+@c This is part of the GCC manual.
+@c For copying conditions, see the file gcc.texi.
+
+@node Makefile
+@subsection Makefile Targets
+@cindex makefile targets
+@cindex targets, makefile
+
+@table @code
+@item all
+This is the default target.  Depending on what your build/host/target
+configuration is, it coordinates all the things that need to be built.
+
+@item doc
+Produce info-formatted documentation.  Also, @code{make dvi} is
+available for DVI-formatted documentation, and @code{make
+generated-manpages} to generate man pages.
+
+@item mostlyclean
+Delete the files made while building the compiler.
+
+@item clean
+That, and all the other files built by @code{make all}.
+
+@item distclean
+That, and all the files created by @code{configure}.
+
+@item extraclean
+That, and any temporary or intermediate files, like emacs backup files.
+
+@item maintainer-clean
+Distclean plus any file that can be generated from other files.  Note
+that additional tools may be required beyond what is normally needed to
+build gcc.
+
+@item install
+Installs gcc.
+
+@item uninstall
+Deletes installed files.
+
+@item check
+Run the testsuite.  This creates a @file{testsuite} subdirectory that
+has various @file{.sum} and @file{.log} files containing the results of
+the testing.  You can run subsets with, for example, @code{make check-gcc}.
+You can specify specific tests by setting RUNTESTFLAGS to be the name
+of the @file{.exp} file, optionally followed by (for some tests) an equals
+and a file wildcard, like:
+
+@example
+make check-gcc RUNTESTFLAGS="execute.exp=19980413-*"
+@end example
+
+Note that running the testsuite may require additional tools be
+installed, such as TCL or dejagnu.
+
+@item bootstrap
+Builds gcc three times---once with the native compiler, once with the
+native-built compiler it just built, and once with the compiler it built
+the second time.  In theory, the last two should produce the same
+results, which @code{make compare} can check.  Each step of this process
+is called a ``stage'', and the results of each stage @var{N}
+(@var{N} = 1@dots{}3) are copied to a subdirectory @file{stage@var{N}/}.
+
+@item bootstrap-lean
+Like @code{bootstrap}, except that the various stages are removed once
+they're no longer needed.  This saves disk space.
+
+@item bubblestrap
+Once bootstrapped, this incrementally rebuilds each of the three stages,
+one at a time.  It does this by ``bubbling'' the stages up from their
+subdirectories, rebuilding them, and copying them back to their
+subdirectories.  This will allow you to, for example, quickly rebuild a
+bootstrapped compiler after changing the sources, without having to do a
+full bootstrap.
+
+@item quickstrap
+Rebuilds the most recently built stage.  Since each stage requires
+special invocation, using this target means you don't have to keep track
+of which stage you're on or what invocation that stage needs.
+
+@item cleanstrap
+Removed everything (@code{make clean}) and rebuilds (@code{make bootstrap}).
+
+@item stage@var{N} (@var{N} = 1@dots{}4)
+For each stage, moves the appropriate files to the @file{stage@var{N}}
+subdirectory.
+
+@item unstage@var{N} (@var{N} = 1@dots{}4)
+Undoes the corresponding @code{stage@var{N}}.
+
+@item restage@var{N} (@var{N} = 1@dots{}4)
+Undoes the corresponding @code{stage@var{N}} and rebuilds it with the
+appropriate flags.
+
+@item compare
+Compares the results of stages 2 and 3.  This ensures that the compiler
+is running properly, since it should produce the same object files
+regardless of how it itself was compiled.
