Assertion `PureOperatorBuiltins == false' failed on use of texture2D #3629

Open amalon opened 1 week ago

amalon commented 1 week ago

I know texture2D is deprecated, but glslangValidator asserts when its used. Here's an example:

texture2d.frag:

#version 330 core
uniform sampler2D tex;
void main()
{
    texture2D(tex, vec2(0));
}
$ glslangValidator -l -S frag texture2d.frag 
glslangValidator: /usr/src/debug/glslang/glslang-14.1.0/glslang/MachineIndependent/ParseHelper.cpp:2846: void glslang::TParseContext::nonOpBuiltInCheck(const glslang::TSourceLoc&, const glslang::TFunction&, glslang::TIntermAggregate&): Assertion `PureOperatorBuiltins == false' failed.
Aborted (core dumped)
