Eric Christopher	eb19e9e9fc	Turn on list-ilp scheduling by default on x86 and x86-64, fix up ... testcases accordingly. Some are currently xfailed and will be filed as bugs to be fixed or understood. Performance results: roughly neutral on SPEC some micro benchmarks in the llvm suite are up between 100 and 150%, only a pair of regressions that are due to be investigated john-the-ripper saw: 10% improvement in traditional DES 8% improvement in BSDI DES 59% improvement in FreeBSD MD5 67% improvement in OpenBSD Blowfish 14% improvement in LM DES Small compile time impact. llvm-svn: 127208	2011-03-08 02:42:25 +00:00
Dan Gohman	8fdda8a655	This test doesn't need the ssp attribute. ... llvm-svn: 105440	2010-06-04 00:14:48 +00:00
Daniel Dunbar	b9ea94c990	Eliminate uses of %prcontext. ... - I'd appreciate it if someone else eyeballs my changes to make sure I captured the intent of the test. llvm-svn: 81083	2009-09-05 11:35:16 +00:00
Evan Cheng	78a4eb844b	Teach LSR to optimize more loop exit compares, i.e. change them to use postinc iv value. Previously LSR would only optimize those which are in the loop latch block. However, if LSR can prove it is safe (and profitable), it's now possible to change those not in the latch blocks to use postinc values. ... Also, if the compare is the only use, LSR would place the iv increment instruction before the compare instead in the latch. llvm-svn: 71485	2009-05-11 22:33:01 +00:00
