and forget about the previously used accumulator. Coming up with a simple testcase is not easy, as this highly depends on what the register allocator is doing: this issue showed up while working with the PBQP allocator, which produced a different allocation scheme. A testcase would need to come up with chain starting in D[0-7], then moving to D[8-15], followed by a call to a function whose regmask clobbers the starting accumulator in D[0-7], then another use of the chain. Fixed some formatting, added some invariant checks while there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@216721 91177308-0d34-0410-b5e6-96231b3b80d8
