That's true. I know profile-guided-optimization is used for Windows builds; unsure on other platforms. Actually, this sounds like a fairly interesting project

That's true. I know profile-guided-optimization is used for Windows builds; unsure on other platforms.
Actually, this sounds like a fairly interesting project to me: Given a tool chain and a source code base, can we prove this was a possible compilation? In the case of deterministic compilers this is trivial, but as you highlight, not all optimizers are.
- LukeShu 14y agoI'm fairly certain that PGO is used for all of the official binaries. I do know that Arch Linux's package (which is from source, not official binaries) is compiled with PGO, so the support is definitely there.
