Merge branch 'rc-4.5.0'

This avoids signed/unsigned comparison warnings when specifying integer
constants as inputs.

Clean up whitespace and add clarifying parentheses for
CONF_HANDLE_SIZE_T(opt_lg_chunk, ...).

INSTALL

@@ -0,0 +1,434 @@
+Building and installing a packaged release of jemalloc can be as simple as
+typing the following while in the root directory of the source tree:
+
+    ./configure
+    make
+    make install
+
+If building from unpackaged developer sources, the simplest command sequence
+that might work is:
+
+    ./autogen.sh
+    make dist
+    make
+    make install
+
+Note that documentation is not built by the default target because doing so
+would create a dependency on xsltproc in packaged releases, hence the
+requirement to either run 'make dist' or avoid installing docs via the various
+install_* targets documented below.
+
+=== Advanced configuration =====================================================
+
+The 'configure' script supports numerous options that allow control of which
+functionality is enabled, where jemalloc is installed, etc.  Optionally, pass
+any of the following arguments (not a definitive list) to 'configure':
+
+--help
+    Print a definitive list of options.
+
+--prefix=<install-root-dir>
+    Set the base directory in which to install.  For example:
+
+        ./configure --prefix=/usr/local
+
+    will cause files to be installed into /usr/local/include, /usr/local/lib,
+    and /usr/local/man.
+
+--with-version=<major>.<minor>.<bugfix>-<nrev>-g<gid>
+    Use the specified version string rather than trying to generate one (if in
+    a git repository) or use existing the VERSION file (if present).
+
+--with-rpath=<colon-separated-rpath>
+    Embed one or more library paths, so that libjemalloc can find the libraries
+    it is linked to.  This works only on ELF-based systems.
+
+--with-mangling=<map>
+    Mangle public symbols specified in <map> which is a comma-separated list of
+    name:mangled pairs.
+
+    For example, to use ld's --wrap option as an alternative method for
+    overriding libc's malloc implementation, specify something like:
+
+      --with-mangling=malloc:__wrap_malloc,free:__wrap_free[...]
+
+    Note that mangling happens prior to application of the prefix specified by
+    --with-jemalloc-prefix, and mangled symbols are then ignored when applying
+    the prefix.
+
+--with-jemalloc-prefix=<prefix>
+    Prefix all public APIs with <prefix>.  For example, if <prefix> is
+    "prefix_", API changes like the following occur:
+
+      malloc()         --> prefix_malloc()
+      malloc_conf      --> prefix_malloc_conf
+      /etc/malloc.conf --> /etc/prefix_malloc.conf
+      MALLOC_CONF      --> PREFIX_MALLOC_CONF
+
+    This makes it possible to use jemalloc at the same time as the system
+    allocator, or even to use multiple copies of jemalloc simultaneously.
+
+    By default, the prefix is "", except on OS X, where it is "je_".  On OS X,
+    jemalloc overlays the default malloc zone, but makes no attempt to actually
+    replace the "malloc", "calloc", etc. symbols.
+
+--without-export
+    Don't export public APIs.  This can be useful when building jemalloc as a
+    static library, or to avoid exporting public APIs when using the zone
+    allocator on OSX.
+
+--with-private-namespace=<prefix>
+    Prefix all library-private APIs with <prefix>je_.  For shared libraries,
+    symbol visibility mechanisms prevent these symbols from being exported, but
+    for static libraries, naming collisions are a real possibility.  By
+    default, <prefix> is empty, which results in a symbol prefix of je_ .
+
+--with-install-suffix=<suffix>
+    Append <suffix> to the base name of all installed files, such that multiple
+    versions of jemalloc can coexist in the same installation directory.  For
+    example, libjemalloc.so.0 becomes libjemalloc<suffix>.so.0.
