| * | Fix bugs in cpuid.h. | Akira Hatanaka | 2014-09-20 | 1 | -0/+18 |
| This commit makes two changes: - Remove the push and pop instructions that were saving and restoring %ebx before and after cpuid in 32-bit pic mode. We were doing this to ensure we don't lose the GOT address in pic register %ebx, but this isn't necessary because the GOT address is kept in a virtual register. - In 64-bit mode, preserve base register %rbx around cpuid. This fixes PR20311 and rdar://problem/17686779. llvm-svn: 218173 | |||||
