Subject: swr: Align query results allocation
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=00847e4f14dd237dfcdb2c3d15be1325a08ccf5a;p=mesa.git

swr: Align query results allocation

Some query results struct contents are declared as cache line aligned.
Use aligned malloc, and align the whole struct, to be safe.

Fixes crash when compiling with clang.
