Fortran: Intel vs G77

[David Lecomber <david at streamline-computing dot com>]

The current situation with g77 and Intel meets gdb is as follows for
multi-dim arrays

Intel compiled code:
  whatis -- wrong way round real(4 * 5 ) is reported as real (5 * 4)
  indexing -- correct 
  print elements -- boundaries not aligned properly ( it prints a 5 * 4 
as a 4 * 5 )


g77 fortran compilers compiled code:
  whatis -- correct
  print elements -- correct
  indexing -- 'print A(1,2)' will get the wrong answer.

So, unless there is a method to check what the compiler was used, we are
left with

  1. status quo
or
  2. compile up two different versions -- one for gdb + intel, the
other for gdb + g77

Does anyone know of the existence of such a check?

Patches to fix the three issues are attached, but of course they
cannot all be applied at once; the fix to make g77 work will bust
intel, and vice-versa..
