Jingyue Wu 6e67398da9 [NVPTX] enable NaryReassociate in NVPTX ... Summary: We run NaryReassociate right after SLSR because SLSR enables many opportunities for NaryReassociate. For example, in nary-slsr.ll foo((a + b) + c); foo((a + b * 2) + c); foo((a + b * 3) + c); // 2 muls and 6 adds after SLSR: ab = a + b; foo(ab + c); ab2 = ab + b; foo(ab2 + c); ab3 = ab2 + b; foo(ab3 + c); // 6 adds after NaryReassociate: abc = (a + b) + c; foo(abc); ab2c = abc + b; foo(ab2c); ab3c = ab2c + b; foo(ab3c); // 4 adds Test Plan: nary-slsr.ll Reviewers: jholewinski, eliben Reviewed By: eliben Subscribers: jholewinski, llvm-commits Differential Revision: http://reviews.llvm.org/D9066 llvm-svn: 235688		2015-04-24 02:54:06 +00:00
