[OpenSmalltalk/opensmalltalk-vm] Difficulties to compile Bochs plugins (#427)

So we won't get support for compilation on uptodate machines... We cannot upgrade easily, since there are COG specific changes requiring to be replayed... `grep -r COG processors\IA32`. I also have doubts about the `conf.COG` files: is `--disable-x86-64` really what we want? https://github.com/OpenSmalltalk/opensmalltalk-vm/blob/e77147b63208fb40a9a1… https://github.com/OpenSmalltalk/opensmalltalk-vm/blob/Cog/processors/IA32/… -- You are receiving this because you are subscribed to this thread.

[OpenSmalltalk/opensmalltalk-vm] Support for musl (instead of GNU libc) when building the VM for embedded system (#304)
by Xuan Sang LE 14 Feb '20

14 Feb '20

Hello, I have a small issue when building (cross-compile) the Smalltalk VM on an ARM(v6) embedded linux system (Nano Pi neno and Raspberry Pi Zero) that uses Musl as default libc implementation. The problem is that the code and the configure script does not have official support for Musl, so I created a patch file that adds support to Musl, you can find the [patch here](https://github.com/lxsang/antix/blob/master/sm_vm_musl.patch). With this patch, i am able to cross-compile on the ARM toolchain for my system; with 4 plugins: ``` FilePlugin \ SqueakSSL \ SqueakFFIPrims \ SocketPlugin ``` You can find the build [script here](https://github.com/lxsang/antix/blob/master/packages/smalltalk-nano-p… For now, i can live with this dirty trick, but i would be verry happy if the mainline VM has official support to Musl. That's why i create this issue. Thanks -- You are receiving this because you are subscribed to this thread.

[OpenSmalltalk/opensmalltalk-vm] passing struct by value does not respect x86_64 SysV ABI (#443)
by Nicolas Cellier 01 Feb '20

01 Feb '20

The case when a structure passed by value is passed via memory (thru a pointer), via registers, or just stack, same for structure return value is much more complex than what is programmed currently in both FFI and Alien (FFI and Alien currently do not even agree...). This badly need more test cases and more attention. See squeak-dev thread **[squeak-dev] Alien primFFICall returning struct with 64bit vm** http://lists.squeakfoundation.org/pipermail/squeak-dev/2019-November/204974… See draft for ABI, near page 21 and 24 (not very clear) https://github.com/hjl-tools/x86-psABI/wiki/x86-64-psABI-1.0.pdf -- You are receiving this because you are subscribed to this thread.

Build Update for OpenSmalltalk/opensmalltalk-vm ------------------------------------- Build: #1935 Status: Errored Duration: 1 hr, 59 mins, and 54 secs Commit: 84ccd0a (Cog) Author: Eliot Miranda Message: Change any and all sqMakeMemory...Executable... prototypes and implementations to use usqInt for address arguments (sqInt must be used for teh delta arg). IMO we should use usqInt where it makes sense (our APIs rather than OS APIs). I'm not interested in supporting 64-bit oops in 32-bit hosts, or 32-bit oops in 64-bit hosts, so I think it safe to assume that usqInt is equiavlent to usqIntptr_t, & sqInt to sqIntptr_t, and they're shorter. I'm open to persuasion so if I'm wrong please correct me (and the source).
