* lib/libc/string: replace ffs/fls implementations with clang builtinsRobert Clausecker2023-07-032-57/+0
| | | | | | | | | | | | | | Most architectures we support (except for riscv64) have instructions to compute these functions very quickly. Replace old code with the ffs and clz builtin functions, allowing clang to generate good code for all architectures. As a consequence, toss out arm and i386 ffs() implementations.

* remove obsolete i386 MD memchr implementationEd Maste2019-09-252-62/+0
| | | | | | | | | | | | | | | bde reports (in a reply to r351700 commit mail): This uses scasb, which was last optimal on the 8086, or perhaps the original i386. On freefall, it is several times slower than the naive translation of the naive C code.

| | | | | | | | | | | | | | | | - 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.

* Renumber copyright clause 4Warner Losh2017-02-281-1/+1
| | | | | | | | | | | | Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

* Change index() and rindex() to a weak alias.Ed Schouten2012-01-052-2/+2
| | | | | | | | | | | This allows people to still write statically linked applications that call strchr() or strrchr() and have a local variable or function called index. Discussed with: bde@ Notes: svn path=/head/; revision=229571
* Merge index() and strchr() together.Ed Schouten2012-01-035-137/+7
| | | | | | | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=229368

* libc: Remove the i386 assembler version of strlen(3).Jilles Tjoelker2010-10-012-55/+1
| | | | | | | | | | | | | | | | On anything modern, the C version, which processes a word at a time, is much faster. The Intel optimization manual explicitly warns against using REP prefixes with SCAS or CMPS, which is exactly what the assembler version does. A simple test on a Phenom II showed the C version, compiled with -O2, to be about twice as fast determining the length of 100000 strings between 0 and 255 bytes long.

* Handle machine-dependent (m-d) (string) sources more automatically.Bruce Evans1997-10-161-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | The names of m-d variants are now added (manually) to MDSRCS instead of to SRCS, and the names of all machine-independent (m-i) variants that can reasonably be replaced by an m-d variant are now added (manually) to MISRCS instead of to SRCS, so that a simple substitution can be used to discard the unused m-i variants. MISRCS is potentially all m-i sources, but the substitution is too simple to be fast, so MISRCS should be kept reasonably small. libc/Makefile.inc: Do the substitution. libc/i386/string/Makefile.inc: Add to MDSRCS instead of to SRCS. Add the names of all sources in this directory, but no others. libc/string/Makefile.inc Add to MISRCS instead of to SRCS. Add the names of all sources in this directory.

* Merged with the 1996/11/12 NetBSD version:Bruce Evans1997-04-201-10/+24
| | | | | | | | | | | | | | | | | | - use a slightly less bogus copyright. This file was never contributed to Berkeley. It still claims to be copright by the Regents. - use <machine/asm.h> instead of "DEFS.h". - use RCSID($Id$) instead of explicit assembly code and messy ifdefs. The rcsid won't be put into the object file until we make RCSID() non-null. NetBSD uses a LIBC_SCCS ifdef here. We used a LIBC_RCS instead, but I want RCSID() to be controlled directly by LIBC_RCS (actually by LIB_RCS). This is the only difference with the NetBSD version. - added ifdefs to support generation of memcpy() and memmove(). The other changes are "while I'm here" to get this. - improved style of the copy backwards case. Notes: svn path=/head/; revision=25043
