As the diffstat shows, HLSL_CLASS_OBJECT does not really have much in common.
Resource types (TEXTURE, SAMPLER, UAV) sometimes behave similarly to each other,
but do not generally behave similarly to effect-specific types (string, shader,
state, view). Most consumers of HLSL_CLASS_OBJECT subsequently check the base
type anyway.
Hence we want to replace HLSL_TYPE_* with individual classes for object types.
As a first step, change the last few places that only check HLSL_CLASS_OBJECT.
Properly passing the inverse-trig.shader_test tests whose qualifiers
have been removed requires making spirv.c capable of handling ABS.
The same happens for the ps_3_0 equality test in
float-comparison.shader_test.
Otherwise we may get a failing
"hlsl_types_are_equal(arg1->data_type, arg2->data_type)"
assertion on hlsl_new_binary_expr() when creating the MUL.
This happens in the test introducing in the following patch:
int a, b, c;
void main(out float4 res : COLOR1, in float4 pos : position, out float4 out_pos : sv_position)
{
out_pos = pos;
res = a ? b/1000.0 : c/1000.0;
}
