The HP_TIMING_AVAIL and HP_SMALL_TIMING_AVAIL are removed and HP_TIMING_INLINE is used instead to check for hp-timing avaliability. For alpha, which only defines HP_SMALL_TIMING_AVAIL, the HP_TIMING_INLINE is set iff for IS_IN(rtld). Checked on aarch64-linux-gnu, x86_64-linux-gnu, and i686-linux-gnu. I also checked the builds for all afected ABIs. * benchtests/bench-timing.h: Replace HP_TIMING_AVAIL with HP_TIMING_INLINE. * nptl/descr.h: Likewise. * elf/rtld.c (RLTD_TIMING_DECLARE, RTLD_TIMING_NOW, RTLD_TIMING_DIFF, RTLD_TIMING_ACCUM_NT, RTLD_TIMING_SET): Define. (dl_start_final_info, _dl_start_final, dl_main, print_statistics): Abstract hp-timing usage with RTLD_* macros. * sysdeps/alpha/hp-timing.h (HP_TIMING_INLINE): Define iff IS_IN(rtld). (HP_TIMING_AVAIL, HP_SMALL_TIMING_AVAIL): Remove. * sysdeps/generic/hp-timing.h (HP_TIMING_AVAIL, HP_SMALL_TIMING_AVAIL, HP_TIMING_NONAVAIL): Likewise. * sysdeps/ia64/hp-timing.h (HP_TIMING_AVAIL, HP_SMALL_TIMING_AVAIL): Likewise. * sysdeps/powerpc/powerpc32/power4/hp-timing.h (HP_TIMING_AVAIL, HP_SMALL_TIMING_AVAIL): Likewise. * sysdeps/powerpc/powerpc64/hp-timing.h (HP_TIMING_AVAIL, HP_SMALL_TIMING_AVAIL): Likewise. * sysdeps/sparc/sparc32/sparcv9/hp-timing.h (HP_TIMING_AVAIL, HP_SMALL_TIMING_AVAIL): Likewise. * sysdeps/sparc/sparc64/hp-timing.h (HP_TIMING_AVAIL, HP_SMALL_TIMING_AVAIL): Likewise. * sysdeps/x86/hp-timing.h (HP_TIMING_AVAIL, HP_SMALL_TIMING_AVAIL): Likewise. * sysdeps/generic/hp-timing-common.h: Update comment with HP_TIMING_AVAIL removal. --- benchtests/bench-timing.h | 2 +- elf/rtld.c | 231 +++++++++---------- nptl/descr.h | 2 +- sysdeps/alpha/hp-timing.h | 18 +- sysdeps/generic/hp-timing-common.h | 2 - sysdeps/generic/hp-timing.h | 5 - sysdeps/ia64/hp-timing.h | 4 - sysdeps/powerpc/powerpc32/power4/hp-timing.h | 4 - sysdeps/powerpc/powerpc64/hp-timing.h | 4 - sysdeps/sparc/sparc32/sparcv9/hp-timing.h | 2 - sysdeps/sparc/sparc64/hp-timing.h | 2 - sysdeps/x86/hp-timing.h | 4 - 12 files changed, 117 insertions(+), 163 deletions(-) diff --git a/benchtests/bench-timing.h b/benchtests/bench-timing.h index 41b7324527..93fe379f99 100644 --- a/benchtests/bench-timing.h +++ b/benchtests/bench-timing.h @@ -21,7 +21,7 @@ #include #include -#if HP_TIMING_AVAIL && !defined USE_CLOCK_GETTIME +#if HP_TIMING_INLINE && !defined USE_CLOCK_GETTIME # define GL(x) _##x # define GLRO(x) _##x typedef hp_timing_t timing_t; diff --git a/elf/rtld.c b/elf/rtld.c index 34c9016da1..d4089de735 100644 --- a/elf/rtld.c +++ b/elf/rtld.c @@ -46,6 +46,21 @@ #include +#if HP_TIMING_INLINE +# define RLTD_TIMING_DECLARE(var, classifier,...) \ + classifier hp_timing_t var __VA_ARGS__ +# define RTLD_TIMING_NOW(var) HP_TIMING_NOW(var) +# define RTLD_TIMING_DIFF(diff, start, end) HP_TIMING_DIFF(diff, start, end) +# define RTLD_TIMING_ACCUM_NT(sum, diff) HP_TIMING_ACCUM_NT(sum, diff) +# define RTLD_TIMING_SET(var, value) (var) = (value) +#else +# define RLTD_TIMING_DECLARE(var, classifier...) +# define RTLD_TIMING_NOW(var) +# define RTLD_TIMING_DIFF(diff, start, end) +# define RTLD_TIMING_ACCUM_NT(sum, diff) +# define RTLD_TIMING_SET(var, value) +#endif + /* Avoid PLT use for our local calls at startup. */ extern __typeof (__mempcpy) __mempcpy attribute_hidden; @@ -303,11 +318,9 @@ static struct libname_list _dl_rtld_libname; static struct libname_list _dl_rtld_libname2; /* Variable for statistics. */ -#ifndef HP_TIMING_NONAVAIL -static hp_timing_t relocate_time; -static hp_timing_t load_time attribute_relro; -static hp_timing_t start_time attribute_relro; -#endif +RLTD_TIMING_DECLARE (relocate_time, static); +RLTD_TIMING_DECLARE (load_time, static, attribute_relro); +RLTD_TIMING_DECLARE (start_time, static, attribute_relro); /* Additional definitions needed by TLS initialization. */ #ifdef TLS_INIT_HELPER @@ -335,9 +348,7 @@ static ElfW(Addr) _dl_start_final (void *arg); struct dl_start_final_info { struct link_map l; -#if !defined HP_TIMING_NONAVAIL && HP_TIMING_INLINE - hp_timing_t start_time; -#endif + RLTD_TIMING_DECLARE (start_time,); }; static ElfW(Addr) _dl_start_final (void *arg, struct dl_start_final_info *info); @@ -371,16 +382,10 @@ _dl_start_final (void *arg, struct dl_start_final_info *info) { ElfW(Addr) start_addr; - if (HP_SMALL_TIMING_AVAIL) - { - /* If it hasn't happen yet record the startup time. */ - if (!
