Does fil-c have a way of disabling the capability model for regions of code? (Rust's `unsafe` blocks come to mind). Maybe if I ask enough stupid questions, you'll get pissed and get the kernel to build/work with fil-c just to

Just as the sanitizers have a runtime, the linux kernel has a re-implementation of those runtimes (the linux kernel does not link libgcc/compiler_rt) and IIRC the compiler will work differently (I forget which flags control that). Prio

If you do get around to adding the flag, consider a suggestion for the color of bikeshed: `-fyolo`. (Can't find my April Fool's clang patch for adding `-feverything`; hard to search the phab archive)

Or perhaps a `--target` flag that says "I'm targeting the linux kernel, not userspace, libcall these symbols (existing kernel functionality) rather than those (glibc interfaces)."

Does fil-clang have `-fno-` flag to control disabling fil-c stuff? Does the fil-c runtime depend on specifics from glibc, or is it that LFS doesn't support building with musl? > We need to retain the Yolo GCC for compiling the Linux

Dunno, just upgraded Fedora to Fedora 43 and all of the games I had set up (wine) stopped working. Will try gaming on Linux again next decade.

I wish we standardized on Do Not Track headers. Cookie banners are a plague. Thanks Europe.

This is a false dichotomy, from someone who profits from such manufactured fear.

You'd think that, but in effect kconfig/kbuild has many cases where they say "if the compiler supports flag X, use it" where X implies an ABI break. Per task stack protectors comes to mind.
