    xtensa: abstract 'entry' and 'retw' in assembly code · d6d5f19e
    Max Filippov authored
    Provide abi_entry, abi_entry_default, abi_ret and abi_ret_default macros
    that allocate aligned stack frame in windowed and call0 ABIs.
    Provide XTENSA_SPILL_STACK_RESERVE macro that specifies required stack
    frame size when register spilling is involved.
    Replace all uses of 'entry' and 'retw' with the above macros.
    This makes most of the xtensa assembly code ready for XEA3 and call0 ABI.
