Jim Grosbach 8a78dc2600 TableGen: Allow conditional instruction pattern in multiclass. ... Define a 'null_frag' SDPatternOperator node, which if referenced in an instruction Pattern, results in the pattern being collapsed to be as-if '[]' had been specified instead. This allows supporting a multiclass definition where some instaniations have ISel patterns associated and others do not. For example, multiclass myMulti<RegisterClass rc, SDPatternOperator OpNode = null_frag> { def _x : myI<(outs rc:), (ins rc:), []>; def _r : myI<(outs rc:), (ins rc:), [(set rc:, (OpNode rc:))]>; } defm foo : myMulti<GRa, not>; defm bar : myMulti<GRb>; llvm-svn: 160333		2012-07-17 00:47:06 +00:00
