Excited to learn about how KDAB's Shivam Kunwar is tackling the challenge of mapping LLVM values to source-level expressions at #FOSDEM 2024. Discover how this project using #LLVM intrinsic functions can revolutionize code optimization and memory access Thank you, @fosdem! More info: https://fosdem.org/2024/schedule/event/fosdem-2024-1682-map-llvm-values-to-corresponding-source-level-expressions/ #CompilerOptimization #CodeOptimization #MemoryAccess

Did you know that for natural numbers:

{x: >= 0, y = 2ⁿ}

the follow holds true:

x mod y

is equal to

x & (y - 1)

Example:

31882511 mod 1024

is equal to

31882511 & 1023

(where `mod` is the modulo operation and `&` is bitwise-and)
