gcc, Arm: Fix MVE move from GPR -> GPR
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.
gcc/ChangeLog:
2020-03-20 Andre Vieira <andre.simoesdiasvieira@arm.com>
* config/arm/mve.md (mve_mov<mode>): Fix R->R case.
gcc/testsuite/ChangeLog:
2020-03-20 Andre Vieira <andre.simoesdiasvieira@arm.com>
* gcc.target/arm/mve/intrinsics/mve_move_gpr_to_gpr.c: New test.
