2023-01-15Delete ffs and strrchr prototypes.Flavio Cruz
We use __builtin_ffs instead of ffs. strrchr is not used. Also removed the commented out memset implementation since it is implemented in arch-specific code. Message-Id: <Y8NOXbVzhBJknR29@mercury.tail36e24.ts.net>

* Makefile.am (clib_routines): Remove memcmp, memcpy, memmove, strchr, strstr and strsep. * kern/strings.c (memset): Comment out. (strchr, strsep, strstr): New functions.

2012-01-22Fix build on 64bit hostSamuel Thibault
When stealing the memset function from the 32bit host libc on a 64bit host system, glibc tends to bring unwanted references to _Unwind_Resume, __gcc_personality_v0, etc. So let's stop stealing memset. * kern/strings.c (memset): New function. * Makefile.am (clib_routines): Remove memset.
