Calling C functions

Calling C functions

[Jose Luis Ayala]

Hi,

I'm working with the arm7.cpu architecture and I've addded calls to C
functions with c-raw-call sentences. These functions have been written
into an arm7.opc file. However, recompilation of the opcodes directory
does not read this file and does not generate the resulting files.

Does arm7.opc file have to follow any prototipe? Do I have to make any
change in any Makefile?

Thanks a lot!

Jose

The bodies of functions that define c-calls go straight into the
appropriate simulator source files, and not into the .opc file.

It would probably be best to post some fragments of your .opc file, if
you can, but from memory, the .opc file must follow the name of the
arch (as defined in the cpu description), not the filename of the .cpu
file.  This is, admittedly, a bit of a gotcha.

Try renaming arm7.opc to arm.opc and regenerate--see if that helps.

It can not be that easy that Jose just forgot to configure with
--enable-cgen-maint ?  From memory, I think that must be enabled to
enable the regenerate rules in opcodes/Makefile.[am|in|]

The rules are still present in the opcodes Makefile; they just aren't
a dependency rule for `make all' which is what --enable-cgen-maint
does.
