The register storage class is now represented in
vkd3d_register_builtins, so the spirv_compiler_emit_io_register()
doesn't need to know it from the caller.
Instead of returning nonsense (such as, currently, a type with zero size).
In practice this improves error reporting for shaders such as the following:
void func(float x[])
{
float y[] = {x};
}
Currently this outputs a nonsense
test.hlsl:1:19: E5002: Implicit size arrays not allowed in function parameters.
test.hlsl:3:7: E5002: Implicit size arrays need to be initialized.
With this patch the second warning is removed.
Some test programs, particularly the shader runner, are built from
many different files nowadays, and a line number is relatively
cumbersome to use if you don't know which file that line comes from.
These are redundant either because we already have a broader tag like
"sm<6", or because the tests are never executed with the GLSL runner in
the first place.
Instead of using DCL_INPUT.
The main goal here is to eventually get rid of the I/O
declaration instructions. A positive side effect is that we don't
add a useless barrier to shaders which have a DCL_INPUT instruction
in the patch constant phase but don't actually read OUTCONTROLPOINT
registers.
