[LLVMdev] Can the FileCheck ignore spaces ?

By default, FileCheck canonicalizes input horizontal whitespace (spaces 
and tabs) which causes it to ignore these differences (a space will 
match a tab). The/--strict-whitespace/ 
disables this behavior. End-of-line sequences are canonicalized to 
UNIX-style ‘n’ in all modes."

So it just ignore the differences between space and tab, not the 
whitespace .
