2013-05-03PowerPC: Add time vDSO supportAdhemerval Zanella5-3/+81
PowerPC kernel now provides a vDSO implementation for time syscall (commit fcb41a2030abe0eb716ef0798035ef9562097f42). This patch changes time syscall wrapper to use the vDSO when available. It also changes the default non vDSO time on PowerPC to use sysdeps/posix/time.c (since gettimeofday is a vDSO call).

2013-05-02Add yesstr and nostr to en_CA, es_AR, and es_ESCarlos O'Donell4-2/+23
We add yesstr and nostr to three more locales. We ignore the issue of capitalization of the first character in yesstr and nostr. All locales will need to be revisited to make this uniform policy change. --- 2013-05-02 Carlos O'Donell <carlos@redhat.com> [BZ #15264] * localedata/locales/en_CA (LC_MESSAGES): Define yesstr and nostr. * localedata/locales/es_AR (LC_MESSAGES): Copy es_ES. * localedata/locales/es_ES (LC_MESSAGES): Define yesstr and nostr.

2013-05-01Remove duplicate __strcmp_cgOndrej Bilka2-24/+5
The __strcmp_cg code was duplicate of of __strcmp_gc. This patch unifies these two cases into one.

2013-05-01Use __gnu_inline__ for __extern_always_inline in g++-4.2Richard Smith2-8/+14
Use the __gnu_inline__ attribute in _FORTIFY_SOURCE's __extern_always_inline macro whenever the compiler supports it. Previously this macro only included the __gnu_inline__ attribute in C++ mode for gcc >= 4.3. However, __gnu_inline__ semantics are always desired for the __extern_always_inline functions, and are available in g++ 4.2 (and some releases of g++ 4.1, and also in Clang, which claims to be g++ 4.2). This change stops g++-4.2 from emitting weak definitions for the fortify wrapper functions if they can't be inlined, and also improves Clang compatibility.

2013-04-30Allow multiple input domains to be run in the same benchmark programSiddhesh Poyarekar23-231/+204
Some math functions have distinct performance characteristics in specific domains of inputs, where some inputs return via a fast path while other inputs require multiple precision calculations, that too at different precision levels. The way to implement different domains was to have a separate source file and benchmark definition, resulting in separate programs. This clutters up the benchmark, so this change allows these domains to be consolidated into the same input file. To do this, the input file format is now enhanced to allow comments with a preceding # and directives with two # at the begining of a line. A directive that looks like: tells the benchmark generation script that what follows is a different domain of inputs. The value of the 'name' directive (in this case, foo) is used in the output. The two input domains are then executed sequentially and their results collated separately. with the above directive, there would be two lines in the result that look like: func(): .... func(foo): ...
2013-04-30Maintain runtime of each benchmark at ~10 secondsSiddhesh Poyarekar5-36/+54
The idea to run benchmarks for a constant number of iterations is problematic. While the benchmarks may run for 10 seconds on x86_64, they could run for about 30 seconds on powerpc and worse, over 3 minutes on arm. Besides that, adding a new benchmark is cumbersome since one needs to find out the number of iterations needed for a sufficient runtime. A better idea would be to run each benchmark for a specific amount of time. This patch does just that. The run time defaults to 10 seconds and it is configurable at command line: make BENCH_DURATION=5 bench

2013-04-26PowerPC: modf optimization fixAdhemerval Zanella5-0/+15
This patch fix the 3c0265394d9ffedff2b0de508602dc52e077ce5c commits by correctly setting minimum architecture for modf PPC optimization to power5+ instead of power5 (since only on power5+ round/ceil will be inline to inline assembly).

Resolves #14888. This only really manifests itself when there are no spaces between format specifiers, which is not allowed by POSIX, but is allowed by the glibc implementation.
