Hi Jerry,shouldn't that be dg-do link in testcase? Does dg-do compile also link? Regards, Andre Andre Vehreschild
I adjusted the ChangeLog and changed the dg-do compilke to dg-do link. Retested all. Thanks for comment. Jerry Pending on approval. --- snip --- commit 0f7a6f628a6b9f09a663a064477da4d747a776a1 (HEAD -> master) Author: Jerry DeLisle <[email protected]> Date: Sat May 9 11:49:21 2026 -0700 fortran: Add -fcoarray=shared option to auto-link -lcaf_shmem The new -fcoarray=shared option provides a convenient shorthand for the common invocation -fcoarray=lib -lcaf_shmem. The driver transforms -fcoarray=shared into -fcoarray=lib for the frontend and automatically appends -lcaf_shmem to the link command. Existing uses of -fcoarray=lib are unaffected. Assisted by: Claude Sonnet 4.6 gcc/: * flag-types.h (gfc_fcoarray): Add GFC_FCOARRAY_SHARED. gcc/fortran/: * lang.opt (fcoarray=): Add shared enum value; update help text. * gfortranspec.cc (CAF_SHMEM_LIBRARY): New macro. (lang_specific_driver): Detect -fcoarray=shared in first pass and set need_caf_shmem flag. In second pass, transform -fcoarray=shared to -fcoarray=lib for cc1. Append -lcaf_shmem when need_caf_shmem is set and linking is active. gcc/testsuite/: * gfortran.dg/coarray_51.f90: New test. Addeed in the Assisted by words. --- snip ---diff --git a/gcc/testsuite/gfortran.dg/coarray_51.f90 b/gcc/testsuite/gfortran.dg/coarray_51.f90
