We now have Clang build profiling available, which generates Chrome
|
||
|
|
tracing files for each compilation unit. To enable it, run `meson configure
|
||
|
|
build -Dprofile-build=enabled` then rerun the compilation.
|
||
|
|
|
||
|
|
If you want to make the build go faster, do a clang build with meson, then run
|
||
|
|
`maintainers/buildtime_report.sh build`, then contemplate how to improve the
|
||
|
|
build time.

You can also look at individual object files' traces in
