[9fans] rb kernel vs acid

[9fans] rb kernel vs acid

[erik quanstrom]

if i type src(main) when debugging a routerboard
kernel, i get rather puzzling output

	; acid 9rb
	9rb:mips ELF32 executable
	/sys/lib/acid/port
	/sys/lib/acid/mips
	acid; src(main)
	no source for ?file?	# fileline (see symbol(2))

this is especially odd since ktrace does work, acid
does appear to disassemble correctly, map() appears
to be reasonable and e.g., /bin/cat works as expected.

does anyone else see this, too?

by the way there is a patch for the type skew
in symbol(2): /n/sources/patch/mach-man-type

Yes, I have the same issue here.

i've found part of the problem is machbytype doesn't get the joke
with the type is 0x7f E L F.  supposing machbytype did the right thing
when faced with an elf header (with richer arguments), it's an open
question for me if libmach could then figure it out.
