Hello!
You may call me Ilvir. I got an issue while building U-Boot for MIPS
platform, because of __builtin_mips_cache needs optimization flags (like
-O2) while non-literal int passed in it ("int op" at example below).
Example code:
static inline void mips_cache(int op, const volatile void *addr)

Most likely this will be closed as fixed for GCC 12.
There are some riscv atomic issues which were fixed post GCC 13 too.
RISC-V suffers from extraneous sign extensions, despite/given the ABI
guarantee that 32-bit quantities are sign-extended into 64-bit registers,
meaning incoming SI function args need not be explicitly sign extended
(so do SI return values as most ALU insns implicitly sign-extend too.)

This patch fixes the handling of surrogate code points in all standard
facets for transcoding Unicode that are based on std::codecvt. Surrogate
code points should always be treated as error. On the other hand
surrogate code units can only appear in UTF-16 and only when they come
in a proper pair.
Tested x86_64-linux (GDB 13.2, Python 3.11). Pushed to trunk.

Some of these changes were suggested by autopep8's --aggressive
option, others are for readability.
Break long lines by splitting strings across multiple lines, or
introducing local variables to hold results.
Use raw

This copies the is_specialization_of function from printers.py (with
slight modification for versioned namespace handling) and reuses it in
xmethods.py to replace repetitive re.match calls in every class.
