llvm dev - Sep 2006 - [LLVMdev] #line directives in llvm-gcc

Hi!

Apparently llvm-gcc ignores #line directives in source files when generating
debug information. When I compile this:

//test
int f(int a)
{
#line 1 "someplace"
   return a*a;
}
//end

with `llvm -g -S lines.c`, `someplace' is not mentioned in lines.s. It also
looks like functions #included from header files get attributed to the
#including file (albeit at the right line number).

Is there an option to take #line into account that I am missing?

Thanks in advance,
Yossi

Would you please file a bug in bugzilla http://llvm.org/bugs/ so we  
can track this issue?  Would you also attach the test file, the llvm- 
ggc output and the equivalent output from gcc?  Thank you.

Cheers,

-- Jim
