Bug #: 56226 Summary: Add support for DEC UNION and MAP extensions Classification: Unclassified Product: gcc Version: unknown Status: UNCONFIRMED Severity: enhancement Priority: P3 Component: fortran AssignedTo: unassig...@gcc.gnu.org ReportedBy: russelljbren...@gmail.com Porting old f77 code for use with gfortran is fairly straightforward, even for most extensions. The UNION and MAP extensions thusfar prove impossible to port without modifying the UDT interface. Existing compilers can candle these extensions (intel ifort and portland group) but there is no open source alternative available afaik. UNIONs and MAPs are widely lamented exclusions of the later fortran standards. Addition of support for these extensions would facilitate automated conversion of much existing code to gfortran-compatible code.
