Without this change, names start with 'L' will get created as temporary symbol in MCContext::createSymbol. Some other potential prefix considered: .L, does not work for AIX, as a function start with L will end up with .L as prefix for its function entry point. ..L could work, but it does not play well with the convention on AIX that anything start with '.' are considered as entry point. L. could work, but not sure if it's safe enough, as it's possible to have suffixes like .something append to a plain L, giving L.something which is not necessarily a temporary. That's why we picked L.. for now. Differential Revision: https://reviews.llvm.org/D80831

;; Test to make sure a symbol name that starts with an 'L' could be succesfully

|
;; consumed. Note that this could fail if PrivateGlobalPrefix returns
|
|
;; 'L'/'.L' instead of 'L..' because the resulting symbol gets created as

|
;; a temporary symbol.
