musl/src/string, branch v0.9.10 musl - an implementation of the standard library for Linux-based systems Add ABI compatability aliases. 2013-04-06T06:20:28+00:00 Isaac Dunham idunham@lavabit.com 2013-04-06T06:20:28+00:00 14f0272ea1775c35801b2bc17e67ef8bb7e9742d GNU used several extensions that were incompatible with C99 and POSIX, so they used alternate names for the standard functions. The result is that we need these to run standards-conformant programs that were linked with glibc.

fix integer type issue in strverscmp 2013-02-26T06:42:11+00:00 Rich Felker dalias@aerifal.cx 2013-02-26T06:42:11+00:00 5afc74fbaa2371f30df0dc9fb7bc3afe6bd96137 lenl-lenr is not a valid expression for a signed int return value from strverscmp, since after implicit conversion from size_t to int this difference could have the wrong sign or might even be zero. using the difference for char values works since they're bounded well within the range of differences representable by int, but it does not work for size_t values.

gcc seems to be generating identical or near-identical code for both
versions, but the newer code is more expressive of what it's doing.

when strchr fails, and important piece of information already
computed, the string length, is thrown away. have strchrnul (with
namespace protection) be the underlying function so this information
can be kept, and let strchr be a wrapper for it. this also allows
strcspn to be considerably faster in the case where the match set has
a single element that's not matched.

testing with gcc 4.6.3 on x86, -Os, the old version does a duplicate
null byte check after the first loop. this is purely the compiler
being stupid, but the old code was also stupid and unintuitive in how
it expressed the check.
