Build failure: Error: attempt to move .org backwards

Build failure: Error: attempt to move .org backwards

[Andreas Born]

Hello,

having trouble building the latest bzr 3757. This happens with gcc 4.5.2 
on Salix/Slackware 13.37 x86_64 system, but doesn't happen with gcc 
4.6.2 on Arch Linux x86_64.
I also checked recent other reports of such problems, but wasn't able to 
find a solution.

Here's some output:

Hi,

   Yes, I'm seeing that also.  I guess version 4.5.2 of the compiler just isn't 
as efficient as the most-recent GCC.  I edited include/grub/offsets.h:

And changed:
#define GRUB_KERNEL_I386_PC_NO_REED_SOLOMON_PART 0x7e0

To:
#define GRUB_KERNEL_I386_PC_NO_REED_SOLOMON_PART 0x7f0

  And that was enough.  phcoder posted to this list not-too-long-ago with that 
suggestion for another person as well.  He said you can increase it as long as 
you don't do it too much and as long as the value is divisible by 8.

[Andreas Born]

Yes, that's exactly what I tried, but apparently it doesn't work. The 
lowest working value is 0x800 here.
So gcc 4.5 seems to be worse than 4.4 and 4.6 better than both.

Re: Build failure: Error: attempt to move .org backwards

[Seth Goldberg]

Hi,

  I should also mention that I ifdef'ed out the reed-solomon add redundancy 
stuff in grub-setup (since it was causing me problems I haven't had time to 
identify).  You may want to try that also -- make sure you ifdef out the code 
that sets the redundancy size also, otherwise, you're going to crash.

Re: Build failure: Error: attempt to move .org backwards

[Andreas Born]

Yes, I'm going to try that. Just test booted an iso image with qemu and 
with 0x800 and that fails printing garbage to the screen. So probably 
that's too big.
