Reducing C++ Compilation Times Through Good Design - Andrew Pearcy - ACCU 2024

Will lld or mold improve build time with whole program optimizations enabled?

Excellent talk. Pretty much essential material for software at scale.

Anyone remember Turbo Pascal?
Remember how fast it was? Remember the hardware that it ran on?
Yeah. We've got a lot of catching up to do.
There is zero reason the executable can't be ready some milliseconds after a character has changed in the code.
That THE ENTIRE SOURCE is worked on, as if it has never been seen before, every time a build is started is comical.

Very good talk, thank you!

Restrict your use of header only libraries and templates in API boundaries, use PIMPL and forward declaration and you are fine.

The separation of protocol and implementation is really helpful. It makes testing much easier, too.
