FW: Introducing the "wincall" Calling Convention for GCC

I present a novel calling convention named "wincall" designed specifically for GCC. This convention is accompanied by the [[__gnu__::__wincall__]] attribute and caters to the latest Intel APX instructions on Windows systems, excluding Linux, BSD, and similar platforms. Motivation: The current

79173 – add-with-carry and subtract-with-borrow support (x86_64 and others) (gnu.org) What I find quite interesting is things like this. Since llvm clang provides __builtin_addc __builtin_subc for all targets. Can we provide something

RE: PETITION TO REMOVE -fexec-charset in GCC. That is purely garbage and undefined behavior.

Glibc cannot deal with EBCDIC or any other charset besides UTF-8 since GCC itself does not emit exec-coding set to C library and C library just could not deal with it. Even glibc could deal with it, GCC allows different exec-charset to be linked with each other which is definitely an undefined

The locale shit is not thread safe. printf(“Hello World %d”,3) is undefined behavior under none-UTF-8 exec-charset. WTF WTF WTF. This is purely garbage tbh. Just remove this toggle. I want encoding, I can use another library. I do not need the compiler to do the shitty job for me to ruin my

Are you going to fix the addcarry_u64 and subborrow_u64 bugs in the future?
