Re: gcc12 incompatible with ctfconvert?

[Rin Okuyama <rokuyama.rk%gmail.com@localhost>]

Hi,

Our in-tree GCC is currently forced to DWARF 4 by default:

http://cvsweb.netbsd.org/bsdweb.cgi/src/external/gpl3/gcc/dist/gcc/common.opt.diff?r1=1.13&r2=1.14&f=h

Note that ctfconvert(1) in FreeBSD-current does not support DWARF 5 also:

https://cgit.freebsd.org/src/tree/cddl/contrib/opensolaris/tools/ctf/cvt/dwarf.c#n1973

Thanks,
rin
