glsl: subroutine signatures must match exactly (!5125) · Merge requests · Mesa / mesa

From GLSL 4.60.7 spec, section 6.1.2 "Subroutines":

It is a compile-time error if arguments and return type don’t match between the function and each associated subroutine type.

Before, if subroutine type and implementation function were declared with types, that could be implicitly converted, it led to a runtime crash.
