Subject: Correctly handle multi-lined RUN lines.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1470f5b2ad8e873be6cfef72f00162b3b437aa65;p=llvm

Correctly handle multi-lined RUN lines.

`utils/update_{llc_test,test}_checks` ought to be able to handle RUN commands
that span multiple lines, as shown in the example at
http://llvm.org/docs/CommandGuide/FileCheck.html#the-filecheck-check-prefix-option
