Replace the two VEC fields with std::vector.

I found only one place where these lm_infos were allocated, but two
where they are freed.  It looks like solib_target_free_so missed freeing
section_bases before.

More c++ification is obviously possible, but my goal right now is to get
rid of VEC (CORE_ADDR).

I wasn't really able to test this, since the list of remote targets that use
this method of fetching solibs is quite limited (windows, dicos and
arm-symbian, from what I can see).

gdb/ChangeLog:

	* solib-target.c (struct lm_info): Add default constructor,
	delete copy constructor and operator=.
	<segment_bases, section_bases>: Change type to
	std::vector<CORE_ADDR>.
	(library_list_start_segment, library_list_start_section,
	library_list_start_library, library_list_end_library,
	solib_target_free_library_list, solib_target_free_so,
	solib_target_relocate_section_addresses): Adjust.

The fields in the description of the gdbarch interface are separated
using colons.  That becomes a problem if we want to use things like
std::vector in it. This patch changes the field separator to use
semicolons instead.

I think there's very little chance we'll ever want to use a semicolon in
one of the fields, but if you think another character would be more
appropriate, let me know.

gdb/ChangeLog:

	* gdbarch.sh: Use semi-colon as field separator instead of colon.
	* gdbarch.h: Re-generate.

The starting point of this series was to try to remove the definition of VEC
(CORE_ADDR) and fix what it breaks.

The series has been through the buildbot.  I see some failures on the AArch32
builder, but I see the same failures on previous builds, so I don't think this
series is the cause.

Simon Marchi (4):
  Change field separator in gdbarch.sh
  Change return type of gdbarch_software_single_step to
    vector<CORE_ADDR>
  Use std::vector in solib-target lm_info
  Remove definition of VEC (CORE_ADDR)

This is a relatively straightforward patch that changes
gdbarch_software_single_step so it returns an std::vector<CORE_ADDR>
instead of a VEC (CORE_ADDR).

gdb/ChangeLog:

	* gdbarch.sh (software_single_step): Change return type to
	std::vector<CORE_ADDR>.
	* gdbarch.c, gdbarch.h: Re-generate.
	* arch/arm-get-next-pcs.c (thumb_deal_with_atomic_sequence_raw):
	Adjust.
	(arm_deal_with_atomic_sequence_raw): Adjust.
	(thumb_get_next_pcs_raw): Adjust.
	(arm_get_next_pcs_raw): Adjust.
	(arm_get_next_pcs): Adjust.
	* arch/arm-get-next-pcs.h (arm_get_next_pcs): Adjust.
	* aarch64-tdep.c (aarch64_software_single_step): Adjust.
	* alpha-tdep.c (alpha_deal_with_atomic_sequence): Adjust.
	(alpha_software_single_step): Adjust.
	* alpha-tdep.h (alpha_software_single_step): Adjust.
	* arm-linux-tdep.c (arm_linux_software_single_step): Adjust.
	* arm-tdep.c (arm_software_single_step): Adjust.
	(arm_breakpoint_kind_from_current_state): Adjust.
	* arm-tdep.h (arm_software_single_step): Adjust.
	* breakpoint.c (insert_single_step_breakpoint): Adjust.
	* cris-tdep.c (cris_software_single_step): Adjust.
	* mips-tdep.c (mips_deal_with_atomic_sequence): Adjust.
	(micromips_deal_with_atomic_sequence): Adjust.
	(deal_with_atomic_sequence): Adjust.
	(mips_software_single_step): Adjust.
	* mips-tdep.h (mips_software_single_step): Adjust.
	* moxie-tdep.c (moxie_software_single_step): Adjust.
	* nios2-tdep.c (nios2_software_single_step): Adjust.
	* ppc-tdep.h (ppc_deal_with_atomic_sequence): Adjust.
	* rs6000-aix-tdep.c (rs6000_software_single_step): Adjust.
	* rs6000-tdep.c (ppc_deal_with_atomic_sequence): Adjust.
	* s390-linux-tdep.c (s390_software_single_step): Adjust.

	* tic6x-tdep.c (tic6x_software_single_step): Adjust.

gdb/gdbserver/ChangeLog:

	* linux-arm-low.c (arm_gdbserver_get_next_pcs): Adjust to
	software_single_step change of return type to
	std::vector<CORE_ADDR>.
	* linux-low.c (install_software_single_step_breakpoints):
	Likewise.
	* linux-low.h (install_software_single_step_breakpoints):
	Likewise.

Looks like a reasonable choice.  LGTM.

LGTM.

BTW, FYI, in general, {} initialization of vectors may not
always be a good idea.  See e.g.:

  https://akrzemi1.wordpress.com/2016/07/07/the-cost-of-stdinitializer_list/

C++17 will make it better (though not fully ideal).

But in this case CORE_ADDR is a scalar and it doesn't really
matter.

Other random "bare metal" / RTOSs that GDB doesn't need to know about
use solib-target too.  It's the default solib implementation exactly
to allow for GDB to remain agnostic about them.  That doesn't help
you with testing, it's just a FYI.

