Hello there,

I'm reaching out to know how much interest there'd be to add upstream
support in binutils for the Sony PSP CPU. Before patches are crafted and
tests are written, I'd like to know if this is something that you guys
would consider merging. I'd be doing the work but you would need to help
reviewing and merging it of course :)

The Sony PSP is a device that has a homebrew community (see
github.com/pspdev) behind and that's still alive and kicking. Although the
device is rather easy to support from a toolchain point of view (it's a
MIPS device) it features some special floating point co-processor (VFPU)
that has an interesting and rich instruction set. At the time of writing,
the toolchain is almost a vanilla gcc build (just a couple of patches) and
a rather patched binutils port. Since the VFPU instruction set is mostly
orthogonal to the MIPS instruction set, it was relatively easy to rebase
over the years. A few years ago a rewrite of the MIPS backend in binutils
meant the community was stuck on an older binutils release, which required
a full from scratch rewrite. This is why we think it'd be a great idea to
upstream this code so that it can live on.

Thanks for you time and help!

David

Of course. :-)

The short answer is "yes", but with a caveat.  Or two.  The first being that
someone needs to volunteer to act as a maintainer for the port.  They need
to be willing to read the mailing list, handle PSP specific bug reports,
answer questions about the port, and generally make sure that it carries on
working as the years progress.

The other caveat is that ideally the copyright for the patches should be
assigned to the FSF.  (Strictly speaking we are now accepting DCO signed
contributions as well, but for a new port I would feel happier with a
copyright assignment).  Plus they should follow the GNU Coding Standards,
not break other ports, have a testsuite, and all the usual things for a
contribution to the GNU Binutils.

Cheers
   Nick

No problem with any of these things at all. I can indeed act as
mantainer of the port, shouldn't be a lot of work I think.

Although I have some idea on how I will create patches, I still have
some questions. Do you guys have some docs and guidelines on how
patches for new targets should look like? Any preferences or
guidelines to make reviews easy for you? Perhaps there's some
canonical examples you can point me to?

Thanks again, and sorry for the late response :)

David

Not yet, but I am working on it.  I have created a wiki for the GNU binutils
(https://sourceware.org/binutils/wiki/HomePage) with the intention of adding
information suit able for users and contributors to the binutils.  It is a
work in progress at the moment, but I hope that it will prove to be useful
in the long run.

> Any preferences or guidelines to make reviews easy for you? 

Off the top of my head ....

   * One patch per problem please, unless the patch is very big,
     in which case splitting it up based on top-level directory
     is usually the way to go.

   * Attached or inline patches are OK, although some people's
     mailers do tend to corrupt inline patches (by line wrapping
     them for example) so often attachments are better.

   * Use git to create the patches (or "diff -rup if the sources
     are not in a clone of the repository).

   * Include details of how you tested the patch.  If possible
     test with several different builds, in order to catch potential
     problems.  For example if you are sub,itting a PSP patch which
     also touches some generic files then testing with a toolchain
     configured for a ntive linux host would be a good idea.

Check the binutils mailing list.  It is full of them. :-)

Cheers
   Nick

Hello again Nick,

So I'm splitting the changes in 3-4,... perhaps 5 patches, since
adding proper testing takes quite a bit of space and files. It might
look something along the lines of:
- Basic CPU/arch support, make binutils aware of the target.
- Basic VFPU (COP2) support for common DPU instructions (includes
instructions, registers, immediates, etc).
- Memory VFPU instructions and offset relocs.
- Support for "instruction prefixes"
- Perhaps some config files for easy configuration.

So far I'm attaching the first patch so that you can give me some
feedback. I'd rather get feedback early to know what I'm doing wrong
:)

The patch just adds the architecture "allegrex" as a MIPS II CPU. It
configures it with the extra instructions that allegrex features (many
from MIPS32r2), drops some non-existant instructions like COP2/COP3,
and adds the target to the testsuite with some extra tests for it. The
CPU is similar to the R5900 in the sense that it only supports 32 bit
FP support (all other MIPS CPU seem to either support both 32/64 FP or
none at all). I'm a bit confused on how the R5900 handles some of it
(I'd assume that msingle-float would be mandatory if
march=r5900/allegrex is used) since it produces binaries that are
marked as "FP ABI: Hard float (double precision)" which feels wrong to
me. Same goes for mfp32/mfpxx/mfp64 flags (seems like mfpxx should
always assume 32 bits for this platforms?).

Anyway, here it goes. Hope I pressed the correct buttons!

David
