------------------------------------------------------------------------ r195973 | dsanders | 2013-11-30 13:47:57 +0000 (Sat, 30 Nov 2013) | 5 lines [mips][msa] MSA loads and stores have a 10-bit offset. Account for this when lowering FrameIndex. This prevents the compiler from emitting invalid ld.[bhwd]'s and st.[bhwd]'s when the stack frame is between 512 and 32,768 bytes in size. ------------------------------------------------------------------------ Review of this commit by Matheus Almeida revealed that it is still possible to emit invalid code (when the offset is not a multiple of the element size). However, we agreed that this commit still represents an improvement since it fixes many cases that previously emitted invalid code, and does not cause any cases that previously emitted valid code to emit invalid code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@196049 91177308-0d34-0410-b5e6-96231b3b80d8
