// This test case tests the incremental compilation hash (ICH) implementation | ||
// for inline asm. | ||
|
||
// The general pattern followed here is: Change one thing between rev1 and rev2 | ||
// and make sure that the hash has changed, then change nothing between rev2 and | ||
// rev3 and make sure that the hash has not changed. | ||
|
||
// must-compile-successfully | ||
