LLVM does do bit pattern tracking. Referred to as value tracking or known bits analysis.

I’m not sure if the vectorizer uses it a ton, but isel does (though maybe not heavily for vector ops)


No, there is no credit risk, they print the money.


You can do this with non intrusive lists too. See c++’s merge/splice/etc. You can store the iterators in some other place as you do this, making it quite handy on occasion.


It’s strange, every startup offer either is obviously a horrible scam or comes from a place of fairness and is sold like a total scam.

I guess being honest brings about too many opportunities for people who don’t understand the finances to make (or be perceived to make ) promises they can’t keep. So you might as well just get into a race to present the most ridiculous stuff possible.


Pref shares do get diluted, they are however senior to common stock so they get money FIRST if there’s not enough to go around. There is some cap on this and sometimes it’s pretty high. Huge pref overhangs are, indeed, a problem.

Pref shares with a 1x preference are still worth like 10x common stock in early stage companies and it’s common for employed to get fucked by this.

Founders don’t get preferred shares (I think it’s really, really rare). There is founder pref stock, which is somewhat different. It’s common for founders to cash out some shares along the way, though.


Founders that take a pay cut from a high paying job should demand preferential shares to the value they are giving up.

If they were in job where they were saving $50k a year, then after becoming a founder they should be getting $50k worth of preferential shares per year because they are investing that much in the business.

Not that I've actually ever heard of founders getting preferential shares to match their dollars invested.


It would cost an extreme amount. The only reason to do something like that would be to defer capital gains into retirement while protecting your position.

You can use a collar for this at somewhat reasonable cost. Not sure how rolling that would compare to just using it to defer until you can cheaply sell and buy some fixed income ladder. Probably badly.

Also, there’s no capital gains to defer if you use a retirement account, which will be a better place for fixed income anyway.
