Hi all,
This patch implements 64-bit immediate constant loads in NEON.
The current state is that you can load const_vector, but not const_int.
This is clearly not ideal. The result is a constant pool entry when it's
not necessary.
The patch disables the movdi_vfp patterns for loading DImode values, if
the operand is const_int and NEON is enabled, and extends the neon_mov
pattern to include DImode const_int, as well as the const_vector
operands. I've modified neon_valid_immediate only enough to accept
const_int input - the logic remains untouched.
That patch failed to bootstrap successfully, but this updated patch
bootstraps and tests with no regressions.
OK?
