1 # This is the original manually generated Makefile. It may still be used
2 # to build the collector.
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.
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.
18 AS_ABI_FLAG=$(ABI_FLAG)
19 # ABI flag for assembler. On HP/UX this is +A64 for 64 bit
25 # The above doesn't work with gas, which doesn't run cpp.
26 # Define AS as `gcc -c -x assembler-with-cpp' instead.
28 # Redefining srcdir allows object code for the nonPCR version of the collector
29 # to be generated in different directories.
33 # Atomic_ops installation directory. If this doesn't exist, we create
34 # it from the included libatomic_ops distribution.

41 # To build the parallel collector on Linux, add to the above:
42 # -DGC_LINUX_THREADS -DPARALLEL_MARK -DTHREAD_LOCAL_ALLOC
43 # To build the thread-capable preload library that intercepts
44 # malloc, add -DGC_USE_DLOPEN_WRAP -DREDIRECT_MALLOC=GC_malloc -fpic
45 # To build the parallel collector in a static library on HP/UX,
47 # -DGC_HPUX_THREADS -DTHREAD_LOCAL_ALLOC -D_POSIX_C_SOURCE=199506L -mt
48 # FIXME: PARALLEL_MARK currently broken on HP/UX.
49 # To build the thread-safe collector on Tru64, add to the above:
50 # -pthread -DGC_OSF1_THREADS
52 # HOSTCC and HOSTCFLAGS are used to build executables that will be run as
53 # part of the build process, i.e. on the build machine. These will usually
54 # be the same as CC and CFLAGS, except in a cross-compilation environment.
55 # Note that HOSTCFLAGS should include any -D flags that affect thread support.
59 # For dynamic library builds, it may be necessary to add flags to generate
60 # PIC code, e.g. -fPIC on Linux.
62 # Setjmp_test may yield overly optimistic results when compiled
63 # without optimization.
65 # These define arguments influence the collector configuration:
66 # -DFIND_LEAK causes GC_find_leak to be initially set.
67 # This causes the collector to assume that all inaccessible
68 # objects should have been explicitly deallocated, and reports exceptions.
69 # Finalization and the test program are not usable in this mode.
71 # IMPORTANT: Any of the _THREADS options must normally also be defined in
72 # the client before including gc.h. This redefines thread primitives to
73 # invoke the GC_ versions instead. Alternatively, linker-based symbol
74 # interception can be used on a few platforms.
75 # -DGC_THREADS should set the appropriate one of the below macros,
76 # except -DGC_WIN32_PTHREADS, which must be set explicitly.
77 # -DGC_SOLARIS_PTHREADS enables support for Solaris pthreads.
78 # (Clients should also define GC_SOLARIS_THREADS and then include
79 # gc.h before performing thr_ or dl* or GC_ operations.)
80 # Must also define -D_REENTRANT.
81 # -DGC_IRIX_THREADS enables support for Irix pthreads. See README.irix.
82 # -DGC_HPUX_THREADS enables support for HP/UX 11 pthreads.
83 # Also requires -D_REENTRANT or -D_POSIX_C_SOURCE=199506L. See README.hp.
84 # -DGC_LINUX_THREADS enables support for Xavier Leroy's Linux threads
85 # or NPTL threads. See README.linux. -D_REENTRANT may also be required.
86 # -DGC_OSF1_THREADS enables support for Tru64 pthreads.
87 # -DGC_FREEBSD_THREADS enables support for FreeBSD pthreads.
88 # Appeared to run into some underlying thread problems.
89 # -DGC_DARWIN_THREADS enables support for Mac OS X pthreads.
90 # -DGC_AIX_THREADS enables support for IBM AIX threads.
91 # -DGC_DGUX386_THREADS enables support for DB/UX on I386 threads.
92 # See README.DGUX386. (Probably has not been tested recently.)
93 # -DGC_WIN32_THREADS enables support for win32 threads. That makes sense
94 # for this Makefile only under Cygwin.
95 # -DGC_WIN32_PTHREADS enables support for Ming32 pthreads. This cannot be
96 # enabled automatically by GC_THREADS, which would assume Win32 native
98 # -DPTW32_STATIC_LIB causes the static version of the Mingw pthreads library
99 # to be used. Requires -DGC_WIN32_PTHREADS.
101 # -DALL_INTERIOR_POINTERS allows all pointers to the interior
102 # of objects to be recognized. (See gc_priv.h for consequences.)
103 # Alternatively, GC_all_interior_pointers can be set at process
104 # initialization time.
105 # -DSMALL_CONFIG tries to tune the collector for small heap sizes,
106 # usually causing it to use less space in such situations.
107 # Incremental collection no longer works in this case.
