tests/fp: Bump fp-test-mulAdd test timeout to 3 minutes

2024-01-12T13:23:48Z

When running the tests in slow mode with --enable-debug on a very loaded system, the fp-test-mulAdd test can take longer than 2 minutes. Bump the timeout to three minutes to make sure it passes in such situations, too. Signed-off-by: Thomas Huth Message-Id: <20231215070357.10888-16-thuth@redhat.com> Signed-off-by: Alex Bennée

configure, meson: rename targetos to host_os

2023-12-31T08:11:29Z

This variable is about the host OS, not the target. It is used a lot more since the Meson conversion, but the original sin dates back to 2003. Time to fix it. Signed-off-by: Paolo Bonzini

meson: rename config_all

tests: fp: remove unused submodules

tests/fp/berkeley-softfloat-3 and tests/fp/berkeley-testfloat-3 have been replaced by subprojects, so remove the now-unnecessary submodules. Reported-by: Michal Privoznik Signed-off-by: Paolo Bonzini

meson: subprojects: replace berkeley-{soft,test}float-3 with wraps

2023-06-06T14:30:01Z

Unlike other subprojects, these require an overlay directory to include meson rules to build the libraries. The rules are basically lifted from tests/fp/meson.build, with a few changes to create platform.h and publish a dependency. The build defines are passed through a subproject option, and posted back to users of the library via the dependency's compile_args. The only remaining user of GIT_SUBMODULES and GIT_SUBMODULES_ACTION is roms/SLOF, which is used to build pc-bios/s390-ccw. All other roms submodules are only present to satisfy the license on pre-built firmware blobs. Best reviewed with --color-moved. Reviewed-by: Daniel P. Berrangé Signed-off-by: Paolo Bonzini

tests: make fp-test less chatty when running from test suite

2023-03-01T10:31:28Z

As we like to run tests under CI with V=1 flags the softfloat tests can add up to a fair amount of extra log lines. With an update to the testfloat library we can now call fp-test with the -q flag and reduce the output to a terse one line per function tested. make check-softfloat V=1 | wc -l 759 Signed-off-by: Alex Bennée Reviewed-by: Thomas Huth Reviewed-by: Richard Henderson Message-Id: <20230228190653.1602033-5-alex.bennee@linaro.org>

enforce use of G_GNUC_PRINTF attributes

2023-01-11T09:44:34Z

We've been very gradually adding G_GNUC_PRINTF annotations to functions over years. This has been useful in detecting certain malformed printf strings, or cases where we pass user data as the printf format which is a potential security flaw. Given the inherant memory corruption danger in use of format strings vs mis-matched variadic arguments, it is worth applying G_GNUC_PRINTF to all functions using printf, even if we know they are safe. The compilers can reasonably reliably identify such places with the -Wsuggest-attribute=format / -Wmissing-format-attribute flags. Signed-off-by: Daniel P. Berrangé Message-Id: <20221219130205.687815-7-berrange@redhat.com> [-Wsuggest-attribute=format and -Wmissing-format-attribute are synonyms, only include one; disable it for testfloat. - Paolo] Signed-off-by: Paolo Bonzini

tests/fp: Do not build softfloat3 tests if TCG is disabled

2022-07-05T07:33:49Z

Technically we don't need the TCG accelerator to run the softfloat3 tests. However it is unlikely an interesting build combination. Developers using softfloat3 likely use TCG too. Similarly, developers disabling TCG shouldn't mind much about softfloat3 tests. This reduces a non-TCG build by 474 objects!

compiler.h: replace QEMU_NORETURN with G_NORETURN

2022-04-21T13:03:51Z

G_NORETURN was introduced in glib 2.68, fallback to G_GNUC_NORETURN in glib-compat. Note that this attribute must be placed before the function declaration (bringing a bit of consistency in qemu codebase usage). Signed-off-by: Marc-André Lureau Reviewed-by: Daniel P.
