[LLVMdev] Bounds checking

[Vikram S. Adve]

LLVM itself doesn't do any bounds checks, but if the language front  
end puts in any, they may be optimized (and hoisted) just as other  
comparison operators and branches might.  In other words, the LLVM  
passes don't recognize any bounds checks specifically.
