Subject: glsl: Allow ir_assignment() constructor to not specify condition.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e617a53a74cd27a322fd2dd05ff1c66c6437fde3;p=mesa.git

glsl: Allow ir_assignment() constructor to not specify condition.

We almost never want to specify a condition, and when we do we're
already thinking about it (because we're writing a lowering pass
generating the condition), so a default argument should make the code
more pleasant to read.

NOTE: This is a candidate for the 7.11 branch (we want to be able to
cherry-pick future code).
