Hardly anyone hand-codes significant amounts of assembler on any
architecture these days.  It's either an exercise or
recreation/masochism, and in either case the relative difficulty of
coding for architecture X vs Y doesn't matter much, within reason and if
you're not too concerned about micro-optimization.  In the case of
jonesforth, the end result will be interesting since people will be able
to run it on arm-based computers.

There are some other significant architectures of interest, and maybe
more will emerge.  Overall some kind of abstract assembler approach has
its attractions.

It doesn't really matter much to an experienced assembly language
programmer.  But, to a bunch of students, many of whom might be
learning how logical AND, OR, NOR or basic two's complement
arithmetic works for the very first time, it's probably a
nightmare.  They've got to learn *two* different assembly languages
from big thick obfuscated programming text books.  They've also
have to learn GNU AS Motorola/AT&T syntax and GAS directives.  Is
GAS being used on the ARM side too or do they have to use another
assembler?  How many different x86 instructions does Jonesforth
use?  Are there endian-ness issues too?

lol.

That's why I thought HLA could be a good solution for this. Nobody is saying
yourforth must be written in assembly only that assembly is the best way to
present it. HLA might be even better.

> They've also have to learn GNU AS Motorola/AT&T syntax and GAS directives.

Depends which assembler they use. You don't have to use more than one if you
don't want to. gas supports a quasi Intel syntax now for some time.

> assembler? 

There are a quite a number of vendor toolchains on ARM, some based on gcc
some homegrown. The answer to your question is wherever gcc is, gas is there
also since it's how gcc C code gets assembled. gas syntax is as consistent
as possible across the dozens of targets since it was designed as a back
end for gcc not something for people to code in.

Most assembly programmers on Usenet consider Randall Hyde's HLA to
be a high level language more similar to Pascal than assembly, with
some cruft from other languages like C and Fortran tossed in, and a
bit of easily inline-able assembly too.  They and I don't consider
it to be assembly language.

Heavens above, I cannot even begin to tell you how wrong this is.
I've spent months of the last year or so writing a vast amount of
ARM64 assembly language (See here for details of my day job:
http://mail.openjdk.java.net/pipermail/hotspot-dev/2013-July/010181.html)
The reason?  If you want a world-class high-performance virtual
machine, hand-coded assembly language is still unbeatable.

These are good choices. I agree Linux is the obvious target for such a
project since people who write code overwhelmingly use Linux on x86 these
days and I said so earlier. Reading Randy Hyde's comments in his HLA
Reference manual starting around 1.7 I wonder if HLA might be a better
choice than fasm since the yourforth project is targeted at beginners and
focused on clear presentation. Professor Hyde's experience was people with
HLL programming experience (Pascal, C, C++, etc.) were able to "get their
heads around the HLA code" much faster than when he used to teach with
MASM. I like fasm because it's elemental and lets you produce an executable
in one go, but hla does that also. I can see  where fasm ought to be very
appealing to Forthers but beginners using this project aren't likely to be
aware of the beauty of a partially self-hosted Forth hosted in a fully
self-hosting assembler ;-)

Hyde does argue rather pursuasively for his approach and has the rubber
meets the road experience to be able to say it. If one doesn't get too
sidetracked by personal feelings on what an assembler out to be and just
wants a low-level language that also happens to present things in a way many
people are used to viewing them the idea would seem to be very practical for
this project, almost perfect really.

However HLA will make porting yourforth to non-x86 targets much harder than
using g(h)as(tly) or even fasm on Linux but again not many people have the
other targets listed who don't also have an x86 desktop computer.

Thanks to everyone carrying on with this idea. I'm excited about seeing what
you come up with.

There will be persuasive arguments in the source addressing why it is done
the way it is done, including the choice of fasm.

jonesforth is about leaving out layers. assembler is a layer but thank
<theity> there is only the Forth layer above it. HLA needs a "true assembler"
layer below HLA, that is not under control. So it is a bit against the
teaching purpose.

I've some experience with porting using a similar model. As Elizabeth
Rather has pointed out at occasion too, differences between OS-es count
for at least as much effort as between assembly languages

That was true of V1 which was really more of a preprocessor. V2 of HLA is a
real assembler and emits elf object directly. It only needs a linker. It has
the options to produce fasm nasm or masm output usable on windows or gas
output for Linux. The default on Linux is to produce and ELF object.

Yes quite so.

Thanks,

That sounds much more viable than I expected, but still.
The use of fasm amounts to
    fasm yourforth.asm
and 3 lines in the source:
    "create an elf executable"
    "this is 32 bits code"
    "one segment. Allow read write execute"
One segment (no bits/no-bits). No linker.
No installation. One address in the elf header to patch to go from 1M to 3G.
That is hard to beat. No, that is impossible to beat.

yourforth is simple enough though that if you're already familiar
with hla that using hla will be easy.

Yes, I know. I believe I mentioned earlier I feel fasm is a great choice.
It was specifically the ability to create an elf executable directly from fasm
that I thought it was a great choice. Looks like we're on the same page.

I'm not familiar with HLA except from looking over the doc for an unrelated project awhile
ago. It would seem people familiar with higher level languages like Pascal, C, or C++ (and
I think Java and really all the C-derived languages) would find HLA more approachable than
other assemblers, and isn't the point as you said to have as little get in the way as possible
while still implementing a viable Forth? There are two ways to look at little getting in the
way- one is technical and the other is pedagogy. On the pedagogy side Hyde does a convincing
job of explaining the benefits of HLA with actual student experience. He seems to be a good teacher. 

Anyway, sounds good!

Bill

I agree with this. You have no idea how much!

But I should have written before HLA does help tremendously in this
situation. If you use his extensive stdlib you can write *cross platform
assembly code* that will actually run on Linux, Windows, FreeBSD, and MacOS
without *any* source changes. It's really a remarkable accomplishment and
possibly a good alternative to C and inline assembly for several types of
applications. Perhaps yourforth is one of them.

I think the next step after FASM should be a self-hosted assembler
written in Forth.  This is very traditional.

What do you mean by self-hosted, a regular Forth source containing
an assembler?

Yes.  Assemblers written in Forth are shockingly simple.  I'm sure
you're familiar with them.

Another thought is to use the same assembler mnemonics across multiple
architectures and program the Forth primitives in the subset shared by
the machines of interest, sort of like MINIMAL (from Spitbol) that we
discussed a while back.  So MOVTW would be a mnemonic for copying the
TOS to the working register, that would assemble as the appropriate
machine instruction for the processor at hand.  I think this kind of
thing has been done before too.

Sure.
An Pentium assembler is in the examples. The effort here is not writing
the assembler but installing and running the comprehensive test from
ciasdis.

I've had the opportunity to do that, and I didn't. The i86 Forth's
are generated from one source and I've m4 file with macro's like
define({SI},{ESI})
define({SI},{%ESI})
define({SI},{RSI})
define({LODS},{LODSL})
The first version of yourforth.fas and its documentation are generated
from this common source, but there it stops for me.

What you propose is over the top, IMO.

You know how many (engineering) students I have that hardly
know what Linux means, let alone use it? Our students get a
laptop from the university, and it runs Windows.
Learn to use MinGW64 and breed some future Fidels.
