Subject: i965/fs: Do not mark used surfaces in FS_OPCODE_GET_BUFFER_SIZE
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=eea3c907cc480a105224b21be51d62bc64ea1057;p=mesa.git

i965/fs: Do not mark used surfaces in FS_OPCODE_GET_BUFFER_SIZE

Do it in the visitor, like we do for other opcodes.

v2: use const, get rid of useless surf_index temporary (Curro)
