gdb/arm: avoid undefined behavior shift when decoding immediate value
When loading the code file provided in PR 26828 and GDB is build with
UBSan, we get:

/home/simark/src/binutils-gdb/gdb/arm-tdep.c:1551:30: runtime error: shift exponent 32 is too large for 32-bit type 'unsigned int'
The sequence of instructions at pthread_cond_wait, in the
libpthread.so.0 library, contains this instruction with an immediate
constant with a "rotate amount" of 0:
e24dd044 sub sp, sp, #68 ; 0x44
Since arm_analyze_prologue shifts by "32 - rotate amount", it does a 32
bit shift of a 32 bit type, which is caught by UBSan.
Fix it by factoring out the decoding of immediates in a new function,
arm_expand_immediate.
I added a selftest for arm_analyze_prologue that replicates the
instruction sequence. Without the fix, it crashes GDB if it is build
with --enable-ubsan.
I initially wanted to re-use the abstract_memory_reader class already in
arm-tdep.c, used to make arm_process_record testable. However,
arm_process_record and arm_analyze_prologue don't use the same kind of
memory reading functions. arm_process_record uses a function that
returns an error status on failure while arm_analyze_prologue uses one
that throws an exception. Since i didn't want to introduce any other
behavior change, I decided to just introduce a separate interface
(arm_instruction_reader). It is derived from
abstract_instruction_reader in aarch64-tdep.c.

gdb: rewrite how per language primitive types are managed
Consider the following GDB session:
$ gdb
(gdb) set language c
(gdb) ptype void
type = void
(gdb) set language fortran
(gdb) ptype void
No symbol table is loaded. Use the "file" command.
(gdb)
With no symbol file loaded GDB and the language set to C GDB knows
about the type void, while when the language is set to Fortran GDB
doesn't know about the void, why is that?
In f-lang.c, f_language::language_arch_info, we do have this line:
lai->primitive_type_vector [f_primitive_type_void]
= builtin->builtin_void;
where we add the void type to the list of primitive types that GDB
should always know about, so what's going wrong?
It turns out that the primitive types are stored in a C style array,
indexed by an enum, so Fortran uses `enum f_primitive_types'. The
array is allocated and populated in each languages language_arch_info
member function. The array is allocated with an extra entry at the
end which is left as a NULL value, and this indicates the end of the
array of types.
Unfortunately for Fortran, a type is not assigned for each element in
the enum. As a result the final populated array has gaps in it, gaps
which are initialised to NULL, and so every time we iterate over the
list (for Fortran) we stop early, and never reach the void type.
This has been the case since 2007 when this functionality was added to
GDB in commit
cad351d11d6c3f6487cd.
Obviously I could just fix Fortran by ensuring that either the enum is
trimmed, or we create types for the missing types. However, I think a
better approach would be to move to C++ data structures and removed
the fixed enum indexing into the array approach.
After this commit the primitive types are pushed into a vector, and
GDB just iterates over the vector in the obvious way when it needs to
hunt for a type. After this commit all the currently defined
primitive types can be found when the language is set to Fortran, for
example:
$ gdb
(gdb) set language fortran
(gdb) ptype void
type = void
(gdb)
A new test checks this functionality.
I didn't see any other languages with similar issues, but I could have
missed something.

arc: Write correct "eret" value during register collection
In collect_register() function of arc-linux-tdep.c, the "eret"

This patch fixes that.
Background:
When asked for the "pc" value, we have to update the "eret" register
with GDB's STOP_PC. The "eret" instructs the kernel code where to
jump back when an instruction has stopped due to a breakpoint. This
is how collect_register() was doing so:

regnum = ARC_ERET_REGNUM;
regcache->raw_collect (regnum, buf + arc_linux_core_reg_offsets[regnum]);

Root cause:
Although this is using the correct offset (ERET register's), it is also
changing the REGNUM itself. Therefore, raw_collect (regnum, ...) is
not reading from "pc" anymore.

