Dear Fortranners,
specifying invalid constant array declarations (e.g. real array bounds)
could lead to an ICE because the array specs were checked for consistency.
A possible solution is to try an early simplification before doing that
check and was suggested by Steve.
However, regtesting did reveal that bad declarations involving e.g.
arithmetic errors - like division by zero - were now handled differently.
(The relevant testcase was gfortran.dg/arith_divide_2.f90).
I therefore added a new function gfc_try_simplify_expr that accepts the
simplification only if no error occurs. This allows discovery of
arithmetic errors also at later stages and will be used here.
Regtested on x86_64-pc-linux-gnu. OK for mainline?
OK. Thanks
