llvm-6502/test/CodeGen/PowerPC/ppc64le-aggregates.ll
Bill Schmidt a5ea0b50a4 [PowerPC] Complete setting the baseline for ppc64le 
Patch by Nemanja Ivanovic.

As was uncovered by the failing test case (when run on non-PPC
platforms), the feature set when compiling with -march=ppc64le was not
being picked up. This change ensures that if the -mcpu option is not
specified, the correct feature set is picked up regardless of whether
we are on PPC or not.

; Currently VSX support is disabled for this test because we generate lxsdx
; instead of lfd, and stxsdx instead of stfd. That is a poor choice when we
; have reg+imm addressing, and is on the list of things to be fixed.
; The second run step is to ensure that -march=ppc64le is adequate to select
; the same feature set as with -mcpu=pwr8 since that is the baseline for ppc64le.
