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: [email protected]
ReportedBy: [email protected]
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.
