Subject: When extending the lifetime of a temporary, make sure to emit a branch to the cleanup... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=6ec687d2ad8b4968675f7baec15ba302b4d7e199;p=clang

When extending the lifetime of a temporary, make sure to emit a branch to the cleanup exit block. This fixes a broken module error in LLVMCConfigurationEmitter.cpp.
