The main issue being fixed here is that APCS targets handling a "byval align N" parameter with N > 4 were miscounting what objects were where on the stack, leading to FrameLowering setting the frame pointer incorrectly and clobbering the stack. But byval handling had grown over many years, and had multiple layers of cruft trying to compensate for each other and calculate padding correctly. This only really needs to be done once, in the HandleByVal function. Elsewhere should just do what it's told by that call. I also stripped out unnecessary APCS/AAPCS distinctions (now that Clang emits byvals with the correct C ABI alignment), which simplified HandleByVal. rdar://20095672 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@231959 91177308-0d34-0410-b5e6-96231b3b80d8

; This test is fairly fragile. The goal is to ensure that "large" stack
|
|
; objects are allocated closest to the stack protector (i.e., farthest away
|
|
; from the Stack Pointer.) In standard SSP mode this means that large (>=
|
|
; ssp-buffer-size) arrays and structures containing such arrays are
|
|
; closet to the protector. With sspstrong and sspreq this means large
|
|
; arrays/structures-with-arrays are closest, followed by small (< ssp-buffer-size)
|
|
; arrays/structures-with-arrays, and then addr-taken variables.
|
|
;
|
|
; Ideally, we only want verify that the objects appear in the correct groups
|
|
; and that the groups have the correct relative stack offset. The ordering
|
|
; within a group is not relevant to this test. Unfortunately, there is not
|
|
; an elegant way to do this, so just match the offset for each object.
