[Mesa-dev] [PATCH 11/50 v3] glsl/ast: Add 64-bit integer support to conversion functions
Ian Romanick

Tue Nov 29 03:25:26 UTC 2016
From: Dave Airlie <airlied at redhat.com>
This adds support to call the new operations on conversions.
v2 (idr): Delete an unnecessary break-statement. Noticed by Matt. Add
a missing blank line. Noticed by Ian.
v3 (idr): "cut them down later" => Remove ir_unop_b2u64 and
ir_unop_u642b. Handle these with extra i2u or u2i casts just like
uint(bool) and bool(uint) conversion is done.
