This prevents us from needing a sv suffix, and potentially reduces the
need to run generic code for a single character (as contains,
starts_with, ends_with etc. for a char will be just a length and
equality check).
No functional changes.
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
This commit moves the length calculations out to be directly on the
StringView users. This is an important step towards the goal of removing
StringView(char const*), as it moves the responsibility of calculating
the size of the string to the user of the StringView (which will prevent
naive uses causing OOB access).
The `c_iflag` and `c_oflag` fields were swapped in the source code which
caused the bit values to be interpreted as the wrong flag. It was a
stupid mistake on my part.
This commit adds support for most of the useful POSIX-defined features.
This will come in handy when dealing with serial terminals that are
implemented in #7260.
Unfortunately, it isn't possible to use `Core::ArgsParser` due to the
oddity of the input format. Most of this code is therefore just data
wrangling and parsing.
