The separated libcalls are implemented in terms of __divmodsi4 and __udivmodsi4 anyway, so we should always use them if possible. llvm-svn: 302462

; We run the tests with both the default optimization level and O0, to make sure
|
|
; we don't have any ABI differences between them. In principle, the ABI checks
|
|
; should be the same for both optimization levels (there could be exceptions
|
|
; from this when a div and a mod with the same operands are not coallesced into
|
|
; the same divmod, but luckily this doesn't occur in practice even at O0).
|
|
; Sometimes the checks that the correct registers are used after the libcalls
|
|
; are different between optimization levels, so we have to separate them.
