* benchtests: Add acosf function to bench-mathSunil K Pandey2021-10-291-0/+1
| | | | | | | | | | | | | | | | | | Add acosf function to bench-math and copy acosf-inputs to benchtests. Motivation for this patch is to prepare for upcoming libmvec new functions. Float and double version of libmvec functions stays together. acosf-inputs file generated from acos-inputs file using following scaling formula: f = d * (FLT_MAX/DBL_MAX) Where d is input(double) and f is output(float). If scaled float value is duplicate in new input file, nextafterf() function used to find next float value, ensuring no duplicates. Reviewed-by: H.J. Lu <hjl.tools@gmail.com>

* add workload traces for missing functions (double format)Paul Zimmermann2021-03-291-4/+5
| | | | | | | | | | This patch adds workload traces for all double format functions where such files are missing. For each function, a set of 1000 random values is generated at random using SageMath, such that the output values are meaningful (for example avoiding too large inputs for exp10 where the output would be +Inf). More details about the generated values are given at the beginning of each file. Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>

* New benchtest: pthread locksDJ Delorie2020-10-211-1/+2
| | | | | | | | Performance benchmarks for various posix locks: mutex, rwlock, spinlock, condvar, and semaphore. Each test is performed with an empty loop body or with a computationally "interesting" (i.e. difficult to optimize away, and used just to allow lock code to be "hidden" in the filler's CPU cycles).
* benchtests: Run _Float128 tests only on architectures that support itArjun Shankar2020-09-231-1/+5
| | | | | | | | | | __float128 is a non-standard name and is not available on some architectures (like aarch64 or s390x) even though they may support the standard _Float128 type. Other architectures (like armv7) don't support quad-precision floating-point operations at all. This commit replaces benchtests references to __float128 with _Float128 and runs the corresponding tests only on architectures that support it.

Reduce this to a more reasonable 40 seconds. The math tests take 10 seconds each, eventhough all they do is loop on the same input. Anything more than 1 second runtime is way overkill, so set the limit to 1 second. * benchtests/Makefile (BENCH_DURATION): Set to 1 second. * benchtests/bench-malloc-thread.c (BENCH_DURATION): Set to 10 seconds.

* Patch to require Python 3.4 or later to build glibc.Joseph Myers2018-10-291-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes Python 3.4 or later a required tool for building glibc, so allowing changes of awk, perl etc. code used in the build and test to Python code without any such changes needing makefile conditionals or to handle older Python versions. This patch makes the configure test for Python check the version and give an error if Python is missing or too old, and removes makefile conditionals that are no longer needed. It does not itself convert any code from another language to Python, and does not remove any compatibility with older Python versions from existing scripts.
