static RELOCO_UNSAFE_BUFFER_USAGE bool microfmt::arm_exidx_bytecode_decoder::execute_bytecode ( address_space_ref  space, uint32_t  unwind_word, uintptr_t &  io_sp, uintptr_t &  , register_context_ref  reg_ctx  )

inlinestaticnoexcept

Executes up to 3 inline unwind bytes from an exidx/extab word.

Parameters

space	Address space to read stack values from.
unwind_word	Descriptor word (personality + inline bytecode).
io_sp	In/out: virtual stack pointer.
io_pc	In/out: program counter.
reg_ctx	Target register context handle to write recovered registers into.

Returns

true when the bytecode was applied; false when a personality routine requires an external .ARM.extab table read.
