Subject: gallivm: Fix lp_build_sgn for normalized/fixed-point integers.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9fb4eef6a159fb5af97694b15a5f9b5998e9f6e5;p=mesa.git

gallivm: Fix lp_build_sgn for normalized/fixed-point integers.

These types got broken with the recent commit that fixed lp_build_sgn
for negative integers.
