special cases, such as the kernel's gate DSO, it will be

(compile_reg): Set val directly to register number, instead of unw.preg_index[i].
Use IA64_INSN_INC_PSP instead of IA64_INSN_ADD to pop a fixed stack frame.
(build_script): Handle signal-frames by directly copying abi_marker, rather than
emitting an IA64_INSN_SET instruction.

a save-location. Only exceptions are IA64_INSN_INC_PSP and
IA64_INSN_LOAD_PSP.
