[PATCH] D79778: [CodeGen] Remove buggy handling of input operands in inline asm

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Oh, hmm, somehow I missed that when I looked at this before; gcc actually tracks whether the variable is initialized/assigned-to, and doesn't emit an error if there is no assignment.  And, as usual with gcc, whether the error is emitted depends on the optimization level in some cases.  That seems completely bizarre, but okay, I guess.

If there's some real code depending on that, sure, we can temporarily revert the relevant LLVM changes.
