[PATCH] D143305: [clang] Fix -Xarch_ for -mllvm and alike

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added a comment.

An option value treating a space differently (as a delimiter in this case) is uncommon. I suggest an alias `-mllvm=` (D143325 <https://reviews.llvm.org/D143325>) which is more inline with the convention of the majority of options that take a value (`=` instead of ` `).
