Subject: [asan] insert crash basic blocks inline as opposed to inserting them at the end of... 
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=e60da02281d9de3aec4b22924b6cf1bd1a83af0c;p=oota-llvm.git

[asan] insert crash basic blocks inline as opposed to inserting them at the end of the function. This doesn't seem to fix or break anything, but is considered to be more friendly to downstream passes (test change)
