Subject: glsl: Don't hide the type of struct_declaration_list.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=912a429bc529a017a426f06631b31da1c0eaa3ae;p=mesa.git

glsl: Don't hide the type of struct_declaration_list.

I've been trying to derive from this for UBO support, and the slightly
obfuscated types were putting me over the edge.
