Bug ID: 78303
Summary: PowerPC vec-init-{1,2,4,5,8,9} tests do not run on
-mlittle -maltivec=be
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: meissner at gcc dot gnu.org
Target Milestone: ---
I was fixing PR 78243, and I decided to try the vec-init-{1,2,4,5,8,9} tests
that I wrote when I was adding power8/power9 vector init/extract support with
the -maltivec=be option. None of the vec-init tests run with -maltivec=be.
This option says that even though we are running on a little endian target, the
ordering of elements within Altivec/VSX registers is still big endian to allow
code that was targeted towards the big endian PowerPC to run.
I tested both GCC 6 and the current GCC 7 sources, and both fail.
