This introduced MMX instructions in code that wasn't previously using them, breaking programs using 64-bit vectors and x87 floating-point in the same application. See discussion on the code review for more details. > According to System V i386 ABI: the __m64 type paramater and return > value are passed by MMX registers. But current implementation treats > __m64 as i64 which results in parameter passing by stack and returning > by EDX and EAX. > > This patch fixes the bug (https://bugs.llvm.org/show_bug.cgi?id=41029) > for Linux and NetBSD. > > Patch by Wei Xiao (wxiao3) > > Differential Revision: https://reviews.llvm.org/D59744 llvm-svn: 363790 |
