Abstract:
|
|
|
|
Main entrypoints for IA64 ia64bt.dll. This code is really a dummy
|
|
and a user can put in a real dll at a later date. As long as the
|
|
entry points exist, we are fine. It is delay loaded by
|
|
wow64cpu depending on whether the binary translation code is
|
|
enabled.

Routine Description:
|
|
|
|
After an exception occurs, WOW64 calls this routine to give the CPU
|
|
a chance to clean itself up and recover the CONTEXT32 at the time of
|
|
the fault.
|
|
|
|
CpuResetToConsistantState() needs to:
|
|
|
|
0) Check if the exception was from ia32 or ia64
|
|
|
|
If exception was ia64, do nothing and return
|
|
If exception was ia32, needs to:
|
|
1) Needs to copy CONTEXT eip to the TLS (WOW64_TLS_EXCEPTIONADDR)
|
|
2) reset the CONTEXT struction to be a valid ia64 state for unwinding
|
|
this includes:
|
|
2a) reset CONTEXT ip to a valid ia64 ip (usually
|
|
the destination of the jmpe)
|
|
2b) reset CONTEXT sp to a valid ia64 sp (TLS
|
|
entry WOW64_TLS_STACKPTR64)
|
|
2c) reset CONTEXT gp to a valid ia64 gp
|
|
2d) reset CONTEXT teb to a valid ia64 teb
|
|
2e) reset CONTEXT psr.is (so exception handler runs as ia64 code)
