[llvm-commits] [PATCH] ARM: Custom lower v2f32 = fp_round to fix crash with NEON

[Pete Couperus]

Hello,

Lowering "fptrunc <2 x double> %a to <2 x float>" is broken on ARM with
NEON.
This patch custom lowers this conversion using two single element vcvt's.
This fixes the following PRs.

Please review!
Thanks.

Pete
