New Revision: 92809
URL: http://llvm.org/viewvc/llvm-project?rev=92809&view=rev
Log:
Per offline discussion with Doug, don't perform typo correction when we have
encountered a fatal error. On some files that are woefully wrong (missing
headers) this can cause a 3x slowdown in some cases when parsing the file. It
makes sense not to perform typo correction in this case because after a fatal
error diagnostics will either be suppressed or not really make any sense.
