2022-07-05tests/fp: Do not build softfloat3 tests if TCG is disabledPhilippe Mathieu-Daudé
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!

2022-04-21compiler.h: replace QEMU_NORETURN with G_NORETURNMarc-André Lureau
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).

2022-04-06Replace config-time define HOST_WORDS_BIGENDIANMarc-André Lureau
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.

2021-12-23build: use "meson test" as the test harnessPaolo Bonzini
"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 <pbonzini@redhat.com>

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.

2020-08-21meson: rename included C source files to .c.incPaolo Bonzini
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.
