Great read. Did @rustlang people know about @swiftlang's overflow checking optimizations? A topic worth revisiting.https://twitter.com/johnregehr/status/718199181295362049 …
@CopperheadSec @rustlang @SwiftLang The Rust team is considering adding a compiler switch to make panics abort instead of unwind...

-
@CopperheadSec@rustlang@SwiftLang ...In theory, with that switch, the compiler could optimize more fully like Swift. But... -
@CopperheadSec@rustlang ...it seems unlikely that significant optimizations would be made just for that non-default mode. -
@BRIAN_____@CopperheadSec@rustlang I doubt we would ignore significant optimizations because we have an unwinding mode. -
@wycats@CopperheadSec@rustlang Good to hear. Looking forward to seeing the improvements. -
@BRIAN_____@wycats@CopperheadSec it just so happens that https://twitter.com/rustlang/status/718545850226589696 … just happened! -
@rustlang@wycats@CopperheadSec Good to hear. If I understand the RFC correctly, though, it requires substituting a custom libstd? -
@BRIAN_____@rustlang getting full benefit requires a std with special flags, but work on better cross-compilation makes this easy. -
@huon_w@BRIAN_____@rustlang in other words, we make progress incrementally :) slow and steady wins the race.