+
+--with-malloc-conf=<malloc_conf>
+    Embed <malloc_conf> as a run-time options string that is processed prior to
+    the malloc_conf global variable, the /etc/malloc.conf symlink, and the
+    MALLOC_CONF environment variable.  For example, to change the default chunk
+    size to 256 KiB:
+
+      --with-malloc-conf=lg_chunk:18
+
+--disable-cc-silence
+    Disable code that silences non-useful compiler warnings.  This is mainly
+    useful during development when auditing the set of warnings that are being
+    silenced.
+
+--enable-debug
+    Enable assertions and validation code.  This incurs a substantial
+    performance hit, but is very useful during application development.
+    Implies --enable-ivsalloc.
+
+--enable-code-coverage
+    Enable code coverage support, for use during jemalloc test development.
+    Additional testing targets are available if this option is enabled:
+
+      coverage
+      coverage_unit
+      coverage_integration
+      coverage_stress
+
+    These targets do not clear code coverage results from previous runs, and
+    there are interactions between the various coverage targets, so it is
+    usually advisable to run 'make clean' between repeated code coverage runs.
+
+--disable-stats
+    Disable statistics gathering functionality.  See the "opt.stats_print"
+    option documentation for usage details.
+
+--enable-ivsalloc
+    Enable validation code, which verifies that pointers reside within
+    jemalloc-owned chunks before dereferencing them.  This incurs a minor
+    performance hit.
+
+--enable-prof
+    Enable heap profiling and leak detection functionality.  See the "opt.prof"
+    option documentation for usage details.  When enabled, there are several
+    approaches to backtracing, and the configure script chooses the first one
+    in the following list that appears to function correctly:
+
+    + libunwind      (requires --enable-prof-libunwind)
+    + libgcc         (unless --disable-prof-libgcc)
+    + gcc intrinsics (unless --disable-prof-gcc)
+
+--enable-prof-libunwind
+    Use the libunwind library (http://www.nongnu.org/libunwind/) for stack
+    backtracing.
+
+--disable-prof-libgcc
+    Disable the use of libgcc's backtracing functionality.
+
+--disable-prof-gcc
+    Disable the use of gcc intrinsics for backtracing.
+
+--with-static-libunwind=<libunwind.a>
+    Statically link against the specified libunwind.a rather than dynamically
+    linking with -lunwind.
+
+--disable-tcache
+    Disable thread-specific caches for small objects.  Objects are cached and
+    released in bulk, thus reducing the total number of mutex operations.  See
+    the "opt.tcache" option for usage details.
+
+--disable-thp
+    Disable transparent huge page (THP) integration.  On systems with THP
+    support, THPs are explicitly disabled as a side effect of unused dirty page
+    purging for chunks that back small and/or large allocations, because such
+    chunks typically comprise active, unused dirty, and untouched clean
+    pages.
+
+--disable-munmap
+    Disable virtual memory deallocation via munmap(2); instead keep track of
+    the virtual memory for later use.  munmap() is disabled by default (i.e.
+    --disable-munmap is implied) on Linux, which has a quirk in its virtual
+    memory allocation algorithm that causes semi-permanent VM map holes under
+    normal jemalloc operation.
+
+--disable-fill
+    Disable support for junk/zero filling of memory, quarantine, and redzones.
+    See the "opt.junk", "opt.zero", "opt.quarantine", and "opt.redzone" option
+    documentation for usage details.
+
+--disable-valgrind
+    Disable support for Valgrind.
+
+--disable-zone-allocator
+    Disable zone allocator for Darwin.  This means jemalloc won't be hooked as
+    the default allocator on OSX/iOS.
+
+--enable-utrace
+    Enable utrace(2)-based allocation tracing.  This feature is not broadly
+    portable (FreeBSD has it, but Linux and OS X do not).
+
+--enable-xmalloc
+    Enable support for optional immediate termination due to out-of-memory
+    errors, as is commonly implemented by "xmalloc" wrapper function for malloc.
+    See the "opt.xmalloc" option documentation for usage details.
