Subject: Add 'remark' diagnostic type in LLVM
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=72c42d93416b9aac1750389a862d569948612c53;p=oota-llvm.git

Add 'remark' diagnostic type in LLVM

A 'remark' is information that is not an error or a warning, but rather some
additional information provided to the user. In contrast to a 'note' a 'remark'
is an independent diagnostic, whereas a 'note' always depends on another
diagnostic.

A typical use case for remark nodes is information provided to the user, e.g.
information provided by the vectorizer about loops that have been vectorized.
