* clang: allow -fstack-clash-protection on FreeBSDEd Maste2020-11-251-1/+1
| | | | | | | | | | | | | | | | | -fstack-clash-protection was added in Clang commit e67cbac81211 but was enabled only on Linux. It should work fine on FreeBSD as well, so enable it. To be discussed and upstreamed with a test. The OS test should probably just be removed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [PowerPC] Add clang -msvr4-struct-return for 32-bit ELF Summary: Change the default ABI to be compatible with GCC. For 32-bit ELF targets other than Linux, Clang now returns small structs in registers r3/r4. This affects FreeBSD, NetBSD, OpenBSD. There is no change for 32-bit Linux, where Clang continues to return all structs in memory. Add clang options -maix-struct-return (to return structs in memory) and -msvr4-struct-return (to return structs in registers) to be compatible with gcc. These options are only for PPC32; reject them on PPC64 and other targets. The options are like -fpcc-struct-return and -freg-struct-return for X86_32, and use similar code. To actually return a struct in registers, coerce it to an integer of the same size. LLVM may optimize the code to remove unnecessary accesses to memory, and will return i32 in r3 or i64 in r3:r4.

| | | | | | | | | | | | | | | | | | | | | Restore functionality of --sysroot on FreeBSD after b18cb9c47 After b18cb9c47, clang would sometimes prefer the host C++ includes (e.g. in /usr/include/c++/v1) before those specified via --sysroot. While this behavior may be desirable on Linux, it is not so on FreeBSD, where we make extensive use of --sysroot during the build of the base system. In that case, clang must *not* search outside the sysroot, except for its own internal headers. Add an override addLibCxxIncludePaths() to restore the old behavior, which is to simply append /usr/include/c++/v1 to the specified sysroot. While here, apply clang-format to the FreeBSD specific toolchain files. Fixes PR44923. Notes: svn path=/projects/clang1000-import/; revision=357999

This uses the new layout of the upstream repository, which was recently migrated to GitHub, and converted into a "monorepo". That is, most of the earlier separate sub-projects with their own branches and tags were consolidated into one top-level directory, and are now branched and tagged together. Updating the vendor area to match this layout is next. Notes: svn path=/head/; revision=355940
