Consider test-case gdb.base/vla-optimized-out.exp, compiled using clang-10.

The relevant DWARF looks like this: the variable a:

<12c> DW_AT_name : a
<132> DW_AT_type : <0x189>

with the count attribute equated to the value of this artificial variable:

The location description of the variable is terminated with DW_OP_stack_value,
which according to the DWARF spec means that "the DWARF expression represents
the actual value of the object, rather than its location".
However, in attr_to_dynamic_prop, we set is_reference to true:
...
baton->locexpr.is_reference = true;
...
and use it in dwarf2_evaluate_property to dereference the value of the DWARF
expression, which causes the access to memory at address 0x6.
Fix this by ignoring the baton->locexpr.is_reference == true setting if
the expression evaluation has ctx.location == DWARF_VALUE_STACK, such that we
get:
...

gdb: improve command completion for 'print', 'x', and 'display'
A potential use of an uninitialised variable was introduced. This is
fixed in this commit.
Previously when analysing /FMT strings for tab completion we
considered two possibilities, either the user has typed '/', or the
user has typed '/' followed by an alpha-numeric character, as these
are the only valid FMT string characters.
This meant that if the user type, for example '/@' and then tried to
tab complete gdb would use an uninitialised variable.
Currently only the first character after the '/' is checked to see if
it is alpha-numeric, so if a user typed '/x@@' then gdb would be happy
to treat this as a FMT string.
Given the goal of this change was primarily to allow tab completion of
symbols later in the command when a /FMT was used then I decided to
just make the /FMT skipping less smart. Now any characters after the
'/' up to the first white space, will be treated as a FMT string.
gdb/ChangeLog:
* printcmd.c (skip_over_slash_fmt): Reorder code to ensure in_fmt

Now we have a way to tell libctf what the endianness of the symtab is,
get readelf to use it. (objdump doesn't need to do so, nor does ld,
because they both use BFD-aware mechanisms to open CTF dicts, so libctf
can automatically figure the symtab endianness out.)
binutils/ChangeLog
2020-11-23 Nick Alcock <nick.alcock@oracle.com>
* readelf.c (dump_section_as_ctf): Call ctf_arc_symsect_endianness.
The CTF symbol lookup machinery added recently has one deficit: it
assumes the symtab is in the machine's native endianness. This is
always true when the linker is writing out symtabs (because cross
linkers byteswap symbols only after libctf has been called on them), but
may be untrue in the cross case when the linker or another tool
(objdump, etc) is reading them.
Unfortunately the easy way to model this to the caller, as an endianness
field in the ctf_sect_t, is precluded because doing so would change the
size of the ctf_sect_t, which would be an ABI break. So, instead, allow
the endianness of the symtab to be set after open time, by calling one
of the two new API functions ctf_symsect_endianness (for ctf_dict_t's)
or ctf_arc_symsect_endianness (for entire ctf_archive_t's). libctf
calls these functions automatically for objects opened via any of the
BFD-aware mechanisms (ctf_bfdopen, ctf_bfdopen_ctfsect, ctf_fdopen,
ctf_open, or ctf_arc_open), but the various mechanisms that just take
raw ctf_sect_t's will assume the symtab is in native endianness and need
a later call to ctf_*symsect_endianness to adjust it if needed. (This
call is basically free if the endianness is actually native: it only
costs anything if the symtab endianness was previously guessed wrong,
and there is a symtab, and we are using it directly rather than using
symtab indexing.)
Obviously, calling ctf_lookup_by_symbol or ctf_symbol_next before the
symtab endianness is correctly set will probably give wrong answers --
but you can set it at any time as long as it is before then.

Note that, logically, this method should be "const". Unfortunately,
the implementation iterates on struct type objects starting with "this",
and thus trying to declare the method "const" triggers a compilation
error.
gdb/ChangeLog:
* gdbtypes.h (struct type) <fixed_point_type_base_type> New method,
replacing the fixed_point_type_base_type function. All callers
updated throughout this project.
(fixed_point_type_base_type): Remove declaration.
* gdbtypes.c (type::fixed_point_type_base_type): Replaces
fixed_point_type_base_type. Adjust implementation accordingly.
This is one step further towards the removal of all these macros.
gdb/ChangeLog:
* gdbtypes.h (struct type) <fixed_point_info, set_fixed_point_info>:
New methods.
(INIT_FIXED_POINT_SPECIFIC): Adjust.
(TYPE_FIXED_POINT_INFO): Delete macro.
(allocate_fixed_point_type_info): Change return type to void.
* gdbtypes.c (copy_type_recursive): Replace the use of
TYPE_FIXED_POINT_INFO by a call to the fixed_point_info method.
(fixed_point_scaling_factor): Likewise.
(allocate_fixed_point_type_info): Change return type to void.
Adjust implementation accordingly.
* dwarf2/read.c (finish_fixed_point_type): Replace the use of
TYPE_FIXED_POINT_INFO by a call to the fixed_point_info method.
This commit changes the interfaces of some of the methods declared
in gmp-utils to take a gdb::array_view of gdb_byte instead of a
(gdb_byte *, size) couple.
This makes these methods' API probably more C++-idiomatic.
* gmp-utils.h (gdb_mpz::read): Change buf and len parameters
into one single gdb::array_view parameter.
(gdb_mpz::write): Likewise.
(gdb_mpq::read_fixed_point, gdb_mpq::write_fixed_point): Likewise.
* gmp-utils.c (gdb_mpz::read): Change buf and len parameters
into one single gdb::array_view parameter.
Adjust implementation accordingly.
(gdb_mpz::write): Likewise.
(gdb_mpq::read_fixed_point, gdb_mpq::write_fixed_point): Likewise.
* unittests/gmp-utils-selftests.c: Adapt following changes above.
* valarith.c, valops.c, valprint.c, value.c: Likewise.
