surprised most dev gripes about bitcode is unpredictable optimization effects. Folks, we’ve been living in emulated ISAs since the 90s

@rentzsch I'm a lot less worried about emulated ISAs given that the chances I have to debug one are pretty much nil.

@landonfuller@rentzsch The idea of not running the same code everywhere is troubling. (Yes I realize that’s already not always happening.) - View other replies

@ameaijou@landonfuller@rentzsch often .NET apps are compiled to native on install, targeting the machine architecture -
@stuartcarnie@ameaijou@rentzsch The big difference is that CLR defines a high-level virtual machine, LLVM bitcode doesn't. -
@stuartcarnie@ameaijou@rentzsch Only time I've had to debug JVM's JIT was when working on HotSpot; same isn't true for unsafe languages. -
@landonfuller were you doing that because you were specifically working on the hotspot compiler? -
@stuartcarnie Yeah; mostly codegen fixes for the Mac OS X port. -
@landonfuller nice. Always been intrigued by runtime code-gen. LuaJIT is my current interest - what an impressive piece of work
