Hi, ARM and AArch64 will still vectorize bb-slp-34.c - we're not operating with a cost model so we vectorize to a 64-bit vector of two ints, and the permutes are just element swaps.
So, don't mark this test xfail for arm/aarch64. Checked on x86_64-none-linux-gnu, arm-none-eabi and aarch64-none-elf with no issues. OK? Thanks, James --- 2016-03-03 James Greenhalgh <james.greenha...@arm.com> * gcc.dg/vect/bb-slp-34.c: Don't XFAIL for ARM/AArch64.
