gcc/ChangeLog:
2017-09-27 Kelvin Nilsen <kelvin@gcc.gnu.org>
* config/rs6000/rs6000-p8swap.c (const_load_sequence_p): Revise
this function to return false if the definition used by the swap
instruction is artificial, or if the memory address from which the
constant value is loaded is not represented by a base address held
in a register or if the base address register is a frame or stack
pointer. Additionally, return false if the base address of the
loaded constant is a SYMBOL_REF but is not considered to be a
constant.
(replace_swapped_load_constant): New function.
(rs6000_analyze_swaps): Add a new pass to replace a swap of a
loaded constant vector with a load of a swapped constant vector.