+
+--enable-lazy-lock
+    Enable code that wraps pthread_create() to detect when an application
+    switches from single-threaded to multi-threaded mode, so that it can avoid
+    mutex locking/unlocking operations while in single-threaded mode.  In
+    practice, this feature usually has little impact on performance unless
+    thread-specific caching is disabled.
+
+--disable-tls
+    Disable thread-local storage (TLS), which allows for fast access to
+    thread-local variables via the __thread keyword.  If TLS is available,
+    jemalloc uses it for several purposes.
+
+--disable-cache-oblivious
+    Disable cache-oblivious large allocation alignment for large allocation
+    requests with no alignment constraints.  If this feature is disabled, all
+    large allocations are page-aligned as an implementation artifact, which can
+    severely harm CPU cache utilization.  However, the cache-oblivious layout
+    comes at the cost of one extra page per large allocation, which in the
+    most extreme case increases physical memory usage for the 16 KiB size class
+    to 20 KiB.
+
+--disable-syscall
+    Disable use of syscall(2) rather than {open,read,write,close}(2).  This is
+    intended as a workaround for systems that place security limitations on
+    syscall(2).
+
+--with-xslroot=<path>
+    Specify where to find DocBook XSL stylesheets when building the
+    documentation.
+
+--with-lg-page=<lg-page>
+    Specify the base 2 log of the system page size.  This option is only useful
+    when cross compiling, since the configure script automatically determines
+    the host's page size by default.
+
+--with-lg-page-sizes=<lg-page-sizes>
+    Specify the comma-separated base 2 logs of the page sizes to support.  This
+    option may be useful when cross-compiling in combination with
+    --with-lg-page, but its primary use case is for integration with FreeBSD's
+    libc, wherein jemalloc is embedded.
+
+--with-lg-size-class-group=<lg-size-class-group>
+    Specify the base 2 log of how many size classes to use for each doubling in
+    size.  By default jemalloc uses <lg-size-class-group>=2, which results in
+    e.g. the following size classes:
+
+      [...], 64,
+      80, 96, 112, 128,
+      160, [...]
+
+    <lg-size-class-group>=3 results in e.g. the following size classes:
+
+      [...], 64,
+      72, 80, 88, 96, 104, 112, 120, 128,
+      144, [...]
+
+    The minimal <lg-size-class-group>=0 causes jemalloc to only provide size
+    classes that are powers of 2:
+
+      [...],
+      64,
+      128,
+      256,
+      [...]
+
+    An implementation detail currently limits the total number of small size
+    classes to 255, and a compilation error will result if the
+    <lg-size-class-group> you specify cannot be supported.  The limit is
+    roughly <lg-size-class-group>=4, depending on page size.
+
+--with-lg-quantum=<lg-quantum>
+    Specify the base 2 log of the minimum allocation alignment.  jemalloc needs
+    to know the minimum alignment that meets the following C standard
+    requirement (quoted from the April 12, 2011 draft of the C11 standard):
+
+      The pointer returned if the allocation succeeds is suitably aligned so
+      that it may be assigned to a pointer to any type of object with a
+      fundamental alignment requirement and then used to access such an object
+      or an array of such objects in the space allocated [...]
+
+    This setting is architecture-specific, and although jemalloc includes known
+    safe values for the most commonly used modern architectures, there is a
+    wrinkle related to GNU libc (glibc) that may impact your choice of
+    <lg-quantum>.  On most modern architectures, this mandates 16-byte alignment
+    (<lg-quantum>=4), but the glibc developers chose not to meet this
+    requirement for performance reasons.  An old discussion can be found at
+    https://sourceware.org/bugzilla/show_bug.cgi?id=206 .  Unlike glibc,
+    jemalloc does follow the C standard by default (caveat: jemalloc
+    technically cheats if --with-lg-tiny-min is smaller than
+    --with-lg-quantum), but the fact that Linux systems already work around
+    this allocator noncompliance means that it is generally safe in practice to
+    let jemalloc's minimum alignment follow glibc's lead.  If you specify
+    --with-lg-quantum=3 during configuration, jemalloc will provide additional
+    size classes that are not 16-byte-aligned (24, 40, and 56, assuming
+    --with-lg-size-class-group=2).
