Bug #: 52606
Summary: Confusing diagnostics for long identifiers
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: anl...@gmx.de
Excessively long identifiers can produce quite confusing diagnostics.
Perhaps error recovery could be improved.
Example:
module gfcbug118
implicit none
interface foo
module procedure very_long_identifier_beyond_31char
end interface
contains
subroutine very_long_identifier_beyond_31char ()
end subroutine very_long_identifier_beyond_31char
end module gfcbug118
% gfc gfcbug118.f90 -std=f95
gfcbug118.f90:4.54:
module procedure very_long_identifier_beyond_31char
1
Error: Name at (1) is too long
gfcbug118.f90:7.45:
subroutine very_long_identifier_beyond_31char ()
1
Error: Name at (1) is too long
gfcbug118.f90:8.5:
end subroutine very_long_identifier_beyond_31char
1
Error: Expecting END MODULE statement at (1)
gfcbug118.f90:9.20:
end module gfcbug118
1
Error: Fortran 2008: CONTAINS statement without FUNCTION or SUBROUTINE
statement at (1)
% gfc gfcbug118.f90 -fmax-identifier-length=31
gfcbug118.f90:4.54:
module procedure very_long_identifier_beyond_31char
1
Error: Name at (1) is too long
gfcbug118.f90:7.45:
subroutine very_long_identifier_beyond_31char ()
1
Error: Name at (1) is too long
gfcbug118.f90:8.5:
end subroutine very_long_identifier_beyond_31char
1
Error: Expecting END MODULE statement at (1)
