Should I be able to pass a sampler to a function? For instance the
following code aborts when compiled in Mesa 7.0.4:
uniform sampler2D uMap0;
varying vec4 vUV0;
void foo(in sampler2D iTexture, in vec4 iUV) {
return texture2D(iTexture, iUV.st);
}
void main(void)
{
gl_FragColor = foo(uMap0, uUV0);
}
The following assertion fails:
voodoo: shader/slang/slang_codegen.c:1832: _slang_gen_var_decl:
Assertion `!is_sampler_type(&var->type)' failed.
Here's the stacktrace:
