Description Tobias Burnus 2024-06-21 09:53:49 UTC 
Using  map(/common/)  is rejected in gfortran but is valid:

   10 |    !$omp target enter data map(/mycommon/)
      |                                1
Error: Syntax error in OpenMP variable list at (1)

( Example from PR fortran/115559
  Please update libgomp.fortran/declare-target-link-2.f90 once fixed )

subroutine one
   integer :: A(2),C
   real :: B
   common /mycommon/ A,B,C
   !$omp declare target link(/mycommon/)

   A = [1,2]; B = 2.0; C = 7
   !$omp target enter data map(/mycommon/)
end
Comment 1 Tobias Burnus 2024-07-29 09:59:14 UTC 
From the other issue, now fixed:

(B) Issues found when writing a testcase:

* COMMON blocks: Using map(a,b,c) instead of map(/mycommon/) fails with:
     error: undefined symbol: mycommon_
  TESTCASE: attachment 58478 [details]


ISSUE (A) is (→ comment 0):

   10 |    !$omp target enter data map(/mycommon/)
      |                                1
Error: Syntax error in OpenMP variable list at (1)
