; This test case tests the InstructionCombining optimization that
|
|
; reduces things like:
|
|
; %Y = cast sbyte %X to uint
|
|
; %C = setlt uint %Y, 1024
|
|
; to
|
|
; %C = bool true
|
|
; It includes test cases for different constant values, signedness of the
|
|
; cast operands, and types of setCC operators. In all cases, the cast should
|
|
; be eliminated. In many cases the setCC is also eliminated based on the
|
|
; constant value and the range of the casted value.
