15 years agoMatch this pattern so that we can generate simpler code:
Bill Wendling [Thu, 26 Mar 2009 01:47:50 +0000 (01:47 +0000)]
Match this pattern so that we can generate simpler code:

  %a = ...
  %b = and i32 %a, 2
  %c = srl i32 %b, 1
  %d = br i32 %c,

into

  %a = ...
  %b = and %a, 2
  %c = X86ISD::CMP %b, 0
  %d = X86ISD::BRCOND %c ...

This applies only when the AND constant value has one bit set and the SRL
constant is equal to the log2 of the AND constant. The back-end is smart enough
to convert the result into a TEST/JMP sequence.