108 # -DLARGE_CONFIG tunes the collector for unusually large heaps.
109 # Necessary for heaps larger than about 500 MB on most machines.
110 # Recommended for heaps larger than about 64 MB.
111 # -DDONT_ADD_BYTE_AT_END is meaningful only with -DALL_INTERIOR_POINTERS or
112 # GC_all_interior_pointers = 1. Normally -DALL_INTERIOR_POINTERS
113 # causes all objects to be padded so that pointers just past the end of
114 # an object can be recognized. This can be expensive. (The padding
115 # is normally more than one byte due to alignment constraints.)
116 # -DDONT_ADD_BYTE_AT_END disables the padding.
117 # -DNO_EXECUTE_PERMISSION may cause some or all of the heap to not
118 # have execute permission, i.e. it may be impossible to execute
119 # code from the heap. Currently this only affects the incremental
120 # collector on UNIX machines. It may greatly improve its performance,
121 # since this may avoid some expensive cache synchronization.
122 # -DGC_NO_OPERATOR_NEW_ARRAY declares that the C++ compiler does not support
123 # the new syntax "operator new[]" for allocating and deleting arrays.
124 # See gc_cpp.h for details. No effect on the C part of the collector.
125 # This is defined implicitly in a few environments. Must also be defined
126 # by clients that use gc_cpp.h.
127 # -DREDIRECT_MALLOC=X causes malloc to be defined as alias for X.
128 # Unless the following macros are defined, realloc is also redirected
129 # to GC_realloc, and free is redirected to GC_free.
130 # Calloc and strdup are redefined in terms of the new malloc. X should
131 # be either GC_malloc or GC_malloc_uncollectable, or
132 # GC_debug_malloc_replacement. (The latter invokes GC_debug_malloc
133 # with dummy source location information, but still results in
134 # properly remembered call stacks on Linux/X86 and Solaris/SPARC.
135 # It requires that the following two macros also be used.)
136 # The former is occasionally useful for working around leaks in code
137 # you don't want to (or can't) look at. It may not work for
138 # existing code, but it often does. Neither works on all platforms,
139 # since some ports use malloc or calloc to obtain system memory.
140 # (Probably works for UNIX, and win32.) If you build with DBG_HDRS_ALL,
141 # you should only use GC_debug_malloc_replacement as a malloc
143 # -DREDIRECT_REALLOC=X causes GC_realloc to be redirected to X.
144 # The canonical use is -DREDIRECT_REALLOC=GC_debug_realloc_replacement,
145 # together with -DREDIRECT_MALLOC=GC_debug_malloc_replacement to
146 # generate leak reports with call stacks for both malloc and realloc.
147 # This also requires the following:
148 # -DREDIRECT_FREE=X causes free to be redirected to X. The
149 # canonical use is -DREDIRECT_FREE=GC_debug_free.
150 # -DIGNORE_FREE turns calls to free into a noop. Only useful with
152 # -DNO_DEBUGGING removes GC_dump and the debugging routines it calls.
153 # Reduces code size slightly at the expense of debuggability.
154 # -DJAVA_FINALIZATION makes it somewhat safer to finalize objects out of
155 # order by specifying a nonstandard finalization mark procedure (see
156 # finalize.c). Objects reachable from finalizable objects will be marked
157 # in a separate postpass, and hence their memory won't be reclaimed.
158 # Not recommended unless you are implementing a language that specifies
159 # these semantics. Since 5.0, determines only the initial value
160 # of GC_java_finalization variable.
161 # -DFINALIZE_ON_DEMAND causes finalizers to be run only in response
162 # to explicit GC_invoke_finalizers() calls.
163 # In 5.0 this became runtime adjustable, and this only determines the
164 # initial value of GC_finalize_on_demand.
165 # -DATOMIC_UNCOLLECTABLE includes code for GC_malloc_atomic_uncollectable.
166 # This is useful if either the vendor malloc implementation is poor,
167 # or if REDIRECT_MALLOC is used.
168 # -DMARK_BIT_PER_GRANULE requests that a mark bit (or often byte)
169 # be allocated for each allocation granule, as opposed to each object.
170 # This often improves speed, possibly at some cost in space and/or
171 # cache footprint. Normally it is best to let this decision be
172 # made automatically depending on platform.
173 # -DMARK_BIT_PER_OBJ requests that a mark bit be allocated for each
174 # object instead of allocation granule. The opposiet of
175 # MARK_BIT_PER_GRANULE.
176 # -DHBLKSIZE=ddd, where ddd is a power of 2 between 512 and 16384, explicitly
177 # sets the heap block size. Each heap block is devoted to a single size and
178 # kind of object. For the incremental collector it makes sense to match
179 # the most likely page size. Otherwise large values result in more
180 # fragmentation, but generally better performance for large heaps.