gdb: add an option flag to 'maint print c-tdesc'
GDB has two approaches to generating the target descriptions found in
gdb/features/, the whole description approach, where the XML file
contains a complete target description which is then used to generate
a single C file that builds that target description. Or, the split
feature approach, where the XML files contain a single target feature,
each feature results in a single C file to create that one feature,
and then a manually written C file is used to build a complete target
description from individual features.
There's a Makefile, gdb/features/Makefile, which is responsible for
managing the regeneration of the C files from the XML files.
However, some of the logic that selects between the whole description
approach, or the split feature approach, is actually hard-coded into
GDB, inside target-descriptions.c:maint_print_c_tdesc_cmd we check the
path to the incoming XML file and use this to choose which type of C
file we should generate.
This commit removes this hard coding from GDB, and makes the Makefile
entirely responsible for choosing the approach. This makes sense as
the Makefile already has the XML files partitioned based on which
approach they should use.
In order to allow this change the 'maint print c-tdesc' command is
given a new command option '-single-feature', which tells GDB which
type of C file should be created. The makefile now supplies this flag
to GDB.
This did reveal a bug in features/Makefile, the rx.xml file was in the
wrong list, this didn't matter previously as the actual choice of
which approach to use was done in GDB. Now the Makefile decides, so
placing each XML file in the correct list is critical.
Tested this by doing 'make GDB=/path/to/gdb clean-cfiles cfiles' to
regenerate all the C files from their XML source. There are no
changes after this commit.

gdb/testsuite: add "breakpoint always-inserted" axis in gdb.base/continue-after-aborted-step-over.exp
The test gdb.base/continue-after-aborted-step-over.exp fails on ROCm GDB
[1] when using the unix board (when debugging a standard x86-64/Linux
program), with:
(gdb) b *0^M
Breakpoint 2 at 0x0^M
Warning:^M
Cannot insert breakpoint 2.^M
Cannot access memory at address 0x0^M
^M
(gdb) FAIL: gdb.base/continue-after-aborted-step-over.exp: displaced-stepping=off: b *0
This happens because that build of GDB defaults to "set breakpoint
always-inserted on", for reasons that are unrelevant to explain here.
As soon as the breakpoint is created, GDB tries to insert it and
(expectedly) fails. This causes more text to be output than what the
pattern expects.
It is actually be relevant to run the test with both "set breakpoint
always-inserted" on and off. With it on, it mimics what happens when
running in non-stop mode, with other threads running. This is relevant
for upstream even outside of the ROCm port, so here's a patch for it.
Add this other axis and adjust the "b *0" test to handle the extra
output when it is on.

RISC-V: Update ABI to the elf_flags after parsing elf attributes.
Originally, if the -mabi option isn't set, then assembler will set the
abi according to the architecture string in the riscv_after_parse_args.
But we should also check and reset the abi later since the architecture
string may be reset by the elf attributes. Therefore, set the abi to
the elf_flags in the riscv_after_parse_args seems too early. Besides,
we have to set the abi_xlen before assembling any instruction, so it
should be safe to call riscv_set_abi_by_arch at the place that we set
start_assemble to TRUE. However, one minor case is that we won't call
the md_assemble when we are assembling an file without any instruction.
It seems that we still need to set the abi in riscv_elf_final_processing,
to make sure that abi can be updated according to the elf arch attributes.
For the rv32i and most elf toolchains, this patch can fix the mis-matched
ABI errors for Run pr26391-5 and Run pr26391-6 testcases. Besides, it
also correct the elf header flags of the output objects. Consider the
new testcases, mabi-fail-02 and mabi-noabi-attr-[01|02|03], they are
failed before applying this patch.
But I still get the mis-matched ABI errors for the following toolchains
when runnung the riscv-gnu-toolchain regressions,
newlib-rv32imafc-ilp32f-[medlow|medany]
linux-rv32imac-ilp32-[medlow|medany]
linux-rv32imafdc-ilp32-[medlow|medany}
linux-rv64imac-lp64-[medlow|medany]
linux-rv64imafdc-lp64-[medlow|medany}
For the newlib-rv32imafc-ilp32f, although we try to choose the abi
according to the elf attributes, we will use FLOAT_ABI_SOFT rather
than the FLOAT_ABI_SINGLE for the assmebly file wihtout setting the
-mabi, but compiler will set the abi to FLOAT_ABI_SINGLE for the
C files.
As for the linux toolchains, we also get fails for Run pr26391-5 and
Run pr26391-6 testcases. Since the linux toolchain won't generate elf
attributes to correct the ISA, and the --with-arch configure option
isn't set, assembler will try to set the default arch to rv[32|64]g,
which means the FLOAT_ABI_DOUBLE will be choosed, and may be conflict
with the abi set by the toolchain.
Therefore, I would suggest that it's is more safe to set the --with-arch
when building binutils, but it may break some testcases. For example,
ld-scripts/fill and ld-scripts/empty-address-2 may be broken when c-ext
is set. We might insert R_RISCV_ALIGN to make sure the 4-byte alignment,
but the dump result will be a bit different from what the testcase expected.
However, this patch only fix the problem - the abi, elf_flags and the
instruction, which is generated according to the abi_xlen, are all fixed
once the elf attributes are set for most elf toolchains. Other mis-matched
ABI problems should be fixed when we always build the binutils with the
--with-arch= configure option.

