+I am happy to introduce GHDL.
+
+GHDL is a GCC front-end for the VHDL (IEEE 1076) language, an hardware design
+language.
+
+Currently, GHDL implements most of VHDL-1987 and some features of
+VHDL-1993.  It is mature enough to compile and run some complex design (such
+as a DLX processor and leon1, a SPARCv7 processor)
+
+GHDL has been developped on a GNU/Linux x86 system, and only this configuration
+has been tested (porting to other processor or system should not be an hard
+task, but there are system dependent files in the run time).
+
+GHDL is written in Ada95 (using GNAT) and relies on agcc, an Ada
+binding for GCC.  It also includes a run-time library (written in Ada), named
+grt.  The front-end and the library are both distributed under the GPL licence.
+
+For sources, binary tarballs, or for more information, go to
+http://ghdl.free.fr

+# The makefile built from this file lives in the language subdirectory.
+# It's purpose is to provide support for:
+#
+# 1) recursion where necessary, and only then (building .o's), and
+# 2) building and debugging cc1 from the language subdirectory, and
+# 3) nothing else.
+#
+# The parent makefile handles all other chores, with help from the
+# language makefile fragment, of course.
+#
+# The targets for external use are:
+# all, TAGS, ???mostlyclean, ???clean.
+
+# This makefile will only work with Gnu make.
+# The rules are written assuming a minimum subset of tools are available:
+#
+# Required:
+#      MAKE:    Only Gnu make will work.
+#      MV:      Must accept (at least) one, maybe wildcard, source argument,
+#               a file or directory destination, and support creation/
+#               modification date preservation.  Gnu mv -f works.
+#      RM:      Must accept an arbitrary number of space separated file
+#               arguments, or one wildcard argument. Gnu rm works.
+#      RMDIR:   Must delete a directory and all its contents. Gnu rm -rf works.
+#      ECHO:    Must support command line redirection. Any Unix-like
+#               shell will typically provide this, otherwise a custom version
+#               is trivial to write.
+#      LN:      ln -s works, cp should work bu was not tested.
+#      CP:      GNU cp -p works.
+#      AR:      Gnu ar works.
+#      MKDIR:   Gnu mkdir works.
+#      CHMOD:   Gnu chmod works.
+#      true:    Does nothing and returns a normal successful return code.
+#      pwd:     Prints the current directory on stdout.
+#      cd:      Change directory.

+
+Building GHDL from sources:
+***************************
+
+Required:
+* the sources of @GCCVERSION@ (at least the core part).
+  Note: other versions of gcc sources have not been tested.
+* the Ada95 GNAT compiler (GNAT GPL 2008 are known to work;
+  Ada compilers in most Linux distributions are more or less buggy)
+* GNU/Linux for ix86 (pc systems) (porting is necessary for other systems)
+
+Procedure:
+* Check your Ada compiler.  On some systems (or with some distribution), the
+  GNAT compiler seems broken.  Try this very simple example, using file
+  example.adb
+<<<<<<<<<<<<<<<<<<
+procedure Example is
+begin
+   null;
+end Example;
+<<<<<<<<<<<<<<<<<<
+  Compile with
+  $ gnatmake example
+  It should create an executable, 'example'.
+  If this doesn't work, your GNAT installation is broken.  It may be a PATH
+  problem or something else.
+* untar the gcc tarball
+* untar the ghdl tarball (this sould have been done, since you are reading a
+  file from it).
+* move or copy the vhdl directory of ghdl into the gcc subdirectory of
+  the gcc distribution.
+  You should have a @GCCVERSION@/gcc/vhdl directory.
+* configure gcc with the --enable-languages=vhdl option.  You may of course
+  add other languages.  Also you'd better to disable bootstraping using
+  --disable-bootstrap.
+  Refer to the gcc installation documentation.
+* compile gcc.
+  'make CFLAGS="-O"' is OK
+* install gcc.  This installs the ghdl driver too.
+  'make install' is OK.
+
+There is a mailing list for any questions.  You can subscribe via:
+  https://mail.gna.org/listinfo/ghdl-discuss/
+Please report bugs on https://gna.org/bugs/?group=ghdl
+
+If you cannot compile, please report the gcc version, GNAT version and gcc
+source version.
+
+* Note for ppc64 (and AIX ?) platform:
+The object file format contains an identifier for the source language. Because
+gcc doesn't know about the VHDL, gcc crashes very early. This could be fixed
+with a very simple change in gcc/config/rs6000/rs6000.c,
+function rs6000_output_function_epilogue (as of gcc 4.8):
+       else if (! strcmp (language_string, "GNU Objective-C"))
+        i = 14;
+       else
+-       gcc_unreachable ();
++       i = 0;
+       fprintf (file, "%d,", i);
+
+       /* 8 single bit fields: global linkage (not set for C extern linkage,
