* Set max atomic size for PowerPC.gkoehler2020-06-041-1/+4
| | | | | | | | | | | | 32-bit PowerPC doesn't have instructions for lock-free atomic ops on 8-byte values, and needs libcalls like __atomic_fetch_add_8(). In code like "_Atomic long long a; a++;", clang doesn't emit a libcall. This was causing linker errors on symbols like __sync_fetch_and_add_8. Now that LLVM knows the max atomic size, its AtomicExpandPass changes these 8-byte ops into libcalls. ok mortimer@

* When generating code for OpenBSD/powerpc, avoid unaligned floating-pointkettenis2019-02-181-0/+8
| | | | | | | | | | | | load and store instructions. The vast majority of PowerPC CPUs that OpenBSD runs on don't implement those and will generate an alignment exceptions. While we do emulate lfd and stfd (to work around GCC bugs), we don't emulate lfs and stfs. It is way more efficient to have the compiler generate code that only uses aligned load and store instructions. Based on a diff from Georg Koehler. ok patrick@, visa@
