testing: don't nest build for fp-test

2020-01-09T11:41:29+00:00

Re-calling the main make is counter-productive and really messes up with parallel builds. Just ensure we have built the pre-requisites before we build the fp-test bits. If the user builds manually just complain if the parent build hasn't got the bits we need. Signed-off-by: Alex Bennée Reviewed-by: Emilio G. Cota

tests/fp/Makefile: do not use gcc-only -W flags

tests/fp: add fp-bench

2018-12-17T08:25:25+00:00

These microbenchmarks will allow us to measure the performance impact of FP emulation optimizations. Note that we can measure both directly the impact on the softfloat functions (with "-t soft"), or the impact on an emulated workload (call with "-t host" and run under qemu user-mode).

fp-test: pick TARGET_ARM to get its specialization

This gets rid of the muladd errors due to not raising the invalid flag. - Before: Errors found in f64_mulAdd, rounding near_even, tininess before rounding: +000.0000000000000 +7FF.0000000000000 +7FF.FFFFFFFFFFFFF => +7FF.FFFFFFFFFFFFF ..... expected -7FF.FFFFFFFFFFFFF v....

tests/fp/fp-test: add floating point tests

2018-10-05T17:57:41+00:00

By leveraging berkeley's softfloat and testfloat. With this we get decent coverage of softfloat.c: $ ./fp-test -r even: 67.22% coverage $ ./fp-test -r all: 73.11% coverage Note that we do not yet test parts of softfloat.c that aren't in the original softfloat library, namely: - denormal inputs - *_to_int16/uint16 conversions - scalbn for fixed point - muladd variants - min/max - exp2 - log2 - float*_compare (except float16_compare) Signed-off-by: Emilio G.
