2007-07-24 Thomas Koenig <tkoenig@gcc.gnu.org> PR fortran/30814 * trans-decl.c (generate_function_code): Add argument for flag_bounds_check to the array for set_options. * invoke.texi: Mention that some checks require -fbounds-check to be set during compilation of the main program. 2007-07-24 Thomas Koenig <tkoenig@gcc.gnu.org> PR fortran/30814 * libgfortran.h: Add bounds_check to compile_options_t. * runtime/compile_options.c (set_options): Add handling of compile_options.bounds_check. * intrinsics/pack_generic.c (pack_internal): Also determine the number of elements if compile_options.bounds_check is true.

In the future this may also include other forms of checking, e.g., checking
substring references.
