Subject: ir3: fix has_src() to return correctly in ir3_nir_lower_tex_prefetch
X-Git-Tag: upstream/21.2.3~6436
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=433cdd1cff28dcd33028a4b6296d9a9fc6f144ed;p=platform%2Fupstream%2Fmesa.git

ir3: fix has_src() to return correctly in ir3_nir_lower_tex_prefetch

This seems to be originally introduced from 2a0d45ae6c, and 562aaea07c
misused the method.

Fixes: 2a0d45ae6c "freedreno/ir3: Add a NIR pass to select tex instructions eligible for pre-fetch"
Fixes: 562aaea07c "freedreno/ir3: respect tex prefetch limits"
