2018-02-23PR 84519 Handle optional QUIET specifier for STOP and ERROR STOPJanne Blomqvist1-8/+11
Fortran 2018 adds a new QUIET specifier for the STOP and ERROR STOP statements, in order to suppress the printing of signaling FP exceptions and the stop code. This patch adds the necessary library changes, but for now the new specifier is not parsed and the frontend unconditionally adds a false value for the new argument.

2018-02-22Character length cleanup for Coarray Fortran libraryJanne Blomqvist1-14/+14
Following the change to use size_t for Fortran character lengths (PR 78534), this patch modifies the Coarray ABI in a similar way. The single-image implementation that is included in libgfortran is updated, but this needs corresponding work in the OpenCoarray library as well for multi-image support. I also fixed the types for the STOP and ERROR STOP implementation in libgfortran, as the calling of them is somewhat intertwined with the calling of the corresponding CAF functions. I'll send the OpenCoarray changes as a separate pull request to the OpenCoarrays repository.