Dump of expression @ 0x4eced60, after conversion to prefix form:
Expression: `call_me (&main::val, VAL(Aborted (core dumped)
The situation was even worse for Fortran function calls, or array
indexes, which both make use of the same expression opcode.
The problem was that in a couple of places the index into the
expression array was handled incorrectly causing GDB to interpret
elements incorrectly. These issues are fixed in this commit.
There are already some tests to check GDB when 'set debug expression
1' is set, these can be found in gdb.*/debug-expr.exp. Unfortunately
the cases above were not covered.
In this commit I have cleaned up all of the debug-expr.exp files a
little, there was a helper function that had clearly been copied into
each file, this is now moved into lib/gdb.exp.

gdb/testsuite: make DWARF assembler's ranges' "base" and "range" procs
When creating a .debug_ranges section using the testsuite's DWARF
assembler, it currently looks like this:
ranges {
sequence {
{base ...}
{range ...}
{range ...}

The sub-tree of sequence is manually traversed as a list of lists. I
think it would be nicer if `base` and `range` where procedure, just like
the other levels:
ranges {
sequence {
base ...
range ...
range ...
}
}
That makes the implementation more robust, and the usage a bit nicer
(less special characters). It also allows having comments in between
the range list entries:
ranges {
sequence {
base ...
range ...
# Hello world.
range ...
}
}

Split macro_buffer in two classes, fix Clang build
GDB currently fails to build with (at least) Clang 10 and 11, due to:
$ make
CXX macroexp.o
../../src/gdb/macroexp.c:125:3: error: definition of implicit copy constructor for 'macro_buffer' is deprecated because it has a user-declared destructor [-Werror,-Wdeprecated-copy-dtor]
~macro_buffer ()
^
Now, we could just add the copy constructor, like we already have a
copy assignment operator. And like that assignment operator, we would
assert that only shared buffers can be copied from.
However, it is hard to see why only shared buffers need to be copied.
I mean, it must be true, otherwise macro support would be broken,
since currently GDB is relying on the default implementation of the
copy constructor, which just copies the fields, which can't work
correctly for the non-shared version. Still, it's not easy to tell
from the code that that is indeed correct, that there isn't some
corner case that would require copying a non-shared buffer.
Or to put it simply - the tangling of shared and non-shared buffers in
the same macro_buffer struct makes this structure hard to understand.
My reaction was -- try splitting the macro_buffer class into two
classes, one for non-shared buffers, and another for shared buffers.
Comments and asserts like these:
...
SRC must be a shared buffer; DEST must not be one. */
static void
scan (struct macro_buffer *dest,
struct macro_buffer *src,
struct macro_name_list *no_loop,
const macro_scope &scope)
{
gdb_assert (src->shared);
gdb_assert (! dest->shared);
... made me suspect it should be possible. Then after the split it
should be easier to reimplement either of the classes if we want.
So I decided to try splitting the struct in two distinct types, and
see where that leads. It turns out that there is really no good
reason for a single struct, no code that wants to work with either
shared or non-shared buffers. It's always shared for input being
parsed, and non-shared for output.
This commit is the result. I named the new classes
shared_macro_buffer and growable_macro_buffer.
A future direction could be for example to make shared_macro_buffer
wrap a string_view and growable_macro_buffer a std::string. With that
in mind, other than text/len, only the 'last_token' field is common to
both classes. I didn't feel like creating a base class just for that
single field.
I constified shared_macro_buffer's 'text' field, which of course had
some knock-on effects, fixed in the patch.
On the original warning issued by Clang -- now it is clear that only
the shared version needs to be copied. Since this class doesn't need
a user-declared destructor, the default implementations of the copy
assign/ctor can be used, and Clang no longer warns.
The growable version doesn't need to be copied, so I disabled
copy/assign for it.

