RE: New patch: [AArch64] [BE] [1/2] Make large opaque integer modes endianness-safe.


Hi,

I think that's because Alan Hayward's original patch had a bug in it, which he
has fixed and should be submitting to gcc patches fairly soon. So it's probably
best waiting until he gets a new patch up I think.

Regards,
David.

I've applied both patches to recent trunk (r217483), and I still see
ICEs on aarch64_be, when running the advsimd-intrinsics/vldX.c tests.

I have them with Alan Hayward's patch alone, too. BTW, I thought that
patch had been approved by Marcus, but it's not in trunk yet. Maybe I
missed something.

Christophe.
