From 26832d045f46e68b79277916edbad7512d253704 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Fri, 13 Apr 2012 03:59:36 -0400 Subject: use macros instead of inline functions in shgetc.h at -Os optimization level, gcc refuses to inline these functions even though the inlined code would roughly the same size as the function call, and much faster. the easy solution is to make them into macros. --- src/internal/shgetc.h | 24 ++++-------------------- 1 file changed, 4 insertions(+), 20 deletions(-) (limited to 'src/internal') diff --git a/src/internal/shgetc.h b/src/internal/shgetc.h index 3434cdaa..0543cb0d 100644 --- a/src/internal/shgetc.h +++ b/src/internal/shgetc.h @@ -3,23 +3,7 @@ void __shlim(FILE *, off_t); int __shgetc(FILE *); -static inline off_t shcnt(FILE *f) -{ - return f->shcnt + (f->rpos - f->rend); -} - -static inline void shlim(FILE *f, off_t lim) -{ - __shlim(f, lim); -} - -static inline int shgetc(FILE *f) -{ - if (f->rpos < f->shend) return *f->rpos++; - return __shgetc(f); -} - -static inline void shunget(FILE *f) -{ - if (f->rend) f->rpos--; -} +#define shcnt(f) ((f)->shcnt + ((f)->rpos - (f)->rend)) +#define shlim(f, lim) __shlim((f), (lim)) +#define shgetc(f) (((f)->rpos < (f)->shend) ? *(f)->rpos++ : __shgetc(f)) +#define shunget(f) ((f)->rend ?
