-For front-ends that support it (C and C++), instrument all risky

-string/heap functions, and some other associated constructs with
-range/validity tests. Modules so instrumented should be immune to
-buffer overflows, invalid heap use, and some other classes of C/C++
-programming errors. The instrumentation relies on a separate runtime
-library (@file{libmudflap}), which is linked into a program if
-@option{-fmudflap} is given at link time. Run-time behavior of the
-instrumented program is controlled by the @env{MUDFLAP_OPTIONS}
-environment variable. See @code{env MUDFLAP_OPTIONS=-help a.out}
-for its options.
-
-Use @option{-fmudflapth} instead of @option{-fmudflap} to compile and to
-link if your program is multi-threaded. Use @option{-fmudflapir}, in
-addition to @option{-fmudflap} or @option{-fmudflapth}, if
-instrumentation should ignore pointer reads. This produces less
-instrumentation (and therefore faster execution) and still provides
-some protection against outright memory corrupting writes, but allows
-erroneously read data to propagate within a program.

-enabled, we generate code to register some variable declarations with
-the mudflap runtime. Specifically, the runtime tracks the lifetimes of

-bounds are unknown at compile time (@code{extern}). This pass generates
-new exception handling constructs (@code{try}/@code{finally}), and so
-must run before those are lowered. In addition, the pass enqueues

-
-If mudflap is enabled, we rewrite some memory accesses with code to
-validate that the memory access is correct. In particular, expressions
-involving pointer dereferences (@code{INDIRECT_REF}, @code{ARRAY_REF},
-etc.) are replaced by code that checks the selected address range
-against the mudflap runtime's database of valid regions. This check
-includes an inline lookup into a direct-mapped cache, based on
-shift/mask operations of the pointer value, with a fallback function
-call into the runtime. The pass is located in @file{tree-mudflap.c} and
-is described by @code{pass_mudflap_2}.

@item Leave static single assignment form
This pass rewrites the function such that it is in normal form. At
are @file{final.c} plus @file{insn-output.c}; the latter is generated
automatically from the machine description by the tool @file{genoutput}.
The header file @file{conditions.h} is used for communication between
-these files. If mudflap is enabled, the queue of deferred declarations
-and any addressed constants (e.g., string literals) is processed by
-@code{mudflap_finish_file} into a synthetic constructor function

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
-# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory. The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run. This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-# fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-# fails if $ac_aux_dir is absolute,
-# fails when called from a subdirectory in a VPATH build with
-# a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir. In an in-source build this is usually
-# harmless because $srcdir is `.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
-# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-# MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH. The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

-\`configure' configures libmudflap 1.0 to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE. See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
- -h, --help display this help and exit
- --help=short display options specific to this package
- --help=recursive display the short help of all the included packages
- -V, --version display version information and exit
- -q, --quiet, --silent do not print \`checking...' messages
- --cache-file=FILE cache test results in FILE [disabled]
- -C, --config-cache alias for \`--cache-file=config.cache'
- -n, --no-create do not create output files
- --srcdir=DIR find the sources in DIR [configure dir or \`..']
-
-Installation directories:
- --prefix=PREFIX install architecture-independent files in PREFIX
- [$ac_default_prefix]
- --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
- [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
- --bindir=DIR user executables [EPREFIX/bin]
- --sbindir=DIR system admin executables [EPREFIX/sbin]
- --libexecdir=DIR program executables [EPREFIX/libexec]
- --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
- --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
- --localstatedir=DIR modifiable single-machine data [PREFIX/var]
- --libdir=DIR object code libraries [EPREFIX/lib]
- --includedir=DIR C header files [PREFIX/include]
- --oldincludedir=DIR C header files for non-gcc [/usr/include]
- --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
- --datadir=DIR read-only architecture-independent data [DATAROOTDIR]

- --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
- --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
- --enable-version-specific-runtime-libs Specify that runtime libraries should be installed in a compiler-specific directory
- --enable-maintainer-mode enable make rules and dependencies not useful
- (and sometimes confusing) to the casual installer
- --enable-multilib build many library versions (default)
- --disable-dependency-tracking speeds up one-time build
- --enable-dependency-tracking do not reject slow dependency extractors
- --enable-shared[=PKGS] build shared libraries [default=yes]
- --enable-static[=PKGS] build static libraries [default=yes]
- --enable-fast-install[=PKGS]
- optimize for fast installation [default=yes]
- --disable-libtool-lock avoid locking (might break parallel builds)
- --enable-tls Use thread-local storage [default=yes]
-
-Optional Packages:
- --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
- --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
- --with-pic try to use only PIC/non-PIC objects [default=use
- both]
- --with-gnu-ld assume the C compiler uses GNU ld [default=no]
-
-Some influential environment variables:
- CC C compiler command
- CFLAGS C compiler flags
- LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
- nonstandard directory <lib dir>
- LIBS libraries to pass to the linker, e.g. -l<library>
- CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
- you have headers in a nonstandard directory <include dir>
- CPP C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.
-
-Report bugs to the package provider.

- Wrapping and redirection:
-
- Mudflap redirects a number of libc functions into itself, for "cheap"
- verification (eg. strcpy, bzero, memcpy) and also to register /
- unregister regions of memory as they are manipulated by the program
- (eg. malloc/free, mmap/munmap).
-
- There are two methods of wrapping.
-
- (1) The static method involves a list of -wrap=foo flags being passed to
- the linker, which then links references to "foo" to the symbol
- "__wrap_foo", and links references to "__real_foo" to the symbol "foo".
- When compiled without -DPIC, libmudflap.a contains such __wrap_foo
- functions which delegate to __real_foo functions in libc to get their
- work done.
-
- (2) The dynamic method involves providing a definition of symbol foo in
- libmudflap.so and linking it earlier in the compiler command line,
- before libc.so. The function "foo" in libmudflap must then call
- dlsym(RTLD_NEXT, "foo") to acquire a pointer to the "real" libc foo, or
- at least the "next" foo in the dynamic link resolution order.
-
- We switch between these two techniques by the presence of the -DPIC
- #define passed in by libtool when building libmudflap.
