From: Vadim Girlin Date: Wed, 24 Aug 2011 20:32:55 +0000 (+0400) Subject: r600g: fix replace_gpr_with_pv_ps X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fdb62ef3f5b0fadd3cbac610f5b612bcfad5af1a;p=mesa.git r600g: fix replace_gpr_with_pv_ps Instructions with 3 source operands have no write mask, so we may replace their destinations with PV/PS in the next group even if their dst.write is 0. Note: This is a candidate for the 7.11 branch.
