Yao Qi cc977dc7d5 Use get_frame_register_value instead of deprecated_frame_register_read
This patch calls get_frame_register_value instead of
deprecated_frame_register_read, so that we can pass
value_contents_for_printing to val_print.  Both
get_frame_register_value and deprecated_frame_register_read call
frame_unwind_register_value indirectly, so no functionality is changed
by this patch.

	* mt-tdep.c (mt_registers_info): Call
	get_frame_register_value instead of
	deprecated_frame_register_read.
	* sh64-tdep.c (sh64_do_register): Likewise.

Pedro Alves 3cde5c42d1 Eliminate agent_expr_p; VEC -> std::vector in struct bp_target_info
After the previous patch, we end up with these two types with quite
similar, and potentially confusing names:

  typedef gdb::unique_ptr<agent_expr> agent_expr_up;

  /* Pointer to an agent_expr structure.  */
  typedef struct agent_expr *agent_expr_p;

The latter is only necessary to put agent_expr pointers in VECs.  So
just eliminate it and use std::vector instead.

gdb/ChangeLog:

	* ax.h (agent_expr_p): Delete.
	(DEF_VEC_P (agent_expr_p)): Delete.

Pedro Alves 833177a4a5 'struct agent_expr *' -> unique_ptr<agent_expr>
This patch makes the gen_* functions return a unique_ptr instead of
raw pointer:

  typedef gdb::unique_ptr<agent_expr> agent_expr_up;

and then adjusts the codebase throughout to stop using
make_cleanup_free_agent_expr.

The cond_bytecode and cmd_bytecode fields of struct bp_location are
owning pointers, so they're changed to be unique_ptr's instead of raw
pointers.

Pedro Alves 2f408ecb92 Use ui_file_as_string throughout more
This replaces most of the remaining ui_file_xstrdup calls with
ui_file_as_string calls.  Whenever a call was replaced, that led to a
cascade of other necessary adjustments throughout, to make the code
use std::string instead of raw pointers.  And then whenever I added a
std::string as member of a struct, I needed to adjust
allocation/destruction of said struct to use new/delete instead of
xmalloc/xfree.

The stopping point was once gdb built again.  These doesn't seem to be
a way to reasonably split this out further.

Maybe-not-obvious changes:

 - demangle_for_lookup returns a cleanup today.  To get rid of that,
   and avoid unnecessary string dupping/copying, this introduces a
   demangle_result_storage type that the caller instantiates and
   passes to demangle_for_lookup.

 - Many methods returned a "char *" to indicate that the caller owns
   the memory and must free it.  Those are switched to return a
   std::string instead.  Methods that return a "view" into some
   internal string return a "const char *" instead.  I.e., we only
   copy/allocate when necessary.

Pedro Alves aaee65aea2 Use ui_file_as_string in gdb/compile/
Using ui_file_as_string would imply changing a few prototypes to pass
around source and object file names as std::string.  Instead of that,
wrap those two in a new class.  This ends up eliminating a small
wrinkle: get_new_file_names and compile_object_load have swapped
parameters.  The former takes "source, objfile", while the latter
takes "objfile, source".

Pedro Alves 1f45808ead Clean up tracepoint.h/c:collection_list
Noticed we could do this while working on the expression_up change.

The main goal here was getting rid of the
encode_actions_and_make_cleanup / do_clear_collection_list cleanups.

While at it, uncrustify the code:

 - Make collection_list a C++ class, with data members private (and
   thus renamed m_...).

 - Make related functions be member methods.

 - Use std::vector instead of an open coding a vector implementation.

 - Use std::sort instead of qsort.

 - Rename the "list" member of collection_list, which is an incredibly
   obfuscating name.

 - Rename a couple other things here and there for clarify.

Pedro Alves 8de00631b8 Introduce ui_file_as_string
ui_file_as_string is a variant of ui_file_xstrdup that returns a
std::string instead of a xmalloc'ed char *.  The idea is using the new
function to eliminate "make_cleanup (xfree, ...)"  cleanups
throughout.

Following patches will make use of this.

Pedro Alves 4d01a485d2 'struct expression *' -> gdb::unique_xmalloc_ptr<expression>
This patch makes parse_expression and friends return a unique_ptr
instead of raw pointer [1]:

  typedef gdb::unique_malloc_ptr<expression> expression_up;

and then adjusts the codebase throughout to stop using cleanups to
manage lifetime of expression pointers.

Whenever I found a structure owning an expression pointer, I made it
store a unique_ptr instead of a raw pointer, which then requires using
new/delete of the holding structure, instead of XNEW/xfree.

[1] - I'd like to set the rule that types named with an "_up" suffix
      are unique_ptr typedefs.

Note I used gdb::unique_xmalloc_ptr instead of gdb::unique_ptr, simply
because we still use xmalloc instead of new to allocate expression
objects.  Once that's changed, all we need to do is change the
expression_up typedef and the smart pointer will then call delete
instead of xfree.

Pedro Alves 896b6bda69 breakpoint.c:commands_command_1 constification and cleanup
This is constification needed for next patch.  Adjust
commands_command_1 to use std::string too because the "arg" parameter
is currently overwritten and then passed to make_cleanup.  The
constification alone would trigger a compile error in the make_cleanup
call otherwise (passing const char * to void * parameter).  Using
std::string gets rid of the cleanup in the first place, resulting in
simpler code.

Lionel Flandrin 9dc193c3be Check for truncated registers in process_g_packet
While investigating an unrelated issue in remote.c I noticed that the
bound checking for 'g' packets was bogus:

The previous code would only check that the first byte of the register
was within bounds before passing the buffer to regcache_raw_supply.
If it turned out that the register in the 'g' packet was incomplete
then regcache_raw_supply would proceed to memcpy out-of-bounds.

Since the buffer is allocated with alloca it's relatively unlikely to
crash (you just end up dumping gdb's stack into the cache) but it's
still a bit messy.

I changed this logic to check for truncated registers and raise an
error if one is encountered.  Hopefully it should make debugging
remote stubs a bit easier.
