[Patch, fortran] PR32315 - DATA with implied-do: Bounds checks missing [regression vs. g77]

[Paul Richard Thomas]

:ADDPATCH fortran:

Here is what is getting to be a very rare beast - a regression with
respect to g77.  Adding the requisite bounds checking was very
straightforward, as will be seen from the patch.  Note that the
arrayspec from the gfc_ref is used, rather than the symbol's
array_spec - I got caught with this.  To see why, take a look at
gfortran.fortran-torture/compile/data.f90.

Regtested on Cygwin_NT/amd64 - OK for trunk after a spin on x86_ia64/FC8?

Cheers

Paul
