[Bug target/58446] New: Support for musl libc
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58446 Bug ID: 58446 Summary: Support for musl libc Product: gcc Version: 4.8.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: gcc-bug-espfv4bhi9 at gregor dot im Created attachment 30829 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=30829&action=edit gcc/ arch-generic configuration and fixes for musl The attached patches add support for targeting the musl C library for Linux, http://musl-libc.org/ The patches are: gcc-config-musl.diff: Addition of -mmusl (akin to -mglibc, -muclibc, -mbionic) for musl libc support, as well as support for using the musl ld.so, patch to stddef.h for musl size_t support, etc. Most controversially, redefines the include dir ordering iff musl is the default target. gomp-posix.diff: Not directly related to musl, a fix to libgomp to make it properly specify required POSIX version. gcc-config-dliterate.diff: gcc_cv_target_dl_iterate_phdr=yes for musl libssp.diff: Support for libcs which provide libssp functions in libc (of which musl is the only example at present) x86.diff, arm.diff, mips.diff, powerpc.diff, aarch64.diff: ld.so specification for each target and related fixes.
