Tobias Grosser cb73f150d4 Translate power-of-two floor-division into ashr ... Power-of-two floor divisions can be translated into an arithmetic shift operation. This allows us to replace a complex lowering that requires division operations: %pexp.fdiv_q.0 = sub i64 %21, 128 %pexp.fdiv_q.1 = add i64 %pexp.fdiv_q.0, 1 %pexp.fdiv_q.2 = icmp slt i64 %21, 0 %pexp.fdiv_q.3 = select i1 %pexp.fdiv_q.2, i64 %pexp.fdiv_q.1, i64 %21 %pexp.fdiv_q.4 = sdiv i64 %pexp.fdiv_q.3, 128 with a simple ashr: %polly.fdiv_q.shr = ashr i64 %21, 7 llvm-svn: 238905		2015-06-03 06:31:30 +00:00
