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.

/*
* In this file we wrap QEMU FP functions to look like softfloat/testfloat's,
* so that we can use the testfloat infrastructure as-is.
*
* This file must be included directly from fp-test.c. We could compile it
* separately, but it would be tedious to add declarations for all the wrappers.

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.
