A small number of tests incorrectly tried to pass -Wa,-g through to
GCC as an extra compile time flag, either to gdb_compile or
prepare_for_testing.
The problem is that the syntax used for passing the flags was
incorrect, and as a result these extra flags were being ignored.
Luckily, the 'debug' flag was being passed in each case anyway, which
means that the '-g' flag would already be added.
Given that all these tests pass 'debug', and the invalid flag has been
ignored for some time, I'm just removing the flags in this commit.
I've also changed the tests from using gdb_compile to
prepare_for_testing, which allows some extra code to be removed from a
couple of tests scripts.
There should be no change in the test results after this commit.

In the GDB test suite, there are still multiple invocations of
"target_info exists use_gdb_stub". However, the recommended way of
checking for use_gdb_stub is to call the convenience function of the same
name.
Replace these occurrences and just call "use_gdb_stub" instead.

This patch merges the masks for matching the stwux and stdux
instructions in rs6000-tdep.c:skip_prologue into a single mask that
only matches these two instructions.
Commit 72dd273062 fixed the warning described in PR tdep/18295, this
patch addresses the comment in the same PR indicating that the mask
was too permissive.
gdb/Changelog:
PR tdep/18295
* rs6000-tdep.c (skip_prologue): Match both stwux and stdux
a single mask.
|
|
This patch extends rs6000-tdep.c:skip_prologue so that it can detect
when the Link Register is saved using the frame pointer (usually r31)
in adition to the stack pointer (r1).
The frame pointer offset from the frame base is tracked separately
from the stack pointer offset for cases when the frame pointer is not
in synch with the stack pointer at the moment of the LR save.
Previously, "stq" could also be detected as an instruction that saves
LR or CR. Because this was likely unintentional, this patch also
restricts the matches to stw/stwu/std/stdu.
gdb/ChangeLog:
* rs6000-tdep.c (store_insn_p): New function.
(skip_prologue): New variable alloca_reg_offset. Set lr_reg
and cr_reg to their unshifted values. Use store_insn_p to
match LR saves using either R1 or fdata->alloca_reg. Use
store_insn_p to match CR saves. Set alloca_reg_offset
when alloca_reg and framep are set. Remove lr_reg shift
when assigning to fdata->lr_register.

Currently "info proc cmdline" on GNU/Linux does not show the full command
line, but only argument 0. And even a warning is shown if there are more.
This was discussed in 2014 already:
https://sourceware.org/ml/gdb-patches/2014-04/msg00212.html
Follow the advice there and avoid target_fileio_read_stralloc. Instead,
use target_fileio_read_alloc to read the whole command line and then
replace NUL characters by spaces. Also add an appropriate test case.
Note that gdbserver already handles this correctly.
gdb/ChangeLog:
* linux-tdep.c (linux_info_proc): For "info proc cmdline", print
command line args instead of emitting a warning.
gdb/testsuite/ChangeLog:
* gdb.base/info-proc.exp: Add test for "info proc cmdline".

The attribute is meaningful only in templates allowing embedded
broadcast. Drop them everywhere else.
|
|
A few of them were missed in commit 7ac2002247 ("x86: derive DispN
from BaseIndex") and also couldn't be removed by subsequent commits
touching certain templates anyway.
|
|
Since they're shorter to encode, the 0xa0...0xa3 encodings are preferred
for moves between accumulator and absolute address outside of 64-bit
mode. With HLE release semantics this encoding is unsupported though,
with the assembler raising an error. The operation is valid though, we
merely need to pick the longer encoding in that case.
|
|
The wrong placement of the Load attribute in the templates prevented
this from working. The disassembler also didn't handle this consistently
with other similar dual-encoding insns.
|
|
While many templates allowing multiple suitably matching XMM/YMM/ZMM
operand sizes can be folded, a few need to be split in order to not
wrongly accept "xmmword ptr" operands when only XMM registers are
permitted (and memory operands are more narrow). Add a test case
validating this.
|
|
Also add a new test case verifying that mixed operands of SIMD insns
with a size-less memory operand in the middle are properly rejected.

This patch replaces VEC(static_tracepoint_marker_p) with std::vector,
and does some c++ification around that. I thought a new overload of
hex2str was useful, so I added it as well as corresponding unit tests.
I also added an overload of ui_out::field_string that takes an
std::string directly.

tracepoint definitions
Since I modify the parse_static_tracepoint_marker_definition function in
the next patch, I wanted to write a unit test for it. Doing so showed
that it doesn't handle multiple consecutive static tracepoint
definitions separated by commas. However, the RSP documentation [1]
states that servers may return multiple definitions, like:
1234:6d61726b657231:6578747261207374756666,abba:6d61726b657232:
The problem is that the function uses strlen to compute the length of
the last field (the extra field). If there are additional definitions
in addition to the one we are currently parsing, the returned length
will include those definitions, and we'll try to hex-decode past the
extra field.
This patch changes parse_static_tracepoint_marker_definition to consider
the case where the current definition is followed by a comma and more
definitions. It also adds the unit test that found the issue in the
first place.
I don't think this causes any backwards compatibility issues, because
the previous code only handled single static tracepoint definitions, and
the new code handles that correctly.
gdb/ChangeLog:
* tracepoint.c (parse_static_tracepoint_marker_definition):
Consider case where the definition is followed by more
definitions.
* Makefile.in (SUBDIR_UNITTESTS_SRCS): Add
tracepoint-selftests.c.

The in-process agent does not handle tdescs with guarded storage yet.
This is fixed.

