Subject: gallivm: Eliminate tgsi_util_get_full_src_register_sign_mode call.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e1e03ce4928edf4ea0ef43d853cb869f70b126aa;p=mesa.git

gallivm: Eliminate tgsi_util_get_full_src_register_sign_mode call.

It complicates more than it simplifies, now that there's only one negate
bit on TGSI registers.