181 # -DUSE_MMAP use MMAP instead of sbrk to get new memory.
182 # Works for Solaris and Irix.
183 # -DUSE_MUNMAP causes memory to be returned to the OS under the right
184 # circumstances. This currently disables VM-based incremental collection.
185 # This is currently experimental, and works only under some Unix,
186 # Linux and Windows versions. Requires -DUSE_MMAP, even under Windows,
187 # where USE_MMAP doesn't do anything.
188 # -DMMAP_STACKS (for Solaris threads) Use mmap from /dev/zero rather than
189 # GC_scratch_alloc() to get stack memory.
190 # -DPRINT_BLACK_LIST Whenever a black list entry is added, i.e. whenever
191 # the garbage collector detects a value that looks almost, but not quite,
192 # like a pointer, print both the address containing the value, and the
193 # value of the near-bogus-pointer. Can be used to identifiy regions of
194 # memory that are likely to contribute misidentified pointers.
195 # -DKEEP_BACK_PTRS Add code to save back pointers in debugging headers
196 # for objects allocated with the debugging allocator. If all objects
197 # through GC_MALLOC with GC_DEBUG defined, this allows the client
198 # to determine how particular or randomly chosen objects are reachable
199 # for debugging/profiling purposes. The gc_backptr.h interface is
200 # implemented only if this is defined.
201 # -DGC_ASSERTIONS Enable some internal GC assertion checking. Currently
202 # this facility is only used in a few places. It is intended primarily
203 # for debugging of the garbage collector itself, but could also
204 # -DDBG_HDRS_ALL Make sure that all objects have debug headers. Increases
205 # the reliability (from 99.9999% to 100% mod. bugs) of some of the debugging
206 # code (especially KEEP_BACK_PTRS). Makes -DSHORT_DBG_HDRS possible.
207 # Assumes that all client allocation is done through debugging
209 # -DSHORT_DBG_HDRS Assume that all objects have debug headers. Shorten
210 # the headers to minimize object size, at the expense of checking for
211 # writes past the end of an object. This is intended for environments
212 # in which most client code is written in a "safe" language, such as
213 # Scheme or Java. Assumes that all client allocation is done using
214 # the GC_debug_ functions, or through the macros that expand to these,
215 # or by redirecting malloc to GC_debug_malloc_replacement.
216 # (Also eliminates the field for the requested object size.)
217 # -DSAVE_CALL_COUNT=<n> Set the number of call frames saved with objects
218 # allocated through the debugging interface. Affects the amount of
219 # information generated in leak reports. Only matters on platforms
220 # on which we can quickly generate call stacks, currently Linux/(X86 & SPARC)
221 # and Solaris/SPARC and platforms that provide execinfo.h.
222 # Default is zero. On X86, client
223 # code should NOT be compiled with -fomit-frame-pointer.
224 # -DSAVE_CALL_NARGS=<n> Set the number of functions arguments to be
225 # saved with each call frame. Default is zero. Ignored if we
226 # don't know how to retrieve arguments on the platform.
227 # -DCHECKSUMS reports on erroneously clear dirty bits, and unexpectedly
228 # altered stubborn objects, at substantial performance cost.
229 # Use only for debugging of the incremental collector.
230 # -DGC_GCJ_SUPPORT includes support for gcj (and possibly other systems
231 # that include a pointer to a type descriptor in each allocated object).
232 # Building this way requires an ANSI C compiler.
233 # -DUSE_I686_PREFETCH causes the collector to issue Pentium III style
234 # prefetch instructions. No effect except on X86 Linux platforms.
235 # Assumes a very recent gcc-compatible compiler and assembler.
236 # (Gas prefetcht0 support was added around May 1999.)
237 # Empirically the code appears to still run correctly on Pentium II
238 # processors, though with no performance benefit. May not run on other
239 # X86 processors? In some cases this improves performance by
241 # -DUSE_3DNOW_PREFETCH causes the collector to issue AMD 3DNow style
242 # prefetch instructions. Same restrictions as USE_I686_PREFETCH.
243 # Minimally tested. Didn't appear to be an obvious win on a K6-2/500.
244 # -DUSE_PPC_PREFETCH causes the collector to issue PowerPC style
245 # prefetch instructions. No effect except on PowerPC OS X platforms.
246 # Performance impact untested.
247 # -DGC_USE_LD_WRAP in combination with the old flags listed in README.linux
248 # causes the collector some system and pthread calls in a more transparent
249 # fashion than the usual macro-based approach. Requires GNU ld, and
250 # currently probably works only with Linux.
