Tom Tromey a90ecff85a Remove cleanup from ppc-linux-nat.c
This removes a cleanup from ppc-linux-nat.c, by using
unique_xmalloc_ptr.  It also slightly simplifies the code by using
XDUP rather than XNEW and memcpy.

Pedro Alves 739b3f1d8f Make native gdbserver boards no longer be "remote" (in DejaGnu terms)
This commit finally clears the "isremote" flag in the native-gdbserver
and native-stdio-gdbserver boards.  The goal is to make all "native"
boards be considered not remote in DejaGnu terms, like the
native-extended-gdbserver board is too.

DejaGnu automatically considers boards remote if their names don't
match the local hostname.  That means that native-gdbserver and
native-extended-gdbserver are considered remote by default by DejaGnu,
even though they run locally.  native-extended-gdbserver, however,
overrides its isremote flag to force it to be not remote.  So we are
in that weird state where native-gdbserver is considered remote, and
native-extended-gdbserver is considered not remote.

A recent set of commits fixed all the problems (and some more) exposed
by testing with --target_board=native-gdbserver and
--target_board=native-stdio-gdbserver with isremote forced off on
x86-64 GNU/Linux.  I believe we're good to go now.

The native-stdio-gdbserver.exp/remote-stdio-gdbserver.exp boards
required deep non-obvious modifications unfortunately...  The problem
is that if a board is not remote, then DejaGnu doesn't call
${board}_spawn / ${board}_exec at all, and the
native-stdio-gdbserver.exp board relies on those procedures being
called.  To fix that, this commit redesigns how the stdio boards hook
into the testing framework to spawn gdbserver.  IMO, this is a good
change anyway, because the way its done currently is a bit of a hack,
and the result turns out to be simpler, even.  With this commit, they
now no longer load the "gdbserver" generic config, and hook at the
mi_gdb_target_load/gdb_reload level instead, making them more like
traditional board files.

To share code between native-stdio-gdbserver.exp and
remote-stdio-gdbserver.exp, a new shared stdio-gdbserver-base.exp file
is created.

Instead of having each native board clear isremote manually, boards
source the new "local-board.exp" file.

This also adds a new section to testsuite/README file discussing
local/remote/native, so that we can easily refer to it.

Simon Marchi a79b1bc6f6 Get rid of VEC(mem_range_s)
This patch replaces the last usages of VEC(mem_range_s) with
std::vector<mem_range>.  This allows getting rid of a few cleanups and
of the DEF_VEC_O(mem_range_s).

I added a test for normalize_mem_ranges to make sure I didn't break
anything there.

Regtested on the buildbot.

Pedro Alves 63f0e930d4 Work around GCC 6.3.1 bug

  https://sourceware.org/ml/gdb-patches/2017-09/msg00270.html
  https://sourceware.org/ml/gdb-patches/2017-10/msg00418.html

It manifests like this:

H.J. Lu 5c3261b0e8 ELF: Call check_relocs after opening all inputs
For all ELF targers, call check_relocs after opening all inputs and
garbage collection.  Since the symbol resolution is known, check_relocs
can be simplified.  Also garbage collection doesn't need to undo what
check_relocs has done for symbols which have been garbage collected.
Since ELF targets never see the removed sections, gc_sweep_hook can be
removed from elf_backend_data and we can avoid GOT/PLT with garbage
collection now.

Set link_info.check_relocs_after_open_input to TRUE for all linker
targets which use ELF linker and update garbage collection tests to
remove unused GOT section.

ldemul_after_check_relocs is added for powerpc to support --secure-plt,
--bss-plt and --sdata-got.

Tested natively without regressions on i686, x86-64 and x32.  Tested

Simon Marchi 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.

Simon Marchi 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.

Simon Marchi 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.

Simon Marchi 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.

gdb/ChangeLog:

	* memrange.h (struct mem_range): Add constructors.
	* tracepoint.h (struct traceframe_info) <memory>: Change type to
	std::vector<mem_range>.
	* tracepoint.c (free_traceframe_info): Don't manually free
	vector.

	(traceframe_available_memory): Likewise.

Simon Marchi 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.

Simon Marchi 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.

	* nat/linux-osdata.c: Include algorithm.
	(compare_processes): Remove.

Simon Marchi 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.

Simon Marchi 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.

GDB Administrator 867d918419 Automatic date update in version.in 2017-10-14 00:00:20 +00:00
Pedro Alves 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.

Pedro Alves 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 two TEST_GDB var
  FAIL: gdb.base/testenv.exp: test with one TEST_GDB var, after unset
  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.

Pedro Alves dad0c6d2f7 Don't run gdb.gdb/ selftests if use_gdb_stub is true
If we make the native-gdbserver board be !is_remote, then the few
tests that use the selftest-support.exp routines to debug gdb itself
start running, and fail, with something like:

  Running ..../src/gdb/testsuite/gdb.gdb/selftest.exp ...
  ERROR: tcl error sourcing ..../src/gdb/testsuite/gdb.gdb/selftest.exp.
  ERROR: gdbserver does not support run [....] without extended-remote

	  -re "Starting program.*Breakpoint \[0-9\]+,.*$function \\(\\).* at .*main.c:.*$gdb..."
      (procedure "selftest_setup" line 45)

This commit makes sure those tests continue to be skipped.

Pedro Alves 8b0553c18f Make gdb.base/find-unmapped.exp pass on remote targets

This commit makes the test pass there, and also enables in on

Yao Qi 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.

Re-run 'make GDB=/path/build/gdb all' to regenerate regformats/*.dat files,
and they are not changed.
