For processors with the G5-like instruction-grouping scheme, this helps avoid early group termination due to a write-after-write dependency within the group. It should also help on pipelined embedded cores. On POWER7, over the test suite, this gives an average 0.5% speedup. The largest speedups are: SingleSource/Benchmarks/Stanford/Quicksort - 33% MultiSource/Applications/d/make_dparser - 21% MultiSource/Benchmarks/FreeBench/analyzer/analyzer - 12% MultiSource/Benchmarks/MiBench/telecomm-FFT/telecomm-fft - 12% Largest slowdowns: SingleSource/Benchmarks/Stanford/Bubblesort - 23% MultiSource/Benchmarks/Prolangs-C++/city/city - 21% MultiSource/Benchmarks/BitBench/uuencode/uuencode - 16% MultiSource/Benchmarks/mediabench/mpeg2/mpeg2dec/mpeg2decode - 13% llvm-svn: 158719 |
