Hi maintainer of lang/go and ports ML, Latest go gives an Illegal Instruction on arm64. I'm running FreeBSD-14/arm64 on RPI4. Compilation of lang/go goes well. But follow-up ports like grafana7 and mongodb42-tools coredump during compilation. [00:01:12] ===> Building mongodump from ./mongodump/main [00:01:12] go tool compile: signal: illegal instruction (core dumped) [00:01:12] *** Error code 1 [00:01:12] [00:01:12] Stop. [00:01:12] make: stopped in /usr/ports/databases/mongodb42-tools I tried to get some debug info. I don't know if I got useful information here. I don't use gdb/lldb and go that often. root@rpi4:/ # /usr/bin/lldb -c var/tmp/65534.compile.0.63376.core /usr/local/go/pkg/tool/freebsd_arm64/compile (lldb) target create "/usr/local/go/pkg/tool/freebsd_arm64/compile" --core "var/tmp/65534.compile.0.63376.core" Core file '/var/tmp/65534.compile.0.63376.core' (aarch64) was loaded. Cannot read termcap database; using dumb terminal settings. (lldb) bt This version of LLDB has no plugin for the go language. Inspection of frame variables will be limited. * thread #1, name = 'compile', stop reason = signal SIGILL * frame #0: 0x0000000000074880 compile`_rt0_arm64_freebsd at rt0_freebsd_arm64.s:9 frame #1: 0x0000000000074880 compile`runtime.asyncPreempt at preempt_arm64.s:148 (lldb) quit NB: This compiles fine on the FreeBSD pkg builders. So it might have something todo with ARMv8.1 vs ARMv8.2 instruction set. I'm not familiar with this. NB2: It also compiles fine in a FreeBSD-12 jail which uses an older clang version. Regards, Ronald.
