Subject: [MISched] Explanatory error message when machine model is not complete. NFC
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=9ec3763313ac986bab8414f16267605c9ab28b64;p=oota-llvm.git

[MISched] Explanatory error message when machine model is not complete. NFC

When not all instructions have a scheduling class,
the error message now provides a possible solution.
