From 929fccd4761b3de9d6c651cc85799d4bbfd165b0 Mon Sep 17 00:00:00 2001 From: "Michael J. Spencer" Date: Mon, 22 Oct 2012 22:13:48 +0000 Subject: [Options] Add prefixes to options. Each option has a set of prefixes. When matching an argument such as -funroll-loops. First the leading - is removed as it is a prefix. Then a lower_bound search for "funroll-loops" is done against the option table by option name. From there each option prefix + option name combination is tested against the argument. This allows us to support Microsoft style options where both / and - are valid prefixes. It also simplifies the cases we already have where options come in both - and -- forms. Almost every option for gnu-ld happens to have this form. llvm-svn: 166444 --- clang/lib/Frontend/CompilerInvocation.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'clang/lib/Frontend/CompilerInvocation.cpp') diff --git a/clang/lib/Frontend/CompilerInvocation.cpp b/clang/lib/Frontend/CompilerInvocation.cpp index 4f0cfa80019..1de547d9b40 100644 --- a/clang/lib/Frontend/CompilerInvocation.cpp +++ b/clang/lib/Frontend/CompilerInvocation.cpp @@ -1001,10 +1001,10 @@ static void addWarningArgs(ArgList &Args, std::vector &Warnings) { for (arg_iterator I = Args.filtered_begin(OPT_W_Group), E = Args.filtered_end(); I != E; ++I) { Arg *A = *I; - // If the argument is a pure flag, add its name (minus the "-W" at the beginning) + // If the argument is a pure flag, add its name (minus the "W" at the beginning) // to the warning list.
