[ECOS] Troubles building gcc for sh-elf

[Stephen Williams <steve at icarus dot com>]

This is not working for me. I am able to build binutils-2.10.1 --target=sh-elf
no problem on my Linux/alpha machine, but when I try to compile the
gcc-20001113 snapshot,  get the error shown below. I believe it's getting
the right assembler, and when I try for example binutils-2.9 it fails
even earlier.

However, I don't see a problem with binutils. I generated the .s file
with that command and looked on line 86. It is here...

	.type	_fini_dummy,@function
_fini_dummy:
	mov.l	r14,@-r15
	mov	r15,r14
		.section	.fini
	mov.l	1f,r1
	mova	2f,r0
	braf	r1
	lds	r0,pr
0:	.p2align 2
1:	.long	___do_global_dtors_aux - 0b  # <--- line 86
2:

It seems to be failing on the expression ``___do_global_dtors_aux - 0b''.

Sure enough, 0b is on the previous line (and this code is in the .fini section)
but the __do_global_dtors_aux is way back around line 20, and in the .text
section. I can't be the only one who is trying to get eCos to happen on
an sh processor, it's listed as a supported product, for Pete's sake!
It's acting as if the target type is not supported and I should be using
something other the --target=sh-elf.

So what should I be doing differently, that will be compatible with
eCos?
