System: NetBSD cuba.soc.lip6.fr 5.99.55 NetBSD 5.99.55 (LOONGSON) #52: Mon Aug 29 21:38:41 CEST 2011 bouyer@roll:/dsk/l1/misc/bouyer/tmp/evbmips64el/obj/dsk/l1/misc/bouyer/current/src/sys/arch/evbmips/compile/LOONGSON evbmips
Architecture: mipsel
Machine: evbmips-mips64el
>Description:
	On mips64el platforms, the default userland format is N32, but
	gdb is configured for mips64el and doesn't understand N32:
cuba:/home/bouyer/src/usr.bin/ftp>file ftp
ftp: ELF 32-bit LSB executable, MIPS, N32 MIPS-III version 1 (SYSV), dynamically linked (uses shared libs), for NetBSD 5.99.55, with unknown capability 0xf41 = 0x756e6700, with unknown capability 0x70100 = 0x3040000, not stripped
cuba:/home/bouyer/src/usr.bin/ftp>gdb ftp

This GDB was configured as "mips64el--netbsd"..."/home/bouyer/src/usr.bin/ftp/ftp": not in executable format: File format not recognized

>How-To-Repeat:
	try to run a userland binary under gdb on a mip64el platform.
>Fix:
	Ideally, gdb should understand both N32 and N64, and optionally O32,
	as libraries are installed for all 3 formats.

State-Changed-Why:
I've run and debugged o32 and n32 binaries on mips64el succesfully.
n64 has trouble setting breakpoint (cannot access memory), but that is a separate issue.
