Subject: glsl2: Move constant_expression_value method to ir_rvalue.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e340854115f2562109c91fa908ffe6628432f989;p=mesa.git

glsl2: Move constant_expression_value method to ir_rvalue.

This prevents top-level callers from asking for the value of something
that is guaranteed not to have one.
