llvm dev - Feb 2012 - [LLVMdev] How To Pass An Command Line Option To The Pass

Hi all,

I have a problem with passing multiple option(-flag=aaa/bbb) from clang to llvm,
I don't know how to parse it, should I parse it in clang and pass it
to llvm or should I parse it in llvm pass where I use it,
could you help me.

Thanks in advance,
Sevak.

Hi Sevak,

You can use the cl::opt<> template to declare your options inside your
LLVM
pass. When calling clang, you can then pass options using -mllvm (e.g.
clang -mllvm -my-option=1).

Hi all,
I have problem with debugging clang, gdb does not stop in function
ParseFrontendArgs, the function works because I wrote errs() and I saw
it in command line,
I also wrote __asm__("int $3") in  ParseFrontendArgs but it does not
help.

Thanks in advance.

Are you debugging the correct process?  Note that invocations of 'clang'
without '-cc1' fork/exec 'clang -cc1' to handle front end
options.
