Report unrecognized arguments before reporting argument incompatibility #211

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. touch ~/Desktop/empty.cpp
2. $HOME/llvm/build/Release+Asserts/bin/clang++ -fsanitize=undefined 
-fnosanitize=vptr -fno-rtti ~/Desktop/empty.cpp

What is the expected output? What do you see instead?

Expected:

clang: warning: argument unused during compilation: '-fnosanitize=vptr'
clang: error: invalid argument '-fsanitize=vptr' not allowed with '-fno-rtti'

What I got:

Only the error.  As a result, I didn't realize I had left out a hyphen in the 
no-sanitize argument, and thought something was broken.

What version of the product are you using? On what operating system?

LLVM r186884 on Mac OS X 10.8.x
