2021-10-03Practice diagnostic message conventionHirochika Matsumoto-1/+1
2021-08-12Implement `black_box` using intrinsicGary Guo-1/+1
The new implementation allows some `memcpy`s to be optimized away, so the uninit value in ui/sanitize/memory.rs is constructed directly onto the return place. Therefore the sanitizer now says that the value is allocated by `main` rather than `random`.
2021-06-24Re-Annotate the tests with needs-llvm-componentsSimonas Kazlauskas-0/+3
Doesn't work though, because compiletest doesn't process ignores on a per-revision manner.

2021-04-09Auto merge of #81942 - the8472:reduce-ui-test-threads, r=Mark-Simulacrumbors-1/+2
reduce threads spawned by ui-tests The test harness already spawns enough tests to keep all cores busy. Individual tests should keep their own threading to a minimum to avoid context switch overhead. When running ui tests with lld enabled this shaves about 10% off that testsuite on my machine. Resolves #81946
2021-04-09reduce threads spawned by ui-testsThe8472-1/+2
the test harness already spawns enough tests for all cores, individual tests should keep their own threading to a minimum to avoid context switch overhead some tests fail with 1 CGU, so explicit compile flags have been added to keep their old behavior
2021-04-03Maintain supported sanitizers as a target propertySimonas Kazlauskas-3/+2
This commit adds an additional target property – `supported_sanitizers`, and replaces the hardcoded allowlists in argument parsing to use this new property. Fixes #81802

2020-11-12fully exploited the dropped support of LLVM 8DevJPM-1/+0
This commit grepped for LLVM_VERSION_GE, LLVM_VERSION_LT, get_major_version and min-llvm-version and statically evaluated every expression possible (and sensible) assuming that the LLVM version is >=9 now

2020-06-19Rollup merge of #73347 - tmiasko:incompatible-sanitizers, r=nikicManish Goregaokar-3/+12
Diagnose use of incompatible sanitizers Emit an error when incompatible sanitizer are configured through command line options. Previously the last one configured prevailed and others were silently ignored. Additionally use a set to represent configured sanitizers, making it possible to enable multiple sanitizers at once. At least in principle, since currently all of them are considered to be incompatible with others.

2020-06-13compiletest: Add directives to detect sanitizer supportTomasz Miąsko-11/+12
Add needs-sanitizer-{address,leak,memory,thread} directive indicating that test requires target with support for specific sanitizer. This is an addition to the existing needs-sanitizer-support directive indicating that test requires a sanitizer runtime library.
2020-05-14Consistently use LLVM lifetime markers during codegenTomasz Miąsko-0/+31
Ensure that inliner inserts lifetime markers if they have been emitted during codegen. Otherwise if allocas from inlined functions are merged together, lifetime markers from one function might invalidate load & stores performed by the other one.

2020-03-08unix: Don't override existing SIGSEGV/BUS handlersJosh Stone-0/+19
Although `stack_overflow::init` runs very early in the process, even before `main`, there may already be signal handlers installed for things like the address sanitizer. In that case, just leave it alone, and don't bother trying to allocate our own signal stacks either.
2020-03-08Rollup merge of #69800 - tmiasko:address-g, r=nikicMazdak Farrokhzad-3/+2
Compile address sanitizer test with debuginfo This makes error-pattern to match regardless of current configuration of `rust.debuginfo-level-tests` in `config.toml`.

2020-03-03Add test for -Znew-llvm-pass-manager -Clto=thin -Zsanitizer=...Tomasz Miąsko-0/+27
Additionally verify that the current implementation of LLVM version check (which uses lexicographic ordering) is good enough to exclude versions before LLVM 9, where the new LLVM pass manager is unsupported.
