* tests/fp/fp-test: Replace the word 'blacklist'Philippe Mathieu-Daudé2021-03-091-4/+4

* meson: adjust timeouts for some slower testsPaolo Bonzini2021-03-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Adjust the timeouts for the benchmarks (Meson 0.57 allows 0 to mean infinite) and for the longest running tests. These are the times that I measured and the corresponding timeouts. For generic qtests, the target that reported the longest runtime is included. unit tests: test-crypto-tlscredsx509 13.15s 45s test-crypto-tlssession 14.12s 45s qtests: qos-test 21.26s 60s (i386) ahci-test 22.18s 60s pxe-test 26.51s 60s boot-serial-test 28.02s 60s (sparc) prom-env-test 28.86s 60s bios-tables-test 50.17s 120s (aarch64) test-hmp 57.15s 120s (aarch64) npcm7xx_pwm-test 71.27s 150s migration-test 97.09s 150s (aarch64) qom-test 139.20s 240s (aarch64) Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* tests/fp: Do not emit implicit-fallthrough warnings in the softfloat testsThomas Huth2020-12-181-0/+2
| | | | | | | | | | | The softfloat tests are external repositories, so we do not care about implicit fallthrough warnings in this code.

* do not use colons in test namesPaolo Bonzini2020-10-221-3/+3
| | | | | | | Starting with meson 0.56, colons are used to separate the subproject name from the test name. Use dash or slash depending on what looks nicer. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

* 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.

* testing: don't nest build for fp-testAlex Bennée2020-01-091-8/+6Star
| | | | | | | | | | 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>
* softfloat: Support float_round_to_odd more placesRichard Henderson2019-02-261-9/+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.
