From https://developer.arm.com/documentation/den0024/a/Introduction?lang=en

"AArch64 is the name used to describe the 64-bit execution state
of the ARMv8 architecture. AArch32 describes the 32-bit execution
state of the ARMv8 architecture, which is almost identical to ARMv7.
GNU and Linux documentation (except for Redhat and Fedora distributions)
sometimes refers to AArch64 as ARM64."

I would agree that you could use the therm ARM64 as a synonym of
Aarch64, but giving me just that response... It isn't even funny.

Since Charles wrote the arm64 compiler, he can call it whatever he wants.

The compiler appears to be called 7c.

I wasn't talking about any compiler. Yes, you can call your compiler
whatever you want. You can call it shitarm, just don't tell me that
the 64-bit Armv8-A architecture is called that (well, if you were
used to programming in A32 assembly and now you have to do it in
A64, I think you could call it _that_).

Choosing $objtype (and $O, etc) is the first thing someone writing
a new Plan 9 compiler port does. These values are set in libmach.
I suggest reading the 2c(1) manual page, as well as the Plan 9
compiler papers which explain how the Plan 9 compiler works.

With this new information you will know what even if you didn't
think you were talking about the compiler, you were actually talking
about decisions made in the compiler when you were asking about
Plan 9 on some architecture or another.

It is fine if you do not agree with these decisions.

Arm isn't sending you a gift basket of shitty arm computers for
defending their ip. Besides, arm64 is perfectly descriptive vs. Arm's
confusing nomenclature which is just a lazy copy of Intel's iaXX
nomenclature.

There is no 7c on labs' , there is no patch for aarch64, arm64 or
whatever you want to call it in 9legacy. There is no kernel for
any aarch64 machine on labs/legacy. Seriously, what is so hard to
understand in this frase:

Perhaps you should fork 9legacy and rename $objtype to aarch64.

What on Earth are you talking about? The name of the architecure,
that was the subject of the two little messages I exchanged with
Charles, do you really think that when I said AArch64 I was reffering
to the name choosen for plan9 (9front?, there is no AArch64 support
in labs|9legacy) port?

Again, what on Earth are you talking about?, A simple question, so
bloody simple and again as usual the same... you know what, just
forget it, please, everyone, just forget it.

To answer your original question, no: there is no aarch64 support in either
9legacy or the Bell Labs distribution.

I just ported 7c, 7l and 7a from 9front. I'm adjusting libmach,
mkfiles, etc. Porting 9front's aarch64 raspberry pi kernel can be
an oportunity to learn about the kernel design.

Correct me if I'm wrong, but Richard's kernel is 32-bit (Aarch32) only,
though with the PAE stuff enabled to access more than 4GiB of _physical_
memory. The virtual address space is still limited to 4GiB.

You enquired about support for an architecture within Plan 9 on a Plan 9

string to help you locate it, but get a little lecture about Arm's naming
scheme (come to think of it, what are Thumb-1 and Thumb-2 called?). Next

Has someone done something with aarch64 on labs|9legacy?
It's called arm64

Great.

Because with this 4 magical words I was supposed to find... what?
Where? What are you talking about? Where is this work on Bell Labs'
plan9 that I could find using the string "arm64" (which of course
I knew already from 9front, the only distribution with aarch64
support)? Even in Inferno there is no aarch64 support. Where are
this people publishing aarch64 work in the labs distribution that
I could fing using "arm64"? What are you talking about?

But now after all the useful interesting contribution to the list,
as usual, you have time to even express sarcasm.

You haven't help me to find anything, you don't have to do it, of
course, but then don't talk like you have done it.

A simple question, a fucking simple question and here we go with
the trolling and the bullshit, I'm done with this fucking list.

I've known and observed Charles for a very long time, indeed. I can imagine
how you interpreted what he wrote as you have, but perhaps consider that he
didn't mean what he wrote in the way you have taken it.

it's just that you don't like what you found. he helped by making sure
there would be a compiler.

you don't like the compiler because it has the wrong brandname
attached to it, and the wrong people are playing with it, am i right?

I'm sorry that my original terse reply, which was well meant, stirred up a

I simply didn't know that it wasn't to be found in the two
distributions you mentioned
(I did know it was certainly in 9front).
