debugging gcc/cc1

[Johnny Huynh]

This must have been asked before, but my google and mailing list searches
havent gotten me anything too useful...

I have written an extra pass that is causes a seg fault in my gcc
cross-compiler, but no core file is generated (presumably from the sig
handler) and I don't know how to attach gdb to my cross-compiler.

I've tried using the output provided by "gcc -v -save-temps ..." and then
invoke cc1 from inside gdb, but thats not immediately working, and its
a pain to have to copy and paste huge chunks of text everytime I want to
trace my new changes.

tips on how to disable the sig handler (to get a core file) or trace my
new changes (preferred) would be appreciated.

Thanks,
Johnny
