[LLVMdev] Can the FileCheck ignore spaces ?
Shawn
I'm writing testcase for the MC layer regression in llvm, the
disassembled string is a bit complicate, for example:
"IALU.T0 (I0) = BIU0.DM ; REPEAT AT ( 2 ) ;;"
The spaces in the disassembled string is error-prone. Is there any
option to tell the FileCheck utility to ignore the spaces ?
Kind Regards.
Shawn.

says FileCheck ignores white spaces/tabs by default unless you use
"--strict-whitespace" option.

- "--strict-whitespace
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 argument 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 .

I guess a whitespace means a space or a tab. Filecheck treats tabs and
spaces equally, and ignores differences between "whitespace" strings.
