Difference between infptrace and inf-ptrace

Difference between infptrace and inf-ptrace

[Markus Deuling]

Hi,

its not clear to me what the difference is between infptrace.c and inf-ptrace.[ch].

I think infptrace.c is the older one. Is it necessary to have both? Shouldn't one interface
to ptrace be sufficient?

A grep gives 25 configs using infptrace and 46 using inf-ptrace.


Regards,
Markus

Yes, infptrace.c has to die.  Don't look at it, except if you want to
convert an existing configuration to inf-ptrace.c.  Unfortunately
we're not quite there yet :(.

You're right, infptrace.c is the older one.  The interfaces are very
different - to move from one to the other you really have to be able to
test the changed config.  Your grep was a little too simple; if you
take a look at the grep results, you'll see that only a handful of
configs still use infptrace.c: alpha-osf, i386-sco, powerpc-aix,
rs6000-lynxos.  The SCO and LynxOS configurations are going to be
deleted soon but someone needs to update alpha-osf and powerpc-aix
eventually.

Thank you Mark and Daniel, I'll look at inf-ptrace then :-)

I think there are some more of these "construction areas". Is there somewhere a list of them?
What I have in mind is a kind of "project plan"? 

Maybe that would be an interesting point for the wiki for someone that has a good overview about the current work on gdb.

Markus

No, but if there were, the wiki would be the right place for them. 
There's a little bit on the wiki now, but not much.

I started a new page in the wiki and added the infptrace vs. inf-ptrace topic there.
The page is found here: http://sourceware.org/gdb/wiki/ProjectPlan

Maybe this can be the place for these "under construction" topics.

Markus
