/* Parse a C expression from text in a string,
|
|
|
|
|
and return the result as a struct expression pointer.
|
|
|
|
|
That structure contains arithmetic operations in reverse polish,
|
|
|
|
|
with constants represented by operations that are followed by special data.
|
|
|
|
|
See expression.h for the details of the format.
|
|
|
|
|
What is important here is that it can be built up sequentially
|
|
|
|
|
during the process of parsing; the lower levels of the tree always
|
|
|
|
|
come first in the result.
|
|
|
|
|
|
|
|
|
|
Note that malloc's and realloc's in this file are transformed to
|
|
|
|
|
xmalloc and xrealloc respectively by the same sed command in the
|
|
|
|
|
makefile that remaps any other malloc/realloc inserted by the parser
|
|
|
|
|
generator. Doing this with #defines and trying to control the interaction
|
|
|
|
|
with include files (<malloc.h> and <stdlib.h> for example) just became
|
|
|
|
|
too messy, particularly when such includes can be inserted at random
|
|
|
|
|
times by the parser generator. */

/* FIXME: carlton/2003-09-25: This next bit leads to lots of
|
|
|
|
|
reduce-reduce conflicts, because the parser doesn't know whether or
|
|
|
|
|
not to use qualified_name or qualified_type: the rules are
|
|
|
|
|
identical. If the parser is parsing 'A::B::x', then, when it sees
|
|
|
|
|
the second '::', it knows that the expression to the left of it has
|
|
|
|
|
to be a type, so it uses qualified_type. But if it is parsing just
|
|
|
|
|
'A::B', then it doesn't have any way of knowing which rule to use,
|
|
|
|
|
so there's a reduce-reduce conflict; it picks qualified_name, since
|
|
|
|
|
that occurs earlier in this file than qualified_type.
|
|
|
|
|
|
|
|
|
|
There's no good way to fix this with the grammar as it stands; as
|
|
|
|
|
far as I can tell, some of the problems arise from ambiguities that
|
|
|
|
|
GDB introduces ('start' can be either an expression or a type), but
|
|
|
|
|
some of it is inherent to the nature of C++ (you want to treat the
|
|
|
|
|
input "(FOO)" fairly differently depending on whether FOO is an
|
|
|
|
|
expression or a type, and if FOO is a complex expression, this can
|
|
|
|
|
be hard to determine at the right time). Fortunately, it works
|
|
|
|
|
pretty well in most cases. For example, if you do 'ptype A::B',
|
|
|
|
|
where A::B is a nested type, then the parser will mistakenly
|
|
|
|
|
misidentify it as an expression; but evaluate_subexp will get
|
|
|
|
|
called with 'noside' set to EVAL_AVOID_SIDE_EFFECTS, and everything
|
|
|
|
|
will work out anyways. But there are situations where the parser
|
|
|
|
|
will get confused: the most common one that I've run into is when
|
|
|
|
|
you want to do
|
|
|
|
|
|
|
|
|
|
print *((A::B *) x)"
|
|
|
|
|
|
|
|
|
|
where the parser doesn't realize that A::B has to be a type until
|
|
|
|
|
it hits the first right paren, at which point it's too late. (The
|
|
|
|
|
workaround is to type "print *(('A::B' *) x)" instead.) (And
|
|
|
|
|
another solution is to fix our symbol-handling code so that the
|
|
|
|
|
user never wants to type something like that in the first place,
|
|
|
|
|
because we get all the types right without the user's help!)
|
|
|
|
|
|
|
|
|
|
Perhaps we could fix this by making the lexer smarter. Some of
|
|
|
|
|
this functionality used to be in the lexer, but in a way that
|
|
|
|
|
worked even less well than the current solution: that attempt
|
|
|
|
|
involved having the parser sometimes handle '::' and having the
|
|
|
|
|
lexer sometimes handle it, and without a clear division of
|
|
|
|
|
responsibility, it quickly degenerated into a big mess. Probably
|
|
|
|
|
the eventual correct solution will give more of a role to the lexer
|
|
|
|
|
(ideally via code that is shared between the lexer and
|
|
|
|
|
decode_line_1), but I'm not holding my breath waiting for somebody
|
|
|
|
|
to get around to cleaning this up... */

Change symbols for C++ nested types to contain the fully qualified
name, if possible. (At least in the DWARF-2 case.) Partial fix
for PR's c++/57, c++/488, c++/539, c++/573, c++/609, c++/832,
c++/895.
* c-exp.y: Update copyright:
(qualified_type): Handle types nested within classes.
* cp-namespace.c: Update comments.
(cp_set_block_scope): Delete #if 0.
(cp_lookup_nested_type): Handle types nested within classes.
* dwarf2read.c: (scan_partial_symbols): Call add_partial_structure
when appropriate.
(add_partial_symbol): Add the name of the enclosing namespace to
types.
(pdi_needs_namespace): New.
(add_partial_namespace): Tweak comment.
(add_partial_structure): New.
(psymtab_to_symtab_1): Initialize processing_current_prefix
here...
(process_die): instead of here.
(read_structure_scope): Try to figure out the name of the class or
namespace that the structure might be defined within.
(read_enumeration): Generate fully-qualified names, if possible.
(read_namespace): Don't set name to NULL.
(die_specification): New.
(new_symbol): Generate fully-qualified names for types.
(read_type_die): Determine appropriate prefix.
(determine_prefix): New.
(typename_concat): New.
(class_name): New.
* valops.c: Update copyright.
(value_aggregate_elt): Pass NOSIDE to
value_struct_elt_for_reference.
(value_struct_elt_for_reference): Make static, add NOSIDE
parameter, call value_maybe_namespace_elt as a last resort.
(value_namespace_elt): Break out code into
value_maybe_namespace_elt.
(value_maybe_namespace_elt): New.
2004-01-14 David Carlton <carlton@kealia.com>
* gdb.cp/namespace.exp: Add tests involving classes defined within
namespaces.
