Description

In this talk we will discuss clang-built kernel compile times, current
work to improve compiler performance and recommendations to reduce
build times regardless of toolchain.

We will present our findings alongside several metrics of compiler
performance, including:

  • Comparative timing breakdowns between toolchains
  • Linux perf profiling on clang builds of the kernel
  • Perfetto traces on clang builds of the kernel
I agree to abide by the anti-harassment policy I agree
