Fortran 2003 Features in GNU Fortran

Implemented

See also [:GFortran#news: GFortran news] and in the [:GFortran#manuals: GNU Fortran manuals] and note that the following list is incomplete.

Unimplemented

Features supported by several other compilers

With pending patches

Without pending patches

Other features

Note: This list is by far incomplete.

  • More allowed initialization expressions [http://gcc.gnu.org/PR29962 PR29962]

  • MIN / MAX with character arguments [http://gcc.gnu.org/PR29828 PR29828]

  • Non-initialization expr. as case-selector [http://gcc.gnu.org/PR25104 PR25104]

  • type-spec for array constructor [http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27997 PR27997]

  • Type-bound procedures: PROCEDURE, GENERIC

  • Abstract derived types: ABSTRACT, DEFERRED

  • ALLOCATE specifiers SOURCE= and ERRMSG=

  • SELECTED_CHAR_KIND

  • Pointer Rank Remapping [http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29785 PR29785]

  • ASSOCIATE construction

  • Optional KIND= specifier: ACHAR, COUNT, IACHAR, ICHAR, INDEX, LBOUND, LEN, LEN_TRIM, MAXLOC, MINLOC, SCAN, SHAPE, SIZE, UBOUND, VERIFY (complete?)

  • BOZ with int(), real(), dbl(), cmpl() (incl. kind parameter) [http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29471 PR29471] [http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18026 PR18026]

    • This clashes with the extension to allow integer BOZ everywhere; current gfortran real(z'FFFF') is equivalent to Fortran 2003's real(int(z'FFFF',kind=maxKindNeeded)). Intel's solution is to give a warning (-stand f95) that in Fortran 2003 this would be differently interpreted. [Probably one could also give a warning for -std=f2003]. The next question is how to interprete real(BOZ), probably the same as data /realvariable/ (not supported yet); our result should match the result of other compilers.
