>Compilation time

I remember part of the selling point of LLVM during its early stage was compilation time being so much faster than GCC.

LLVM started about 15 years after GCC. Considering LLVM is 23 years old already. I wonder if something new again will pop up.

A few months ago someone wrote a much faster -O0 backend for LLVM, though it seems it didn't get much attention upstream: https://discourse.llvm.org/t/tpde-llvm-10-20x-faster-llvm-o0...

There are also codegen projects that don't use LLVM IR that are faster like Cranelift: https://github.com/bytecodealliance/wasmtime/tree/main/crane...

LLVM is actually really really good at what it does (compiling c/c++ code). Not perfect, but good enough that it would take tens of thousands of competent man hours to match it
