builtin-attrs.def (__builtin_printf_unlocked, [...]): Mark with the __printf__ attribute.
* builtin-attrs.def (__builtin_printf_unlocked,
__builtin_fprintf_unlocked, printf_unlocked, fprintf_unlocked):
Mark with the __printf__ attribute.
* builtins.c (expand_builtin_fputs): Add an `unlocked' parameter
and set the replacement function depending on it.
(expand_builtin): Skip BUILT_IN_*_UNLOCKED when not optimizing.
Handle BUILT_IN_*_UNLOCKED when optimizing.
* builtins.def (DEF_EXT_FALLBACK_BUILTIN,
DEF_EXT_FRONT_END_LIB_BUILTIN): New macros.
Declare the "unlocked" stdio functions.
* c-common.c (c_expand_builtin_printf, c_expand_builtin_fprintf):
Add an `unlocked' parameter and set the replacement function
depending on it.
(c_expand_builtin): Handle BUILT_IN_PRINTF_UNLOCKED and
BUILT_IN_FPRINTF_UNLOCKED.
* doc/extend.texi (printf_unlocked, fprintf_unlocked,
fputs_unlocked): Document.
testsuite:
