[Vm-dev] Building VMMaker image supporting AMD64 and AArch64 ISAs on Linux

Hi Eliot and others,

I'm trying to build working VMMaker image in order to see what  machine code Cog generates for some simple methods - without  success so far. All this is on Linux on AMD64. Detailed report on what exactly I did and what errors I got is below.

In short: (i) does AArch64 sim plugin works on modern linuxes, does anyone use it there? (ii) if so, what's the correct incantation to compile it. (iii) using code in workspace labelled "In-Image Compilation Workspace", is it supposed to work for every method and every ISA or is it normal that it fails with DNU for some methods? I managed to compile but the  trivial ones.

Thanks! Jan

================================================== ==== Below details what I did and errors I got ===

I'm using this commit:

commit 330d6779ad2ecbce1f07131f53d75cd168165f0b (HEAD -> Cog, origin/HEAD, origin/Cog) Author: Christoph Thiede christoph.thiede@student.hpi.de Date: Thu Aug 17 13:32:52 2023 +0200

Here's what I did:

* IIUC, first I need to build bochs and BOCHS 64 simulator, so

cd opensmalltalk-vm/building/linux64x64/bochsx64 ./conf.COG ./makeem

That built just fine.

* Then I built gdbarm64 simulator:

cd opensmalltalk-vm/building/linux64x64/gdbarm64$ ./conf.COG ./makeem

Again, no problem so far.

* Then I tried to build the VM:

cd opensmalltalk-vm/building/linux64x64/squeak.cog.spur/build ./mvm

That failed soon:

.../opensmalltalk-vm/platforms/unix/vm/sqUnixMain.c:1832:10: warning: format string is not a string literal (potentially insecure) [-Wformat-security] printf(optionStrings[count]); ^~~~~~~~~~~~~~~~~~~~ .../opensmalltalk-vm/platforms/unix/vm/sqUnixMain.c:1832:10: note: treat the string as an argument to avoid this printf(optionStrings[count]); ^ "%s", .../opensmalltalk-vm/platforms/unix/vm/sqUnixMain.c:2324:38: error: incompatible function pointer types assigning to 'void (*)(int, siginfo_t *, void *)' from 'void (int, siginfo_t *, ucontext_t *)' (aka 'void (int, siginfo_t *, struct ucontext_t *)') [-Wincompatible-function-pointer-types] sigsegv_handler_action.sa_sigaction = sigsegv; ^ ~~~~~~~ .../opensmalltalk-vm/platforms/unix/vm/sqUnixMain.c:2331:38: error: incompatible function pointer types assigning to 'void (*)(int, siginfo_t *, void *)' from 'void (int, siginfo_t *, ucontext_t *)' (aka 'void (int, siginfo_t *, struct ucontext_t *)') [-Wincompatible-function-pointer-types] sigusr1_handler_action.sa_sigaction = sigusr1; ^ ~~~~~~~ 1 warning and 2 errors generated.

This is using clang version 16.0.6 (which mvm script enforces on line 20)

* Then I tried to build the VM again, this time with GCC (version 13.2.0 by editing mvm line 20):

cd opensmalltalk-vm/building/linux64x64/squeak.cog.spur/build ./mvm

This failed to compile too, though with different error:

* Then I gave up on AArch64 support and tried only with AMD64 by cleaning opensmalltalk-vm/building/linux64x64/gdbarm64. This time VM compiled fine.

* As a next step, I built VMMaker image:

cd opensmalltalk-vm/image ./buildspurtrunkvmmaker64image.sh -vm ../building/linux64x64/squeak.cog.spur/build/squeak.sh

This worked just fine, producing Spur64VMMaker.image

* Finally, I tried to see AMD64 (since I could not build AArch64 sim plugin) machine code  for some method, so I executed following smalltalk code in a workspace (which is just a modification of what is suggested in one of pre-opened workspaces I only changed memory manager class and ISA):

StackToRegisterMappingCogit genAndDis: SequenceableCollection>>#indexOf:startingAt:ifAbsent: options: #(ObjectMemory Spur64BitCoMemoryManager ISA X64).

This resulted in DNU:
