xorvoid commented on Linear scan register allocation on SSA bernsteinbear.com/blog/li... · Posted by u/surprisetalk
Oh man, block-argument-SSA makes so much more sense to me than Φ-SSA. That alone is going to change my life. Thank you, Max!
A lot of this process is the same as graph-coloring register allocation on SSA, of which I found an extensive explanation in Appel's textbook. I think it's maybe time for me to go back to it and do the exercises so I really understand it. The book unfortunately predates the linear allocator age.
The link to https://brrt-to-the-future.blogspot.com/2019/03/reverse-line..., which is a learner's introduction to the LuaJIT reverse linear scan allocator, also seems valuable.
Because block-argument is actually the “right way”. The phi-node is very un-natural.. in the same sort of way that pi should have been tau.
Also, notice the connection here between Phi nodes and Continuation Passing Style (CPS). It because obvious with the block-arg form because it’s just the same thing. Jumps to blocks are just calls that don’t return.

I FIREd and this is what I miss. Not a techie but a whitecollar job with a bunch of smart people. Miss that.
Same. But I guess I’ve just accepted it and moved on. I’m willing to give that up for not having to give up 75% of my wake hours to a purely economic entity.
I think I’m mostly surprised that so many smart/capable/successful people keep grinding long after they need to. And I’m sad that those of us that don’t have a harder time finding eachother because we don’t have a common career to put us in a room together constantly.
Ah well. Wouldn’t trade any of the great adventures I’ve had for a job or a large sum of money. I’m happy with my trade.

Uninstall the apps. Only use social media from a desktop. That gives you the physical separation in a sustainable way.
Agreed. I don’t use social media of any kind. Not even on the desktop. I always run with Downtime on. All new apps are disallowed from running or notifying unless I whitelist them explicitly.
You really don’t need this “attention porn” in your life. Just turn it all off. Make friends IRL instead. So worth it.

Is this still something that must be enabled at compile-time, or will it be supported via a runtime flag?
Compile time. There are preprocessor #if guards all over the code base to provide different implementations for core operations. Many of these are used to provide a thread-safe version (e.g. atomic refcount). Presumably, these should work fine single threaded (assuming correctness). But at the moment they are compile-time, yea.
" Even if one doesn’t accept every point made by Hobsbawm, Brenner, or similar Marxist thinkers, their analysis at least has a sturdy basis in political economy and material reality. By contrast, Thiel has a bizarrely cultural analysis of stagnation that doesn’t even pass the laugh test. The Western world, he claims, entered into five decades of anemic growth because of the counterculture of the 1960s. According to Thiel, “in my telling of the history of the 1970s…the hippies did win. We landed on the moon in July of 1969, Woodstock started three weeks later and, with the benefit of hindsight, that’s when progress stopped and the hippies won.” Thiel adds that “everyone became as deranged as Charles Manson.”
Because of the hippies, says Thiel, Western powers embraced an ideology of peace and safety that stalled technological growth."
