Re: cross gcc 4.0.2 question

[Jan Capek <jen at jikos dot cz>]

Hi Ian,

thanks for reply. I think I have tried the -E option at first to see what 
the sources looked after the preprocessing step, cuz I was suspecting 
some 'void' macro breaking things, however that didn't happen.. The 
--save-temps gave me the same result. Below is the relevant part of 
the libgcc2.i file.

I am wondering if some of the 'define_insn "jump"' or 'define_insn 
"indirect_jump"' definitions in the .md file would be responsible for this 
behavior. I am really new to all this, so I need to study a few papers 
that I found on the web about gcc porting. Before I can make any rough 
guess of what is going on.

Still any input on what to look at in the .md file is very welcome.

Jan

This is the output after preprocessing:
