From d7984710ae27008a4dffbfc4a3452bbf3beda347 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Wed, 5 Aug 2015 15:17:59 +0000 Subject: [PATCH] [tsan] Enable tsan for aarch64 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. llvm-svn: 244055 --- compiler-rt/cmake/config-ix.cmake | 2 +- .../lib/sanitizer_common/sanitizer_linux.cc | 51 ++++++++++++++++++++++ compiler-rt/lib/sanitizer_common/sanitizer_linux.h | 2 +- .../sanitizer_common/sanitizer_linux_libcdep.cc | 18 ++++++-- .../sanitizer_stoptheworld_linux_libcdep.cc | 27 ++++++++++-- compiler-rt/lib/tsan/rtl/tsan_interceptors.cc | 18 +++++--- compiler-rt/lib/tsan/rtl/tsan_platform.h | 27 ++++++++++++ compiler-rt/lib/tsan/rtl/tsan_platform_linux.cc | 3 ++ compiler-rt/lib/tsan/rtl/tsan_rtl.h | 2 +- compiler-rt/lib/tsan/tests/rtl/tsan_posix.cc | 6 +++ compiler-rt/test/tsan/ignore_lib0.cc | 3 ++ compiler-rt/test/tsan/ignore_lib1.cc | 2 + compiler-rt/test/tsan/ignore_lib3.cc | 3 ++ compiler-rt/test/tsan/longjmp.cc | 3 +- compiler-rt/test/tsan/longjmp2.cc | 3 +- compiler-rt/test/tsan/longjmp3.cc | 3 +- compiler-rt/test/tsan/longjmp4.cc | 3 +- compiler-rt/test/tsan/map32bit.cc | 1 + compiler-rt/test/tsan/mmap_large.cc | 2 +- compiler-rt/test/tsan/signal_longjmp.cc | 3 +- compiler-rt/test/tsan/test.h | 2 +- 21 files changed, 161 insertions(+), 23 deletions(-) diff --git a/compiler-rt/cmake/config-ix.cmake b/compiler-rt/cmake/config-ix.cmake index 1fc4424..f5695a2 100644 --- a/compiler-rt/cmake/config-ix.cmake +++ b/compiler-rt/cmake/config-ix.cmake @@ -260,7 +260,7 @@ filter_available_targets(LSAN_SUPPORTED_ARCH x86_64 mips64 mips64el) filter_available_targets(MSAN_SUPPORTED_ARCH x86_64 mips64 mips64el) filter_available_targets(PROFILE_SUPPORTED_ARCH x86_64 i386 i686 arm mips mips64 mipsel mips64el aarch64 powerpc64 powerpc64le) -filter_available_targets(TSAN_SUPPORTED_ARCH x86_64 mips64 mips64el) +filter_available_targets(TSAN_SUPPORTED_ARCH x86_64 mips64 mips64el aarch64) filter_available_targets(UBSAN_SUPPORTED_ARCH x86_64 i386 i686 arm aarch64 mips mipsel mips64 mips64el powerpc64 powerpc64le) filter_available_targets(SAFESTACK_SUPPORTED_ARCH x86_64 i386 i686) diff --git a/compiler-rt/lib/sanitizer_common/sanitizer_linux.cc b/compiler-rt/lib/sanitizer_common/sanitizer_linux.cc index 681b6f3..3da165d 100644 --- a/compiler-rt/lib/sanitizer_common/sanitizer_linux.cc +++ b/compiler-rt/lib/sanitizer_common/sanitizer_linux.cc @@ -926,6 +926,57 @@ uptr internal_clone(int (*fn)(void *), void *child_stack, int flags, void *arg, : "memory", "$29" ); return res; } +#elif defined(__aarch64__) +uptr internal_clone(int (*fn)(void *), void *child_stack, int flags, void *arg, + int *parent_tidptr, void *newtls, int *child_tidptr) { + long long res; + if (!fn || !child_stack) + return -EINVAL; + CHECK_EQ(0, (uptr)child_stack % 16); + child_stack = (char *)child_stack - 2 * sizeof(unsigned long long); + ((unsigned long long *)child_stack)[0] = (uptr)fn; + ((unsigned long long *)child_stack)[1] = (uptr)arg; + + register int (*__fn)(void *) __asm__("x0") = fn; + register void *__stack __asm__("x1") = child_stack; + register int __flags __asm__("x2") = flags; + register void *__arg __asm__("x3") = arg; + register int *__ptid __asm__("x4") = parent_tidptr; + register void *__tls __asm__("x5") = newtls; + register int *__ctid __asm__("x6") = child_tidptr; + + __asm__ __volatile__( + "mov x0,x2\n" /* flags */ + "mov x2,x4\n" /* ptid */ + "mov x3,x5\n" /* tls */ + "mov x4,x6\n" /* ctid */ + "mov x8,%9\n" /* clone */ + + "svc 0x0\n" + + /* if (%r0 != 0) + * return %r0; + */ + "cmp x0, #0\n" + "bne 1f\n" + + /* In the child, now.
