* MFC r314556-r314558brooks2017-03-111-4/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | r314556: Correct MDSRCS use in <arch>/string/Makefile.inc. - Remove .c files which duplicate entries in MISRCS. - Use the same, less merge conflict prone style in all cases. - Use MDSRCS for mips (.c and .S files both ended up in SRCS). - Remove pointless sparc64 Makefile.inc. - Remove uninformative foreign VCS ID entries. Reviewed by: emaste, imp, jhb MFC after: 1 week Sponsored by: DARPA, AFRL Differential Revision: https://reviews.freebsd.org/D9841 r314557: Correct an misunderstanding of MDSRCS. MDSRCS it intended to allow assembly versions of funtions with C implementations listed in MISRCS. The selection of the correct machdep_ldis?.c for a given architecture does not follow this pattern and the file should be added to SRCS directly.

| | | | | | | | | The EABI unwind info requires a .fnend for every .fnstart, and newer binutils will complain about seeing two .fnstart in a row. This change allows newer tools to compile our code. Reported by: bapt Reviewed by: imp
* Merge index() and strchr() together.ed2012-01-031-4/+3
| | | | | | | | | | | | | | | | | As I looked through the C library, I noticed the FreeBSD MIPS port has a hand-written version of index(). This is nice, if it weren't for the fact that most applications call strchr() instead. Also, on the other architectures index() and strchr() are identical, meaning we have two identical pieces of code in the C library and statically linked applications. Solve this by naming the actual file strchr.[cS] and let it use __strong_reference()/STRONG_ALIAS() to provide the index() routine. Do the same for rindex()/strrchr(). This seems to make the C libraries and static binaries slightly smaller, but this reduction in size seems negligible.
