Hi,
I'm interested in any information about implementations of switch instruction and its runtime cost. If it's very target dependent, I'm mostly care about X86. Pointing some LLVM code is also good.
grep -r "switch instruction" under directory llvm/lib shows a lot of stuff you
might have interest. Most of the code related to switch instructions are under
subdirectories IR and Transformation/Utils.
