Max Filippov July 8, 2020, 10:20 p.m. UTC
DFPU may be configured with 32-bit or with 64-bit registers. Xtensa ISA
does not specify how single-precision values are stored in 64-bit
registers. Existing implementations store them in the low half of the
registers.
Add value extraction and write back to single-precision opcodes.
Add new double precision opcodes. Add 64-bit register file.
Add 64-bit values dumping to the xtensa_cpu_dump_state.
