Even better than my previous toot, you can get the names of the running processes for a given architecture with:

osascript -e 'tell application "System Events" to return name of processes whose architecture is "x86_64”’

You can change “x86_64” to ”arm64” for native Apple Silicon processes.

And if you prefer to get process IDs, you can change name of processes to unix id of processes.

#AppleScript #Rosetta #Arm64 #x86_64 #macOS #CLI

Back to work on packaging @hare for @fedora, let's see how much I can bang out in a few hours. The resulting artifacts are going to be fairly simple, but not particularly packager friendly. That's a day-2 project.

@hare @fedora @centos Hot off the press, any volunteers willing to test out the latest toolchain build from my COPR? It provides and builds for , , and .

$ dnf copr enable mroche/hare
$ dnf install hare

Some other changes:

  • New cross-compile meta packages for and dependencies.
  • I've created a convenience script, harex, to switch to non-GNU toolsets. Just set HARE_XCOMPILE_TOOLCHAIN to "llvm". User specified env vars will still be respected.

Spent part of my at looking at bootstrapping 0.9.26 from on architecture. And thanks to mantainer @janneke for his help with debugging various issues. We can now build initial binary and it can even run some simple commands such as --help or -vv.

Unfortunately, we still hit some critical bugs when trying to use this tcc binary to rebuild itself but hopefully we are not far now.

VMS Software (VSI) has a Python qualification tool available for determining hardware compatibility of OpenVMS x86-64 on your local Intel or AMD server:
https://vmssoftware.com/openkits/alpopensource/vmscheck.zip

Example run:

OpenVMS 9.x compatibility quick-check

Summary:
Your CPU appears to be compatible with OpenVMS 9.2 and up.

Detailed info:

Vendor ID : GenuineIntel
CPU name : Intel(R) Core(TM) i5-7500 CPU @ 3.40GHz

Necessary for OpenVMS 9.x:
Intel or AMD CPU : Yes
SSE 4.1 : Yes
XSAVE : Yes
TSC : Yes
APIC : Yes
MTRR : Yes

Optional for OpenVMS 9.x:
PCID : Yes
X2APIC : Yes
FSGSBASE : Yes
MD_CLEAR : Yes
XSAVEOPT : Yes

And to think, Alpha EV7z peaked at 1.3 GHz, and a top-binned Itanium Poulson, err, Kittson peaked at 2.66 GHz, and here an old and slow i5 is now well past both at 3.4 GHz. (Yes, I am well aware of the perils of comparing clock speeds across disparate architectures, but thanks for mentioning that.)
