P1076 Minutes from September 10, 2020

Attendees

  • Jim Lewis, Unai Martinez-Corral, Peter Ladow, Peter Flake

Meeting Discussion

  • DPI
    • Attribute EXPORT vs FOREIGN: it's ok to have two separate attributes, for making it explicit, albeit slightly redundant.
    • We agree that providing a standardized C header for defining fat pointers is desirable. However, we need feedback from vendors.
    • The FFI/DPI interface will NOT be part of VHPI, but a separate interface. However, data type conversions, specially of simple types, will be shared. That is, section 22.2 of the current LRM.
    • We discussed about variables of modes `out` or `inout` and about passing signals. These, along with supporting `wait` statements in foreign functions does require a further thought.
      • The first version might just not support either `wait` statements or signals, but only variables or constants. However, we should consider other features too, so we avoid future breaking changes.
    • PeterLadow proposed all symbols to be exported and imported automatically, through name mangling, as in C++.