Note this was an XCNEW, which means that it zeroed all
memory.  Did you check whether all fields are initialized
after the patch?

As a general principle, I'd rather move all destruction bits to
the destructor at the same time when we C++fy a struct.
It doesn't really complicate the patch, while not doing it
makes it easier to leave these bits missed behind in a
random follow up patch that adds a dtor.

I.e., above, I'd prefer to move the xfree to a dtor in
the same patch.

It's in gdbarch.h because gdbarch.sh thinks it's part of the comment 
above short_bit, so it gets copied verbatim to the .h.  I don't know why 
it's there though.  It seems like it's been there for a really long 
time, but has always been commented out.  I had not seen it before doing 
this patch, and didn't worry too much about it.

Perhaps it was seen as a possible extension in case someone would bother 
adding support for targets with non-8-bit-bytes?  If so, the 
addressable_memory_unit_size method kind of took that place.

Any better guess?

Ouch, that's good to know.

 From what I understand, using {} to return an empty vector has no extra 
cost though, so we can use that without any problem.

New in v2:

 - lm_info pointer fields initialized in-class.
 - Added lm_info destructor.

Replace the two VEC fields with std::vector.

I found only one place where these lm_infos were allocated, but two
where they are freed.  It looks like solib_target_free_so missed freeing
section_bases before.

More c++ification is obviously possible, but my goal right now is to get
rid of VEC (CORE_ADDR).

gdb/ChangeLog:

	* solib-target.c (struct lm_info): Add default constructor,
	delete copy constructor and operator=.
	<segment_bases, section_bases>: Change type to
	std::vector<CORE_ADDR>.
	(library_list_start_segment, library_list_start_section,
	library_list_start_library, library_list_end_library,
	solib_target_free_library_list, solib_target_free_so,
	solib_target_relocate_section_addresses): Adjust.

Ah, it's commented out in gdbarch.sh.  I hadn't looked, and confused it
with the gdbarch hook you had added before.  But this is something much
older than that.

Yeah, that looks like it.

Guess we should just delete that commented out hook.

No.

Something else I realized is that these lm_info structures
are all defined differently in the different solib-*.c files.

It was OK in C, but in C++, that's an ODR violation
("-flto -Wodr" will tell you about them).

I think that as long as these types are PODs, it isn't a 
problem in practice, exactly due to C compatibility.
But as soon as we add non-trivial ctors/dtors (with external linkage),
then I think we're likely to run into problems as the linker picks
just one of the (different) types' ctor/dtor definitions assuming
they're all the same.

#1 - One way around it would be to make "struct lm_info" an
empty struct

  struct lm_info {};

in solist.h, instead of an opaque struct:

  struct lm_info;

and then make all lm_info implementations inherit from that
instead of redefining it.  You then need to add casts from
lm_info * to the appropriate type within each of the
solib-*.c implementations.

The downside is that this requires changing every port at the
same time, otherwise the solib-*.c files won't compile due to
lm_info redefinitions.

#2 - An alternative way, is to instead keep struct lm_info opaque,
and rename each solib-*.c lm_info's name.  E.g., do:

 -struct lm_info
 +struct solib_target_lm_info

And then add the casts between "solib_target_lm_info *"
and "lm_info *" in each solib-*.c as we convert them.
So you'd just do it in solib-target.c for now.  This is more
casts than the other approach (likely just one or two where
the lm_info object is constructed), because you now need to
cast in the solib_target_lm_info -> lm_info direction too.
However, if we changed so_list::lm_info to "void *" [1], we
would avoid those casts and only need the
lm_info -> solib_target_lm_info casts, as in the other approach.

[1] - the type is already opaque to common code so we'd not
really be adding any type hole at all.

#3 - Yet another approach is to get rid of the lm_info type and
replace it with inheriting the so_list type directly:

 struct solib_target_lib : so_list 
 {
    // old lm_info fields go here.
 };

This is I suspect, the cleanest.  It is already the responsibility
of the solib-*.c backend to create/destroy so_list objects.
It could also be done incrementally, I think.  We'd have to start by
touching all solib-*.c files to use new/delete instead of malloc/free
to allocate so_list objects, but after that, I think we could
progress one backend at a time as we find a need...

Thanks,
Pedro Alves

v3 simply updates the patch to the changes made to lm_info_target (previously
lm_info).

Replace the two VEC fields with std::vector.

gdb/ChangeLog:

	* solib-target.c (struct lm_info): Add default constructor,
	delete copy constructor and operator=.
	<segment_bases, section_bases>: Change type to
	std::vector<CORE_ADDR>.

Err I forgot to update the ChangeLog, here it is:

    gdb/ChangeLog:

            * solib-target.c: Include <vector>
            (struct lm_info_target) <~lm_info_target>: Remove.
            <segment_bases, section_bases>: Change type to

            library_list_end_library,
            solib_target_relocate_section_addresses): Adjust.

Is the ChangeLog format acceptable for the destructor?

I think this variable could be eliminated, and replaced by further
below doing:

 -		      low = section_bases[i];
 +		      low = li->section_bases[i];

in a couple places.

Otherwise LGTM.
