[parisc-linux] Postgresql Math errors on a 710 & 735

[Jim Buttafuoco]

All,

I am trying to Postgresql working on my 710 and 735 hp systems and I am having problems with some math functions and 
the postgresql fokes sent me over here.  Does anyone know of any problems with math on these systems.  In the next few 
days, I will put together a small C program as an example of the problem

One example of an issue is just "select 'infinity'::float8;" 

If this is NOT the correct list please let me know also.

Thanks for your time.
Jim

No issues are known.  PA 1.1 lacks the fneg instruction.  Thus, you
may have issues with -0.0 if you use unsafe_math_optimizations.  It
also lacks some convert insns that are provided in hardware in PA 2.0.
The kernel emulates some of the insns that are missing.  I think you
need to provide a C example showing the problem(s).
