gdb.base/break-idempotent.exp
Hi,
I see this fails below on arm linux native testing and remote testing
with "set remote hardware-watchpoint-limit 1",
rwatch global^M
There are not enough available hardware resources for this watchpoint.^M
(gdb) FAIL: gdb.base/break-idempotent.exp: always-inserted off: rwatch: twice: rwatch global
gdb.base/break-idempotent.exp sets two breakpoints/watchpoints on the
same address. GDB isn't smart enough calculate these two HW
watchpoints can fit in one HW debug register, so the error message
above isn't necessary (there is one HW watchpoint register on arm).
Because target_ops interface can_use_hardware_watchpoint doesn't
pass enough information to the target backend.
Note that if I don't "set remote hardware-watchpoint-limit 1" in
remote testing, this test passes without fails. However without
"set remote hardware-watchpoint-limit 1", many other watchpoint
tests fail.
This patch is to add a check to skip_hw_watchpoint_multi_tests
for rwatch and awatch. We can add such check for watch as well,
but GDB is able to switch to software watchpoint if HW resource
isn't available, it doesn't cause any fail, I decide not to skip.
gdb/testsuite:
2015-04-30 Yao Qi <yao.qi@linaro.org>
* gdb.base/break-idempotent.exp: If
skip_hw_watchpoint_multi_tests returns true, skip the tests

Note that the program stops in __syscall_pause, but its symbol is
stripped in glibc, so GDB doesn't know where the program stops.
__syscall_pause is a tail call in __libc_pause, so it returns to main
instead of __libc_pause. As a result, the backtrace is like,
#0 0x0000007fb7ebca88 in raise () from /lib/aarch64-linux-gnu/libc.so.6

#5 0x0000000000400664 in main () at ../../../binutils-gdb/gdb/testsuite/gdb.base/relativedebug.c:32
looks GDB does nothing wrong here. I looked back at the test case
gdb.base/relativedebug.exp, which was added
https://sourceware.org/ml/gdb-patches/2006-10/msg00305.html
This test was indented to test the problem that "backtraces no longer
display some libc functions" after separate debug info is installed.
IOW, it makes few sense to test against libc which doesn't have debug
info at all, such as my case.
This patch is to tweak the test case to catch the output of
"info shared", if "(*)" is found for libc.so, which means libc doesn't
have debug info, then skip the test.

2015-04-30 Yao Qi <yao.qi@linaro.org>
* gdb.base/relativedebug.exp: Invoke gdb command
"info sharedlibrary", and if libc.so doesn't have debug info,
skip the test.

Global entry stubs are used on ELFv2 to provide addresses for
functions not defined in a non-PIC executable but whose address is
taken, in much the same way as PLT stub code is used on other
targets to provide function addresses. We don't want to insert a
global entry stub just because (bogus) debug info refers to the
address of a non-local function, but we also don't want gold to die.

For no good reason the function tui_free_window() is freeing the locator
window when we pass it an SRC_WIN or a DISASSEM_WIN. This behavior
doesn't make much sense because the locator window is always visible and
its contents do not change when the main window changes.
This behavior triggers the above PR because when we switch from one TUI
window to another (in the PR, from the src window to the asm window) we
call tui_free_window() on the previously active window (in the PR, the
src window). The function then frees the src window along with the
locator window and later we segfault when the now-active asm window
tries to query the locator window about the inferior's PC.
This patch fixes this apparently wrong behavior by changing
tui_free_window() to not free the locator window when we pass it an
SRC_WIN or a DISASSEM_WIN.

FreeBSD kernels that support fork tracing always stop a process to
report events for exec. Such a process will have the PL_FLAG_EXEC
flag set in the pl_flags field of the ptrace_lwpinfo struct returned

exec, so use fbsd_pid_to_exec_file to query the pathname of the
process' executable.

