* a-except.adb, a-except.ads, a-except-2005.ads, a-except-2005.adb (Local_Raise): New dummy procedure called when a raise is converted to a local goto. Used for debugger to detect that the exception is raised. * debug.adb: Document new d.g flag (expand local raise statements to gotos even if pragma Restriction (No_Exception_Propagation) is not set) * exp_sel.adb: Use Make_Implicit_Exception_Handler * exp_ch11.adb (Expand_Exception_Handlers): Use new flag -gnatw.x to suppress warnings for unused handlers. (Warn_If_No_Propagation): Use new flag -gnatw.x to suppress warnings for raise statements not handled locally. (Get_RT_Exception_Entity): New function (Get_Local_Call_Entity): New function (Find_Local_Handler): New function (Warn_If_No_Propagation): New procedure (Expand_At_End_Handler): Call Make_Implicit_Handler (Expand_Exception_Handlers): Major additions to deal with local handlers (Expand_N_Raise_Constraint_Error, Expand_N_Raise_Program_Error, Expand_N_Raise_Storage_Error, (Expand_N_Raise_Statement): Add handling for local raise * exp_ch11.ads (Get_RT_Exception_Entity): New function (Get_Local_Call_Entity): New function * gnatbind.adb (Restriction_List): Add No_Exception_Propagation to list of restrictions that the binder will never suggest adding. * par-ch11.adb (P_Exception_Handler): Set Local_Raise_Statements field to No_Elist. * restrict.adb (Check_Restricted_Unit): GNAT.Current_Exception may not be with'ed in the presence of pragma Restriction (No_Exception_Propagation). * sem.adb (Analyze): Add entries for N_Push and N_Pop nodes * sem_ch11.adb (Analyze_Exception_Handler): If there is a choice parameter, then the handler is not a suitable target for a local raise, and this is a violation of restriction No_Exception_Propagation. (Analyze_Handled_Statements): Analyze choice parameters in exception handlers before analyzing statement sequence (needed for proper detection of local raise statements). (Analyze_Raise_Statement): Reraise statement is a violation of the No_Exception_Propagation restriction. * s-rident.ads: Add new restriction No_Exception_Propagation * tbuild.ads, tbuild.adb (Make_Implicit_Exception_Handler): New function, like Make_Exception_Handler but sets Local_Raise_Statements to No_List. (Add_Unique_Serial_Number): Deal with case where this is called during processing of configuration pragmas. From-SVN: r123541 |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
