Subject: A couple minor fixes to make debug info usable for arbitrary code: don't
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=32ea35fee916ed73fe343bad2de9a609eb2cca38;p=clang

A couple minor fixes to make debug info usable for arbitrary code: don't
emit incomplete types, because they crash llc, and always use the
logical location as the current location so we don't crash doing invalid
queries on CurLoc.
