Subject: ir_to_mesa: Actually initialize the undef register for scalar_op1.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=59a23d7fb93603b2449db4c5d786934a07aebfcb;p=mesa.git

ir_to_mesa: Actually initialize the undef register for scalar_op1.

Fixes glsl-sin, glsl-cos on 965, where we rely on unused src arguments
in the VS having a file of PROGRAM_UNDEFINED.
