LLVM at Igalia
- One of the nice parts of #llvm is that often times you'll find yourself needing to do some sort of non-trivial analysis, but usually there's already a pass for it. Here's how you can reuse a block frequency analysis to make a chess engine 7% faster on #riscv: lukelau.me/2026/01/26/c...
- Does LLVM produce slower RISC-V code than GCC? Currently, yes. Can we make LLVM produce faster code? Also, yes! lukelau.me/2025/12/10/c... #llvm #riscv

- Trying to find the slowest possible RISC-V instruction. This single vlse8.v with a stride of 65536 bytes takes 66 million cycles on a Banana Pi F3. That's 0.04 seconds @1.6GHz #risc-v
