This series fixes a number of problems in the rs6000 backend, building
on top of https://gcc.gnu.org/ml/gcc-patches/2015-06/msg01396.html.
Patch 5,6,7 really need the fixed rtx_cost function to be applied
first, the others are independent of that change (if you're willing to
allow a failing testcase).
Bootstrapped and regression tested powerpc64le-linux and
powerpc64-linux.
Alan Modra (7):
[RS6000] Hide insns not needing to be public
[RS6000] Tidy rotates
[RS6000] rtx_costs for ROTATE/ASHIFT inside AND
[RS6000] rldic in rotate and mask patterns
[RS6000] Split mask64_2_operand rotates early
[RS6000] Cost multi-insn constants
[RS6000] Address cost
