On ppc-lynx178, resuming the execution of a program after hitting
a breakpoint sometimes triggers a spurious SIG61 event:
(gdb) cont
Continuing.
Program received signal SIG61, Real-time event 61.
[Switching to Thread 39]
0x10002324 in a_test.task1 (<_task>=0x3ffff774) at a_test.adb:30
30 select -- Task 1
From this point on, continuing again lets the signal kill the program.
Using "signal 0" or configuring GDB to discard the signal does not
help either, as the program immediately reports the same signal again.
What happens is the following:
- GDB sends a single-step order to gdbserver: $vCont;s:31
This tells GDBserver to do a step using thread 0x31=49.
GDBserver does the step, and thread 49 receives the SIGTRAP
indicating that the step has finished.
- GDB then sends a "continue", but this time does not specify
which thread to continue: $vCont;c
GDBserver uses an arbitrary thread's ptid to resume the program's
execution (the current_inferior's ptid was chosen for that).
See lynx-low.c:lynx_resume:
if (ptid_equal (ptid, minus_one_ptid))
ptid = thread_to_gdb_id (current_inferior);
So far on all LynxOS platforms, this has been good enough. But
not so on LynxOS 178. If the ptid used to resume the execution
is not the same as the thread that did the step, we get the weird
signal.
This patch fixes the problem by saving the ptid of the thread
that last caused an event, received during a call to waitpid.
The ptid is saved in per-process private data.
gdb/gdbserver/ChangeLog:
* lynx-low.c (struct process_info_private): New type.
(lynx_add_process): New function.
(lynx_create_inferior, lynx_attach): Replace calls to
add_process by calls to lynx_add_process.
(lynx_resume): If PTID is null, then try using
current_process()->private->last_wait_event_ptid.
Add comments.
(lynx_clear_inferiors): Delete. The contents of that function
has been inlined in lynx_mourn;
(lynx_wait_1): Save the ptid in the process's private data.
(lynx_mourn): Free the process' private data. Replace call
to lynx_clear_inferiors by call to clear_inferiors.
Add -mcpu command to specify core type.
* doc/c-msp430.c: Update documentation.
* gas/msp430/opcodes.s: Use correct value for .arch pseudo.
* gas/msp430/msp430x.d: Use correct value for -mcpu option.
PT_DATA_ADDR and PT_TEXT_END_ADDR. Update comments.
(linux_read_offsets): Remove PT_TEXT_ADDR, PT_DATA_ADDR and
PT_TEXT_END_ADDR guards. Update comments.
(linux_target_op) <read_offsets>: Conditionally define to
linux_read_offsets if the target is UCLIBC and if it defines
PT_TEXT_ADDR, PT_DATA_ADDR and PT_TEXT_END_ADDR.
This results in an internal-warning when trying the completion
when in Ada mode:
(gdb) b simple<TAB>
/[...]/cleanups.c:265: internal-warning: restore_my_cleanups has found a stale cleanup
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
gdb/ChangeLog:
* ada-lang.c (ada_make_symbol_completion_list): Make sure
all cleanups are done before returning from this function.
gdb/testsuite/ChangeLog:
* gdb.ada/complete.exp: Add test verifying completion using
the "tab" key.

This patch adds simulator support for handling the armv7 instructions
'movw (immediate)' and 'movt'.
Compiler frequently use these instructions to load the 32bit addresses of
global variables, string pointers etc. into the general registers.
In absence of support of these instructions:
1. GDB run simulator fails to print even simple "hello world" string
on console.
2. Loading of global variable addresses into the registers fail causing
arithmetic operation failures.
Patch has been regression tested for arm-none-eabi (-march=armv7-a).
These forward declarations are a GNU extension, and they trigger
a build warning when the compiler does not support it.
gdb/ChangeLog:
* utils.h: #include "exceptions.h".
(enum errors): Remove partial declaration.
The current code attempts to provide relocation support when debugging
core files via the rs6000_xfer_partial method of the rs6000-nat
target_ops vector. However, this target_ops vector does not get pushed
on the target stack at all when debugging core files, thus bypassing
completely that part of the code.
This patch fixes the problem by extending corelow's core_xfer_partial
into handling the TARGET_OBJECT_LIBRARIES_AIX object.
gdb/ChangeLog:
* gdbarch.sh (core_xfer_shared_libraries_aix): New method.
* gdbarch.h, gdbarch.c: Regenerate.
* corelow.c (core_xfer_partial): Add TARGET_OBJECT_LIBRARIES_AIX
handling.
* rs6000-aix-tdep.h: New file.
* Makefile.in (HFILES_NO_SRCDIR): Add rs6000-aix-tdep.h.
* rs6000-aix-tdep.c: Include "rs6000-aix-tdep.h" and
"xml-utils.h".
(struct field_info, struct ld_info_desc): New types.
(ld_info32_desc, ld_info64_desc): New static constants.
(struct ld_info): New type.
(rs6000_aix_extract_ld_info): New function.
(rs6000_aix_shared_library_to_xml): Likewise.
(rs6000_aix_ld_info_to_xml): Likewise.
(rs6000_aix_core_xfer_shared_libraries_aix): Likewise.
(rs6000_aix_init_osabi): Add call to
set_gdbarch_core_xfer_shared_libraries_aix.
* rs6000-nat.c: Add "rs6000-aix-tdep.h" include.
Remove "xml-utils.h" include.
(LdInfo): Delete typedef.
(ARCH64_DECL, LDI_FIELD, LDI_NEXT, LDI_FD, LDI_FILENAME):
Delete macros.
(rs6000_ptrace_ldinfo): Change return type to gdb_byte *.
Adjust code accordingly.
(rs6000_core_ldinfo): Delete, folded into
rs6000_aix_core_xfer_shared_libraries_aix.
(rs6000_xfer_shared_library): Delete.
(rs6000_xfer_shared_libraries): Reimplement.
