Fiona Glaser b8a330c42a Reassociate: add global reassociation algorithm ... This algorithm (explained more in the source code) takes into account global redundancies by building a "pair map" to find common subexprs. The primary motivation of this is to handle situations like foo = (a * b) * c bar = (a * d) * c where we currently don't identify that "a * c" is redundant. Accordingly, it prioritizes the emission of a * c so that CSE can remove the redundant calculation later. Does not change the actual reassociation algorithm -- only the order in which the reassociated operand chain is reconstructed. Gives ~1.5% floating point math instruction count reduction on a large offline suite of graphics shaders. llvm-svn: 320515		2017-12-12 19:18:02 +00:00
