@BRIAN_____ @rustlang @SwiftLang That also applies to Rust's bounds checking. LLVM getting better at optimizing leaves Rust further behind.

@BRIAN_____@rustlang@SwiftLang i.e. if it gets better at merging cases, Rust's exceptions are causing more and more missed optimizations.2 replies 0 retweets 0 likes -

@CopperheadSec@rustlang@SwiftLang The Rust team is considering adding a compiler switch to make panics abort instead of unwind...1 reply 0 retweets 0 likes -

@CopperheadSec@rustlang@SwiftLang ...In theory, with that switch, the compiler could optimize more fully like Swift. But...1 reply 0 retweets 0 likes -

@CopperheadSec@rustlang ...it seems unlikely that significant optimizations would be made just for that non-default mode.2 replies 0 retweets 0 likes -
Replying to @BRIAN_____
@BRIAN_____@CopperheadSec@rustlang I doubt we would ignore significant optimizations because we have an unwinding mode.2 replies 0 retweets 0 likes -

@rustlang@wycats@CopperheadSec Good to hear. If I understand the RFC correctly, though, it requires substituting a custom libstd?1 reply 0 retweets 0 likes -

@BRIAN_____@rustlang getting full benefit requires a std with special flags, but work on better cross-compilation makes this easy.1 reply 0 retweets 1 like
@huon_w @BRIAN_____ @rustlang in other words, we make progress incrementally :) slow and steady wins the race.
