class SinkAndHoistLICMFlags

Declaration

class SinkAndHoistLICMFlags { /* full declaration omitted */ };

Description

Flags controlling how much is checked when sinking or hoisting instructions. The number of memory access in the loop (and whether there are too many) is determined in the constructors when using MemorySSA.
