Subject: intel/ir: Represent physical edge of ELSE instruction.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=eeaad2992cc45c22f5e188d0a814db795112964d;p=mesa.git

intel/ir: Represent physical edge of ELSE instruction.

This edge doesn't exist in the original scalar program, but it
represents a potential control flow path the EU will take in cases
where the condition isn't uniform across channels of the same SIMD
thread.
