2018-03-20This PR shows that we get the load/store_lanes logic wrong for arm big-endian.Kyrylo Tkachov3-2/+35
It is tricky to get right. Aarch64 does it by adding the appropriate lane-swapping operations during expansion. I'd like to do the same on arm eventually, but we'd need to port and validate the VTBL-generating code and add it to all the right places and I'm not comfortable enough doing it for GCC 8, but I am keen in getting the wrong-code fixed. As I say in the PR, vectorisation on armeb is already severely restricted (we disable many patterns on BYTES_BIG_ENDIAN) and the load/store_lanes patterns really were not working properly at all, so disabling them is not a radical approach. The way to do that is to return false in ARRAY_MODE_SUPPORTED_P for BYTES_BIG_ENDIAN. Bootstrapped and tested on arm-none-linux-gnueabihf. Also tested on armeb-none-eabi. PR target/82518 * config/arm/arm.c (arm_array_mode_supported_p): Return false for BYTES_BIG_ENDIAN. * lib/target-supports.exp (check_effective_target_vect_load_lanes): Disable for armeb targets. * gcc.target/arm/pr82518.c: New test.

2018-03-20[ARM][PR82989] Fix unexpected use of NEON instructions for shiftsSudakshina Das4-7/+57
This patch fixes PR82989 so that we avoid NEON instructions when -mneon-for-64bits is not enabled. This is more of a short term fix for the real deeper problem of making an early decision of choosing or rejecting NEON instructions. There is now a new ticket PR84467 to deal with the longer term solution. (Please refer to the discussion in the bug report for more details).
