Within the stack command there are a couple of places where fixed
strings are passed into functions that are really intended for
processing user input. These fixed strings are then processed and the
result returned.
Given that the input strings in these cases are fixed, and are always
"0", then the result will always be the same, the current frame. By
switching to using get_current_frame instead the code can be simplified,
and the intention of the code is clearer.
gdb/ChangeLog:

(parse_frame_specification_1): Rename to
parse_frame_specification.
(frame_info): Use parse_frame_specification.

The func command, available when starting gdb in dbx mode, is supposed
to take a function name and locate the frame for that function in the
stack. This has been broken for a while due to an invalid check of the
arguments within the worker function. Fixed in this commit.

string.

The 'frame' command is documented in two places. The 'select-frame'
command is only mentioned in one of these places.
Of the two places, having the description of 'frame' and 'select-frame'
in the section 'Selecting a Frame' seems like the most obvious choice,
which is where things like 'up' and 'down' are also documented.
This commit moves the documentation of 'frame' and 'select-frame' into
the 'Selecting a Frame' section, and removes the duplicate documentation
of the 'frame' command.
At the same time I have reordered the sections in the 'Examining the
Stack' chapter, moving the discussion of frame filters to the end of the
chapter; it feels odd that we talk about frame filters before such basic
things like navigating the stack, or examining stack frames in general.
gdb/doc/ChangeLog:
* gdb.texinfo (Frames): Remove 'frame' and 'select-frame'
description.
(Frame Filter Management): Move to later in the 'Examining the
Stack' chapter.
(Selection): Add entry for 'select-frame'.

This allows to avoid casting away the const qualification in
m32c_pseudo_register_write (which is the entry points for all other

Also, use gdb_byte* instead of void* to avoid casts when calling gdb

Nowadays, the instruction decodings and handling are mixed together
inside aarch64_relocate_instruction. The patch decouples instruction
decoding and instruction handling by using visitor pattern. That is,
aarch64_relocate_instruction decode instructions and visit each
instruction by different visitor methods. Each visitor defines the
concrete things to different instructions. Fast tracepoint instruction
relocation and displaced stepping can define their own visitors,
sub-class of struct aarch64_insn_data.

Assume foo_array is a pointer to a C structure. GDB must evaluate the
following expression properly, but it does not currently:
(gdb) print 1 && &foo_array[1].a
Attempt to take address of value not located in memory.
The problem is that in EVAL_AVOID_SIDE_EFFECTS mode,
eval.c:evaluate_subexp_standard always returns a not_lval value as the
result for a STRUCTOP_STRUCT operation. As a consequence, the rest of
the code believes that one cannot take the address of the returned
value.
This patch fixes STRUCTOP_STRUCT handling so that the VALUE_LVAL
attribute for the returned value is properly initialized. After this
change, the above session becomes:
(gdb) print 1 && &foo_array[1].a
$1 = 1
gdb/ChangeLog:
* eval.c (evaluate_subexp_standard) <STRUCTOP_STRUCT>: If
EVAL_AVOID_SIDE_EFFECTS mode, forward the VALUE_LVAL attribute
to the returned value.

This commit fixes a few issues in the mechanism for passing information
about ".org" and ".align" directives from the assembler to the linker,
used by the avr target.
In the original commit fdd410ac7a07dfb47dcb992201000582a280d8b2, there
were some mistakes when writing out information about ".align"
directives:
- An align with fill does not write out its information correctly, the
fill data overwrites the alignment data.
- Each alignment directive is recorded at the location where the
previous alignment directive should be recorded, the first alignment
directive is discarded.
In commit 137c83d69fad77677cc818593f9399caa777a0c5, the data produced by
objdump is not correct:
- It's miss-aligned due to a missing whitespace.
- The fill data for align with fill records is not displayed
correctly.
All of the above issues are addressed in this commit, and the test is
improved to cover these cases.

This patch fixes a buffer overflow in ada_unpack_from_contents
caused by one of the previous commits. This happens when trying
to print the value of an array of variant records.
The overflow happens while trying to print one element of the array.
Because the size of each element in the array is variable, the array
has a DWARF byte_stride attribute, which makes us treat the array
as if it was packed. And during the extraction of each array element,
we try to unpack an object using the array's byte stride as the size,
into an element whose size is actually less than the stride.
This patch fixes the issue by overriding the byte-stride with
the actual element's length.

There is some partial handling for dynamic types in
ada_value_primitive_packed_val, but this support was added
in a fairly ad hoc way, and actually only covered the situation
where OBJ is not NULL and its contents had not been fetched yet.
In addition, even in the cases that it does cover, it doesn't make
much sense. In particular, it was adjusting BIT_SIZE and SRC_LEN,
which are properties of the data to be extracted _from_, based
on TYPE's length once resolved, which is a property of the data
we want to extract _to_.
This patch hopefully adjust this function to handle dynamic types
correctly, and in all cases. It does so by unpacking the data into
a temporary buffer in order to use that buffer to resolve the type.
And _then_ creates the resulting value from that resolved type.

This patch is just preparation work which splits the function
ada_value_primitive_packed_val into two function: one which unpacks
the data, and the other which now uses it to implement

allow us to use the new function to unpack data without actually creating
a struct value as a result.

A number of local variables declared in ada_value_primitive_packed_val
have a name that could, IMO, be improved to, either: Be more explicit
about what the variable is about (Eg: "src" is an index, so rename it
to "src_idx"); or be more consistent with other variables that they
relate to: for instance, several variables refer to the source via
"src" (Eg: srcBitsLeft, nsrc), but the buffer they refer to is called
"bytes", so patch renames "bytes" to "src".
This should help read and understand a little more easily the code
inside this function. No real code change otherwise.

The vdso.exp test checks that we can access the VDSO memory when replaying.
Depending on the line information generated by the compiler, runto_main may run
to the line marked with bp.1 or stop before that line. The test incorrectly
assumes that it will always run to the marked line and fails if it doesn't.
The test does not really care about what is traced. It does care that GDB is
replaying when capturing the second disassemble output.
Reflect that in the test by ignoring the output of the stepping and record goto
begin commands and by checking that GDB is actually replaying.
testsuite/
* gdb.btrace/vdso.c (main): Remove breakpoint markers.
* gdb.btrace/vdso.exp: Change stepping command to "next" and ignore
its output. Ignore the output of "record goto begin" and instead
check that GDB is replaying.

This patch fixes this racy failure, with the native-extended-gdbserver
board:

Note that the output is correct; it's just that inferior output
appeared after gdb's output, and the test doesn't handle that
correctly.
This comment isn't really correct, unfortunately:
# waiting. If we had already seen the status wrapper exit,
# gdb_test_multiple/expect has no spawn ids left, and thus
# returns.
That's true of expect in general, but I had missed / forgot that
gdb_test_multiple internally has extra matches using "-i
$gdb_spawn_id", so even if the caller clears all the indirect spawn id
lists, gdb_test_multiple will continue waiting.
So do a conditional exp_continue manually instead.
