; This testcase exposed a problem with a previous handling of selecting
|
||
|
|
; constant vectors (for vdelta). Originally a bitcast of a vsplat was
|
||
|
|
; created (both being ISD, not machine nodes). Selection of vsplat relies
|
||
|
|
; on its return type, and there was no way to get these nodes to be
|
||
|
|
; selected in the right order, without getting the main selection algorithm
|
||
|
|
; confused.
