-/* RSEQ_SIG is a signature required before each abort handler code.
-
- It is a 32-bit value that maps to actual architecture code compiled
- into applications and libraries. It needs to be defined for each
- architecture. When choosing this value, it needs to be taken into
- account that generating invalid instructions may have ill effects on
- tools like objdump, and may also have impact on the CPU speculative
- execution efficiency in some cases.
-
- RSEQ_SIG uses the trap4 instruction. As Linux does not make use of the
- access-register mode nor the linkage stack this instruction will always
- cause a special-operation exception (the trap-enabled bit in the DUCT
- is and will stay 0). The instruction pattern is
- b2 ff 0f ff trap4 4095(%r0) */
