Subject: i965: Add a macro for accessing the SO_WRITE_OFFSET[0-3] registers.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=58765bb481636c15af2e0e92de51bbc465967c09;p=mesa.git

i965: Add a macro for accessing the SO_WRITE_OFFSET[0-3] registers.

Using a function-like macro makes it easy to loop over all four streams.
