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

tests/fp: add fp-bench 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).
