David Sehr e37f7ab590 The current X86 NOP padding uses one long NOP followed by the remainder in ... one-byte NOPs. If the processor actually executes those NOPs, as it sometimes does with aligned bundling, this can have a performance impact. From my micro-benchmarks run on my one machine, a 15-byte NOP followed by twelve one-byte NOPs is about 20% worse than a 15 followed by a 12. This patch changes NOP emission to emit as many 15-byte (the maximum) as possible followed by at most one shorter NOP. llvm-svn: 176464		2013-03-05 00:02:23 +00:00
