| -- This package contains the routine called when a fatal internal compiler |
| -- error is detected. Calls to this routines cause termination of the |
| -- current compilation with appropriate error output. |
| |
| package Comperr is |
| |
| procedure Compiler_Abort |
| (X : String; |
| Fallback_Loc : String := ""; |
| From_GCC : Boolean := False); |
| pragma No_Return (Compiler_Abort); |
| -- Signals an internal compiler error. Never returns control. Depending on |
| -- processing may end up raising Unrecoverable_Error, or exiting directly. |
| -- The message output is a "bug box" containing the first string passed as |
| -- an argument. The Sloc field of the node in Current_Error_Node is used to |
| -- provide the location where the error should be signalled. If this Sloc |
| -- value is set to No_Location or any of the other special location values, |
| -- then the Fallback_Loc argument string is used instead. The message text |
| -- includes the node id, and the code parameter if it is positive. |
| -- |
| -- Note that this is only used at the outer level (to handle constraint |
| -- errors or assert errors etc.) In the normal logic of the compiler we |
| -- always use pragma Assert to check for errors, and if necessary an |
| -- explicit abort is achieved by pragma Assert (False). From_GCC is true |
| -- for a GCC abort and false for a front end exception (with a possible |
| -- message stored in TSD.Current_Excep). |
| |
| -- WARNING: There is a matching C declaration of this subprogram in fe.h |
| |
| procedure Delete_SCIL_Files; |
| -- Delete SCIL files associated with the main unit |

| -- Use of gnat_bug.box File -- |
| ------------------------------ |
| |
| -- When comperr generates the "bug box". The first two lines contain |
| -- information on the version number, type of abort, and source location. |
| |
| -- Normally the remaining text is one of three possible forms |
| -- depending on Gnatvsn.Gnat_Version_Type (FSF, Public, GNATPRO). |
| -- See body of this package for the exact text used. |
| |
| -- In addition, an alternative mechanism exists for easily substituting |
| -- different text for this message. Compiler_Abort checks for the |
| -- existence of the file "gnat_bug.box" in the current source path. |
| -- Most typically this file, if present, will be in the directory |
| -- containing the run-time sources. |
| |
| -- If this file is present, then it is a plain ASCII file, whose contents |
| -- replace the remaining text. The lines in this file should be seventy-two |
| -- characters or less to avoid misformatting the right boundary of the box. |
| -- Note that the file does not contain the vertical bar characters or any |
| -- leading spaces in lines. |
