[PATCH] D22840: Split the store of an int value merged from a pair of smaller values into multiple stores.

[Wei Mi via llvm-commits]

wmi updated this revision to Diff 69450.
wmi added a comment.

Change the input of the target query to be elements of the value pair before they are merged. The target query only returns true on x86 when the input is a mixture of int and fp values.
Testcase update since now wide store of int value pair will not be splitted for now.
