1) no more f_defs.h file to be included in fortran files
2) all CMPLX explicitly defined as CMPLX(...,KIND=dp)
3) blas/lapack names in lowercase (not all of them, actually)
4) documentation accordingly updated (plus unrelated changes to user_guide)
git-svn-id: http://qeforge.qe-forge.org/svn/q-e/trunk/espresso@5805 c92efa57-630b-4861-b058-cf58834340f0
conversion to real => DBLE
(including real part of a complex number)
conversion to complex => CMPLX
complex conjugate => CONJG
imaginary part => AIMAG
All functions are uppercase.
CMPLX is preprocessed by f_defs.h and performs an explicit cast:
#define CMPLX(a,b) cmplx(a,b,kind=DP)
This implies that 1) f_defs.h must be included whenever a CMPLX is present,
2) CMPLX should stay in a single line, 3) DP must be defined.
All occurrences of real, float, dreal, dfloat, dconjg, dimag, dcmplx
removed - please do not reintroduce any of them.
Tested only with ifc7 and g95 - beware unintended side effects
Maybe not the best solution (explicit casts everywhere would be better)
but it can be easily changed with a script if the need arises.
The following code might be used to test for possible trouble:
program test_intrinsic
implicit none
integer, parameter :: dp = selected_real_kind(14,200)
real (kind=dp) :: a = 0.123456789012345_dp
real (kind=dp) :: b = 0.987654321098765_dp
complex (kind=dp) :: c = ( 0.123456789012345_dp, 0.987654321098765_dp)
print *, ' A = ', a
print *, ' DBLE(A)= ', DBLE(a)
print *, ' C = ', c
print *, 'CONJG(C)= ', CONJG(c)
print *, 'DBLE(c),AIMAG(C) = ', DBLE(c), AIMAG(c)
print *, 'CMPLX(A,B,kind=dp)= ', CMPLX( a, b, kind=dp)
end program test_intrinsic
Note that CMPLX and REAL without a cast yield single precision numbers on
ifc7 and g95 !!!

Note that lqx => lmaxq for consistency with other names
(those ending in x are static dimensioning)

new module uspp_param, shared between PW and CP (in file Modules/uspp.f90)
The flag newpseudo is no longer used to decide whether states with oc=0 are
bound or not: for those states, and only for the old RRKJ format, oc is set
to a negative value, and this signals that they are not bound. Not elegant
but simpler than it used to be. The converter to UPF format did not include
those states anyway. Beware unexpected side effects!

correct place (kinds); module "varie" replaced by "control_flags" (not
yet in pwcom, though) - many many files changed.
64-bit cpus (Opteron, maybe Itanium) should now work if __LINUX64 is defined

- module filnam in pwcom moved to io_files module
- module units in pwcom moved to io_file
From now on, all file names and their unit and attributes (i.e. reclen)
should be defined in Modules/io_files.f90

- ^M removed from pseudo files
- wavefunctions arrais moved to module
wavefunctions_module, common to all codes
this is required to reduce duplicated subroutine
- new lapack subroutine, called from PWCOND,
added to lib/lapack.f lib/lapack_ibm.f

contributed by Adriano Mosca Conte,
added to the repository.
The non collinear code has required
a new module "wavefunctions" containing
"psic" and "evc", that no longer belong
to pwcom.
use: cvs update -d
there's a new example (example13), that is not
yet complete, I'm waiting for the appropriate
pseudopotential from Adriano
