There is a CLI command 'complete' intended to use with emacs. Such a command
would also be useful for MI frontends, when separate CLI and MI channels cannot
be used. For example, on Windows (because of lack of PTYs) or when GDB is used
through SSH session.
This commit adds a new '-complete' MI command.

This error happens as follows.
The function find_partial_die has a cu argument, but returns a pdi which may
or may not be from that cu:
...
/* Find a partial DIE at OFFSET, which may or may not be in CU,
except in the case of .debug_types DIEs which do not reference
outside their CU (they do however referencing other types via
DW_FORM_ref_sig8). */
static struct partial_die_info *
find_partial_die (sect_offset sect_off, int offset_in_dwz, struct dwarf2_cu *cu)
...
So the pdi returned by find_partial_die here in partial_die_parent_scope may
be from another cu:
...
partial_die_parent_scope (struct partial_die_info *pdi,
struct dwarf2_cu *cu)
{
const char *grandparent_scope;
struct partial_die_info *parent, *real_pdi;
/* We need to look at our parent DIE; if we have a DW_AT_specification,
then this means the parent of the specification DIE. */
real_pdi = pdi;
while (real_pdi->has_specification)
real_pdi = find_partial_die (real_pdi->spec_offset,
real_pdi->spec_is_dwz, cu);
parent = real_pdi->die_parent;
...
in which case both real_pdi and parent will be not from cu, but from another
one, say cu2.
Subsequently, cu's comp_unit_obstack is used to set parent->scope:
...
parent->scope = typename_concat (&cu->comp_unit_obstack,
grandparent_scope,
parent->name, 0, cu);
...
So, we use cu->comp_unit_obstack to assign a value to the scope field of
a pdi belonging to cu2, and when cu is deleted, the scope field points to a
freed value.
Fix this by making find_partial_die return the cu corresponding to the
returned pdi, and handling this at the call sites.
Tested on x86_64-linux.

(partial_die_info::fixup): Handle new return type of find_partial_die.
This patch simplifies the code of
stap-probe.c:stap_parse_register_operand by making "regname" an
std::string. No functionality change.
I'm this code's maintainer, so I'm pushing this as it's a fairly
trivial patch.

* stap-probe.c (stap_parse_register_operand): Make "regname" an
"std::string", simplifying the algorithm.
I think the string formatting for complaints was messed up by Tom's
patch to simplify the complaint mechanism. This small and trivial
patch fixes them.
Pushed as obvious.
gdb/ChangeLog:

(stap_static_probe_ops::get_probes): Likewise.
This patch contains three very small improvement on the logic of some
operations we do on stap-probe.c. They don't change what the code
does.
Pushed as obvious.

"gdbarch_stap_parse_special_token_p" and
"gdbarch_stap_parse_special_token" in the same "if" statement.
Invert check when verifying for operation on register
displacement.
Some functions's comments were not entirely correct on stap-probe.c,
so this patch updates them.
