Hal Finkel b359b735d6 [PowerPC] Enable late partial unrolling on the POWER7 ... The P7 benefits from not have really-small loops so that we either have multiple dispatch groups in the loop and/or the ability to form more-full dispatch groups during scheduling. Setting the partial unrolling threshold to 44 seems good, empirically, for the P7. Compared to using no late partial unrolling, this yields the following test-suite speedups: SingleSource/Benchmarks/Adobe-C++/simple_types_constant_folding -66.3253% +/- 24.1975% SingleSource/Benchmarks/Misc-C++/oopack_v1p8 -44.0169% +/- 29.4881% SingleSource/Benchmarks/Misc/pi -27.8351% +/- 12.2712% SingleSource/Benchmarks/Stanford/Bubblesort -30.9898% +/- 22.4647% I've speculatively added a similar setting for the P8. Also, I've noticed that the unroller does not quite calculate the unrolling factor correctly for really tiny loops because it neglects to account for the fact that not every loop body replicant contains an ending branch and counter increment. I'll fix that later. llvm-svn: 225522		2015-01-09 15:51:16 +00:00

libcxx	In early C++11 standard drafts, std::function derived from std::unary_function or std::binary_function if there was only one (or two) parameters. Before C++11 shipped, this restiction was lifted, but libc++ still does this (which is fine). However, the tests still check for this outdated requiremnt. Change then to check for the nested typedefs instead (which are still required by the standard). No change to the library.	2015-01-08 06:36:41 +00:00
