👾 Ah, the unbridled audacity of creating a "useful" x86-64 #ELF executable in a whole 301 bytes! Truly the pinnacle of modern computing—if your goal is to impress no one and achieve nothing. 🚀 Meanwhile, #GitHub continues its quest to overcomplicate everything with features that no one asked for. 😂

Considering how efficient Apple A*/M* CPUs are, do you think x86 is dead? Or it's just Apple's optimization that makes them work so efficient?
I'm using an Intel 12th gen and I hope ARM CPUs (or #RiscV 🙃 ) will be available for Linux in the next few years.

🚀🎉 #JSLinux now supports #x86_64, because running outdated operating systems in your #browser is exactly what everyone was asking for! 🤔👌 Experience the thrill of Alpine Linux and the #nostalgia of Windows 2000 in glorious console mode, because who needs modernity when you can have retro-tech headaches instead? 🤓🔧

Nova Lake is live on Godbolt. We are still early. I took the latest Clang/GCC trunk for a spin on Godbolt, and -march=novalake is officially here.

If the rumors hold true, we are looking at the single biggest architectural jump in Intel's history.

With the arrival of Intel APX, the x86-64 ISA is finally getting the modernization it deserves. Several notable things are:

- 16 new GPRs (%r16 - %r31).
- NDD (New Data Destination): 3-operand instructions help stop wasting cycles on mov to preserve src/dst registers.
- push2/pop2: Push and pop two registers at once.
- jmpabs: 64-bit jumps.
- NF Suppression: Math ops without touching %rflags.
- ccmp: Conditional comparisons, branchless code.

Additionally, with the AVX10 support, Intel will officially restore AVX-512 capabilities to its consumer lineup for the first time since Tiger Lake in 2020.

Both P-core and E-core will support AVX-512.

LLVM Bug: x86-64 inline assembly fails with "symbol is already defined" for local labels under optimization (-O1+)

When compiling x86-64 inline assembly that contains explicitly named local labels (e.g., `.Lcoro_resume_task_ret_addr`), Clang throws a "symbol is already defined" error if optimizations (-O1, -O2, -O3) are enabled. The exact same code compiles successfully at -O0 in Clang, and works perfectly across all optimization levels in GCC.
