The rank and shape of the dummy argument are the rank and shape of the corresponding actual argument. If the rank is nonzero, the lower and upper bounds of the dummy argument are those that would be given by the intrinsic functions LBOUND and UBOUND respectively if applied to the actual argument, except that when the actual argument is assumed-size, the upper bound of the last dimension of the dummy argument is 2 less than the lower bound of that dimension. (section 12.5.2.4, paragraph 15) Here is a small test program: program assumedrank implicit none real,dimension(:,:,:),allocatable :: bb real,dimension(3:9,10:15,16:32) :: c allocate(bb(3:9,10:15,16:32)) print*, 'Actual argument, allocatable, lbound=',lbound(bb) call p(bb) print*, 'Actual argument, lbound=',lbound(c) call p(c) contains subroutine p(a) real,dimension(..) :: a print*,'Dummy argument, lbound=',lbound(a) end subroutine p end gfortran 5.2.0 returns 1 1 1 as the lower bounds, both for the allocatable and the fixed-shape array. ^ permalink raw reply [flat|nested] 5+ messages in thread

Same thing happens for avx512f-vcvt?si2*.c tests (but error message is slightly different): operand type mismatch for `vcvt?si2*'. The reason is that GCC emits an insn with rounding/SAE specifier in a wrong place. ^ permalink raw reply [flat|nested] 5+ messages in thread
