With this change, we'll be able to easily see how long does it take to compile LLVM vs rustc.

This is how the output currently looks like:

------------------------------------------------
Stage 1 (LLVM PGO):            1936.16s (21.44%)
  Build rustc and LLVM:        1447.07s (16.02%)
    LLVM:                       322.39s ( 3.57%)
    Rustc:                     1105.31s (12.24%)
  Gather profiles:              489.10s ( 5.41%)
Stage 2 (rustc PGO):           1579.59s (17.49%)
  Build rustc and LLVM:         650.87s ( 7.21%)
    LLVM:                       290.31s ( 3.21%)
    Rustc:                      342.16s ( 3.79%)
  Gather profiles:              928.72s (10.28%)
Stage 3 (LLVM BOLT):           2722.61s (30.14%)
  Build rustc and LLVM:        1892.67s (20.95%)
    LLVM:                      1141.65s (12.64%)
    Rustc:                      725.08s ( 8.03%)
  Gather profiles:              829.94s ( 9.19%)
Stage 4 (final build):         2794.01s (30.93%)
  LLVM:                         984.42s (10.90%)
  Rustc:                        414.21s ( 4.59%)
                                                
Total duration:                       2h 30m 32s
------------------------------------------------

Some notes:

  • As expected, the LLVM builds that are "context free" are cached well by sccache, but the ones that use profiles are much slower.
  • The final LLVM build, which uses PGO profiles, should be cached by sccache, because the profiles were already used in the BOLT build. This does not seem to be happening.
  • I wonder why the first rustc build is so much slower. I guess that the stage1 build is cached in later invocations?

Ok, now we have a nicely formatted output of the individual build steps duration in the log. There's no one single "bottleneck" in the dist build, it just takes time to build Clippy, Rust analyzer, Cargo, docs etc.

Added an assertion that at least one LLVM/rustc build step was found.
