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.

meson: rename included C source files to .c.inc With Makefiles that have automatically generated dependencies, you generated includes are set as dependencies of the Makefile, so that they are built before everything else and they are available when first building the .c files. Alternatively you can use a fine-grained dependency, e.g. target/arm/translate.o: target/arm/decode-neon-shared.inc.c With Meson you have only one choice and it is a third option, namely "build at the beginning of the corresponding target"; the way you express it is to list the includes in the sources of that target. The problem is that Meson decides if something is a source vs. a generated include by looking at the extension: '.c', '.cc', '.m', '.C' are sources, while everything else is considered an include---including '.inc.c'. Use '.c.inc' to avoid this, as it is consistent with our other convention of using '.rst.inc' for included reStructuredText files. The editorconfig file is adjusted.
