9c80ecd646 gdbserver: use std::list for all_threads
Remove the usage of inferior_list for the all_threads list in
gdbserver.  The entry field in thread_info is removed, and replaced by a
simple ptid field.

I added some functions to iterate (for_each_thread) and find threads
(find_thread).  However, changing all the users of find_inferior & co to
use these new functions would have made the patch way too big.  So I
opted instead to make find_inferior & co some shims, so that the
existing code only needs to be updated minimally.  We can then update
the existing code to use the new functions incrementally (I've started
to do the work, but I'll post it afterwards, see [1] if you want a peek).

This patch has been built-tested on all relevant platforms, except
lynx.  I also regtested using the native-gdbserver and
native-extended-gdbserver boards on x86.

9179355e65 gdbserver: Use std::list for all_processes
Remove the usage of inferior_list for the all_processes list in
gdbserver, replace it with an std::list. The entry field in process_info
is removed, and replaced by a simple pid field.

The pid_of macro, used for both processes and threads, is replaced with
separate functions.  For completeness, I changed ptid_of and lwpid_of to
functions as well.

c9cb8905b4 gdbserver: Use std::list for all_dlls
As a small step towards removing inferior_list/inferior_list_entry, this
patch replaces the usage of inferior_list for the list of dlls by an
std::list.  The dll_info type now uses an std::string for name and has a
simple constructor.

I am able to build gdbserver with mingw on Linux, but I am not able to
test this on a Windows machine (the only platform that uses this code).

2098b39391 Make to_traceframe_info return a unique_ptr
Since this target method returns an allocated object, return a
unique_ptr.  It allows getting rid a some cleanups here and there.

I had to shuffle the includes around.  First, target.h now needs to
include tracepoint.h, to get the definition of traceframe_info_up.
However, the definition of enum trace_find_type was later in target, so
I had to move it to tracepoint.h, so that the declaration of tfind_1
could know about it.  I then had to remove the include of target.h from
tracepoint.h, which caused a circular dependency (it was probably
included to get enum trace_find_type in the first place anyway).

Regression tested on the buildbot.

gdb/ChangeLog:

	* target.h: Include tracepoint.h.
	(enum trace_find_type): Move to tracepoint.h.
	(struct target_ops) <to_traceframe_info>: Return a unique ptr.
	* tracepoint.h: Don't include target.h
	(enum trace_find_type): Move from target.h.
	(parse_traceframe_info): Return a unique ptr.

4cdd21a8d3 Use std::vector for traceframe_info::memory
Straightforward change from a VEC to std::vector.  This allows making
the destruction of a traceframe_info trivial.

I added a constructor with parameters to mem_range to be able to
emplace_back directly with the values.  It is necessary to leave a
default constructor there because mem_range is still used in a VEC.

d0d292a274 Use std::vector for traceframe_info::tvars
Straightforward change to get rid of a VEC.  We need to new/delete
traceframe_info instead of malloc/free it.  I found three places that
allocate a traceframe_info (ctf_traceframe_info, tfile_traceframe_info
and parse_traceframe_info) and only one that frees it
(free_traceframe_info).

gdb/ChangeLog:

	* tracepoint.h (struct traceframe_info) <tvars>: Change type to
	std::vector<int>.
	* tracepoint.c (free_traceframe_info): Deallocate with delete.

b129dcac88 Use std::vector in linux_xfer_osdata_processgroups
This simplifies the code quite a bit, by removing the array of PID_T
that's actually an array of pairs of PID_T.

This code is only used to implement "info os procgroups".  I tested by hand
as well as by running gdb.base/info-os.exp for unix, native-gdbserver
and native-extended-gdbserver.

af5bf4ada4 Replace psymbol_allocation_list with std::vector
psymbol_allocation_list is basically a vector implementation.  We can
replace it with an std::vector, now that objfile has been C++-ified.

I sent this to the buildbot, there are a few suspicious failures, but
I don't think they are related to this patch.  For example on powerpc:

new FAIL: gdb.base/catch-syscall.exp: execve: syscall execve has returned
new FAIL: gdb.base/catch-syscall.exp: execve: continue to main
new FAIL: gdb.base/catch-syscall.exp: execve: continue until exit

I get the same failures when testing manually on gcc112, without this
patch.

