Well, the obvious questions is "Does hpux11 have a sqrtl() in libm?"

Possibly, relates to PR 51057

No.  It only has basic quad arithmetic.  Previously, the libquadmath  
version was
used.

I filed a separate bug because I thought it was a different issue.

I said 'related' not 'duplicate'.  In both cases, sqrtl() is
not found.

Possibly, you referred to the wrong PR.  PR 51057 is about the precision
of IBM long double.

Read the entire PR.  You'll eventually find the thread
starting at

http://gcc.gnu.org/ml/fortran/2011-11/msg00051.html

hpux11 appears to be yet another OS that has sufficient quad
support that gfortran detects a REAL(16) type, but the OS
lacks the basic libm functions.

Except possibly for hpux11.31, the OS only provides support for
basic arithmetic operations.  These are soft implementations.
GCC has supported these operations for many years.  This is why
gfortran detects a REAL(16) type. The support is sufficient to
build libquadmath.  As far as I know, it works correctly (no
errors in testsuite).

There was some discussion last year about adding support
to provide `l' aliases to the `q' routines in libquadmath.

Please confirm that it no longer fails.

There is now a dg-effective-target check which does not run the test case if
for the highest available floating-point data type (here: REAL(16)) no sqrt
function is available.

Thus, the test case will no longer fail as it is not run.

I think one could add - for HPUX - a configure test whether (a) libquadmath can
be build, (b) whether "long double" and __float128 are the same, and (c)
whether "sqrtl" is not available. If this is fulfilled, one could provide the
symbols in libquadmath. But that's a different issue and should be started by
someone who has access to such a system.

http://gcc.gnu.org/ml/gcc-testresults/2012-01/msg01427.html shows that
4.7.0 20120113 (experimental) [trunk revision 183162] (GCC) testsuite
on hppa64-hp-hpux11.11  has no gfortran failures.

While that's not on hppa2.0 as in the the original report (comment 0), also
happa64 showed the failure, cf.
http://gcc.gnu.org/ml/gcc-testresults/2012-01/msg01078.html

Thus: Closed as fixed. Feel free to reopen if it shows up on hppa2.0.

Thanks again for the report.
