[PATCH] D42665: Extensions to the LLVM debug information metadata to support the Fortran language.

[xoviat via Phabricator via llvm-commits]

There are several new debug info constructs added  here.  They include the following.

!DIStringType :
Debug clients expect Fortran CHARACTER types to appear as
DW_TAG_string_type in the DWARF. !DIStringType can be used to generate
DWARF for constant and variable sized CHARACTER type variables.  If the
size of a CHARACTER must be computed at run-time, DWARF specifies that
the DW_TAG_string_type has a DW_AT_string_length with a location expression.

!DIFortranArrayType and !DIFortranSubrange :
Debug clients expect Fortran arrays to specify the bounds of their
dimensions in DW_TAG_subrange_types.  Both the lower and upper bounds can
be given by the programmer as constants, variables, a mix of constants
and variables, omitted, or as deferred.  The DWARF standard requires
that these bounds appear in the DW_TAG_subrange_type.  Debug clients
expect variable bounds to be encoded in blocks.