251 # -DGC_USE_DLOPEN_WRAP causes the collector to redefine malloc and intercepted
252 # pthread routines with their real names, and causes it to use dlopen
253 # and dlsym to refer to the original versions. This makes it possible to
254 # build an LD_PRELOADable malloc replacement library.
255 # -DTHREAD_LOCAL_ALLOC defines GC_malloc(), GC_malloc_atomic()
256 # and GC_gcj_malloc() to use a per-thread set of free-lists.
257 # These then allocate in a way that usually does not involve
258 # acquisition of a global lock. Currently supported only on platforms
259 # such as Linux that use pthread_support.c. Recommended for multiprocessors.
260 # Requires explicit GC_INIT() call, unless REDIRECT_MALLOC is
261 # defined and GC_malloc is used first.
262 # -DUSE_COMPILER_TLS causes thread local allocation to use compiler-supported
263 # "__thread" thread-local variables. This is the default in HP/UX. It
264 # may help performance on recent Linux installations. (It failed for
265 # me on RedHat 8, but appears to work on RedHat 9.)
266 # -DPARALLEL_MARK allows the marker to run in multiple threads. Recommended
267 # for multiprocessors. Currently requires Linux on X86 or IA64, though
268 # support for other Posix platforms should be fairly easy to add,
269 # if the thread implementation is otherwise supported.
270 # -DNO_GETENV prevents the collector from looking at environment variables.
271 # These may otherwise alter its configuration, or turn off GC altogether.
272 # I don't know of a reason to disable this, except possibly if the
273 # resulting process runs as a privileged user?
274 # -DUSE_GLOBAL_ALLOC. Win32 only. Use GlobalAlloc instead of
275 # VirtualAlloc to allocate the heap. May be needed to work around
276 # a Windows NT/2000 issue. Incompatible with USE_MUNMAP.
277 # See README.win32 for details.
278 # -DMAKE_BACK_GRAPH. Enable GC_PRINT_BACK_HEIGHT environment variable.
279 # See README.environment for details. Experimental. Limited platform
280 # support. Implies DBG_HDRS_ALL. All allocation should be done using
281 # the debug interface.
282 # -DSTUBBORN_ALLOC allows allocation of "hard to change" objects, and thus
283 # makes incremental collection easier. Was enabled by default until 6.0.
284 # Rarely used, to my knowledge.
285 # -DHANDLE_FORK attempts to make GC_malloc() work in a child process fork()ed
286 # from a multithreaded parent. Currently only supported by pthread_support.c.
287 # (Similar code should work on Solaris or Irix, but it hasn't been tried.)
288 # -DTEST_WITH_SYSTEM_MALLOC causes gctest to allocate (and leak) large chunks
289 # of memory with the standard system malloc. This will cause the root
290 # set and collected heap to grow significantly if malloced memory is
291 # somehow getting traced by the collector. This has no impact on the
292 # generated library; it only affects the test.
293 # -DNO_INCREMENTAL cases the gctest program to not invoke the incremental
294 # collector. This has no impact on the generated library, only on the
295 # test program. (This is often useful for debugging failures unrelated
296 # to incremental GC.)
297 # -DPOINTER_MASK=0x... causes candidate pointers to be ANDed with the
298 # given mask before being considered. If either this or the following
299 # macro is defined, it will be assumed that all pointers stored in
300 # the heap need to be processed this way. Stack and register pointers
301 # will be considered both with and without processing.
302 # These macros are normally needed only to support systems that use
303 # high-order pointer tags. EXPERIMENTAL.
304 # -DPOINTER_SHIFT=n causes the collector to left shift candidate pointers
305 # by the indicated amount before trying to interpret them. Applied
306 # after POINTER_MASK. EXPERIMENTAL. See also the preceding macro.
307 # -DENABLE_TRACE enables the GC_TRACE=addr environment setting to do its
308 # job. By default this is not supported in order to keep the marker as fast
310 # -DDARWIN_DONT_PARSE_STACK Causes the Darwin port to discover thread
311 # stack bounds in the same way as other pthread ports, without trying to
312 # walk the frames onthe stack. This is recommended only as a fallback
313 # for applications that don't support proper stack unwinding.
314 # -DUSE_PROC_FOR_LIBRARIES Causes the Linux collector to treat writable
315 # memory mappings (as reported by /proc) as roots, if it doesn't have
316 # otherinformation about them. It no longer traverses dynamic loader
317 # data structures to find dynamic library static data. This may be
318 # required for applications that store pointers in mmapped segments without
319 # informaing the collector. But it typically performs poorly, especially
320 # since it will scan inactive but cached NPTL thread stacks completely.
321 # -DNO_PROC_STAT Causes the collector to avoid relying on Linux'
