Subject: glsl/ast: Implicit conversion from double to float is not allowed
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d1509a5848dee57b933139ad2610e99ae09cb5ec;p=mesa.git

glsl/ast: Implicit conversion from double to float is not allowed

Also, renamed get_conversion_operation to avoid
future misunderstandings.
