the rules how to build those sources. Generate makefiles defining ${COPTS},
${CPPFLAGS}, and ${SRCS} (== template).
Note that ${CPPFLAGS} is actually dfined as _CPPFLAGS like
_CPPFLAGS.tmp___gcc_bcmp.c=-DL__gcc_bcmp
and used to generate wrapper files (e.g. tmp___gcc_bcmp.c). Otherwise it's
automagically passed to ${CC} by bsd.*.mk.
We create wrapper sources (tmp_*.[cS]) on-the-fly and compile them. For
example, __gcc_bcmp() is compiled using tmp___gcc_bcmp.c, which #define's
L__gcc_bcmp and #include's libgcc2.c.
repeatedly with different -DXXX to generate similar objects (e.g. different
type size).
- Generate a list of other CC options to build *.o.
(See my sed-fu using hold space in get_libgcc_list_objs_xflags().)
parsing dependency lines in libgcc.mk.
- Generate a list of *.o -> *.{c,S} mapping. *.S files are known as
${LIB1ASMFUNCS}. Assume other *.o files are built from *.c. This information
is needed to generated wrapper sources later.
BSD makefiles to build libgcc. The goal is to build all functions rather
than managing the set of functions in gnu/lib/libgcc/Makefile.in by hand.
Because of the complexity of the build procedure, I leave not only generated
makefiles but also intermediate, analyzed data so that people can verify that
the conversion is done correctly.
We cannot user_from_uid(3) or group_from_gid(3) unless the system
also supports pwcache_userdb(3) and pwcache_groupdb(3). The build will
use the hosts password and user database otherwise. Switch back to the
old behaviour to only the native functions if they are all present.
This fixes cross builds under Mac OS X and FreeBSD.
Fix based on problem analysis provided by Akihiko Hayashi.
in $(HAVE_BINUTILS)=="219" case.
Fixes build failures on Cygwin. (new libbfd depends on libz)
BTW, should we revive old ones under src/usr.sbin for
native dbsym(8)/mdsetimage(8) binaries which don't need libbfd?
