musl/src/stdio/printf.c, branch master musl - an implementation of the standard library for Linux-based systems use restrict everywhere it's required by c99 and/or posix 2008 2012年09月07日T02:44:55+00:00 Rich Felker dalias@aerifal.cx 2012年09月07日T02:44:55+00:00 400c5e5c8307a2ebe44ef1f203f5a15669f20347 to deal with the fact that the public headers may be used with pre-c99 compilers, __restrict is used in place of restrict, and defined appropriately for any supported compiler. we also avoid the form [restrict] since older versions of gcc rejected it due to a bug in the original c99 standard, and instead use the form *restrict.

trivial optimization to printf: avoid wasted call frame 2012年08月11日T02:18:49+00:00 Rich Felker dalias@aerifal.cx 2012年08月11日T02:18:49+00:00 4c346919a9b238748de2ee85ce6d749fc3cf7059 amusingly, this cuts more than 10% off the run time of printf("a"); on the machine i tested it on. sadly the same optimization is not possible for snprintf without duplicating all the pseudo-FILE setup code, which is not worth it.
