[Lldb-commits] [PATCH] D62759: Fix lit tests on Windows related to CR

[Adrian McCarthy via Phabricator via lldb-commits]

amccarth created this revision.
amccarth added a reviewer: jasonmolenda.

Problem discovered in the breakpoint lit test, but probably exists in others.

lldb-test splits lines on LF.  Input files that are CR+LF separated (as is 
common on Windows) then resulted in commands being sent to LLDB that ended in 
CR, which confused the command interpreter.

This could be fixed at different levels:

1. Treat '\r' like a tab or space in the argument splitter.

2. Fix the line splitters (plural) in lldb-test.

3. Normalize the test files to LF only.

If we did only 3, I'd expect similar problems to recur, so this patch does 1 
and 2.  I may also do 3 in a separate patch later, but that's tricky because I 
believe we have some input files that MUST use CR+LF.
