Modified files:
sys/ia64/ia64 trap.c
Log:
When speculation fails (as determined by the chk instruction) the
processor is to jump to recovery code. This branching behaviour
may not be implemented by the processor and a Speculative Operation
fault is raised. The OS is responsible to emulate the branch.
Implement this, because GCC 4.2 uses advanced loads regularly.
