2007-04-20 Thomas Quinot <quinot@adacore.com> Olivier Hainque <hainque@adacore.com> Robert Dewar <dewar@adacore.com> * a-except.ads, a-except.adb: (Rmsg_28): Fix description for E.4(18) check. (Raise_Current_Excep): Call Debug_Raise_Exception just before propagation starts, to let debuggers know about the event in a reliable fashion. (Local_Raise): Moved to System.Exceptions More convenient to have this as a separate unit * s-except.adb, s-except.ads: New files. * a-exextr.adb (Unhandled_Exception): Delete - replaced by Debug_Unhandled_Exception in System.Exceptions where it belongs together with a couple of other debug helpers. (Notify_Unhandled_Exception): Use Debug_Unhandled_Exception instead of the former Unhandled_Exception. * exp_ch11.ads, exp_ch11.adb: (Possible_Local_Raise): New procedure (Warn_No_Exception_Propagation): New procedure (Warn_If_No_Propagation): Rewritten for new warning generation (Expand_Exception_Handlers): New warning generation (Expand_N_Raise_xxx_Error): Rewritten for new warnings (Add_Exception_Label): Use Special_Exception_Package_Used for test instead of Most_Recent_Exception_Used (accomodates Exception_Traces) (Expand_Local_Exception_Handlers): Unconditionally add extra block wrap even if restriction is set (makes life easier in Check_Returns) (Expand_Local_Exception_Handlers): Follow renamed entity chain when checking exception identities. (Expand_Local_Exception_Handlers): Do not optimize when all others case (Expand_Local_Exception_Handlers): Set Exception_Junk flag on generated block for handler (used by Check_Returns) (Expand_Local_Exception_Handlers): Local_Raise now takes an address (Expand_N_Handled_Sequence_Of_Statements): Properly handle -gnatd.x to remove all exception handlers when optimizing local raise statements. (Find_Local_Handler): Use Get_Renamed_Entity (Expand_N_Handled_Sequence_Of_Statements): If the handled sequence is marked analyzed after expanding exception handlers, do not generate redundant cleanup actions, because they have been constructed already.
