This is why I was somewhat suprized to see the "isa" facilities included in LLVM without also disabling rtti. It will reduce the memory footprint a fair bit if you do disable it, at least based on my experience with other C++ projects. Evan Jones

Evan, In case it wasn't obvious from Misha's answer, the main reason for doing this is speed. RTTI is not very quick. Since LLVM is well contained, there are no IR classes that LLVM doesn't know about it. Using dynamic_cast is really only warranted when blending libraries together that have inheritance relationships between them that aren't known in one or more of the libraries.

Greetings, I'm trying to run The Bat! (email client by RITlabs) on Mac OS X 10.5.7 with the most current XQuartz installed. I compiled Wine 1.1.22 using MacPorts and confirmed it is working for simple Windows applications. (Btw, is this Wine or Darwine, since MacPorts seems to download and compile the official Wine sources?) After installing The Bat!, it starts up and immediately quits with

Hi: Is there any function in R which can convert the long/lat to UTM(Universal Transverse Mercator)? There are quite a few converters on Internet. However, the interface is designed as input->output which I can not convert lots of locations at the same time. Another question is whether there is a function in R which can tell the time zone from the location's lat/long? Thank you!

Why am i always getting this crash ?? I dont understand how can I make this work wine: Unhandled page fault on read access to 0x00000064 at address 0x7e72d7a6 (thread 0009), starting debugger...

I see a bunch of definitions scattered throughout LLVM, and I could not find good documentation on them. I don't understand why they exist when LLVM is being compiled with RTTI enabled. It seems to me that: isa<T>(x) is a substitute for (dynamic_cast<T>(x) != NULL) and there are some other similar casting tools defined in Casting.h. Why should I use these instead of C++'s
