--disable-symbols is specified and to ensure that production
mode (where symbol stripping is usually a part of the FLAGS)
doesn't conflict with --enable-symbols. This will allow better
(though still limited) debugging of production/optimized code.
The PGI, XLC, Intel, and Solaris files were not modified and
do not generate the symbol removal flag at this time. They'll
be updated in future check-ins. In the meantime, production
mode on those platforms still usually strips symbols.
This check-in also updates the Cygwin-specific files to use
the new autotools FLAGS and option scheme when uncommon
(non-gnu, etc.) Fortran compilers are used.
Tested on: 64-bit Ubuntu 15.10 (Linux 4.2.0 x86_64) gcc 5.2.1
autotools serial (prod/debug w/ and w/o symbols)
symbol presence/absence checked with objdump
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
Added -qflag=w:w to config/ibm-flags. This will suppress informational
messages on AIX, suppressing thousands of "__attribute__ is non-portable"
messages in the AIX nightly test output.
Tested on: Nothing. I have no access to an AIX machine.
Added code to display the version information of XL fortran and C++ compiler
version information. (This is just a quick fix for the AIX XL compilers.
The overall algorithm of compilers version information needs an overhaul.)
Tested: ADA machine. (No committest because the changes applied to AIX XL
compilers only.)
RUNSERIAL=${RUNSERIAL="env LDR_CNTRL=MAXDATA=0x20000000@DSA"}
kind of mess things up for the parallel HDF5 configure.
Changed it to
RUNSERIAL=${RUNSERIAL="env LDR_CNTRL=MAXDATA=0x20000000@DSA MP_PROCS=1 MP_TASKS_PER_NODE=1 poe"}
if --enable-parallel.
Also merge powerpc-ibm-aix5.x with ibm-aix by making powerpc-ibm-aix5.x to
source ibm-aix just like ibm-aix6.x. This is in preparation that all AIX
platforms will eventually just use ibm-aix directly.
Fixed a small problme in ibm-flags: some older xlc (e.g. v7.1) prints the
version information with a leading blank. So, accommodate this pattern by
removing the "^".
Tested: LLNL uP, 32/64bits, serial/parallel. (parallel has tests failed
but this change is mainily for configure issues.)
Also tested BP, 32/64bits but serial only.
Added ibm-flags to display the IBM XL compilers version information so that configure
can report them in the configure summary and the libhdf5.settings file.
For now, only the C compiler (xlc) versions are displayed.
Also moved the C compiler options setting from ibm-aix to ibm-flags.
Tested: NCSA Blue-print, both 32 and 64 bit modes.