+
+--with-lg-tiny-min=<lg-tiny-min>
+    Specify the base 2 log of the minimum tiny size class to support.  Tiny
+    size classes are powers of 2 less than the quantum, and are only
+    incorporated if <lg-tiny-min> is less than <lg-quantum> (see
+    --with-lg-quantum).  Tiny size classes technically violate the C standard
+    requirement for minimum alignment, and crashes could conceivably result if
+    the compiler were to generate instructions that made alignment assumptions,
+    both because illegal instruction traps could result, and because accesses
+    could straddle page boundaries and cause segmentation faults due to
+    accessing unmapped addresses.
+
+    The default of <lg-tiny-min>=3 works well in practice even on architectures
+    that technically require 16-byte alignment, probably for the same reason
+    --with-lg-quantum=3 works.  Smaller tiny size classes can, and will, cause
+    crashes (see https://bugzilla.mozilla.org/show_bug.cgi?id=691003 for an
+    example).
+
+    This option is rarely useful, and is mainly provided as documentation of a
+    subtle implementation detail.  If you do use this option, specify a
+    value in [3, ..., <lg-quantum>].
+
+The following environment variables (not a definitive list) impact configure's
+behavior:
+
+CFLAGS="?"
+    Pass these flags to the C compiler.  Any flags set by the configure script
+    are prepended, which means explicitly set flags generally take precedence.
+    Take care when specifying flags such as -Werror, because configure tests may
+    be affected in undesirable ways.
+
+EXTRA_CFLAGS="?"
+    Append these flags to CFLAGS, without passing them to the compiler during
+    configuration.  This makes it possible to add flags such as -Werror, while
+    allowing the configure script to determine what other flags are appropriate
+    for the specified configuration.
+
+CPPFLAGS="?"
+    Pass these flags to the C preprocessor.  Note that CFLAGS is not passed to
+    'cpp' when 'configure' is looking for include files, so you must use
+    CPPFLAGS instead if you need to help 'configure' find header files.
+
+LD_LIBRARY_PATH="?"
+    'ld' uses this colon-separated list to find libraries.
+
+LDFLAGS="?"
+    Pass these flags when linking.
+
+PATH="?"
+    'configure' uses this to find programs.
+
+In some cases it may be necessary to work around configuration results that do
+not match reality.  For example, Linux 4.5 added support for the MADV_FREE flag
+to madvise(2), which can cause problems if building on a host with MADV_FREE
+support and deploying to a target without.  To work around this, use a cache
+file to override the relevant configuration variable defined in configure.ac,
+e.g.:
+
+    echo "je_cv_madv_free=no" > config.cache && ./configure -C
+
+=== Advanced compilation =======================================================
+
+To build only parts of jemalloc, use the following targets:
+
+    build_lib_shared
+    build_lib_static
+    build_lib
+    build_doc_html
+    build_doc_man
+    build_doc
+
+To install only parts of jemalloc, use the following targets:
+
+    install_bin
+    install_include
+    install_lib_shared
+    install_lib_static
+    install_lib
+    install_doc_html
+    install_doc_man
+    install_doc
+
+To clean up build results to varying degrees, use the following make targets:
+
+    clean
+    distclean
+    relclean
+
+=== Advanced installation ======================================================
+
+Optionally, define make variables when invoking make, including (not
+exclusively):
+
+INCLUDEDIR="?"
+    Use this as the installation prefix for header files.
+
+LIBDIR="?"
+    Use this as the installation prefix for libraries.
+
+MANDIR="?"
+    Use this as the installation prefix for man pages.
+
+DESTDIR="?"
