Microblaze simulator - Fix missing prototype

Microblaze simulator - Fix missing prototype

[Joel Sherrill]

[-- Attachment #1: Type: text/plain, Size: 648 bytes --]

Without this patch, the Microblaze simulator generates
a missing prototype warning which is treated as an error.
I don't see this routine referenced elsewhere, so there is
the possibility that it also could be made static.  But
it definitely needs a prototype to build.

OK to apply?

     * microblaze-rom.c (_initialize_picobug_rom): Add prototype.

Eh, mismatch between ChangeLog entry and actual diff?

(a) The patch does not reflect the subject of the message, nor the
ChangeLog;

(b) I have already made comments about the message above in
http://sourceware.org/ml/gdb-patches/2012-05/msg00207.html

I suspected that and figured it was special given the odd name.

OK. I changed that.

I thought so but always feel better getting other opinions. Better
to be cautious than reverted.

Committed

Hi Joel,

Same comment from last e-mail: please send the patches to
gdb-patches@sourceware.org.  I am replying this e-mail to the
appropriate list, with comments about your patch, but please send other
patches to that list.

The `_initialize*' routines are treated specially by the Makefile, when
you build the project.  They cannot be made static because they are
called from another source file.  Take a look at gdb/Makefile.in, and
search for the rule `init.c:'.

There should be a space between the function name and the open paren.

I am not a maintainer, but this change seems pretty trivial to me so
that it can be committed without an explicit approval.

Thanks,
