Subject: Debug Info: Remove unused code. The MInsn of an _abstract_ variable is
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1d7b7c5ba04ac6f6eecf12192816e14ba2850099;p=llvm

never used again and updating the abstract variable for each inlined
instance of it was questionable in the first place.
