* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@351636 91177308-0d34-0410-b5e6-96231b3b80d8

* [Sanitizers] Basic sanitizer Solaris support (PR 33274)Kamil Rytarowski2017-12-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [UBSan] Embed UBSan into ASan runtime (compiler-rt part).Alexey Samsonov2015-04-011-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | Summary: Change the way we use ASan and UBSan together. Instead of keeping two separate runtimes (libclang_rt.asan and libclang_rt.ubsan), embed UBSan into ASan and get rid of libclang_rt.ubsan. If UBSan is not supported on a platform, all UBSan sources are just compiled into dummy empty object files. UBSan initialization code (e.g. flag parsing) is directly called from ASan initialization, so we are able to enforce correct initialization order. This mirrors the approach we already use for ASan+LSan. This change doesn't modify the way we use standalone UBSan.
