peter klausler	d56fdc8e95	[flang][msvc] Avoid dependence on long double ... MSVC does not support a distinct 80-bit extended precision "long double" type. Rework the I/O runtime to avoid using native C/C++ type names. Centralize the mappings between the KIND= type parameters of REAL and their binary precisions in the common real.h header file, and use KIND type parameter values rather than binary precisions for clarity where appropriate. This patch, if successful, should obviate the need for Differential review D88511. (This patch anticipates a successful review of D88688, which fixes the function that maps each kind of real to its maximum number of significant decimal digits.)

peter klausler	0c3c8f4ae6	[flang] Fix descriptor-based array data item I/O for list-directed CHARACTER & LOGICAL ... These types have to distinguish list-directed I/O from formatted I/O, and the subscript incrementation call was in the formatted branch of the if() rather than after the if().

peter klausler	5c9aca1e93	[flang] Descriptor-based I/O using wrong size for contiguous unformatted I/O ... The descriptor-based I/O routine was using the size of the descriptor rather than the size of the described data for the transfer. Fix, and add a comment to the relevant API.

peter klausler	cc01194c2f	[flang] Descriptor-based I/O data item transfers ... Add support for OutputDescriptor() and InputDescriptor() in the I/O runtime. Change existing scalar formatted I/O functions to drive descriptor-based I/O routines internally. Differential Revision: https://reviews.llvm.org/D85491	2020-08-07 13:09:09 -07:00
