Subject: llvmpipe: make texture buffer offset alignment == 16
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7cac880831b21d2fcddf6477518a458dca9fc217;p=mesa.git

llvmpipe: make texture buffer offset alignment == 16

Due to use vmovdqa instructions in the asm, which require 16-byte
aligned buffers.

This fixes a crash in
KHR-GLES31.core.texture_buffer.texture_buffer_texture_buffer_range