Enable PT_FOLLOW_FORK on all processes. When this is enabled, both
the parent and child process stop when a fork or vfork occurs.
A target operation for wait uses PT_LWPINFO to fetch more detailed

sets the PL_FLAG_FORKED flag in the pl_flags field of the structure
returned by PT_LWPINFO as well as the pid of the new child process.
The child process sets the PL_FLAG_CHILD flag in the pl_flags field.
When a fork is detected, the wait hook waits for both processes to
report their respective events. It then reports the fork to GDB as
a single TARGET_WAITKIND_FORKED or TARGET_WAITKIND_VFORKED event.
The kernel does not guarantee the order the events are reported in.
If the parent process' event is reported first, then the wait hook
explicitly waits for the child process. If the child process' event
is reported first, the event is recorded on an internal list of
pending child events and the wait hook waits for another event.
Later when the parent process' event is reported, the parent will
use the previously-recorded child process event instead of explicitly
waiting on the child process.
To distinguish vfork events from fork events, the external process
structure for the child process is extracted from the kernel. The
P_PPWAIT flag is set in the ki_flags field of this structure if the
process was created via vfork, but it is not set for a regular fork.

Keep gold consistent with bfd erratum-fixing option names, so as to
ease life in Makefile/scripts.
gold/
* options.h (--fix-cortex-a53-843419): Rename option.
* aarch64.cc (AArch64_relobj::do_count_local_symbols): Use renamed
option.
(AArch64_relobj::scan_sections_for_stubs): Use renamed option.

When Output_section::is_input_address_mapped is called we have entries for
all dropped ranges, but not for all ranges.

* ppc-opc.c (DCBT_EO): New define.
(powerpc_opcodes) <lbarx>: Enable for POWER8 and later.
<lharx>: Likewise.
<stbcx.>: Likewise.
<sthcx.>: Likewise.
<waitrsv>: Do not enable for POWER7 and later.
<waitimpl>: Likewise.
<dcbt>: Default to the two operand form of the instruction for all
"old" cpus. For "new" cpus, use the operand ordering that matches
whether the cpu is server or embedded.
<dcbtst>: Likewise.
gas/testsuite/

ordering change.

This commit alters two places that manipulate object file filenames
to detect "target:" filenames and to not attempt to manipulate them
as paths on the local filesystem:
- allocate_objfile is updated to not attempt to expand "target:"
filenames with gdb_abspath.
- load_auto_scripts_for_objfile is updated to not attempt to load
auto-load scripts for object files with "target:" filenames.
gdb/ChangeLog:
* objfiles.c (allocate_objfile): Do not attempt to expand name
if name is a "target:" filename.
* auto-load.c (load_auto_scripts_for_objfile): Do not attempt
to load auto-load scripts for objfiles with "target:" filenames.

This patch does whatever was done in
https://sourceware.org/ml/gdb-patches/2015-04/msg00437.html to fix
broken gdb build for the AVR target.

gas/
* config/tc-aarch64.c (s_aarch64_inst): Don't align code for non-text
section.
(md_assemble): Likewise, move the align code outside the loop.

With the S390 vector ABI, vector registers are used for passing vector
arguments and for returning a vector. Support this ABI in inferior
function calls and when setting or retrieving a function's return
value.
gdb/ChangeLog:
* s390-linux-tdep.c: Include "elf/s390.h" and "elf-bfd.h".
(enum s390_vector_abi_kind): New enum.
(struct gdbarch_tdep)<vector_abi>: New field.
(s390_effective_inner_type): Add parameter min_size. Stop
unwrapping if the inner type is smaller than min_size.
(s390_function_arg_float): Adjust call to
s390_effective_inner_type.
(s390_function_arg_vector): New function.
(s390_function_arg_integer): Adjust comment.
(struct s390_arg_state)<vr>: New field.
(s390_handle_arg): Add parameter 'is_unnamed'. Pass vector
arguments according to vector ABI when appropriate.
(s390_push_dummy_call): Initialize the argument state's field
'vr'. Adjust calls to s390_handle_arg.
(s390_register_return_value): Handle vector return values.
(s390_return_value): Apply the "register" return value convention
to a vector when appropriate.
(s390_gdbarch_init): Initialize tdep->vector_abi.
* NEWS: Announce S390 vector ABI support.

Move related logic in the implementation of s390_return_value closer
together. This makes it easier to read and extend.
gdb/ChangeLog:
* s390-linux-tdep.c (s390_return_value_convention): Remove
function. Inline its logic...
(s390_return_value): ...here. Instead, move the handling of the
"register" return value convention...
(s390_register_return_value): ...here. New function.
