For some reason I couldn't 'Reply' to compiler-guy's reply directly, so I'll try here. I'm familiar with the Chris Lattner article. Most of it (especially the second installment) shows bad outcomes from UB opt

Well-defined integer overflow would not preclude loop unrolling in this case. One simple alternative would be for the compiler to emit a guard, skipping unrolling in the case that (offset+16) overflows. This guard would be outside the unr

It isn't clear to me precisely what example you have in mind. If you are saying that deleting array bounds checks might have performance benefits that outweigh the security concerns, then I disagree. If you are saying that the compiler

I find it remarkable that about half of the 14 articles that I see linked on the Bloomberg home page "above the fold" (in my browser window) are cryptocurrency-related.

I've seen a real-world example something like this: int a[32] = {...}; int flag = 1 << index; if (index < ARRAYSIZE) { a[index] = x; return flag; } else { return 0; } The "1 <<

Even on modern processors, an ADD instruction does not corrupt memory. The C standard, in declaring that an integer overflow results in all-bets-are-off UB, is not enabling compilers to provide valuable optimizations.

Are you talking about the RAI that traded at $0.0186 a few days ago and that you can now sell for $0.00022 ? That's a "stablecoin"? https://atomars.com/trading/RAIUSDT

I think you have it backwards. Leverage is the ratio of your notional stake to your net equity. If you buy $200mm of Viacom with $100mm then you have $100mm of debt. When it goes up 2.5X, you now hold $500mm stock and still have debt of

Yeah, my comments about the author were mis-placed. This version redacts the source material in a way that comes across as nicer, although it retains the use of "n00b" to identify who is asking the question. I may have confused t
