I have modified elf32_sparc.sh to add this line:
That is showing up as the =XXX fill pattern in the
ld scripts. But it does not seem ld in binutils 2.20.1
is honoring it. This is the disassembly from objdump.
Even the address for the call is bogus.

Any ideas on what to look for that might be going wrong?
