Hi all,
The recently added gcc.target/arm/pr58041.c test exposed a bug in the backend.
When compiling for NEON and with -mno-unaligned-access we end up generating
the vld1.64 and vst1.64 instructions instead of doing the accesses one byte at
a time like -mno-unaligned-access expects. This patch fixes that by enabling
the NEON expander and insns that produce these instructions only when
unaligned accesses are allowed.
Bootstrapped on arm-linux-gnueabihf. Tested arm-none-eabi on qemu.
Ok for trunk and 4.8?