+    Prepend DESTDIR to INCLUDEDIR, LIBDIR, DATADIR, and MANDIR.  This is useful
+    when installing to a different path than was specified via --prefix.
+
+CC="?"
+    Use this to invoke the C compiler.
+
+CFLAGS="?"
+    Pass these flags to the compiler.
+
+CPPFLAGS="?"
+    Pass these flags to the C preprocessor.
+
+LDFLAGS="?"
+    Pass these flags when linking.
+
+PATH="?"
+    Use this to search for programs used during configuration and building.
+
+=== Development ================================================================
+
+If you intend to make non-trivial changes to jemalloc, use the 'autogen.sh'
+script rather than 'configure'.  This re-generates 'configure', enables
+configuration dependency rules, and enables re-generation of automatically
+generated source files.
+
+The build system supports using an object directory separate from the source
+tree.  For example, you can create an 'obj' directory, and from within that
+directory, issue configuration and build commands:
+
+    autoconf
+    mkdir obj
+    cd obj
+    ../configure --enable-autogen
+    make
+
+=== Documentation ==============================================================
+
+The manual page is generated in both html and roff formats.  Any web browser
+can be used to view the html manual.  The roff manual page can be formatted
+prior to installation via the following command:
+
+    nroff -man -t doc/jemalloc.3

+jemalloc is a general purpose malloc(3) implementation that emphasizes
+fragmentation avoidance and scalable concurrency support.  jemalloc first came
+into use as the FreeBSD libc allocator in 2005, and since then it has found its
+way into numerous applications that rely on its predictable behavior.  In 2010
+jemalloc development efforts broadened to include developer support features
+such as heap profiling, Valgrind integration, and extensive monitoring/tuning
+hooks.  Modern jemalloc releases continue to be integrated back into FreeBSD,
+and therefore versatility remains critical.  Ongoing development efforts trend
+toward making jemalloc among the best allocators for a broad range of demanding
+applications, and eliminating/mitigating weaknesses that have practical
+repercussions for real world applications.
+
+The COPYING file contains copyright and licensing information.
+
+The INSTALL file contains information on how to configure, build, and install
+jemalloc.
+
+The ChangeLog file contains a brief summary of changes for each release.

+ *   malloc_tsd_data(, example_, example_t, EX_INITIALIZER)
+ *   malloc_tsd_funcs(, example_, example_t, EX_INITIALIZER,
+ *       example_tsd_cleanup)

+ *   bool example_tsd_booted_get(void) {...}
+ *   example_t *example_tsd_get(bool init) {...}
+ *   void example_tsd_set(example_t *val) {...}
+ *
+ * Note that all of the functions deal in terms of (a_type *) rather than
+ * (a_type) so that it is possible to support non-pointer types (unlike
+ * pthreads TSD).  example_tsd_cleanup() is passed an (a_type *) pointer that is
+ * cast to (void *).  This means that the cleanup function needs to cast the
+ * function argument to (a_type *), then dereference the resulting pointer to
+ * access fields, e.g.
+ *
+ *   void
+ *   example_tsd_cleanup(void *arg)

+ *
+ *           example->x = 42;

+ *           if ([want the cleanup function to be called again])
+ *                   example_tsd_set(example);
+ *   }
+ *
+ * If example_tsd_set() is called within example_tsd_cleanup(), it will be
+ * called again.  This is similar to how pthreads TSD destruction works, except
+ * that pthreads only calls the cleanup function again if the value was set to
+ * non-NULL.

-Building and installing jemalloc can be as simple as typing the following while
-in the root directory of the source tree:
-
-    ./configure
-    make
-    make install
-
-=== Advanced configuration =====================================================
-
-The 'configure' script supports numerous options that allow control of which
-functionality is enabled, where jemalloc is installed, etc.  Optionally, pass
-any of the following arguments (not a definitive list) to 'configure':
-
---help
-    Print a definitive list of options.
