[PATCH] D29436: RegisterCoalescer: Fix joinReservedPhysReg()

[Matthias Braun via Phabricator via llvm-commits]

MatzeB added a comment.

I will try to update the tests tomorrow. BTW: For testing regalloc infrastructure I found that you do not need to invent new instructions, just take an existing one (like NOP) and add implicit def and use operands in your .mir test case :)
