symbols, asserts, profiling, and optimization.
Also much refactoring, improved help, and --enable-<foo> options will
now emit errors on nonsense (e.g.: --enable-foo="asdfasdf").
The libhdf5.settings.in file was also reformatted.
Tested on: 64-bit Ubuntu 15.10 (Linux 4.2.0 x86_64) gcc 5.2.1
serial and parallel autotools w/ various options
Description:
testhdf5/select runs very slow when in --disable-production mode using
pgcc compiler. This was caused by the -Mchkfpstk compiler switch added
to the DEBUG_FLAGS in config/pgi-flags file.
Solution:
Removed -Mchkfpstk from both pgi-flags and pgi-fflags.
See Bug 2026 for dettails.
Tested: (no h5committest test since they don't use PGI compilers.)
Jam (linux32): using pgcc/pgf90/pgCC using default and --enable-production.
Amani (linux64):
using pgcc/pgf90/pgCC (32 bits mode by "-tp k8-32"), using default and --enable-production.
Bug fix.
Description:
PGI v6.0-5 pgf90 compiler has a bug in Mstandard that caused compiling
of legal logical value to fail.
We also have second thought of imposing -Mstandard and -Mdclchk on users
since these flags are included in h5fc.
Solution:
Removed -Mstandard until we can fix the v6.0-5 compiler error
and moved -Mdclchk to DEBUG_FFLAGS so that it is used during development
mode but not imposed on users for production release.
Platforms tested:
heping: production and development mode using v6.0-4 compiler.
mir: production and development mode using v6.0-4 compiler.
Description:
Add source code copyright notice; comment symbols vary by type of file.
Platforms tested:
No changes that should cause any problems. Nonetheless, the tree will
be checked out fresh and tests run immediately post-commit.
Automake version upgrade
Description:
Upgraded automake version from 1.6.2 to 1.9.5.
Changed bin/reconfigure script to use automake 1.9.5.
Changed configure.in and Makefiles to use new FCFLAGS and FC variables
instead of FFLAGS and F9X.
Automake and configure should now do the lion's share of the work
supporting Fortran 9X; macros in acsite.m4 are now mostly unused (will
be cleaned later).
Altered how configure handles pmake; now root-level Makefile.in is
processed by bin/reconfigure to have a .MAKEFLAGS target, since
automake no longer allows us to define unused variables.
Configure now always checks for C++ compiler even if it is not
used, since automake thinks this is the Right Thing To Do and
will break otherwise.
Platforms tested:
Sol, copper, heping, mir, sleipnir, eirene, pommier, kelgia, modi4.
mpich 1.2.6 does not like the tweaking of using -O2 flag.
Comment out the Tweaking since it caused problems to mpich1.2.6.
Need to investigate the reasons and effects to tweak.
Platforms tested:
Tested in heping using mpich 1.2.6 and in eirene uisng mpich 1.2.6.
Bug fix
Description:
When mpicc/mpif90 is a wrapper around a PGI compiler, turn on less
agressive optimization options to avoid testing errors.
Platforms tested:
Linux 2.4 (verbena)
Too minor to require h5committest
Code cleanup/bug fix
Description:
Remove the undocumented "$NOFP" shell variable which would allow production
builds without removing the stack frame. This was cascading between C and
FORTRAN builds and causing problems.
Solution:
Hard-code removing the stack frame for now. Users would have needed to
read the configure scripts anyway, so there's not really much benefit to the
extra knob. Users who need this functionality (production builds with stack
frames) are debugging probably, so they will need to modify the script and
build their own version of the library now.
Platforms tested:
Linux 2.4 (verbena)
Too minor to require h5committest
Bug fix
Description:
Tweak PGI compiler auto-detection to work for version 5.0 compilers as
well as version 5.2 compilers.
Platforms tested:
Linux 2.4 (verbena) w/PGI compilers
Not tested with rest of h5committest platforms
