re PR fortran/90903 (Implement runtime checks for bit manipulation intrinsics)
2019-07-16 Harald Anlauf <anlauf@gmx.de>
PR fortran/90903
* libgfortran.h: Add mask for -fcheck=bits option.
* options.c (gfc_handle_runtime_check_option): Add option "bits"
to run-time checks selectable via -fcheck.
* trans-intrinsic.c (gfc_conv_intrinsic_btest)
(gfc_conv_intrinsic_singlebitop, gfc_conv_intrinsic_ibits)
(gfc_conv_intrinsic_shift, gfc_conv_intrinsic_ishft)
(gfc_conv_intrinsic_ishftc): Implement run-time checks for the
POS, LEN, SHIFT, and SIZE arguments.
* gfortran.texi: Document run-time checks for bit manipulation
intrinsics.
* invoke.texi: Document new -fcheck=bits option.
PR fortran/90903
* gfortran.dg/check_bits_1.f90: New testcase.
