Bug ID: 82525
Summary: [GRAPHITE] codegen error for modulo operations we
cannot represent
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: rguenth at gcc dot gnu.org
Blocks: 59859
Target Milestone: ---
We generate modulo constraints to represent conversions / unsigned operations.
With Fortran array-descriptors we run into codegen issues when those are not
elided by ISL itself and the original type matches the type we use for ISL IVs.
module OPMATRIX_MODULE
implicit none
type opmatrix_type
real(kind=kind(1.0d0)), dimension(:,:), pointer :: restricted
end type
interface zero_
module procedure zero
end interface
contains
subroutine zero(self)
type(opmatrix_type) :: self
self%restricted = 0.0d0
end subroutine
end