This patch:
+ updates RAS feature system registers with new RAS 1.1 regs.
+ extends RAS/RAS 1.1 support for all architecture levels of Armv8-A.
Please note that early Armv8-A architectures do not officially support RAS
extension.
Rationale of the patch:
To ease development so that user-friendly RAS system registers operands can be
used. Certain use cases require developers to enable only more generic
architecture (e.g. -march=armv8-a) during system development. Users must use
RAS extension registers bearing in mind that system they use must support it.
The RAS (Reliability, Availability, Serviceability) extension is a
system-level extension that defines a number of system registers.
RAS 1.1 (FEAT_RASv1p1) introduces five new system registers:
ERXPFGCTL_EL1, ERXPFGCDN_EL1, ERXMISC2_EL1, ERXMISC3_EL1 and

Synthesize array descriptors with -fgnat-encodings=minimal
When -fgnat-encodings=minimal, the compiler will avoid the special
GNAT-specific "encodings" format, and instead emit ordinary DWARF as
much as possible.
When emitting DWARF for thick pointers to arrays, the compiler emits
something like:
<1><11db>: Abbrev Number: 7 (DW_TAG_array_type)
<11dc> DW_AT_name : (indirect string, offset: 0x1bb8): string
<11e0> DW_AT_data_location: 2 byte block: 97 6
(DW_OP_push_object_address; DW_OP_deref)
<11e3> DW_AT_type : <0x1173>
<11e7> DW_AT_sibling : <0x1201>
<2><11eb>: Abbrev Number: 8 (DW_TAG_subrange_type)
<11ec> DW_AT_type : <0x1206>
<11f0> DW_AT_lower_bound : 6 byte block: 97 23 8 6 94 4
(DW_OP_push_object_address; DW_OP_plus_uconst: 8; DW_OP_deref;
DW_OP_deref_size: 4)
<11f7> DW_AT_upper_bound : 8 byte block: 97 23 8 6 23 4 94 4
(DW_OP_push_object_address; DW_OP_plus_uconst: 8; DW_OP_deref;
DW_OP_plus_uconst: 4; DW_OP_deref_size: 4)
If you read between the lines, the "array" is actually a structure
with two elements. One element is a pointer to the array data, and
the other structure describes the bounds of the array. However, the
compiler doesn't emit this explicitly, but instead hides it behind
these location expressions.
gdb can print such objects, but currently there is no way to construct
one. So, this patch adds some code to the DWARF reader to recognize
this construct, and then synthesize an array descriptor. This
descriptor is then handled by the existing Ada code.
Internally, we've modified GCC to emit the structure type explicitly
(we will of course be sending this upstream). In this case, the array
still has the DW_AT_data_location, though. This patch also modifies
gdb to ignore the data location in this case -- this is preferred
because the location only serves to confuse the Ada code that already
knows where to find the data. In the future I hope to move some of
this handling to the gdb core, so that Ada-specific hacks are not
needed; however I have not yet done this.
Because parallel types are not emitted with -fgnat-encodings=minimal,
some changes to the Ada code were also required.
The change ina ada-valprint.c was needed to avoid infinite recursion
when trying to print a constrained packed array. And, there didn't
seem to be any need for a recursive call here -- the value could
simply be returned instead.
Finally, gdb.ada/frame_arg_lang.exp no longer works in C mode, because
we drop back to the structure approach now. As mentioned earlier,
future work should probably fix this again; meanwhile, this doesn't
seem to be a big problem, because it is what is currently done (users
as a rule don't use -fgnat-encodings=minimal -- which is what I am
ultimately trying to fix).
Note that a couple of tests have an added KFAIL. Some
-fgnat-encodings=minimal changes have landed in GNAT, and you need
something very recent to pass all the tests. I'm using git gcc to
accomplish this.

