[PATCH 1/2][GCC][Arm]: Fix MVE move from GPR -> GPR

2020-03-20 Thread Andre Vieira (lists)

Hi, This patch fixes the pattern mve_mov for the case where both MVE vectors are in R registers and the move does not get optimized away. I use the same approach as we do for NEON, where we use four register moves. Bootstrapped on arm-linux-gnueabihf and ran mve testsuite on arm-none-eabi.
