In 162c6aef1f ("gas: fold symbol table entries generated for
.startof.() / .sizeof.()") I screwed up quite badly, inverting the case
sensitive and case insensitive comparison functions.
read_a_source_file() would bump line numbers only when seeing a newline,
whereas is_end_of_line[] indicates further end-of-line characters, in
particular the nul character. s_linefile() attempts to compensate for
the bump, but was too aggressive with this so far: It should only adjust
when a newline ends the line. To facilitate such a check, the check for
nothing else on the line needs to move ahead, which luckily is easily
possible: The relevant two conditions match, and the function can
simply return from the body of that earlier instance of the conditional.
The more strict treatment in s_linefile() then requires an adjustment
to buffer_and_nest()'s invocation of the function: The line terminator
now needs to be a newline, not nul.
The buildbot pointed out that my value refactoring series introduced a
bug in ppc-linux-nat.c:
../../binutils-gdb/gdb/ppc-linux-nat.c: In member function ‘int ppc_linux_nat_target::num_memory_accesses(const std::vector<gdb::ref_ptr<value, value_ref_policy> >&)’:
../../binutils-gdb/gdb/ppc-linux-nat.c:2458:44: error: expected unqualified-id before ‘->’ token
2458 | if (VALUE_LVAL (v) == not_lval || v->->deprecated_modifiable () == 0)
I don't know how that happened, but I am checking in this patch which
I think should fix it. It just removes the second "->".
I can't readily test this, so perhaps there's another bug lurking
after this one.
Simon pointed out some spots were doing val.get()->mumble, where val
is a value_ref_ptr. These were introduced by the function-to-method
script, replacing older code that passed the result of .get() to a
function.
Now that value.h is using methods, we can instead rely on operator->.
This patch replaces all the newly-introduced instances of this.

This removes deprecated_lval_hack and the VALUE_LVAL macro, replacing
all uses with a call to value::lval.
Approved-By: Simon Marchi <simon.marchi@efficios.com>
This introduces the set_lval method on value, one step toward removing
deprecated_lval_hack. Ultimately I think the goal should be for some
of these set_* methods to be replaced with constructors; but I haven't
done this, as the series is already too long. Other 'deprecated'
methods can probably be handled the same way.

At the end of this series, I belatedly realized that values should
only be destroyed by value_decref. This patch marks the the
destructor private to enforce this.
Approved-By: Simon Marchi <simon.marchi@efficios.com>
This introduces a value::set_modifiable and changes a couple of spots
to use it.
I'm not completely sure the comments by deprecated_modifiable are
correct any more. Perhaps they should be removed and the method
renamed. Like so many before me, though, I've deferred investigation
of the issue.

This patch turns a grab bag of value functions to methods of value.
These are done together because their implementations are
interrelated.

This changes preserve_one_value to be a method of value. Much of this
patch was written by script.

This turns value_from_xmethod, result_type_of_xmethod, and
call_xmethod to be methods of value. value_from_xmethod is a static
"constructor" now.

A few functions in value.c were accessing the internal fields of
struct value. However, in these cases it seemed simpler to change
them to use the public API rather than convert them to be methods.
Approved-By: Simon Marchi <simon.marchi@efficios.com>
This turns many functions that are related to optimized-out or
availability-checking to be methods of value. The static function
value_entirely_covered_by_range_vector is also converted to be a
private method.

A coming patch will add value::copy, so this namespace-qualifies
existing calls to 'copy' in value.c, to ensure it will still compile
after that change is done.

This turns the remaining value_contents functions -- value_contents,
value_contents_all, value_contents_for_printing, and
value_contents_for_printing_const -- into methods of value. It also
converts the static functions require_not_optimized_out and
require_available to be private methods.

This turns the static function allocate_value_contents into a method
on value. It is temporarily public, until some users are converted.
set_limited_array_length is converted as well.
Approved-By: Simon Marchi <simon.marchi@efficios.com>
This changes value_fetch_lazy to be a method of value. A few helper
functions are converted as well, to avoid problems in later patches
when the data members are all made private.

This turns value_contents_raw, value_contents_writeable, and
value_contents_all_raw into methods on value. The remaining functions
will be changed later in the series; they were a bit trickier and so I
didn't include them in this patch.
Approved-By: Simon Marchi <simon.marchi@efficios.com>
This changes allocate_value_lazy to be a static "constructor" of
struct value.
I considered trying to change value to use ordinary new/delete, but it
seems to me that due to reference counting, we may someday want to
change these static constructors to return value_ref_ptr instead.
