[Debootloaders-silo] Bug#721396: Trying to build silo in 64 bit userland (aka sparc64)

[Axel Beckert]

Hi David,

I took over maintenance of silo in Debian from Jurij, and I'm
currently trying to built silo on the architecture "sparc64", i.e. not
only with 64-bit kernels but also 64-bit userland. See also
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=721396 and
https://wiki.debian.org/Sparc64

But compilation fails at some assembler code:

$ gcc -m64 -Os -Wall -I. -I../include -fomit-frame-pointer -fno-strict-aliasing -DSMALL_RELOC=0x280000 -DLARGE_RELOC=0x380000 -fno-stack-protector -c divdi3.S

$ gcc --version
gcc (Debian 4.8.1-9) 4.8.1

This doesn't happen if I compile it with -m32 instead of -m64 in 32
bit userland.

A little bit of searching the web brought me to this thread from 2003:
http://marc.info/?l=linux-sparc&m=106519022917651&w=2

Same error message, same project, same file name, just 10 years
earlier. That gives some hope that you may have an idea what's going
on there or what may be wrong.
