The fix for bug 59195:
[C++ demangler handles conversion operator incorrectly]
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=59195
unfortunately makes the demangler crash due to infinite recursion, in
case of casts in template parameters.
For example, with:
template<int> struct A {};
template <typename Y> void function_temp(A<sizeof ((Y)(999))>) {}
template void function_temp<int>(A<sizeof (int)>);
The 'function_temp<int>' instantiation above mangles to:
_Z13function_tempIiEv1AIXszcvT_Li999EEE
The demangler parses this as:
typed name
template
name 'function_temp'
template argument list
builtin type int
function type
builtin type void
argument list
template (*)
name 'A'
template argument list
unary operator
operator sizeof
unary operator
cast
template parameter 0 (**)
literal
builtin type int
name '999'
And after the fix for 59195, due to:
static void
d_print_cast (struct d_print_info *dpi, int options,
const struct demangle_component *dc)
{
...
/* For a cast operator, we need the template parameters from
the enclosing template in scope for processing the type. */
if (dpi->current_template != NULL)
{
dpt.next = dpi->templates;
dpi->templates = &dpt;
dpt.template_decl = dpi->current_template;
}
when printing the template argument list of A (what should be "<sizeof
(int)>"), the template parameter 0 (that is, "T_", the '**' above) now
refers to the first parameter of the the template argument list of the
'A' template (the '*' above), exactly what we were already trying to
print. This leads to infinite recursion, and stack exaustion. The
template parameter 0 should actually refer to the first parameter of
the 'function_temp' template.
Where it reads "for the cast operator" in the comment in d_print_cast
(above), it's really talking about a conversion operator, like:
struct A { template <typename U> explicit operator U(); };
We don't want to inject the template parameters from the enclosing
template in scope when processing a cast _expression_, only when
handling a conversion operator.
The problem is that DEMANGLE_COMPONENT_CAST is currently ambiguous,
and means _both_ 'conversion operator' and 'cast expression'.
Fix this by adding a new DEMANGLE_COMPONENT_CONVERSION component type,
which does what DEMANGLE_COMPONENT_CAST does today, and making
DEMANGLE_COMPONENT_CAST just simply print its component subtree.
I think we could instead reuse DEMANGLE_COMPONENT_CAST and in
d_print_comp_inner still do:
@@ -5001,9 +5013,9 @@ d_print_comp_inner (struct d_print_info *dpi, int options,
d_print_comp (dpi, options, dc->u.s_extended_operator.name);
return;
case DEMANGLE_COMPONENT_CAST:
d_append_string (dpi, "operator ");
- d_print_cast (dpi, options, dc);
+ d_print_conversion (dpi, options, dc);
return;
leaving the unary cast case below calling d_print_cast, but seems to
me that spliting the component types makes it easier to reason about
the code.
g++'s testsuite actually generates three symbols that crash the
demangler in the same way. I've added those as tests in the demangler
testsuite as well.
And then this fixes PR other/61233 too, which happens to be a
demangler crash originally reported to GDB, at:
https://sourceware.org/bugzilla/show_bug.cgi?id=16957
Bootstrapped and regtested on x86_64 Fedora 20.
Also ran this through GDB's testsuite. GDB will require a small
update to use DEMANGLE_COMPONENT_CONVERSION in one place it's using
DEMANGLE_COMPONENT_CAST in its sources.

A call to demangle_template might allocate storage within a temporary
string even if the call to demangle_template eventually returns
failure.
This will never cause the demangler to crash, but does leak memory, as
a result I've not added any tests for this.
Calling string_delete is safe, even if nothing is allocated into the
string, the string is initialised with string_init, so we know the
internal pointers are NULL.

The hashtab pointer hash function is not very good. It throws most of the
bits in the pointer away.
This changes pointer_hash to use the mix code from jhash function that mixes
all the bits on the pointer and makes them dependent on each other, before doing
the modulo.

using the "comm" process name, which is reported in top.
