Hi all,
I've hit a probable assembler bug trying to build a Thumb-2 kernel:
Trying to assemble the attached file, I get:
arch/arm/kernel/relocate_kernel.S: Assembler messages: arch/arm/kernel/relocate_kernel.S:10: Error: invalid offset, value too big (0xFFFFFFFFFFFFFFFC) arch/arm/kernel/relocate_kernel.S:11: Error: invalid offset, value too big (0xFFFFFFFFFFFFFFFC) arch/arm/kernel/relocate_kernel.S:58: Error: invalid offset, value too big (0xFFFFFFFFFFFFFFFC) arch/arm/kernel/relocate_kernel.S:59: Error: invalid offset, value too big (0xFFFFFFFFFFFFFFFC)
The code appears correct and resonable, except that there should be a .align directive before the data words at the end of the file (but adding this doesn't fix the error)
Assembling in ARM (i.e., without -mthumb), or deleting the .globl lines associated with the affected target symbols, the problem goes away.
I believe this may be already by tracked by CodeSourcery as is issue #8775 (?)
Has anyone hit this issue before? Is it fixed upstream?
Any help much appreciated.
Cheers ---Dave

Yes, as you say it is CS Issue #8775, reported by ARM. The bug should be fixed in the imminent CS SG++ release. I do not think the patch is upstream yet.

Hi, thanks for the reply,
Yes, as you say it is CS Issue #8775, reported by ARM. The bug should be fixed in the imminent CS SG++ release. I do not think the patch is upstream yet.
Can we get it upstream and/or into the linaro tools?
For development purposes I may be able to bodge around it or use different binutils, but we'd want this to be fixed in the default binutils if we're to build Thumb-2 kernels for natty.

There's no such thing as Linaro Binutils, just yet.
I'll ask the right person to push it upstream. However, this may not happen right away.

Ummm, yes... I keep making that mistake. For "linaro", read "ubuntu".

Thanks
Can you suggest the rough timescale? If the patch can get pushed within the next few weeks that would be good.
Cheers ---Dave
Hi Andrew. Any news on the upstreaming? I'm happy for the Toolchain WG to do the work as it helps Linaro as a whole, so if there's a patch available then I'll ask Richard S or Chung-Lin to get it upstream.
Dave, has this been reported upstream?

I believe not, but I could be wrong.
