From d64e0eb094a108bdcdf51328425904042aa6122b Mon Sep 17 00:00:00 2001 From: Mike Stump Date: Mon, 2 Feb 2009 22:48:49 +0000 Subject: Improve -fno-opt style option processing to not require an extra option to make the -fno- form on the option. We also document the new form in the CommandLine documentation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63559 91177308-0d34-0410-b5e6-96231b3b80d8 --- docs/CommandLine.html | 16 +++++++++++++++- 1 file changed, 15 insertions(+), 1 deletion(-) (limited to 'docs/CommandLine.html') diff --git a/docs/CommandLine.html b/docs/CommandLine.html index 97df9f787c..013ff27d19 100644 --- a/docs/CommandLine.html +++ b/docs/CommandLine.html @@ -1447,6 +1447,16 @@ unrecognized option strings to it as values instead of signaling an error.
