2019-11-08Allow CHARACTER literals in assignments and data statements.Mark Eggleston1-6/+11
Allows character literals to used to assign values to non-character variables in the same way that Hollerith constants are used. In addition character literals can be used in data statements just like Hollerith constants. Warnings of such use are output to discourage this usage as it is a non-standard legacy feature and must be explicitly enabled. Enabled by -fdec and -fdec-char-conversions.

2017-12-17Support -std=f2018Janne Blomqvist1-29/+33
The Fortran committee has decided to rename the upcoming Fortran 2015 standard to Fortran 2018. This is not a reflection of a three year delay in the process, but rather they are following other standards in adopting the year of publication for the name. For more details see N2144. This patch renames GFC_STD_F2015 to GFC_STD_F2018, and makes it a separate flag rather than an alias for GFC_STD_GNU. Also, it adds a -std=f2018 argument, and documents it.
