[Caml-list] aix51 native-code assembly problem

[Ward Wheeler]

Hello,
	A colleague is trying to compile an application (mostly OCAML, a little C) 
for the aix51 operating system and get's the following error when making 
native (bytecode compiles fine).  Has anyone seen this?  Anyone know of a fix?
Thanks,
Ward Wheeler

(make poy

/tmp/biosci/camlasm2b4f35.s:159321: Error: relocation overflow
/tmp/biosci/camlasm2b4f35.s:159325: Error: relocation overflow
Assembler error, input left in file /tmp/biosci/camlasm2b4f35.s
make: The error code from the last command is 2.

It's been forever since I've played on the Power Architecture.  But IIRC, 
the Power/PowerPC architecture conditional branchs have a maximum range of 
like 64K (IIRC).  For conditional branchs longer than that, you need to 
branch over an unconditional branch (which jumps a lot farther).  This 
looks to be what you are hitting.

This is a known issue with the PowerPC code generator of ocamlopt,
however it should normally be fixed in OCaml version 3.06.
If you're not using 3.06, I suggest an upgrade.  If you are already
using 3.06, I'd be interested in obtaining the sources in order to
reproduce the problem.  (Please send them to me directly.)
