H A D | static_inst.cc | 12510:b8203d3676fc Tue Dec 19 05:18:00 EST 2017 Giacomo Travaglini <giacomo.travaglini@arm.com> arch-arm: Don't change PSTATE in Illegal Exception return This patch fixes the Illegal Exception return handler. According to the armarm documentation, when PSTATE.IL is set to one because of an illegal exception return, PSTATE.{EL, nRW, SP} are unchanged. This means the Exception level, Execution state, and stack pointer selection do not change as a result of the return.
