I guess it is due to some design reason.

This patch adds new fields about bound violation into siginfo
structure. si_lower and si_upper are respectively lower bound
and upper bound when bound violation is caused.
These fields will be set in #BR exception handler by decoding
the user instruction and constructing the faulting pointer.

This patch adds new fields about bound violation into siginfo
structure. si_lower and si_upper are respectively lower bound
and upper bound when bound violation is caused.
These fields will be set in #BR exception handler by decoding
the user instruction and constructing the faulting pointer.
