New Revision: 46283
URL: http://llvm.org/viewvc/llvm-project?rev=46283&view=rev
Log:
Added special escape sequences "\{", "\}", and "\|" when processing
getNodeLabel(); these sequences allow the user to specify the characters '{',
'}', and '|' in the label, which facilitate breaking the label into multiple
record segments.
