b63ca0a0 - [Sanitizers][test] XFAIL long double tests on Solaris/sparc

Wed, 09 Feb 2022 08:20:21 +0000

[Sanitizers][test] XFAIL long double tests on Solaris/sparcAs reported in Issue #41838, `clang` doesn't correctly implement `longdouble` on 32-bit Solaris/SPARC: the psABI requires this to be an 128-bittype. Four sanitizer tests currently `FAIL` for this reason.While there is a WIP patch to fix `clang` (D89130), it isn't complete yet and I've hit somany brick walls while trying to finish it that I'm unsure if I ever will.This patch therefore `XFAIL`s those tests in the meantime.Tested on `sparcv9-sun-solaris2.11`.Differential Revision: https://reviews.llvm.org/D119016 List of files: /llvm-project-15.0.7/compiler-rt/test/ubsan/TestCases/Float/cast-overflow.cpp

76e85ae2 - [clang][Sparc] Default to -mcpu=v9 for Sparc V8 on Solaris

Fri, 11 Sep 2020 07:53:19 +0000

[clang][Sparc] Default to -mcpu=v9 for Sparc V8 on SolarisAs reported in Bug 42535, `clang` doesn't inline atomic ops on 32-bitSparc, unlike `gcc` on Solaris. In a 1-stage build with `gcc`, only twotestcases are affected (currently `XFAIL`ed), while in a 2-stage build morethan 100 tests `FAIL` due to this issue.The reason for this `gcc`/`clang` difference is that `gcc` on 32-bitSolaris/SPARC defaults to `-mpcu=v9` where atomic ops are supported, unlikewith `clang`'s default of `-mcpu=v8`. This patch changes `clang` to use`-mcpu=v9` on 32-bit Solaris/SPARC, too.Doing so uncovered two bugs:`clang -m32 -mcpu=v9` chokes with any Solaris system headers included: /usr/include/sys/isa_defs.h:461:2: error: "Both _ILP32 and _LP64 are defined" #error "Both _ILP32 and _LP64 are defined"While `clang` currently defines `__sparcv9` in a 32-bit `-mcpu=v9`compilation, neither `gcc` nor Studio `cc` do. In fact, the Studio 12.6`cc(1)` man page clearly states: These predefinitions are valid in all modes: [...] __sparcv8 (SPARC) __sparcv9 (SPARC -m64)At the same time, the patch defines `__GCC_HAVE_SYNC_COMPARE_AND_SWAP_[1248]`for a 32-bit Sparc compilation with any V9 cpu. I've also changed`MaxAtomicInlineWidth` for V9, matching what `gcc` does and the OracleDeveloper Studio 12.6: C User's Guide documents (Ch. 3, Support for AtomicTypes, 3.1 Size and Alignment of Atomic C Types).The two testcases that had been `XFAIL`ed for Bug 42535 are un-`XFAIL`edagain.Tested on `sparcv9-sun-solaris2.11` and `amd64-pc-solaris2.11`.Differential Revision: https://reviews.llvm.org/D86621 List of files: /llvm-project-15.0.7/compiler-rt/test/ubsan/TestCases/Float/cast-overflow.cpp

3efd1c51 - [Sanitizers, test] Fix sanitizer tests on Solaris (PR 33274)

Wed, 17 Jan 2018 12:26:04 +0000

[Sanitizers, test] Fix sanitizer tests on Solaris (PR 33274)Summary:This patch (on top of the previous two (https://reviews.llvm.org/D40898 andhttps://reviews.llvm.org/D40899) complete the compiler-rt side of the the Solarissanitizer port.It contains the following sets of changes:* For the time being, the port is for 32-bit x86 only, so reject the various tests on x86_64.* When compiling as C++, resp. only declares _setjmp and _longjmp inside namespace std.* MAP_FILE is a Windows feature. While e.g. Linux provides a no-op compat define, Solaris does not.* test/asan/TestCases/Posix/coverage.cc was initially failing like this:/vol/gcc/src/llvm/llvm/local/projects/compiler-rt/lib/sanitizer_common/scripts/sancov.py: 4 files merged; 2 PCs totalrm: cannot remove '/var/gcc/llvm/local/projects/compiler-rt/test/asan/I386SunOSConfig/TestCases/Posix/Output/coverage': Invalid argument Further digging revealed that the rm was trying to remove the running test's working directory which failed as observed. cd'ing out of the dir before let the test pass.* Two tests needed a declaration of alloca. I've now copied the existing code from test/asan/TestCases/alloca_constant_size.cc, but it may be more profitable and maintainable to have a common testsuite header where such code is collected.* Similarly, Solaris' printf %p format doesn't include the leading 0x.* In test/asan/TestCases/malloc-no-intercept.c, I had to undef __EXTENSIONS__ (predefined by clang for no apparent reason) to avoid conflicting declarations for memalign.* test/ubsan/TestCases/Float/cast-overflow.cpp has different platform dependent ways to define BYTE_ORDER and friends. Why not just use __BYTE_ORDER__ and friends as predefined by clang and gcc?Patch by Rainer Orth.Reviewers: kcc, alekseyshlReviewed By: alekseyshlSubscribers: srhines, kubamracek, mgorny, krytarowski, fedor.sergeev, JDevlieghere, llvm-commits, #sanitizersTags: #sanitizersDifferential Revision: https://reviews.llvm.org/D40900llvm-svn: 322635 List of files: /llvm-project-15.0.7/compiler-rt/test/ubsan/TestCases/Float/cast-overflow.cpp

UBSan: Enable runtime library tests on Windows, and get most tests passing.Specifically:- Disable int128 tests on Windows, as MSVC cl.exe does not support int128, so we might not have been able to build the runtime with int128 support.- XFAIL the vptr tests as we lack Microsoft ABI support.- XFAIL enum.cpp as UBSan fails to add the correct instrumentation code for some reason.- Modify certain tests that build executables multiple times to use unique names for each executable. This works around a race condition observed on Windows.- Implement IsAccessibleMemoryRange for Windows to fix the last misaligned.cpp test.- Introduce a substitution for testing crashes on Windows using KillTheDoctor.Differential Revision: http://reviews.llvm.org/D10864llvm-svn: 241303 List of files: /llvm-project-15.0.7/compiler-rt/test/ubsan/TestCases/Float/cast-overflow.cpp
