Hi,

While trying to build the latest (At revision 72733.) svn trunk on AuroraUX (A
OpenSolaris derived distribution; Same result on SXCE snv_110), We hit a
strange position-independent code, relocatable references problem that has been
exceedingly hard to debug so far.

"ld: fatal: relocations remain against allocatable but non-writable sections"

Details of the failed build here:
http://pkg.auroraux.org/llvm_fail.txt

Configure Info:
./configure --prefix=/export/home2/edward/lab/TEST_BUILDS/llvm/test1
--enable-optimized --enable-assertions --enable-expensive-checks

Moving /usr/bin/ld aside 'fixes' the problem. Looking at a diff of the
config.log by moving /usr/bin/ld aside --export-dynamic gets set to 'yes' and
comes into effect, not sure of how much relevance's, although a very
interesting observation.

Tinkering around we figured that something may not have been getting built with
-fPIC somewhere somehow..
So we past --enable-pic=no at the end of the configure line seems to work
around this issue!

Details of the pass build (--enable-pic=no) here:
http://pkg.auroraux.org/llvm_pass_disable-pic.txt

The only other *idea* I could come up with is that there is hand-written
assembler code that has not been coded with the appropriate
position-independent prototypes.

I been trying very hard to try to fix this myself, however, am at a bit of a
loss, any pointers would be greatly appreciated.

Thanks for your time,
