- Subject: [PATCH]: add builtin stpncpy, strcasecmp and strncasecmp
This patch adds three more builtins: stpncpy, strcasecmp and
strncasecmp.
Bootstrapped on x86_64-unknown-linux-gnu, no regressions.
Okay for mainline?
Thanks,

* builtins.def (BUILT_IN_STPNCPY, BUILT_IN_STRCASECMP,
BUILT_IN_STRNCASECMP): New.
testsuite:
* gcc.dg/nonnull-3.c: Also test __builtin_stpncpy,
__builtin_strcasecmp and __builtin_strncasecmp.
