Subject: tgsi/exec: initialise SysSemanticToIndex array to -1
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f78bcb7638be3c2612fd1ab0371361a8b53104c7;p=mesa.git

tgsi/exec: initialise SysSemanticToIndex array to -1

We want to use the SysSemanticToIndex to tell if we've seen
the semantics at all.
