Summary: The assembler tries to reuse the destination register for memory operations whenever it can but it's not possible to do so if the destination register is not a GPR. Example: ldc1 $f0, sym should expand to: lui $at, %hi(sym) ldc1 $f0, %lo(sym)($at) It's entirely wrong to expand to: lui $f0, %hi(sym) ldc1 $f0, %lo(sym)($f0) Reviewers: dsanders Reviewed By: dsanders Differential Revision: http://reviews.llvm.org/D4173 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211169 91177308-0d34-0410-b5e6-96231b3b80d8
