Subject: [PATCH 1/2] Code cleanup: dwarf2_get_pc_bounds: -1/0/+1 -> enum
Make the code (maybe) more readable + primarily prepare it for [patch 2/2]
enum extension.
This change should have no code change impact.
gdb/ChangeLog
2016-05-30 Jan Kratochvil <jan.kratochvil@redhat.com>
Code cleanup: dwarf2_get_pc_bounds: -1/0/+1 -> enum
* dwarf2read.c (enum pc_bounds_kind) New.
(dwarf2_get_pc_bounds): Use it in the declaration.
(process_psymtab_comp_unit_reader): Adjust caller. Rename has_pc_info
to cu_bounds_kind.
(read_func_scope, read_lexical_block_scope, read_call_site_scope):
Adjust callers.
(dwarf2_get_pc_bounds): Use enum pc_bounds_kind in the definition.
(dwarf2_get_subprogram_pc_bounds, get_scope_pc_bounds): Adjust callers.

Where DW_TAG_lexical_block has no attributes. Such whole subtree is currently
dropped by GDB while I think it should just import all its children DIEs.
It even XFAIL->XPASSes gdb.ada/out_of_line_in_inlined.exp:

Subject: [PATCH 1/3] Never kill PID on: gdb exec PID
Hi,
in some cases with deleted main executable GDB will want to kill the inferior.
$ cp /bin/sleep /tmp/sleep;/tmp/sleep 1h&p=$!
$ rm /tmp/sleep
$ gdb /tmp/sleep $p
GNU gdb (GDB) 7.10.50.20151016-cvs
/tmp/sleep: No such file or directory.
Attaching to process 9694
/tmp/sleep (deleted): No such file or directory.
A program is being debugged already. Kill it? (y or n) _
The first attachment of "/tmp/sleep" commandline argument errors at:
#0 throw_error (error=GENERIC_ERROR, fmt=0x116d135 "%s.") at ./common/common-exceptions.c:371
#1 in throw_perror_with_name (errcode=GENERIC_ERROR, string=0x7fffffffdb96 "/dfsfds") at utils.c:974
#2 in perror_with_name (string=0x7fffffffdb96 "/dfsfds") at utils.c:982
#3 in exec_file_attach (filename=0x7fffffffdb96 "/dfsfds", from_tty=1) at exec.c:268
267 if (scratch_chan < 0)
268 perror_with_name (filename);
#4 in catch_command_errors_const (command=0x80f59f <exec_file_attach>, arg=0x7fffffffdb96 "/dfsfds", from_tty=1) at main.c:395
#5 in captured_main (data=0x7fffffffd6f0) at main.c:1051
1051 if (catch_command_errors_const (exec_file_attach, execarg,
1052 !batch_flag))
Then GDB tries to attach to the process $p:
#0 inferior_appeared (inf=0x240e0b0, pid=29210) at inferior.c:305
#1 in inf_ptrace_attach (ops=0x2339540, args=0x21dcdc0 "29210", from_tty=1) at inf-ptrace.c:206

1082 if (catch_command_errors (attach_command, pid_or_core_arg,
1083 !batch_flag) == 0)
This succeeds and since this moment GDB has a valid inferior. But despite that
the lines
1082 if (catch_command_errors (attach_command, pid_or_core_arg,
1083 !batch_flag) == 0)
still fail because consequently attach_command() fails to find the associated
executable file:

and therefore GDB executes the following:

Hi,
a038fa3e14a477d4d72a26c2e139fa47d2774be2 is the first bad commit
commit a038fa3e14a477d4d72a26c2e139fa47d2774be2
Author: Markus Metzger <markus.t.metzger@intel.com>
stack: check frame_unwind_caller_id
[PATCH v3 2/3] stack: check frame_unwind_caller_id
https://sourceware.org/ml/gdb-patches/2016-02/msg00363.html
Message-Id: <1455207283-12660-2-git-send-email-markus.t.metzger@intel.com>

-(gdb) PASS: gdb.dwarf2/dw2-undefined-ret-addr.exp: info frame
+(gdb) FAIL: gdb.dwarf2/dw2-undefined-ret-addr.exp: info frame
It happens on normal native Fedora 23 x86_64.
I am not completely sure about the reasons but it looks to me GDB behavior has
just changed.
OK for check-in?
Thanks,
Jan
