* tests/fp: Enable more testsAlex Bennée2021-06-032-10/+8Star
| | | | | | | | | | Fix the trivial typo in extF80_lt_quiet, and re-enable all of the floatx80 tests that are now fixed.

* softfloat: Move floatN_log2 to softfloat-parts.c.incRichard Henderson2021-06-032-0/+129
| | | | | | | | | | | | | | | | | | | | | | Rename to parts$N_log2. Though this is partly a ruse, since I do not believe the code will succeed for float128 without work. Which is ok for now, because we do not need this for more than float32 and float64. Since berkeley-testfloat-3 doesn't support log2, compare float64_log2 vs the system log2. Fix the errors for inputs near 1.0: test: 3ff00000000000b0 +0x1.00000000000b0p+0 sf: 3d2fa00000000000 +0x1.fa00000000000p-45 libm: 3d2fbd422b1bd36f +0x1.fbd422b1bd36fp-45 Error in fraction: 32170028290927 ulp test: 3feec24f6770b100 +0x1.ec24f6770b100p-1 sf: bfad3740d13c9ec0 -0x1.d3740d13c9ec0p-5 libm: bfad3740d13c9e98 -0x1.d3740d13c9e98p-5 Error in fraction: 40 ulp Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
* tests/fp/fp-test: Reverse order of floatx80 precision testsRichard Henderson2021-06-031-4/+4
| | | | | | | | | | Many qemu softfloat will check floatx80_rounding_precision even when berkeley testfloat will not. So begin with floatx80_precision_x, so that's the one we use when !FUNC_EFF_ROUNDINGPRECISION.

* meson: rename included C source files to .c.incPaolo Bonzini2020-08-212-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | 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.
