2016-08-09[sanitizers] Make it possible to XFAIL on the effective target, not just the ↵Daniel Sanders
default. Summary: The triple is not the right thing to XFAIL on since LIT only sees the default triple and not the effective triple chosen by any -target option in the RUN directives. This discrepancy is shown in the table below: Default Triple | Options | XFAIL | LIT's expected result | Desired expectation =================+===================================+========+=======================+==================== mips-linux-gnu | -target mips-linux-gnu | | Pass | Pass mips-linux-gnu | -target mips64-linux-gnu -mabi=64 | | Pass | Pass mips-linux-gnu | -target mips-linux-gnu | mips | Fail | Fail mips-linux-gnu | -target mips64-linux-gnu -mabi=64 | mips | Fail | Fail/Pass* (debatable**) mips-linux-gnu | -target mips-linux-gnu | mips- | Fail | Fail mips-linux-gnu | -target mips64-linux-gnu -mabi=64 | mips- | Fail | Pass* mips-linux-gnu | -target mips-linux-gnu | mips64 | Pass | Pass mips-linux-gnu | -target mips64-linux-gnu -mabi=64 | mips64 | Pass | Fail* mips64-linux-gnu | -target mips-linux-gnu | | Pass | Pass mips64-linux-gnu | -target mips64-linux-gnu -mabi=64 | | Pass | Pass mips64-linux-gnu | -target mips-linux-gnu | mips | Fail | Fail* mips64-linux-gnu | -target mips64-linux-gnu -mabi=64 | mips | Fail | Fail/Pass (debatable**) mips64-linux-gnu | -target mips-linux-gnu | mips- | Pass | Fail* mips64-linux-gnu | -target mips64-linux-gnu -mabi=64 | mips- | Pass | Pass mips64-linux-gnu | -target mips-linux-gnu | mips64 | Fail | Pass* mips64-linux-gnu | -target mips64-linux-gnu -mabi=64 | mips64 | Fail | Fail x64_64-linux-gnu | -target i386-linux-gnu | | Pass | Pass x64_64-linux-gnu | -target x86_64-linux-gnu | | Pass | Pass x64_64-linux-gnu | -target i386-linux-gnu | i386 | Pass | Fail* x64_64-linux-gnu | -target x86_64-linux-gnu | i386 | Pass | Pass x64_64-linux-gnu | -target i386-linux-gnu | x86_64 | Fail | Pass x64_64-linux-gnu | -target x86_64-linux-gnu | x86_64 | Fail | Fail* * These all differ from LIT's current behaviour. ** People's expectations vary depending on whether they know that LIT does a substring match on the default triple or think it's an exact match on an architecture. This patch adds "target-is-${target_arch}" to the available features list and updates the mips XFAIL's to use them. XFAIL'ing on these features will correctly account for the target being tested. Making the table: Options | XFAIL | LIT's expected result ==================================+==================+====================== -target mips-linux-gnu | | Pass -target mips64-linux-gnu -mabi=64 | | Pass -target mips-linux-gnu | target-is-mips | Fail -target mips64-linux-gnu -mabi=64 | target-is-mips | Pass -target mips-linux-gnu | target-is-mips64 | Pass -target mips64-linux-gnu -mabi=64 | target-is-mips64 | Fail -target i386-linux-gnu | | Pass -target x86_64-linux-gnu | | Pass -target i386-linux-gnu | target-is-i386 | Fail -target x86_64-linux-gnu | target-is-i386 | Pass -target i386-linux-gnu | target-is-x86_64 | Pass -target x86_64-linux-gnu | target-is-x86_64 | Fail Reviewers: probinson Subscribers: probinson, kubabrecka, llvm-commits, samsonov Differential Revision: https://reviews.llvm.org/D22802 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@278116 91177308-0d34-0410-b5e6-96231b3b80d8

2015-12-08[PPC64, TSAN] LLVM basic enablement of thread sanitizer for PPC64 (BE and LE)Bill Schmidt
This patch is by Simone Atzeni with portions by Adhemerval Zanella. This contains the LLVM patches to enable the thread sanitizer for PPC64, both big- and little-endian. Two different virtual memory sizes are supported: Old kernels use a 44-bit address space, while newer kernels require a 46-bit address space. There are two companion patches that will be added shortly. There is a Clang patch to actually turn on the use of the thread sanitizer for PPC64. There is also a patch that I wrote to provide interceptor support for setjmp/longjmp on PPC64. Patch discussion at reviews.llvm.org/D12841. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@255057 91177308-0d34-0410-b5e6-96231b3b80d8

2015-11-30[tsan] Fix signals and setjmp/longjmp on OS XKuba Brecka
1) There's a few wrongly defined things in tsan_interceptors.cc, 2) a typo in tsan_rtl_amd64.S which calls setjmp instead of sigsetjmp in the interceptor, and 3) on OS X, accessing an mprotected page results in a SIGBUS (and not SIGSEGV).

2015-11-16[compiler-rt] [tsan] Enable intercept setjmp/longjmp for AArch64Adhemerval Zanella
This patch adds assembly routines to enable setjmp/longjmp for aarch64 on linux. It fixes: * test/tsan/longjmp2.cc * test/tsan/longjmp3.cc * test/tsan/longjmp4.cc * test/tsan/signal_longjmp.cc I also checked with perlbench from specpu2006 (it fails to run with missing setjmp/longjmp intrumentation). git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@253205 91177308-0d34-0410-b5e6-96231b3b80d8
2015-08-05[tsan] Enable tsan for aarch64Adhemerval Zanella
This patch enabled TSAN for aarch64 with 39-bit VMA layout. As defined by tsan_platform.h the layout used is: 0000 4000 00 - 0200 0000 00: main binary 2000 0000 00 - 4000 0000 00: shadow memory 4000 0000 00 - 5000 0000 00: metainfo 5000 0000 00 - 6000 0000 00: - 6000 0000 00 - 6200 0000 00: traces 6200 0000 00 - 7d00 0000 00: - 7d00 0000 00 - 7e00 0000 00: heap 7e00 0000 00 - 7fff ffff ff: modules and main thread stack Which gives it about 8GB for main binary, 4GB for heap and 8GB for modules and main thread stack. Most of tests are passing, with the exception of: * ignore_lib0, ignore_lib1, ignore_lib3 due a kernel limitation for no support to make mmap page non-executable. * longjmp tests due missing specialized assembly routines. These tests are xfail for now. The only tsan issue still showing is: rtl/TsanRtlTest/Posix.ThreadLocalAccesses Which still required further investigation. The test is disable for aarch64 for now. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@244055 91177308-0d34-0410-b5e6-96231b3b80d8

2014-09-18tsan: fix signal_longjmp test in debug modeDmitry Vyukov
In debug mode tsan checks that user accesses access user memory. NULL is not user memory. So the test fails. Allocate real inaccessible memory for the test. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@218069 91177308-0d34-0410-b5e6-96231b3b80d8