-
---prefix=<install-root-dir>
-    Set the base directory in which to install.  For example:
-
-        ./configure --prefix=/usr/local
-
-    will cause files to be installed into /usr/local/include, /usr/local/lib,
-    and /usr/local/man.
-
---with-rpath=<colon-separated-rpath>
-    Embed one or more library paths, so that libjemalloc can find the libraries
-    it is linked to.  This works only on ELF-based systems.
-
---with-jemalloc-prefix=<prefix>
-    Prefix all public APIs with <prefix>, so that, for example, malloc()
-    becomes <prefix>malloc().  This makes it possible to use jemalloc at the
-    same time as the system allocator.
-
---with-install-suffix=<suffix>
-    Append <suffix> to the base name of all installed files, such that multiple
-    versions of jemalloc can coexist in the same installation directory.  For
-    example, libjemalloc.so.0 becomes libjemalloc<suffix>.so.0.
-
---enable-debug
-    Enable assertions and validation code.  This incurs a substantial
-    performance hit, but is very useful during application development.
-
---enable-stats
-    Enable statistics gathering functionality.  Use the 'P' option to print
-    detailed allocation statistics at exit.
-
---enable-prof
-    Enable heap profiling and leak detection functionality.  Use the 'B', 'E',
-    'F', 'I', 'L', and 'U' options to control these features.
-
---disable-prof-libgcc
-    Disable the use of libgcc's backtracing functionality.  Ordinarily, libgcc's
-    backtracing functionality is superior to the alternatives, but it may fail
-    to capture backtraces on some systems.
-
---enable-prof-libunwind
-    Use the libunwind library (http://www.nongnu.org/libunwind/) for stack
-    backtracing.  libunwind is quite slow, but it tends to work across a wider
-    variety of system configurations than the default backtracing code, which is
-    based on libgcc functionality or gcc intrinsics.
-
---with-static-libunwind=<libunwind.a>
-    Statically link against the specified libunwind.a rather than dynamically
-    linking with -lunwind.
-
---disable-tiny
-    Disable tiny (sub-quantum-sized) object support.  Technically it is not
-    legal for a malloc implementation to allocate objects with less than
-    quantum alignment (8 or 16 bytes, depending on architecture), but in
-    practice it never causes any problems if, for example, 4-byte allocations
-    are 4-byte-aligned.
-
---disable-tcache
-    Disable thread-specific caches for small objects.  Objects are cached and
-    released in bulk, thus reducing the total number of mutex operations.  Use
-    the 'H', 'G', and 'M' options to control thread-specific caching.
-
---enable-swap
-    Enable mmap()ed swap file support.  When this feature is built in, it is
-    possible to specify one or more files that act as backing store.  This
-    effectively allows for per application swap files.
-
---enable-dss
-    Enable support for page allocation/deallocation via sbrk(2), in addition to
-    mmap(2).
-
---enable-fill
-    Enable support for junk/zero filling of memory.  Use the 'J' option to
-    control junk filling, or the 'Z' option to control zero filling.
-
---enable-xmalloc
-    Enable support for optional immediate termination due to out-of-memory
-    errors, as is commonly implemented by "xmalloc" wrapper function for malloc.
-    Use the 'X' option to control termination behavior.
-
---enable-sysv
-    Enable support for System V semantics, wherein malloc(0) returns NULL
-    rather than a minimal allocation.  Use the 'V' option to control System V
-    compatibility.
-
---enable-dynamic-page-shift
-    Under most conditions, the system page size never changes (usually 4KiB or
-    8KiB, depending on architecture and configuration), and unless this option
-    is enabled, jemalloc assumes that page size can safely be determined during
-    configuration and hard-coded.  Enabling dynamic page size determination has
-    a measurable impact on performance, since the compiler is forced to load
-    the page size from memory rather than embedding immediate values.
