Jakob Stoklund Olesen aa4b0159da Avoid allocating the same physreg to multiple virtregs in one instruction. ... While that approach works wonders for register pressure, it tends to break everything. This should unbreak the arm-linux builder and fix a number of miscompilations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103946 91177308-0d34-0410-b5e6-96231b3b80d8		2010-05-17 17:18:59 +00:00
