[OpenSmalltalk/opensmalltalk-vm] POWER (ppc64le) port. (#493)

It would be great if there is also ppc64le/power platform supported.

And which operating system?

This is per se a good idea.
Alas, as the other comments succinctly point out, we have limited resources in the community.
This means we have neither hardware nor people nor enought knowledge (yet) to pursue that.

If we ever manage to move the target-agnostic JIT over to OSTVM, that would give us PPC for free. As to the stack interpreter, it should work as is. I haven't tried with PPC (hmmm... would be a good idea) but last November at Smalltalks I tried on RISC-V 64-bit and it works fine (I demoed it on an Unleashed board)

Well, I'm on linux ppc64le here. When I tried to

cmake .
make

it fails with:

Try forcing $PLATFORMLIBDIR in /home/karel/vcs/opensmalltalk-vm/build/vmmaker/pharo-vm/pharo, based on LIBC_SO.

  System seems to be 64 bit. You may need to (re)install the 32-bit libraries.

Also it looks like build downloads some libraries (binaries) and they are AMD64 version instead of PPC64le:

So there is something to do on PPC64le support.
Anyway, I'm surprised the beast running fine on RISC-V. If this is the case, then perhaps I'm just missing some configuration/cmake option to make that working on PPC64le too?

For folks interested in POWER architecture development/porting, the most easy way to get access to actual hardware is GCC compile farm: https://cfarm.tetaneutral.net/ -- where people working on open-source/free-software may request account and access machines from the list. POWER is presented with both big and little endian and with power7, power8 and power9 CPUs hosts and with Linux and AIX. So the coverage is quite good...

I've also tested

cmake -DFLAVOUR=StackVM .

but this still shows the problem above.

Sorry, this is not the build process used in this repo. I cannot really help with the problems you are presenting :/
Have you tried following the instructions in the README?

Tobias, indeed, I've completely messed up with this. Anyway, bear with me, testing this repo source code now.

Reading README reveals that there is obviously not build.linux64ppc64le directory with the required infrastructure. But most close is probably build.linux64x64 so I give a try to it to find out how far I can get. The first issue is that the project config.guess file is out-dated. Note, I'm using squeak.stack.spur as I've thought this is stack based VM without any JIT. Anyway, the output is here:

karel@power:~/vcs/OpenSmalltalk/opensmalltalk-vm/build.linux64x64/squeak.stack.spur/build$ ./mvm 
clean? yes

karel@power:~/vcs/OpenSmalltalk/opensmalltalk-vm/build.linux64x64/squeak.stack.spur/build$

which looks like is caused by missing clang on my box, I've installed Ubuntu 18.04 LTS clang (6.0 version) and run again. Configure part complains with one error:

and compilation part fails with a lot of errors about VM_LABEL missing:

Anyway, I hope I've followed the right project and the right README here just to point few issues you probably already know about w.r.t. PPC64le platform support. Thanks!

Thanks, this puts things into perstpective.

That config.guess is outdated might be the case, I have no Idea how that is cenerated.

For the VM_LABEL, could you try defining it to

# define VM_LABEL(foo) ((void)0)

as is done later in the file?

Perhaps you could try with gcc to check if it is the compiler choice
that is triggering errors. See below

VM_LABEL macro definition in picked up from the file:
----- platforms/unix/vm/sqPlatformSpecific.h
108 #if defined(__GNUC__)
109 # if !defined(VM_LABEL)
110 #       define VM_LABEL(foo) asm("\n.globl L" #foo "\nL" #foo ":")
111 # endif
-----

How did the __GNUC__ get defined in your compilation?

You could try passing -D'VM_LABEL(foo)=0' while compiling to work around
this problem temporarily.

Thanks for the patch and for the hint. I used that and after some more or less horrible hacks I've got to compiling platform specific IA32abi plugin which is a mark that time for ppc64le specific build infrastructure is here. :-) My hacks so far including your advice is:

Yes. this is because of a plugin that is x86-specific
Please remove the line IA32ABI \
from build.linux64x64/squeak.stack.spur/plugins.int and start again with ./mvm

Note that SqueakFFIPrims \ in plugins.ext might also be a candidateā€¦

Thanks, both of those removals were needed. Now I do have compiled VM in the tree. I've downloaded squeak image (5.3 latest), unzipped it, set SQUEAK_IMAGE to point to file and was able to start squeak. The UI complains about missing source file, but otherwise run -- as far as me as ST newbie can see... Thanks!

I've attempted to also start pharo8.0 image, but this complains (although run) with "Callout mechanism not available". It's probably a result of "GetPwdViaFFI" call as far as I can see and if this is FFI, then indeed, it may complain...

That said, This is really cool! Can you post a screenshot of the about-squeak dialog on squeak-dev or vm-dev?
