  This is what is meant to happen if you pass the -r flag to the linker.
Are you *absolutely* sure you aren't using the -r flag?

There's no such thing as `as-2.95.2'.  2.95.2 is the number of the
latest release of GCC, but GCC and the GNU assembler are separate
projects.  If you want to report a bug in the GNU assembler, get
binutils 2.10.1 and, if it fails, post a bug report to
binutils@sources.redhat.com

AS-BUG????????

[Sobhy Gad]

hi again,

as I allredy said I as-2.95.2 has a BUG.
absolut  jumps does not work. only with the verion as-2.9.1 it works
very good.

	.long	label_y
	jmp	label_x
	:
label_x:
	:
label_y:

when I compile it with 2.9.1 it works good. any other verion does NOT
work.
this is the result of as-2.95.2 for jmp label_x is:
41F9 0000 0000. 
as you see >> 0000 0000 << should be a distence to the label
it does not calculate the jump.
the same with     .long label_y    is tranlated as 0000 0000
insted of the addresse of label_y.
but when you load the label to an addresse register let us say a0 and
then

jump	(a0)

it works.

STRANGE, is'nt it ?????????
I think there is a bug with the absolute JUMPS.

best regards
S. Gad

I had the same matter but I don't know where is the matter, it appends when
the label doesn't exist in the C source code, but the linker don't give me
an error it put label at adress 0... I think it can try to identify it like
a dynamic loaded object... But a don't know more... If you have a idea and
more, a solution... I'm really interresting :-)

CU,
Paul

Hmmm, normally this (interpreting the labels to real adresses) is done
by the linker. Have you passed your object file to the linker?

Regards,

AS-BUG????????

[Sobhy Gad]

I try to compile an asm-file with as-2.9.5.2 for m68k (cpu32 built for
win32) but it.
does not really work:

	jmp	label_x
	:
	:
label_x:
	:
	:
I get in the bin file that the list fiel:
41F9 0000 0000. insted fo 0000 0000 should be a distence to the label
it does not calculate the jump.
also .long label_y is tranlated as 0000 0000
################################################
when i compile it with the version 2.9.1 IT WORKS very well.
#################################################

STRANGE...could any one help

best regards
S. Gad
