Index: ChangeLog from Benoît Perrot &lt;benoit(a)lrde.epita.fr&gt; Do not call exit_set inside control coprocessor * src/vm/cp0.hh, src/vm/cp0.hxx: (get_register) New. (raise_overflow, raise_addr_load, raise_addr_store): Activate fatal_exception_, remove call to exit_set. * src/vm/virtual_machine.cc: (execute) Use exit_set to report internal exception. 2006-01-08 Benoît Perrot &lt;benoit(a)lrde.epita.fr&gt; Index: src/vm/cp0.hh --- src/vm/cp0.hh (revision 210) +++ src/vm/cp0.hh (working copy) @@ -116,6 +116,8 @@ void set_register(const inst::Register &reg, register_type r); /// Return the register identified by \a reg. register_type get_register(const inst::Register &reg) const; + + register_type get_register(kind_type k) const; /** \} */ Index: src/vm/cp0.hxx --- src/vm/cp0.hxx (revision 210) +++ src/vm/cp0.hxx (working copy) @@ -69,6 +69,11 @@ precondition(reg.get_kind() == inst::Register::generic); return registers[reg.get_index()]; } + inline Cp0::register_type + Cp0::get_register(kind_type k) const + { + return registers[k]; + } // inline void @@ -76,7 +81,7 @@ { registers[cause] = overflow; std::cerr << "Runtime Exception: Overflow" << std::endl; - exit_set(exit_runtime); + fatal_exception_ = true; } inline void @@ -85,7 +90,6 @@ registers[cause] = addr_load; std::cerr << "Runtime Exception: Address error on load" << std::endl; fatal_exception_ = true; - exit_set(exit_runtime); } inline void Cp0::raise_addr_store() @@ -93,7 +97,6 @@ registers[cause] = addr_store; std::cerr << "Runtime Exception: Address error on store" << std::endl; fatal_exception_ = true; - exit_set(exit_runtime); } // Index: src/vm/virtual_machine.cc --- src/vm/virtual_machine.cc (revision 210) +++ src/vm/virtual_machine.cc (working copy) @@ -66,6 +66,10 @@ cpu_.step(); cp0_.set_count(cp0_.get_count() + 1); } + + // FIXME: this is not the good test, but for the moment it suffices + if (cp0_.get_register(Cp0::cause) != Cp0::interrupt) + exit_set(exit_runtime); } void
