-use-separate-modules , incremental compile? caching?

[xoxorwr]

Hi,

I was curious, according to the documentation for -use-separate-modules, it mentions:

The backend generates multiple build units which are then linked together

I first believed this was designed to compile modules incrementally (only the changes), but it doesn't; the objects always appear to be new.

My question is: will Odin support incremental builds? Or a type of caching?

I looked deeper and noticed: internal-cached, which appears to accomplish precisely what I envisioned.

My subsequent question was: is there any ongoing development for caching, or is that just old code from the past?

Odin appears to be an ideal candidate for incremental compilation.

Thank you.

Caching may be picked up again, but that's not why -use-separate-modules was added, but something that becomes possible as a result. The original impetus behind it is that LLVM has quadratic behavior that can be minimized by submitting each package as its own module.

internal-cached does not accomplish anything you envisioned. It's extremely dumb. It just checks to see if any file has changed, and if not, don't recompile. It's not meant to be used by anyone. It was just an idea I made in a day.
