[Qemu-devel] [PATCH v3 0/4] TriCore exception patches

[Bastian Koppelmann]

Hi,

this series add the infrastructure to generate and handle tricore exceptions
and adds three types of exceptions (context management,illegal opcodes, and
register-pair) which I tested so far. However more patches will follow that add
the missing exceptions that make sense to QEMU.

Cheers,
Bastian 

v2 -> v3:
     - raise_exception_sync_internal now directly modifies PC without
       using the do_interrupt hook
     - remove do_interrupt hook
     - add fcd_pc to raise_exception_sync_internal to be used by
       FCD traps
     - add raise_exception_sync_helper wrapper to be used by
       helper function that generate traps such that
       raise_exception_sync_internal is only directly called for FCD traps
     - add the generation of SOVF/OVF traps such that generate_trap()
       is used to avoid a unused function compiler warning.

v1 -> v2:
    - replace helper raise_exception_error by raise_exception_sync,
      that takes care of saving the pre-interrupt state for synchronous
      exceptions.
    - rewrite of generate_trap() in translate.c. It directly
      calls the raise_exception_sync helper instead of saving the
      pre-interrupt state itself.    
    - drop PATCH[2/5]: target-tricore: Save the pc before CSA operations for 
exceptions
