From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/ada/comperr.ads | 76 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 76 insertions(+) create mode 100644 gcc/ada/comperr.ads (limited to 'gcc/ada/comperr.ads') diff --git a/gcc/ada/comperr.ads b/gcc/ada/comperr.ads new file mode 100644 index 000000000..04a606218 --- /dev/null +++ b/gcc/ada/comperr.ads @@ -0,0 +1,76 @@ +------------------------------------------------------------------------------ +-- -- +-- GNAT COMPILER COMPONENTS -- +-- -- +-- C O M P E R R -- +-- -- +-- S p e c -- +-- -- +-- Copyright (C) 1992-2007, Free Software Foundation, Inc. -- +-- -- +-- GNAT is free software; you can redistribute it and/or modify it under -- +-- terms of the GNU General Public License as published by the Free Soft- -- +-- ware Foundation; either version 3, or (at your option) any later ver- -- +-- sion.

Calls to this routines cause termination of the +-- current compilation with appropriate error output. + +package Comperr is + + procedure Compiler_Abort + (X : String; + Code : Integer := 0; + Fallback_Loc : String := ""); + -- 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). Code is positive + -- for a gigi abort (giving the gigi abort code), zero for a front + -- end exception (with possible message stored in TSD.Current_Excep, + -- and negative (an unused value) for a GCC abort. + + ------------------------------ + -- 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. + +end Comperr; -- cgit v1.2.3