-
---disable-lazy-lock
-    Disable code that wraps pthread_create() to detect when an application
-    switches from single-threaded to multi-threaded mode, so that it can avoid
-    mutex locking/unlocking operations while in single-threaded mode.  In
-    practice, this feature usually has little impact on performance unless
-    thread-specific caching is disabled.
-
---disable-tls
-    Disable thread-local storage (TLS), which allows for fast access to
-    thread-local variables via the __thread keyword.  If TLS is available,
-    jemalloc uses it for several purposes.  Note that disabling TLS implies
-    --disable-tcache.
-
-The following environment variables (not a definitive list) impact configure's
-behavior:
-
-CFLAGS="?"
-    Pass these flags to the compiler.  You probably shouldn't define this unless
-    you know what you are doing.  (Use EXTRA_CFLAGS instead.)
-
-EXTRA_CFLAGS="?"
-    Append these flags to CFLAGS.  This makes it possible to add flags such as
-    -Werror, while allowing the configure script to determine what other flags
-    are appropriate for the specified configuration.
-
-    The configure script specifically checks whether an optimization flag (-O*)
-    is specified in EXTRA_CFLAGS, and refrains from specifying an optimization
-    level if it finds that one has already been specified.
-
-CPPFLAGS="?"
-    Pass these flags to the C preprocessor.  Note that CFLAGS is not passed to
-    'cpp' when 'configure' is looking for include files, so you must use
-    CPPFLAGS instead if you need to help 'configure' find header files.
-
-LD_LIBRARY_PATH="?"
-    'ld' uses this colon-separated list to find libraries.
-
-LDFLAGS="?"
-    Pass these flags when linking.
-
-PATH="?"
-    'configure' uses this to find programs.
-
-=== Advanced compilation =======================================================
-
-To install only parts of jemalloc, use the following targets:
-
-    install_bin
-    install_include
-    install_lib
-    install_man
-
-To clean up build results to varying degrees, use the following make targets:
-
-    clean
-    distclean
-    relclean
-
-=== Advanced installation ======================================================
-
-Optionally, define make variables when invoking make, including (not
-exclusively):
-
-INCLUDEDIR="?"
-    Use this as the installation prefix for header files.
-
-LIBDIR="?"
-    Use this as the installation prefix for libraries.
-
-MANDIR="?"
-    Use this as the installation prefix for man pages.
-
-DESTDIR="?"
-    Prepend DESTDIR to INCLUDEDIR, LIBDIR, and MANDIR.  This is useful when
-    installing to a different path than was specified via --prefix.
-
-CC="?"
-    Use this to invoke the C compiler.
-
-CFLAGS="?"
-    Pass these flags to the compiler.
-
-CPPFLAGS="?"
-    Pass these flags to the C preprocessor.
-
-LDFLAGS="?"
-    Pass these flags when linking.
-
-PATH="?"
-    Use this to search for programs used during configuration and building.
-
-=== Development ================================================================
-
-If you intend to make non-trivial changes to jemalloc, use the 'autogen.sh'
-script rather than 'configure'.  This re-generates 'configure', enables
-configuration dependency rules, and enables re-generation of automatically
-generated source files.
-
-The build system supports using an object directory separate from the source
-tree.  For example, you can create an 'obj' directory, and from within that
-directory, issue configuration and build commands:
-
-    autoconf
-    mkdir obj
-    cd obj
-    ../configure --enable-autogen
-    make

-jemalloc is a general-purpose scalable concurrent malloc(3) implementation.
-This distribution is a stand-alone "portable" implementation that currently
-targets only Linux.  jemalloc is included as the default allocator in the
-FreeBSD and NetBSD operating systems, and it is used by the Mozilla Firefox web
-browser on Microsoft Windows-related platforms.  Depending on your needs, one
-of the other divergent versions may suit your needs better than this
-distribution.
-
-The COPYING file contains copyright and licensing information.
-
-The INSTALL file contains information on how to configure, build, and install
-jemalloc.