3ec5942fbf ada: Use std::string in print_dynamic_range_bound
Replace this usage of GROW_VECT with an std::string.  I don't think
there's a reason for this variable to be static, other than it was
cumbersome to manage its lifetime (i.e. use a cleanup) before.

Tested by comparing the gdb.ada/*.exp test results before and after the
patch.

	* ada-typeprint.c (print_dynamic_range_bound): Use std::string.

300b6685f1 Skip a few tests on targets that can't use the "run" commmand.
These tests want to use raw "run", so skip them on targets that can't
do that.

Also adds a small utility procedure that clearly conveys intent instead of
explicitly checking use_gdb_stub in the testcases.

This makes sure these testcases continue to be skipped with
--target_board=native-gdbserver once that board stops setting
is_remote.

50500caf81 Fix gdb.base/testenv.exp against --target_board=native-extended-gdbserver
Currently we get:

  Running ..../src/gdb/testsuite/gdb.base/testenv.exp ...
  FAIL: gdb.base/testenv.exp: test no TEST_GDB var
  FAIL: gdb.base/testenv.exp: test with one TEST_GDB var

  FAIL: gdb.base/testenv.exp: test with TEST_GDB_GLOBAL
  FAIL: gdb.base/testenv.exp: test with TEST_GDB_GLOBAL unset

The problem is that the testcase relies on stdio.  While we could fix
this for gdbserver by read output from inferior_spawn_id, a better fix
it to not rely on stdio at all.  That's what this commit does.
Instead, it reads variables off of the inferior to extract the
necessary information.

Along the way, most of the .exp file is reimplemented/cleaned up using
more modern mechanisms.  E.g., with_test_prefix, proc_with_prefix,
save_vars, etc.  Also, a missing check for "is_remote host" is added.

If we make the native-gdbserver board be !is_remote, then the few

start running, and fail, with something like:

2399fe6ab0 Simplify tic6x and s390x expedite registers
Nowadays, we have six tic6x expedite registers, which are duplicated.

tic6x-c64xp-expedite = A15,PC
tic6x-c64x-expedite = A15,PC
tic6x-c62x-expedite = A15,PC
tic6x-c64xp-linux-expedite = A15,PC
tic6x-c64x-linux-expedite = A15,PC
tic6x-c62x-linux-expedite = A15,PC

in features/Makefile, we have

   echo "expedite:$(if $($*-expedite),$($*-expedite),$($(firstword $(subst -, ,$(notdir $*)))-expedite))" \
        >> $(outdir)/$*.tmp

which means for a given bar/foo-baz.xml, we'll look for either
bar/foo-baz-expedite or foo-expedite.  We can define only one generic
expedite register for all different ti6cx and s390x target descriptions.
Actually, we've done that for x86 target descriptions.

and they are not changed.

df479dc6e0 Tweak gdb.base/corefile.exp is_remote check
1. Otherwise, when we make native-gdbserver board no longer is_remote,
   we get:

  ERROR: gdbserver does not support attach 9327 without extended-remote

  "error "gdbserver does not support $command without extended-remote""

  That's fixed by using can_spawn_for_attach instead.

2. The gdb_protocol check fixes this current problem with
   --target_board=extended-remote-gdbserver:

FT32B is a new FT32 family member. It has a code
compression scheme, which requires the use of linker

f5ca00321d Eliminate is_remote check in gdb.base/scope.exp
This commit makes --target_board=native-gdbserver (and in principle
all other is_remote boards) pass all the same gdb.base/scope.exp tests
as native testing.

I first wrote the gdb.base/scope.exp change described in the ChangeLog
below and in the new comments in the patch, knowing that gdb_file_cmd
was the right thing to use here.

However, that revealed that the native-extended-gdbserver board should
be overriding gdb_file_cmd+gdb_reload instead of gdb_load, as is
hinted at by the comments on top of the default implementations in
testsuite/lib/gdb.exp, because otherwise a gdb_run_cmd after
gdb_file_cmd misses setting "set remote exec-file".  However, if we do
that and remove gdb_load, then we regress gdb.base/dbx.exp, so for now
keep the gdb_load override as well.

gdb/testsuite/ChangeLog:
2017-10-13  Pedro Alves  <palves@redhat.com>

	* gdb.base/scope.exp: Use build_executable + clean_restart +
