Subject: gallium/util: Don't implement u_bit_scan64 on MSVC.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=661c8bb220faf6f7c2f065eec515cedfa8d5f8da;p=mesa.git

gallium/util: Don't implement u_bit_scan64 on MSVC.

As ffsll doesn't exist in MSVC yet, and u_bit_scan64 is only used by
radeonsi which is never built with MSVC.

This is just a stop-gap fix to unbreak MSVC build until we refactor these
mathematical portability wrappers into src/util.

Trivial.
