// This test verifies that IDIV bypass optimizations is used when compiling for

// Atom processors with O2. The optimization inserts a test followed by a
|
||||
// branch to bypass the slow IDIV instruction. This test verifies that global
|
||||
// context types are used when comparing with those in the BypassTypeMap.
