dwarf4 allows each compiler vendor to add its own range of CC values<br>in the DW_AT_calling_convention field. this means that the vendor must<br>create its own table for mapping each used CC to a given value.<br>from a wine standpoint, the list should be rather small (stdcall,<br>fastcall...) (on top of cdecl of course) (assuming old 16bit code is<br>out of the game)<br><br>AFAIK, gcc only uses those extensions for very dedicated usage (pascal<br>compiler...). I don't see any reason why one couldn't extend gcc to do<br>it, but I cannot tell how complex it will be (and if plugins provide<br>the relevant interface to do so).<br>HTH<br>A+<br><br>2012/6/6, Roger Cruz <<a ymailto="mailto:roger_r_cruz@yahoo.com" href="mailto:roger_r_cruz@yahoo.com">roger_r_cruz@yahoo.com</a>>:<br>> Hi Eric,<br>><br>> Thanks for replying. I saw that in the DWARF spec and I was afraid that<br>> DWARF may not provide detailed Info. But I also read in the
spec that the<br>> compilers use a DWARF extension feature to convey additional info such as<br>> calling convention for each routine. Is there a way to coax GCC to output<br>> that information? Maybe thru a target plugin?<br><br>-- <br>Eric Pouech<br><br><br> </div> </div> </div></body></html>
