[LLVMdev] Performance problems with FORTRAN allocatable arrays
I've noticed that LLVM does a bad job of optimizing array indexing
code for FORTRAN arrays declared using the ALLOCATABLE keyword.
For example if you have something like the following:
DOUBLE PRECISION,ALLOCATABLE,DIMENSION(:,:,:,:) :: QAV
...
ALLOCATE( QAV( -2:IMAX+2,-2:JMAX+2,-2:KMAX+2,ND) )
...
DO L = 1, 5
DO K = K1, K2
DO J = J1, J2
DO I = I1, I2
II = I +
