Did you know when this started regressing ?
I suspect this one is also not Ada related, so it would be good to identify
when this started failing.

There's potentially two separate issues involved in this PR
and 13528:
1) The float to integer conversion of an Inf which causes a
SIGFPU and the termination of the acats test sequence.
This is definitely a testsuite/ada problem. I don't have
a copy of the IEEE spec handy but the PA-RISC 2.0 Architecture
book indicates that an unimplemented exception is always
signaled for this condition.
2) The failure of various cxg* tests (and some others) due
to the error limit for the test being exceeded by a small
amount.
I suspect that the cxg* failures have been present on the hppa2.0w-hp-hpux11
port since the acats testsuite was installed. This report represented
the first successful build of ada since the testsuite was installed. I
could do a build just after the testsuite was installed to see if there
was any regression from that time. I would have to backport Roger Sayle's
loop.c patch. It resolved the miscompilation of gnat1 which prevented
builds for a long time.
The numeric failures don't occur on the hppa-linux port. Thus, I doubt
the problem is directly in the GCC code. The primary differences between
the two ports are:
a) HP libc/libm versus glibc
b) Long double on hppa-linux port is the same as double. Long double
on hppa-hpux port uses HP "quadlib" routines in libc.
c) Linux port has flat memory model and doesn't need to be built with
-mdisable-indexing.
`c' usually results in segmentation faults, so I doubt it is the problem.

The cxg are not failing for a small amount given the log you gave,
and it looks like it concerns Long_Long_Float handling.
I suspect it might be general weakness in handling Long_Long_Float
on platforms where it's not the same as Long_Float, see ada/14988

With gcc 3.4.2 (release) on hppa2.0w-hp-hpux11.11, the nature of the failure
has changed. The ada testuite now hangs when cxg2014 is run.
...
BUILD cxg2014.adb
gnatmake --GCC="/xxx/gnu/gcc-3.3/objdir/gcc/xgcc -B/xxx/gnu/gcc-3.3/objdir/gcc/"
-gnatws -I/xxx/gnu/gcc-3.3/objdir/gcc/testsuite/ada/acats/support cxg2014.adb -

gnatlink cxg2014.ali --GCC=/xxx/gnu/gcc-3.3/objdir/gcc/xgcc -B/xxx/gnu/gcc-3.3/o
bjdir/gcc/
RUN cxg2014
The hang occurs at exactly the same point as before. Someday I'll try
and debug this further.
