Subject: [Bug debug/103315] New: Gfortran DW_AT_Rank expression not emitting correct rank value.
Date: Thu, 18 Nov 2021 13:53:59 +0000	[thread overview]
Message-ID: <bug-103315-4@http.gcc.gnu.org/bugzilla/> (raw)

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=103315

            Bug ID: 103315
           Summary: Gfortran DW_AT_Rank expression not emitting correct
                    rank value.
           Product: gcc
           Version: og10 (devel/omp/gcc-10)
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: debug
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rupesh.potharla at amd dot com
  Target Milestone: ---

I am working on to implement Assumed rank in gdb. Evaluating DW_AT_RANK
attribute expression provided by gcc is not emitting the correct rank value. Do
we have to manipulate the value returned by the expression in any way to get
the exact rank value? 

----------------------------------------------------------------------------
PROGRAM  arank

REAL :: a1(10)

call test_rank(a1)

CONTAINS
  SUBROUTINE test_rank(a)
    REAL :: a(..)
    PRINT *, RANK(a)
  END

END PROGRAM arank

------------------------------------------------------------------------------
gfortran -gdwarf-5 arank.f90 -o arank
------------------------------------------------------------------------------

DW_AT_rank      (DW_OP_push_object_address, DW_OP_plus_uconst 0x1c,
DW_OP_deref)
