[Bug fortran/30887] %VAL only accepts default-kind integer/real/complex
--- Comment #7 from p dot w dot draper at durham dot ac dot uk 2007-02-23 15:44 --- Tried out the patch and it works for me under 64bit with default sized integers. Seems to have fixed PR 30888 too. Thanks. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30887
[Bug fortran/30888] New: %VAL construct fails with argument procedures
When calling procedures which are passed as arguments to a subroutine the %VAL construct has inconsistent behaviour. Consider the following code: SUBROUTINE VALTEST( DOIT ) EXTERNAL DOIT INTEGER P INTEGER I I = 0 P = 0 CALL DOIT( %VAL( P ) ) CALL DOIT( I ) CALL DOIT( %VAL( P ) ) END > gfortran -c valtest.f valtest.f:9.22: CALL DOIT( %VAL( P ) ) 1 Error: By-value argument at (1) is not allowed in this context which is an error caused by the second identical call to DOIT(%VAL(P)). -- Summary: %VAL construct fails with argument procedures Product: gcc Version: 4.3.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: p dot w dot draper at durham dot ac dot uk GCC host triplet: x86_64-unknown-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30888
[Bug fortran/30887] New: %VAL construct fails on 64 bit
The %VAL construct doesn't accept INTEGER types with a size greater than the default kind. This is essential for supporting 64 bit architectures where an address cannot be stored in an integer with the default kind. Consider the simple module: SUBROUTINE VALTEST2() INTEGER*8 P P = 0 CALL DOIT( %VAL( P ) ) END That fails with error report: > gfortran -c valtest2.f valtest2.f:6.22: CALL DOIT( %VAL( P ) ) 1 Error: Kind of by-value argument at (1) is larger than default kind Increasing the size of the default integer kind would resolve this problem, but that would have secondary issues (which are not acceptable in my code, the default integer maps to a defined-size storage type). -- Summary: %VAL construct fails on 64 bit Product: gcc Version: 4.3.0 Status: UNCONFIRMED Severity: critical Priority: P3 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: p dot w dot draper at durham dot ac dot uk GCC host triplet: x86_64-unknown-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30887
[Bug fortran/23074] g77-style typeless BOZ constants not implemented
--- Additional Comments From p dot w dot draper at durham dot ac dot uk 2005-07-26 13:28 --- Andrew, I've said this is related to bug 18026, rather than a duplicate, as the actual format used for these typeless BOZ constants is none standard and not the same as in bug 18026. As in gfortran, g77 typed constants have the format X'', whereas these are ''X, the difference may not be apparent at first glance. If you missed this point please reopen or merge this report. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23074
[Bug fortran/23074] New: g77-style typeless BOZ constants not implemented
In g77 you define a typeless BOZ constant that can be assigned to any other
type, using the formats ''X, ''Z etc. This allows PARAMETERs to be
defined like:
PROGRAM TLBOZ
DOUBLE PRECISION inf, nan
PARAMETER ( inf = '7FF0'Z )
PARAMETER ( nan = 'FFF8'X )
print *, inf, nan
END
The relevant g77 description is at:
http://gcc.gnu.org/onlinedocs/gcc-3.4.1/g77/Constants.html
This is related to bug 18026.
