* [Sanitizers] Remove clang_rt.sancov_{begin,end} on SolarisRainer Orth2019-07-081-5/+0
| | | | | | | | | | | | | | | | There's no point to manually create the __start___sancov_guards and __stop___sancov_guards sections and labels on Solaris any longer. They were originally introduced in https://reviews.llvm.org/D40899 and https://reviews.llvm.org/D40903. - The Solaris 11.4 ld supports creating them out of the box. - We already unconditionally use Solaris 11.4 features like the ld -z gnu-version-script-compat option and fully working .preinit_array support in compiler-rt. - The current files don't assemble on SPARC because the assembler syntax may be different between /bin/as and GNU as. Tested on amd64-pc-solaris2.11. Differential Revision: https://reviews.llvm.org/D63601 llvm-svn: 365399
* [Sanitizers, CMake] Basic sanitizer Solaris support (PR 33274)Alex Shlyapnikov2017-12-221-0/+5
Summary: This patch, on top of https://reviews.llvm.org/D40898, contains the build system changes necessary to enable the Solaris/x86 sanitizer port. The only issue of note is the libclang_rt.sancov_{begin, end} libraries: clang relies on the linker automatically defining __start_SECNAME and __stop_SECNAME labels for sections whose names are valid C identifiers. This is a GNU ld extension not present in the ELF gABI, also implemented by gold and lld, but not by Solaris ld. To work around this, I automatically link the sancov_{begin,end} libraries into every executable for now. There seems to be now way to build individual startup objects like crtbegin.o/crtend.o, so I've followed the lead of libclang_rt.asan-preinit which also contains just a single object.