On S390, the guarded storage register set is only valid if guarded storage
is active. Reading/writing the register set yields errors if this is not
the case. Then gdbserver emits warnings like these:
Warning: ptrace(regsets_store_inferior_registers): No data available
Apart from confusing the user, this can also lead to test case failures
due to unexpected output. To suppress this, make the guarded storage
regsets read-only for now.
gdb/gdbserver/ChangeLog:
* linux-s390-low.c (s390_fill_gs): Remove function.
(s390_fill_gsbc): Remove function.
(s390_regsets): Set fill functions for the guarded storage regsets
to NULL.

On s390x, when running attach.exp with native-extended-gdbserver,
gdbserver crashes in find_regno like this:
.../regcache.c:252: A problem internal to GDBserver has been detected.
Unknown register tdb0 requested
On the GDB side it looks like this:
(gdb) attach 31568
Attaching to process 31568
Remote connection closed
The test case attempts to attach to a new process via the already running
gdbserver. Thus s390_arch_setup is called a second time, and that's where
the problem occurs. In order to determine the word width (32 or 64 bits),
s390_arch_setup reads the pswm register through the regcache. For that it
uses a temporary tdesc which is supposed to work for all s390 targets,
since the actual tdesc has not been determined yet. But in this second
round this doesn't work, because s390_regsets has been updated already and
now contains regsets not described by the temporary tdesc, such as the one
containing tdb0.
This is fixed by rearranging the logic in s390_arch_setup.
gdb/gdbserver/ChangeLog:
* linux-s390-low.c (s390_get_hwcap): Replace tdesc parameter by
the word size. Add comment.
(s390_get_wordsize): New function.
(s390_arch_setup): No longer select a temporary tdesc to fetch the
pswm with it. Instead, use s390_get_wordsize to determine the
word size first and derive the correct tdesc from that directly.

This patch addresses slowness when setting breakpoints, especially in
heavily templatized code. Profiling showed that find_pc_sect_line in
symtab.c was the performance bottleneck. The original logic performed a
linear search over ordered data. This patch uses a binary search, as
suggested by comments around the function. There are no behavioural
changes, but gdb is now faster at setting breakpoints in template code.
Tested using on make check on an x86 target. The optimisation speeds up
the included template-breakpoints.py performance test by a factor of 7
on my machine.

Complement commit 8988502d7534 ("MIPS/LD/testsuite: Correct dynamic
links with VR4100, VR4300 and VR5000") and commit bf48520113c4 ("gc.exp:
Fix a typo: $LFLAGS -> $LDFLAGS"), and remove extraneous additional LD
flags explicitly passed to the personality test on invocation. This
passing has accidentally leaked from a WIP version of the former change.
With the actual version committed the $LDFLAGS global variable is used
instead for `run_dump_test' to use implicitly, so that `-call_shared'
precedes `-lpersonality' on the linker's command line, as otherwise a
shared `libpersonality.so' library wouldn't be considered for linking,
causing the test to fail.

In Rust one can initialize a struct member from an identically-named
local variable by simply mentioning the member name in the
initializer, like:
let x = 0;
let y = Struct { x };
This initializes "Struct::x" from "x".
This patch adds this form of initializer to the Rust expression parser
and adds a test.

This converts observers from using a special source-generating script
to be plain C++. This version of the patch takes advantage of C++11
by using std::function and variadic templates; incorporates Pedro's
patches; and renames the header file to "observable.h" (this change
eliminates the need for a clean rebuild).
Note that Pedro's patches used a template lambda in tui-hooks.c, but
this failed to compile on some buildbot instances (presumably due to
differing C++ versions); I replaced this with an ordinary template
function.
Regression tested on the buildbot.

Some of GDB's trace test cases define a function end() and place a
breakpoint there with "break end". However, when libinproctrace is linked
to the binary, there are multiple methods named "end", such as
std::string::end() from the C++ library or format_pieces::end() from
common/format.h. GDB then creates multiple breakpoints instead of just a
single one, and some FAILs result, such as these:
FAIL: gdb.trace/trace-mt.exp: ftrace on: break end
FAIL: gdb.trace/trace-mt.exp: ftrace off: break end
Fix this by adding the "-qualified" option to the break commands. For
consistency, change all occurrences of "break end" (and similar) in all
trace test cases, even if the current behavior does not cause problems.
Also, consequently use the gdb_breakpoint convenience proc.

Many projects (e.g. the Linux kernel) and build systems use "silent"
rules, which means that they'll only print a summary of what's being
done instead of printing all the detailed command lines. While chatting
on the #gdb IRC channel, I realized a few people (including me) thought
it would be nice to have it in GDB too.
The idea is that too much text is not useful, the important information
gets lost. If there's only the essential information, it's more likely
to be useful. Most of the time, when I look at the build output, it's
to see how it's progressing. By just printing a brief summary of each
operation, I can easily spot what's currently being compiled and
therefore how the build progresses (with time you know the order in
which files are compiled almost by heart).
As with other projects (Linux, automake-based things, probably others),
it's possible to print the complete command lines by passing V=1 to make
(or any other non-zero value).
I had one hesitation about this: when people report build failures, we
are more likely to miss the full compile command line. We'll probably
sometimes need to ask people to include the build log with "make V=1".
I don't think it's a big downside, if other projects the size of the
Linux kernel can live with it, I'm sure we can too.

This removes make_cleanup_free_section_addr_info. Instead -- per
Simon's suggestion -- this changes section_addr_info to be a
std::vector.
Regression tested by the buildbot.
