Hi Ian, So far, we've only been able to deduce that functions in gcc/config/i386/i386.c merely check for conflicting attributes (e.g. fastcall AND cdecl, fastcall AND regparam, etc.) in functions like ix86_handle_cconv_attribute. Is there a specific suite of functions we should be looking at? (i.e., ix86_xxx_foo_yyy) Thanks, - Robert On Mon, Mar 14, 2011 at 11:58 AM, Ian Lance Taylor <iant@xxxxxxxxxx> wrote: > Robert Butler <lighth7015@xxxxxxxxx> writes: > >> Can anybody please help us locate where exactly in gcc-trunk's >> sourcecode the implementations of these conventions would be >> located? > > gcc/config/i386/i386.c.
