I tried bulding gdb 12.1 on macOS 12.4 with an Apple M1 chip, but it öooks like that target is not supported.

Can I ask if there are plans to support that platform, or even work in progress that I could try out?  (I'd use it for debugging Emacs on macOS.)

TIA

Arm has macOS-hosted arm-none-eabi tools, but I don't think native aarch64 debugging on macOS is supported, as you said.

I can't speak for other contributors, but I don't know of any plan to support that OS/arch combination for GDB. We're open to
accepting patches though.

I think LLDB is the way to go on macOS.

Unfortunately that seems to be the only option right now, but it's a nasty one.  The UI is obnoxious, and it can't debug GCC output at all unless it was compiled with -O0.

Technically we have darwin native support for x86-64 (don't know how well it works). If that works well, It might be a matter of implementing the native parts for aarch64.

The x86-64 Darwin GDB has been useable for me in the past, so yes, an aarch64 port of that would be a promising notion and should do a much better job debugging optimized code.
