Subject: i965: Move VS load_input handling to nir_emit_vs_intrinsic().
X-Git-Tag: upstream/17.1.0~7836
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3dba8516d6468866f2534f517358a6243eb0995e;p=platform%2Fupstream%2Fmesa.git

i965: Move VS load_input handling to nir_emit_vs_intrinsic().

TCS/TES/GS and now FS all handle these in stage-specific functions.
CS don't have inputs, so VS was the only one left using this code.

Move it to the VS-specific function for clarity.
