Subject: intel/ir: Represent physical edge of unconditional CONTINUE instruction.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6965a02e09de2d31e5fa951ffa2ae401b2197fb1;p=mesa.git

intel/ir: Represent physical edge of unconditional CONTINUE 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 control flow isn't uniform across channels of the same SIMD
thread.
