Always use TSO, per the Oracle 2015 manual.
This is slightly less restrictive than the TCG_MO_ALL default,
and happens to match the i386 model, which will eliminate a few
extra barriers on that host.

This will be of small comfort to sparc64, because both
sun4u and sun4v board models force max_cpus = 1.
But it does enable actual smp for sparc32 sun4m.

The oldest supported cpu is the microsparc 1;
all other cpus use CPU_DEFAULT_FEATURES.
Remove all bits that are always set: FLOAT, SWAP, MUL, DIV,
FLUSH, FSQRT, FMUL.

I've just found the command-line properties that could affect these, which unfortunately
don't use the CPU_FEATURE_* symbols and hard-code bit numbers.
I'd be tempted to remove the properties as well, with the possible exception of
CPU_FEATURE_FLOAT, but maybe not even that.
Thoughts?

Do we have a convention, when do we use "-" and when "."?
I plan to add a few instructions which do something with special
registers on OpenSparc, but would be nop in QEMU. Shall I use dots? Or
rather dashes?

Dots are decoded by something (@format, %field, etc).
Dashes are completely ignored.
See "fixedbit_elt" in docs/devel/decodetree.rst.

That depends on what it is.

From: Richard Henderson @ 2023-10-13 21:28 UTC (permalink / raw)
To: qemu-devel; +Cc: mark.cave-ayland, atar4qemu
As an intermediate step in decodetree conversion, create
new functions passing in DisasASI and not insn.

Oh wow, that's amazing - looking into this has been on my TODO list for quite some
time now :O
FWIW I'm still struggling with hangs on sun4m which I've noticed a lot more whilst
working on my ESP changes. I *think* it is the same issue I saw before when testing
your original gen_helper_lookup_tb_ptr() conversion series for target/sparc, which
did disappear in the final version of the series but I can now reproduce fairly
consistently with git master.
The reproducer here is easy with Solaris 8:
./build/qemu-system-sparc -cdrom sol8-cd1.iso -boot d
Then when the splash screen appears keep wiggling the mouse until everything locks
up. In my ESP traces I sometimes see random hangs where the trace-events would end
with "esp_raise_irq()" and sit there for 10s of seconds before resuming, so both of
this seems to suggest that interrupts aren't getting through when they should.
Anyhow I can certainly give this series a spin on my OpenBIOS test images over the
next few days as time allows.
ATB,
Mark.

Hi Richard,
I've had a chance to run this through the 32-bit set of my SPARC OpenBIOS tests and
have found a few regressions summarised below by commit:

I hope this is enough to be going on with for now: once the 32-bit SPARC tests pass I
can look at running through the longer set of 64-bit SPARC tests.
ATB,
Mark.

Incorrectly translated "call %o7".
Old decoder always computed the source into a temp; new decoder tries to use cpu_gpr[]
directly. Clobbered %o7 with return address before setting npc. Fixed by moving the
return address store later.
