This commit is the result of the following actions:
- Running gdb/copyright.py to update all of the copyright headers to
include 2024,
- Manually updating a few files the copyright.py script told me to
update, these files had copyright headers embedded within the
file,
- Regenerating gdbsupport/Makefile.in to refresh it's copyright
date,
- Using grep to find other files that still mentioned 2023. If
these files were updated last year from 2022 to 2023 then I've
updated them this year to 2024.
I'm sure I've probably missed some dates. Feel free to fix them up as
you spot them.

/* byte_vector is a gdb_byte std::vector with a custom allocator that
|
|
unlike std::vector<gdb_byte> does not zero-initialize new elements
|
|
by default when the vector is created/resized. This is what you
|
|
usually want when working with byte buffers, since if you're
|
|
creating or growing a buffer you'll most surely want to fill it in
|
|
with data, in which case zero-initialization would be a
|
|
pessimization. For example:
|
|
|
|
gdb::byte_vector buf (some_large_size);
|
|
fill_with_data (buf.data (), buf.size ());
|
|
|
|
On the odd case you do need zero initialization, then you can still
|
|
call the overloads that specify an explicit value, like:
|
|
|
|
gdb::byte_vector buf (some_initial_size, 0);
|
|
buf.resize (a_bigger_size, 0);
|
|
|
|
(Or use std::vector<gdb_byte> instead.)
|
|
|
|
Note that unlike std::vector<gdb_byte>, function local
|
|
gdb::byte_vector objects constructed with an initial size like:
|
|
|
|
gdb::byte_vector buf (some_size);
|
|
fill_with_data (buf.data (), buf.size ());
|
|
|
|
usually compile down to the exact same as:
|
|
|
|
std::unique_ptr<byte[]> buf (new gdb_byte[some_size]);
|
|
fill_with_data (buf.get (), some_size);
|
|
|
|
with the former having the advantage of being a bit more readable,
|
|
and providing the whole std::vector API, if you end up needing it.
