Hi Kevin,
Thank you very much for the quick reply.
The tests/GMP libs seem to be working (pretty) fine now :-).
Changes to "invert_limb.asm" were the key changes.

Yep, Sure.
i) I've been trying to install ans work with GMP on HPUX (ansi C
Compiler) and Linux
It's surprising that you can install using only the kernel. Perhaps
you mean the GNU/Linux system.
I tried two different configurations on an ia64 machine.
Linux/gcc or GNU ( no problems, works perfect)
HPUX/ansic C compiler (works fine now)
Though
installation and tests (including "make check") work fine with
gcc/Linux, t-constants fails during the first phase ("make check"),
with an error (5 out of 4 tests passed),
PP_INVERTED == 21cfe6cfc938b36b, but pp_inverted_calc == 0
I think we had at least two problems in 4.1.2 with hpux ia64, firstly
that we only know lp64 mode in the asm code, but didn't force
CFLAGS=+DD64 in the build, and secondly that the data in that
invert_limb.asm was for little endian, whereas hpux runs in big endian
mode. You might like to try forcing the CFLAGS if you haven't
already, and change the data to
.LC0: data4 0x403f8000, 0x00000000, 0x00000000, 0x00000000 C 2^64
data4 0x407f8000, 0x00000000, 0x00000000, 0x00000000 C 2^128
This will all be addressed properly in the next release. Until then
unfortunately we can't really claim to work on hpux ia64, or only with
the generic C code (ie. cpu "none", which will be very slow).
Please do let me know if you are aware of any other HPUX/ia64 issues
with GMP. The current version I have compiled on HPUX seems to be a
little slow. Would there be any GMP fine tuning probabilities to get it
working faster on an ia64 (any fine tuning tips) ? I have the maximum
optimization set (O3) on HPUX.
The compilation works just fine on Linux with Gcc. However with
aCC/HPUX, the conversion of assembly file from invert_limb.asm to
tmp-invert_limb.s and then to invert_limb.o does not work (bcoz of
.section .rodata ).
Thanks, yep, that should be just ".rodata".
first, mp_size= 1, mp_d=1
sec, mp_size=1, mp_d=0
Hmm. Something has gone wrong before this point, a value 0 should be
represented with size==0.
These problems seem to have been rectified with the changes to
invert_limb.asm. So thanks again :-).
Best Regards,
Prashanth
