; Stack reload folding tests - we use the 'big vectors' pattern to guarantee spilling to stack.
|
|
;
|
|
; Many of these tests are primarily to check memory folding with specific instructions. Using a basic
|
|
; load/cvt/store pattern to test for this would mean that it wouldn't be the memory folding code thats
|
|
; being tested - the load-execute version of the instruction from the tables would be matched instead.
