAVE_CALL_NARGS=<n> Set the number of functions arguments to be
 192 #   saved with each call frame.  Default is zero.  Ignored if we
 193 #   don't know how to retrieve arguments on the platform.
 194 # -DCHECKSUMS reports on erroneously clear dirty bits, and unexpectedly
 195 #   altered stubborn objects, at substantial performance cost.
 196 #   Use only for debugging of the incremental collector.
 197 # -DGC_GCJ_SUPPORT includes support for gcj (and possibly other systems
 198 #   that include a pointer to a type descriptor in each allocated object).
 199 #   Building this way requires an ANSI C compiler.
 200 # -DUSE_I686_PREFETCH causes the collector to issue Pentium III style
 201 #   prefetch instructions.  No effect except on X86 Linux platforms.
 202 #   Assumes a very recent gcc-compatible compiler and assembler.
 203 #   (Gas prefetcht0 support was added around May 1999.)
 204 #   Empirically the code appears to still run correctly on Pentium II
 205 #   processors, though with no performance benefit.  May not run on other
 206 #   X86 processors?  In some cases this improves performance by
 207 #   15% or so.
 208 # -DUSE_3DNOW_PREFETCH causes the collector to issue AMD 3DNow style
 209 #   prefetch instructions.  Same restrictions as USE_I686_PREFETCH.
 210 #   Minimally tested.  Didn't appear to be an obvious win on a K6-2/500.
 211 # -DGC_USE_LD_WRAP in combination with the old flags listed in README.linux
 212 #   causes the collector some system and pthread calls in a more transparent
 213 #   fashion than the usual macro-based approach.  Requires GNU ld, and
 214 #   currently probably works only with Linux.
 215 # -DTHREAD_LOCAL_ALLOC defines GC_local_malloc(), GC_local_malloc_atomic()
 216 #   and GC_local_gcj_malloc().  Needed for gc_gcj.h interface.  These allocate
 217 #   in a way that usually does not involve acquisition of a global lock.
 218 #   Currently requires -DGC_LINUX_THREADS, but should be easy to port to
 219 #   other pthreads environments.  Recommended for multiprocessors.
 220 # -DPARALLEL_MARK allows the marker to run in multiple threads.  Recommended
 221 #   for multiprocessors.  Currently requires Linux on X86 or IA64, though
 222 #   support for other Posix platforms should be fairly easy to add,
 223 #   if the thread implementation is otherwise supported.
 224 # -DNO_GETENV prevents the collector from looking at environment variables.
 225 #   These may otherwise alter its configuration, or turn off GC altogether.
 226 #   I don't know of a reason to disable this, except possibly if the
 227 #   resulting process runs as a privileged user?
 228 # -DUSE_GLOBAL_ALLOC.  Win32 only.  Use GlobalAlloc instead of
 229 #   VirtualAlloc to allocate the heap.  May be needed to work around
 230 #   a Windows NT/2000 issue.  Incompatible with USE_MUNMAP.
 231 #   See README.win32 for details.
 232 # -DMAKE_BACK_GRAPH. Enable GC_PRINT_BACK_HEIGHT environment variable.
 233 #   See README.environment for details.  Experimental. Limited platform
 234 #   support.  Implies DBG_HDRS_ALL.  All allocation should be done using
 235 #   the debug interface.
 236 # -DSTUBBORN_ALLOC allows allocation of "hard to change" objects, and thus
 237 #   makes incremental collection easier.  Was enabled by default until 6.0.
 238 #   Rarely used, to my knowledge.
