Subject: Set up MCSchedModel after detecting the CPU type in X86SubTarget.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=bfcb4aa10b5948539f6ee59eecfe88faa9fc4e94;p=oota-llvm.git

Set up MCSchedModel after detecting the CPU type in X86SubTarget.

Corrects a problem whereby MCSchedModel was not being set up when
the CPU type was auto-detected.

Patch by Andy Zhang.
