Rules to avoid common extended inline assembly mistakes (nullprogram.com)
GCC and Clang inline assembly is an interface between high and low level programming languages. It is subtle and treacherous. Many are ensnared in its traps, usually unknowingly. As such, the asm keyword is essentially the unsafe keyword of C and C++. Nearly every inline assembly tutorial, including the awful ibilio page at the top of search engines for decades, propagate fundamental, serious mistakes, and most examples are incorrect. The dangerous part is that the examples usually produce the expected results!

GCC Preparing to Set C23 "GNU23" as Default C Language Version (phoronix.com)
The GNU Compiler Collection (GCC) support for the C23 programming language standard is now considered "essentially feature-complete" with GCC 15. As such they are preparing to enable the C23 language version (using the GNU23 dialect) by default for the C language version of GCC when not otherwise specified.

(Re)Using rustc components in gccrs (rust-gcc.github.io)
In order to speed up development, as well as make sure gccrs exposes the exact same behavior as rustc in critical compiler passes, we decided last year to start reusing components and crates from the official Rust compiler where possible.
