I am probably missing something here, but why do you need a new register

you just allow LOAD with TGSI_FILE_CONSTANT and achieve the same thing?
Or do you need to know how it's going to be accessed in advance?
With bindless, LOAD can take a CONST I believe [which contains the
value of the bindless id]. I think it's nice to keep those concepts
separate... having CONST sometimes mean the value and other times mean
the address is a bit weird. This way CONSTBUF[0] is the address of the
0th constbuf.
Yeah. I think we also may need another type for bindless as I'm planning
to use TGSI_FILE_CONSTANT for regular uniforms. The plan is to use LOAD
for supporting packed uniforms rather than padding everything to vec4.
