* [asan] under handle_abort=1 option intercept SIGABRT in addition to ↵Kostya Serebryany2015-05-051-0/+24
| | | | | | SIGSEGV/SIGBUS. Among other things this will allow to set up a death callback for SIGABRT and thus properly handle assert() in lib/Fuzzer llvm-svn: 236474
* [Sanitizer] Fix getpwnam test on ppc64le Fedora 21.Jay Foad2015-04-231-1/+2
| | | | | | | | | | | | | | | | Summary: On ppc64le Fedora 21, getpwnam_r("no-such-user", ...) returns ENOENT instead of 0. Tolerate this in the test case. Reviewers: eugenis Reviewed By: eugenis Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D9233 llvm-svn: 235654
* tsan: fix signal handling during stop-the-worldDmitry Vyukov2015-03-051-0/+41
| | | | | | | | | | | | | | | | | | | | | Long story short: stop-the-world briefly resets SIGSEGV handler to SIG_DFL. This breaks programs that handle and continue after SIGSEGV (namely JVM). See the test and comments for details. This is reincarnation of reverted r229678 (http://reviews.llvm.org/D7722). Changed: - execute TracerThreadDieCallback only on tracer thread - reset global data in TracerThreadSignalHandler/TracerThreadDieCallback - handle EINTR from waitpid Add 3 new test: - SIGSEGV during leak checking - StopTheWorld operation during signal storm from an external process - StopTheWorld operation when the program generates and handles SIGSEGVs http://reviews.llvm.org/D8032 llvm-svn: 231367

* [Sanitizer] Introduce "stack_trace_format" runtime flag.Alexey Samsonov2014-11-061-10/+10
| | | | | | | | | | | | | | | | This flag can be used to specify the format of stack frames - user can now provide a string with placeholders, which should be printed for each stack frame with placeholders replaced with actual data. For example "%p" will be replaced by PC, "%s" will be replaced by the source file name etc. "DEFAULT" value enforces default stack trace format currently used in all the sanitizers except TSan. This change also implements __sanitizer_print_stack_trace interface function in TSan. llvm-svn: 221469
* Disable XFAIL on ARM since the x86_64 specific code is isolatedRenato Golin2014-11-051-2/+0

* Get the Linux ptrace test working on PowerPC64Jay Foad2014-11-051-1/+18
| | | | | | | | | | | | | | The test refers to user_regs_struct.rip so it can only ever have worked on x86-64. Put this code inside an appropriate #if, and add a similar case for PowerPC64. (If we do likewise for ARM we can probably remove the XFAILs, but I have no way of testing that.) Those changes are enough to get the test working for me on big-endian PowerPC64 Fedora 19.

* Mark sanitizer tests XFAIL on ARMv7Renato Golin2014-10-081-0/+1
| | | | | | | | | ASAN, UBSAN and profile tests that don't work with arm-linux-gnueabi and android also don't work on armv7l-linux-gnueabihf. Some of the tests have known causes, others not yet. In order to get a green bot, I'm disabling those tests for now and will investigate when the priority rises. llvm-svn: 219343

| | | | | | | | | | | | | | | | | | The patch adds better target_triple and target_arch defaults for lit tests, which allows us to XFAIL tests based on architecture. Was: target_triple = LLVM_DEFAULT_TARGET_TRIPLE target_arch = HOST_ARCH Now: target_triple = COMPILER_RT_TEST_TARGET_TRIPLE , otherwise LLVM_DEFAULT_TARGET_TRIPLE target_arch = first item in COMPILER_RT_TEST_TARGET_TRIPLE Differential Revision: http://reviews.llvm.org/D3855 llvm-svn: 209256
