...<some operations> The following code will also be correct, no matter what %other_cond is: %wider_cond = and i1 %cond, %other_cond call void (i1, ...) @llvm.experimental.guard(i1 %wider_cond) [ "deopt"() ] <do some useful stuff> More formally, if %cond_a implies %cond_b, it is always valid to replace guard(%cond_b) with guard(%cond_a). We use this fact to make some optimizations, for example Loop Predication and Guard Widening passes. Given this semantics, all optimizations may assume that at every point dominated by a guard its condition is true, as well as they...

Hi everyone, I have 3 types of people (for now): Staff Faculty Students To break them up into classes, but keep them in the same People table, I''ve broken them up like so (code and ''ends'' snipped): class Person < ActiveRecord::Base class Employee < Person class Staff < Employee class Faculty < Employee class Student < Employee So, when I insert