However, at the end of the .debug_abbrev section in dw2-line-number-zero-dw.S,
we have four ".byte 0" entries:
...
.uleb128 0x12 /* DW_AT_high_pc */
.uleb128 0x01 /* DW_FORM_addr */
.byte 0x0 /* Terminator */
.byte 0x0 /* Terminator */
.byte 0x0 /* Terminator */
.byte 0x0 /* Terminator */
...
The first two are the attribute list terminator, the third is the end-of-table
terminator, and the last is superfluous/incorrect.
Fix this by emitting instead:
...
.uleb128 0x12 /* DW_AT_high_pc */
.uleb128 0x01 /* DW_FORM_addr */
.byte 0x0 /* DW_AT - Terminator */
.byte 0x0 /* DW_FORM - Terminator */
.byte 0x0 /* Abbrev end - Terminator */
...
where the last comment resembles the comment for other abbreviation codes:
...
.section .debug_abbrev
.Labbrev1_begin:
.uleb128 2 /* Abbrev start */
...

gold: ensure file_counts_lock is initialized before using
Since upgrading to binutils 2.35 I've been experiencing random memory
corruption related crashes with ld.gold --threads. It's caused by
multiple threads concurrently pushing elements onto the shared
std::vector in File_read::record_file_read(). This vector is supposed to
be protected by file_counts_lock, but that is initialized lazily and
might be NULL when File_read::open() is called, in which case
Hold_optional_lock silently skips locking it.
Fix by calling the initialize() method before attempting to acquire the
lock, the same as other places that use file_counts_lock.

gdb, gdbserver, gdbsupport: fix leading space vs tabs issues
Many spots incorrectly use only spaces for indentation (for example,
there are a lot of spots in ada-lang.c). I've always found it awkward
when I needed to edit one of these spots: do I keep the original wrong
indentation, or do I fix it? What if the lines around it are also
wrong, do I fix them too? I probably don't want to fix them in the same
patch, to avoid adding noise to my patch.
So I propose to fix as much as possible once and for all (hopefully).
One typical counter argument for this is that it makes code archeology
more difficult, because git-blame will show this commit as the last
change for these lines. My counter counter argument is: when
git-blaming, you often need to do "blame the file at the parent commit"
anyway, to go past some other refactor that touched the line you are
interested in, but is not the change you are looking for. So you
already need a somewhat efficient way to do this.
Using some interactive tool, rather than plain git-blame, makes this
trivial. For example, I use "tig blame <file>", where going back past
the commit that changed the currently selected line is one keystroke.
It looks like Magit in Emacs does it too (though I've never used it).
Web viewers of Github and Gitlab do it too. My point is that it won't
really make archeology more difficult.
The other typical counter argument is that it will cause conflicts with
existing patches. That's true... but it's a one time cost, and those
are not conflicts that are difficult to resolve. I have also tried "git
rebase --ignore-whitespace", it seems to work well. Although that will
re-introduce the faulty indentation, so one needs to take care of fixing
the indentation in the patch after that (which is easy).
