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

2022-07-05T07:33:49+00:00

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

2022-04-21T13:03:51+00:00

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.

Replace config-time define HOST_WORDS_BIGENDIAN

2022-04-06T08:50:37+00:00

Replace a config-time define with a compile time condition define (compatible with clang and gcc) that must be declared prior to its usage. This avoids having a global configure time define, but also prevents from bad usage, if the config header wasn't included before. This can help to make some code independent from qemu too. gcc supports __BYTE_ORDER__ from about 4.6 and clang from 3.2.

build: use "meson test" as the test harness

2021-12-23T09:06:19+00:00

"meson test" starting with version 0.57 is just as capable and easy to use as QEMU's own TAP driver. All existing options for "make check" work. The only required code change involves how to mark "slow" tests; they need to belong to an additional "slow" suite. The rules for .tap output are replaced by JUnit XML; GitLab is able to parse that output and present it in the CI pipeline report. Signed-off-by: Paolo Bonzini

softfloat: Move floatN_log2 to softfloat-parts.c.inc

2021-06-03T21:09:02+00:00

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.
