llvm dev - Jan 2009 - [LLVMdev] llvm/llvm-gcc-4.2 svn still produces -Wformat/-Wformat-security

The current llvm/llvm-gcc-4.2 svn when built on
i686-apple-darwin9 still produces the bogus warnings...

f951: warning: command line option "-Wformat" is valid for
C/C++/ObjC/ObjC++ but not for Fortran
f951: warning: command line option "-Wformat-security" is valid for
C/C++/ObjC/ObjC++ but not for Fortran

whenc compling any code with gfortran. This causes the gfortran testsuite
in gcc-4.2 to fail any test for compilation errors. Can we get this fixed
before the llvm 2.5 release?

Hi Jack,

Could you craft a patch for this? Not many of us compile gfortran on  
our boxes.

The intention is to have fortran frontend built by default for LLVM
2.5+ (on darwin). And this apple-local problem seems to be the only
show-stopper.

It's very easy to build (just add fortran to the list of languages), so...
why not?  This would help catch changes that break non-C languages (these
seem to happen at every sync with Apple...).

Ciao,

Duncan.

Hi Jack,

Because of the new changes and the fact that we have only 2 days
before branching for 2.5, please retest the Fortran front end as soon
as you can to see if the problem has been resolved.

Thanks!

Hi Bill. Thanks for working on this!

Unfortunately, I'm getting this warning now:

   $ llvm-g++ helloworld.c
   cc1plus: warning: -Wformat-security ignored without -Wformat

I think you can fix it by applying the same #define trick to 
-Wformat-security that you did to -Wformat.
