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.

AddressSanitizer RT ================================ This directory contains sources of the AddressSanitizer (ASan) runtime library. Directory structure: README.txt : This file. Makefile.mk : File for make-based build. CMakeLists.txt : File for cmake-based build. asan_*.{cc,h} : Sources of the asan runtime library. scripts/* : Helper scripts. tests/* : ASan unit tests. Also ASan runtime needs the following libraries: lib/interception/ : Machinery used to intercept function calls. lib/sanitizer_common/ : Code shared between various sanitizers. ASan runtime currently also embeds part of LeakSanitizer runtime for leak detection (lib/lsan/lsan_common.{cc,h}). ASan runtime can only be built by CMake. You can run ASan tests from the root of your CMake build tree: make check-asan For more instructions see: https://github.com/google/sanitizers/wiki/AddressSanitizerHowToBuild
