Dan Gohman b158fd751c Work around an interaction between fast-isel and regalloc=local. The ... local register allocator's physreg liveness doesn't recognize subregs, so it doesn't know that defs of %ecx that are immediately followed by uses of %cl aren't dead. This comes up due to the way fast-isel emits shift instructions. This is a temporary workaround. Arguably, local regalloc should handle subreg references correctly. On the other hand, perhaps fast-isel should use INSERT_SUBREG instead of just assigning to the most convenient super-register of %cl when lowering shifts. This fixes MultiSource/Benchmarks/MallocBench/espresso, MultiSource/Applications/hexxagon, and others, under -fast. llvm-svn: 56947		2008-10-02 14:56:12 +00:00
