Use -fomit-frame-pointer for malloc.o compilation. * malloc_wrapper.cc: New file. Rename from malloc.cc. Add support for more malloc functions. Eliminate export_* calls. Just use straight malloc names. Remove unused argument from malloc lock functions. * cygwin.din: Just export straight malloc names. Add malloc_stats, malloc_trim, malloc_usable_size, mallopt, memalign, valloc. * dcrt0.cc (__cygwin_user): Eliminate export_* malloc entries. * fork.cc (fork_parent): Remove unused argument from malloc_lock argument. * malloc.cc: New file. Doug Lea's malloc v2.7.1. * cygmalloc.h: New file. * include/cygwin/version.h: Bump API_MINOR. * sync.h (muto::acquire): Use appropriate number for regparm attribute. (muto::reset): Ditto. (muto::release): Ditto. --- winsup/cygwin/cygmalloc.h | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) create mode 100644 winsup/cygwin/cygmalloc.h (limited to 'winsup/cygwin/cygmalloc.h') diff --git a/winsup/cygwin/cygmalloc.h b/winsup/cygwin/cygmalloc.h new file mode 100644 index 000000000..818d56ee3 --- /dev/null +++ b/winsup/cygwin/cygmalloc.h @@ -0,0 +1,28 @@ +/* cygmalloc.h: cygwin DLL malloc stuff + + Copyright 2002 Red Hat, Inc. + +This file is part of Cygwin. + +This software is a copyrighted work licensed under the terms of the +Cygwin license.
