Looking at the sim_tcbinfo.c, it seems that there are only g_reg_offs defined for CONFIG_HOST_X86, CONFIG_HOST_X86_64, and CONFIG_SIM_M32, but sounds that there's no g_reg_offs defined for CONFIG_HOST_ARM64.

If you want to get better debugging experience (thread awareness) on macOS, you have to provide the register layout expected by gdb/clang:
https://github.com/apache/nuttx/blob/master/libs/libc/machine/sim/arch_setjmp_arm64.S
otherwise, you can justt provide a dummy g_reg_offs or skip g_tcbinfo.

I tried to use a dummy g_reg_offs, but I got different errors

➜  nuttx git:(master) ✗ sudo make
LD:  nuttx
ld: warning: pointer not aligned at address 0x10006C612 ('_g_tcbinfo' + 18 from nuttx.rel)
ld: unaligned pointer(s) for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[1]: *** [nuttx] Error 1
make: *** [nuttx] Error 2

I don't want to use the debugger, I just want to be able to make the simulator on my mac. How can I skip the g_tcbinfo?

@duduita could you verify whether #11207 can fix your issue?

I'm out of office for now, but I can try it next week.
