2017-12-14[Sanitizers] Basic sanitizer Solaris support (PR 33274)Kamil Rytarowski
Summary: This is the first mostly working version of the Sanitizer port to 32-bit Solaris/x86. It is currently based on Solaris 11.4 Beta. This part was initially developed inside libsanitizer in the GCC tree and should apply to both. Subsequent parts will address changes to clang, the compiler-rt build system and testsuite. I'm not yet sure what the right patch granularity is: if it's profitable to split the patch up, I'd like to get guidance on how to do so. Most of the changes are probably straightforward with a few exceptions: * The Solaris syscall interface isn't stable, undocumented and can change within an OS release. The stable interface is the libc interface, which I'm using here, if possible using the internal _-prefixed names. * While the patch primarily target 32-bit x86, I've left a few sparc changes in. They cannot currently be used with clang due to a backend limitation, but have worked fine inside the gcc tree. * Some functions (e.g. largefile versions of functions like open64) only exist in 32-bit Solaris, so I've introduced a separate SANITIZER_SOLARIS32 to check for that. The patch (with the subsequent ones to be submitted shortly) was tested on i386-pc-solaris2.11. Only a few failures remain, some of them analyzed, some still TBD: AddressSanitizer-i386-sunos :: TestCases/Posix/concurrent_overflow.cc AddressSanitizer-i386-sunos :: TestCases/init-order-atexit.cc AddressSanitizer-i386-sunos :: TestCases/log-path_test.cc AddressSanitizer-i386-sunos :: TestCases/malloc-no-intercept.c AddressSanitizer-i386-sunos-dynamic :: TestCases/Posix/concurrent_overflow.cc AddressSanitizer-i386-sunos-dynamic :: TestCases/Posix/start-deactivated.cc AddressSanitizer-i386-sunos-dynamic :: TestCases/default_options.cc AddressSanitizer-i386-sunos-dynamic :: TestCases/init-order-atexit.cc AddressSanitizer-i386-sunos-dynamic :: TestCases/log-path_test.cc AddressSanitizer-i386-sunos-dynamic :: TestCases/malloc-no-intercept.c SanitizerCommon-Unit :: ./Sanitizer-i386-Test/MemoryMappingLayout.DumpListOfModules SanitizerCommon-Unit :: ./Sanitizer-i386-Test/SanitizerCommon.PthreadDestructorIterations Maybe this is good enough the get the ball rolling.

2017-02-09Remove strict tid checks from the mac implementation of BlockingMutexFrancis Ricci
Summary: This patch unifies the behavior of BlockingMutex on linux and mac, resolving problems that can arise when BlockingMutex is used in code shared by the two platforms but has different behavior depending on the platform. No longer requires that the calling thread own the mutex for CheckLocked calls to pass.
