2020-09-30meson: clean up build_by_defaultPaolo Bonzini1-2/+0
Build all executables by default except for the known-broken ones. This also allows running qemu-iotests without manually building socket_scm_helper. Reported-by: Max Reitz <mreitz@redhat.com> Tested-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2020-08-21meson: rename included C source files to .c.incPaolo Bonzini2-1/+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.

2020-05-19softfloat: Change tininess_before_rounding to boolRichard Henderson1-1/+1
Slightly tidies the usage within softfloat.c and the representation in float_status. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2020-01-09testing: don't nest build for fp-testAlex Bennée1-8/+6
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 <alex.bennee@linaro.org> Reviewed-by: Emilio G. Cota <cota@braap.org>
2019-02-26softfloat: Support float_round_to_odd more placesRichard Henderson1-9/+34
Previously this was only supported for roundAndPackFloat64. New support in round_canonical, round_to_int, float128_round_to_int, roundAndPackFloat32, roundAndPackInt32, roundAndPackInt64, roundAndPackUint64. This does not include any of the floatx80 routines, as we do not have users for that rounding mode there.

2019-01-22tests/fp/platform.h: include config-host.hEmilio G. Cota1-0/+1
We get HOST_WORDS_BIGENDIAN from config-host.h, but the include is missing. Fix it. This fixes `make check-softfloat' on big endian hosts. Reported-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Emilio G. Cota <cota@braap.org> Signed-off-by: Alex Bennée <alex.bennee@linaro.org>

2019-01-22fp-bench: remove wrong exponent raise in fill_randomEmilio G. Cota1-4/+0
At this point random_ops[] only contains normals, so there's no need to do anything to them. In fact, raising the exponent here can make the output !normal, which is precisely what the comment says we want to avoid. Signed-off-by: Emilio G.

Clean up includes so that osdep.h is included first and headers which it implies are not included manually.

2018-12-17tests/fp: add fp-benchEmilio G. Cota3-1/+635
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).
