Subject: softpipe: Enable PIPE_CAP_TGSI_ANY_REG_AS_ADDRESS;
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ba22f014f9db1852e6336485de4b9936edc6106c;p=mesa.git

softpipe: Enable PIPE_CAP_TGSI_ANY_REG_AS_ADDRESS;

tgsi_exec.c uses the generic src load path for indirects, so we don't
actually need addr regs.  Saves extra intructions.

shader-db results:
total instructions in shared programs: 3346685 -> 3249052 (-2.92%)
instructions in affected programs: 961832 -> 864199 (-10.15%)
