Description
Summary of changes
This is a small but important extra job for the simplify-cfg pass. It replaces any
jmpifterminator instructions withjmps if the condition is a known constant. This takes place before the inlining block into its predecessor check, so if removing one of the block's successors causes that optimization to apply, the if construct will be completely flattened into one block.Dependency additions / changes
