As on other hosts, the CPU identification instruction is priveleged, so we need to look through /proc/cpuinfo. I copied the PowerPC way of handling "generic". Several tests were implicitly assuming z10 and so failed on z196. llvm-svn: 193742

; This file tests what happens when a displacement is converted from
|
|
; being relative to the start of a frame object to being relative to
|
|
; the frame itself. In some cases the test is only possible if two
|
|
; objects are allocated.
|
|
;
|
|
; Rather than rely on a particular order for those objects, the tests
|
|
; instead allocate two objects of the same size and apply the test to
|
|
; both of them. For consistency, all tests follow this model, even if
|
|
; one object would actually be enough.
|
|
|
|
; First check the highest in-range offset after conversion, which is 4092
|
|
; for word-addressing instructions like LDEB.
|

; emergency spill slots at 160(%r15), the amount that we need to allocate
|
|
; in order to put another object at offset 4088 is (4088 - 176) / 4 = 978
