Subject: i965/fs: Add builder emit method taking a variable number of source registers.
X-Git-Tag: upstream/17.1.0~17351
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5a5607a16ce7bf5eace2cf4b267af304aef05e90;p=platform%2Fupstream%2Fmesa.git

i965/fs: Add builder emit method taking a variable number of source registers.

And start using it in fs_builder::LOAD_PAYLOAD().  This will be used
to emit logical send message opcodes which have an unusually large
number of arguments.
