Shuxin Yang 7d72cf892e This change is to implement following rules under the condition C_A and/or C_R ... --------------------------------------------------------------------------- C_A: reassociation is allowed C_R: reciprocal of a constant C is appropriate, which means - 1/C is exact, or - reciprocal is allowed and 1/C is neither a special value nor a denormal. ----------------------------------------------------------------------------- rule1: (X/C1) / C2 => X / (C2*C1) (if C_A) => X * (1/(C2*C1)) (if C_A && C_R) rule 2: X*C1 / C2 => X * (C1/C2) if C_A rule 3: (X/Y)/Z = > X/(Y*Z) (if C_A && at least one of Y and Z is symbolic value) rule 4: Z/(X/Y) = > (Z*Y)/X (similar to rule3) rule 5: C1/(X*C2) => (C1/C2) / X (if C_A) rule 6: C1/(X/C2) => (C1*C2) / X (if C_A) rule 7: C1/(C2/X) => (C1/C2) * X (if C_A) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172488 91177308-0d34-0410-b5e6-96231b3b80d8		2013-01-14 22:48:41 +00:00
