Subject: RE: Recent Glibc breaks CPQ-Java?

It appears that and a similar fix for the ctype errors with the compaq
extended math library has resolved this issue.

Thanks again.


I've found the following CFLAGS very useful on my Alpha:

CFLAGS=-O3 -mcpu=ev56 -mtune=ev56 -mieee -mno-soft-float -mfp-regs -pipe

(the -mno-soft-float -mfp-regs attempt to use the internal FP components of
the Alpha processor and the -mieee corrects for NAN (not-a-number, e.g.
divide by zero) issues).  

Anyone have other/better optimizations for ev56 class?

I appreciate the feedback.  I haven't had the time myself to research and 
thought I'd ask if anyone else had seen it.  Before delving further into it 
and filing a bug report.  (I like to try and figure out the solution or at 
least part way down the path before filing a bug).

I knew the runtime was the old compaq java and have been trying to locate a 
source to a more recent release.  Just some of the stuff I've installed on 
my alpha now doesn't work as the jvm fails.

I'll try the patch when I get another shot at it and report back soonest.
