Bug ID: 102021
Summary: ir validation assert on valid GLSL
Product: Mesa
Version: git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: glsl-compiler
Assignee: mesa-dev@lists.freedesktop.org

test to demonstrate error.
I've written a cut down test that shows a problem virgl hits.
It triggers an assert in the validation that the ir->type and
ir->operands[0]->type for an abs op are the same and they aren't.
temp0[1].x = float(inversesqrt( abs(temp0[0]).x));
temp0[1].y = float(inversesqrt( abs(temp0[0]).y));
is the construct that the compiler squashes incorrectly.
Not sure what pass is responsible for this yet.
