History
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)

This directory contains test cases for the instcombine transformation.  The
dated tests are actual bug tests, whereas the named tests are used to test
for features that the this pass should be capable of performing.
