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 -
largs --GCC="/xxx/gnu/gcc-3.3/objdir/gcc/xgcc -B/xxx/gnu/gcc-3.3/objdir/gcc/"
/xxx/gnu/gcc-3.3/objdir/gcc/xgcc -c -B/xxx/gnu/gcc-3.3/objdir/gcc/ -gnatws -I/xx
x/gnu/gcc-3.3/objdir/gcc/testsuite/ada/acats/support cxg2014.adb
gnatbind -aO./ -I/xxx/gnu/gcc-3.3/objdir/gcc/testsuite/ada/acats/support -I- -x
cxg2014.ali
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.

No, I'm afraid not.  The situation is actually worse than before.
In both those test runs, I had to kill the acats testsuite because
it hangs.  The normal timeout doesn't occur.  Thus, we didn't get
to the cxg tests.
