Please check out the second revision of the patches. I addressed all the
comments in the review and ran the testsuite. There's some tests failing
due to other changes unrelated to these patches.
David Guillen Fandos (3):
Add MIPS Allegrex CPU as a MIPS2-based CPU
Add rotation instructions to MIPS Allegrex CPU
Add additional missing Allegrex CPU instructions

The Allegrex CPU was created by Sony Interactive Entertainment to power
their portable console, the PlayStation Portable.
The pspdev organization maintains all sorts of tools to create software
for said device including documentation.

The Allegrex CPU supports bit rotation instructions as described in the
MIPS32 release 2 CPU (even though it is a MIPS-2 based CPU).

Allegrex supports some MIPS32 and MIPS32r2 instructions (albeit with
some encoding differences) such as bit manipulation (ins/ext) and MLA
(madd/msub). It also features some new instructions like wsbw and
min/max or device-specific ones such as mfic.

I have still noticed a couple of minor issues as follows.

I have reformatted this to follow the GNU Coding Standards (which require
operators to put on the subsequent line when wrapping), and also replaced
the separating space with a tab and aligned backslashes for consistency
with the rest of this file. I have also removed extraneous parentheses (I
haven't flagged it before, but let's do it while redoing this macro
anyway). Last but not least I used my discretion to swap CPU_ALLEGREX
with CPU_R5900 for consistency:
#define CPU_HAS_LDC1_SDC1(CPU) (mips_opts.isa != ISA_MIPS1 \
&& (CPU) != CPU_ALLEGREX \
&& (CPU) != CPU_R5900)

I have removed an extraneous tab that caused visible column misalignment,
which wasn't here in v1, hmm, and also fixed the order for `singlefloat':
mips_arch_create allegrex 32 mips2 { singlefloat oddspreg } \
{ -march=allegrex -mtune=allegrex } \
{ -mmips:allegrex }
While at it I noticed the documentation for `singlefloat' isn't correct
(it never was in the first place, but it's even less so now with Allegrex
support added), so I have folded an obvious fix into your change.

This still overruns 79 columns. I have fixed this thus:
run_dump_test_arches "no-odd-spreg" "-mfpxx" \
[mips_arch_list_matching mips2 !r5900 !allegrex]
(and for consistency did the same with the change above; I'll fix other
mess around here with a separate change).
I have now committed this change, with the amendments mentioned. Thank
you for your contribution.

Just a minor nit about this version.

You haven't reordered `ror' here as requested with v1. I have done this
for you (and fixed the order for `singlefloat' in 1/3 too, which I missed
previously), but please be more careful in the future. It helps when the
reviewer doesn't have to double-check everything.
I have now committed this change with said modification applied. Thank
you for your contribution.

And I have committed this change too. Thank you for your contribution.
