Subject: mesa/compiler: add stage to shader_info
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0de6f6223ab917ec532e3fe3afd14f8f5cd3b87b;p=mesa.git

mesa/compiler: add stage to shader_info

This will allow us to simplify the current program logic for SSO.

Also since we aim to detach shader_info from nir_shader this will come
in handy avoiding passing nir_shader around just to keep track of
the stage we are dealing with.

V2: set stage for arb asm programs also.
