--- Comment #43 from alalaw01 at gcc dot gnu.org --- Yeah, I plan to add a fortran-specific option for this, it's easy enough, but I can't run the gfortran testsuite with that, because there are lots of C files in there too, for which the compiler doesn't accept the option... I'm having trouble writing a testcase though. My subroutine with IMPLICIT DOUBLE PRECISION (X) COMMON /MYCOMMON / X(1) produces "mycommon.x" a COMPONENT_REF, but with "mycommon" being a MEM_REF, which requires only the hunk to tree-dfa.c to handle correctly; whereas in SPEC2006, what looks to me to be equivalent FORTRAN, ends up with "mycommon" being a VAR_DECL, which requires the much-bigger patch to the fortran FE... I've very little fortran experience here, any tips? Thanks, Alan
