* benchtests: Better libmvec integrationSiddhesh Poyarekar2022-04-291-15/+17
| | | | | | | | Improve libmvec benchmark integration so that in future other architectures may be able to run their libmvec benchmarks as well. This now allows libmvec benchmarks to be run with `make BENCHSET=bench-math`. Signed-off-by: Siddhesh Poyarekar <siddhesh@sourceware.org>
* benchtests: Add UNSUPPORTED benchmark statusSiddhesh Poyarekar2022-04-291-5/+18
| | | | | | | | | | | | The libmvec benchmarks print a message indicating that a certain CPU feature is unsupported and exit prematurelyi, which breaks the JSON in bench.out. Handle this more elegantly in the bench makefile target by adding support for an UNSUPPORTED exit status (77) so that bench.out continues to have output for valid tests.

* benchtests: Add pthread-mutex-locks benchWangyang Guo2022-04-271-0/+2
| | | | | | | | | | | | | | | | | | | | Benchmark for testing pthread mutex locks performance with different threads and critical sections. The test configuration consists of 3 parts: 1. thread number 2. critical-section length 3. non-critical-section length Thread number starts from 1 and increased by 2x until num of CPU cores (nprocs). An additional over-saturation case (1.25 * nprocs) is also included. Critical-section is represented by a loop of shared do_filler(), length can be determined by the loop iters. Non-critical-section is similiar to the critical-section, except it's based on non-shared do_filler(). Currently, adaptive pthread_mutex lock is tested.

* 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>

* New benchtest: pthread locksDJ Delorie2020-10-211-1/+2
| | | | | | | | Performance benchmarks for various posix locks: mutex, rwlock, spinlock, condvar, and semaphore.

* 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.
