Maksim Panchenko 85b99eb7b7 Eliminate nop instruction in input and derive alignment. ... Summary: Nop instructions are primarily used for alignment purposes on the input. We remove all nops when we build CFG and derive alignment of basic blocks based on existing alignment and a presence of nops before it. This will not always work as some basic blocks will be naturally aligned without necessity for nops. However, it's better than random alignment. We would also add heuristics for BB alignment based on execution profile. (cherry picked from FBD2561740)		2015-10-20 10:51:17 -07:00
