'configure' configures Valgrind 3.27.0.RC1 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]
  --runstatedir=DIR       modifiable per-process data [LOCALSTATEDIR/run]
  --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]
  --infodir=DIR           info documentation [DATAROOTDIR/info]
  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
  --mandir=DIR            man documentation [DATAROOTDIR/man]
  --docdir=DIR            documentation root [DATAROOTDIR/doc/valgrind]
  --htmldir=DIR           html documentation [DOCDIR]
  --dvidir=DIR            dvi documentation [DOCDIR]

                          do not reject slow dependency extractors
  --disable-dependency-tracking
                          speeds up one-time build
  --enable-only64bit      do a 64-bit only build
  --enable-only32bit      do a 32-bit only build
  --enable-inner          enables self-hosting

  --enable-lto          enables building with link time optimisation
  --enable-tls            platform supports TLS

Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-darwin-platform=PLAT  Specify which Darwin platform we are compiling for (macOS, iOS, etc)

# VGCONF_ARCH_PRI is the arch for the primary build target, eg. "amd64".  By

# machine, but --enable-only32bit has been requested, then ARCH_MAX (see
# above) will be "amd64" since that reflects the most that this cpu can do,
# but VGCONF_ARCH_PRI will be downgraded to "x86", since that reflects the
# arch corresponding to the primary build (VGCONF_PLATFORM_PRI_CAPS).  It is
# passed in to compilation of many C files via -VGA_$(VGCONF_ARCH_PRI) and
# -VGP_$(VGCONF_ARCH_PRI)_$(VGCONF_OS).


# VGCONF_ARCH_SEC is the arch for the secondary build target, eg. "x86".
# It is passed in to compilation of many C files via -VGA_$(VGCONF_ARCH_SEC)
# and -VGP_$(VGCONF_ARCH_SEC)_$(VGCONF_OS), if there is a secondary target.
# It is empty if there is no secondary target.


# VGCONF_PLATFORM_PRI_CAPS is the primary build target, eg. "AMD64_LINUX".
# The entire system, including regression and performance tests, will be
# built for this target.  The "_CAPS" indicates that the name is in capital
# letters, and it also uses '_' rather than '-' as a separator, because it's
# used to create various Makefile variables, which are all in caps by
# convention and cannot contain '-' characters.  This is in contrast to
# VGCONF_ARCH_PRI and VGCONF_OS which are not in caps.


# VGCONF_PLATFORM_SEC_CAPS is the secondary build target, if there is one.
# Valgrind and tools will also be built for this target, but not the
# regression or performance tests.
#
# By default, the primary arch is the same as the "max" arch, as commented
# above (at the definition of ARCH_MAX).  We may choose to downgrade it in
# the big case statement just below here, in the case where we're building
# on a 64 bit machine but have been requested only to do a 32 bit build.

# Platform variants?
#----------------------------------------------------------------------------

# Normally the PLAT = (ARCH, OS) characterisation of the platform is enough.
# But there are times where we need a bit more control.  The motivating
# and currently only case is Android: this is almost identical to
# {x86,arm,mips}-linux, but not quite.  So this introduces the concept of
# platform variant tags, which get passed in the compile as
# -DVGPV_<arch>_<os>_<variant> along with the main -DVGP_<arch>_<os> definition.
#
# In almost all cases, the <variant> bit is "vanilla".  But for Android
# it is "android" instead.
#
# Consequently (eg), plain arm-linux would build with
#
#   -DVGP_arm_linux -DVGPV_arm_linux_vanilla
#
# whilst an Android build would have
#
#   -DVGP_arm_linux -DVGPV_arm_linux_android
#
# Same for x86. The setup of the platform variant is pushed relatively far
# down this file in order that we can inspect any of the variables set above.

# In the normal case ..

# VGCONF_PLATFORMS_INCLUDE and VGCONF_OS_IS above?  Could easily enough
# do that.  Problem is that we can't do and-ing in Makefile.am's, but
# that's what we'd need to do to use this, since what we'd want to write

# that checking is done against the warning flag itself, but the
# substitution is then done to cancel the warning flag.


# Convenience function. Like AC_GCC_WARNING_SUBST_NO, except it substitutes
# -W$1  (instead of -Wno-$1).

# We want to use use the -Ttext-segment option to the linker.
# GNU (bfd) ld supports this directly. Newer GNU gold linkers
# support it as an alias of -Ttext. Sadly GNU (bfd) ld's -Ttext
# semantics are NOT what we want (GNU gold -Ttext is fine).
#
# For GNU (bfd) ld -Ttext-segment chooses the base at which ELF headers
# will reside. -Ttext aligns just the .text section start (but not any
# other section).
#
# LLVM ld.lld 10.0 changed the semantics of its -Ttext. See "Breaking changes"
# in https://releases.llvm.org/10.0.0/tools/lld/docs/ReleaseNotes.html
# The --image-base option (since version 6.0?) provides the semantics needed.
# -Ttext-segment generates an error, but -Ttext now more closely
# follows the GNU (bfd) ld's -Ttext.
#
# So test first for --image-base support, and if that fails then
# for -Ttext-segment which is supported by all bfd ld versions
# and use that if it exists. If it doesn't exist it must be an older
# version of gold and we can fall back to using -Ttext which has the
# right semantics.

/* Thanks to Mike Haertel and Jim Avera for this test.
   Here is a matrix of mmap possibilities:
	mmap private not fixed
	mmap private fixed at somewhere currently unmapped
	mmap private fixed at somewhere already mapped
	mmap shared not fixed
	mmap shared fixed at somewhere currently unmapped
	mmap shared fixed at somewhere already mapped
   For private mappings, we should verify that changes cannot be read()
   back from the file, nor mmap's back from the file at a different
   address.  (There have been systems where private was not correctly
   implemented like the infamous i386 svr4.0, and systems where the
   VM page cache was not coherent with the file system buffer cache
   like early versions of FreeBSD and possibly contemporary NetBSD.)
   For shared mappings, we should conversely verify that changes get
   propagated back to all the places they're supposed to be.  */

# tests are present because Drd has some regression tests that use
# these packages.  All regression test programs all compiled only
# for the primary target.  And so it is important that the configure
# checks that follow, use the correct -m32 or -m64 flag for the
# primary target (called $mflag_primary).  Otherwise, we can end up
# in a situation (eg) where, on amd64-linux, the test for Boost checks
# for usable 64-bit Boost facilities, but because we are doing a 32-bit
# only build (meaning, the primary target is x86-linux), the build
# of the regtest programs that use Boost fails, because they are
# build as 32-bit (IN THIS EXAMPLE).
#
# Hence: ALWAYS USE $mflag_primary FOR CONFIGURE TESTS FOR FACILITIES
# NEEDED BY THE REGRESSION TEST PROGRAMS.


# Check whether the boost library 1.35 or later has been installed.
# The Boost.Threads library has undergone a major rewrite in version 1.35.0.

# It is not useful on other systems.  If it contains results you don't
# want to keep, you may remove or edit it.

# but we know of no workaround that is simple, portable, and efficient.
# So, we kill variables containing newlines.
# Ultrix sh set writes to stderr and can't be redirected directly,
# and sets the high bit in the cache file unless we assign to the vars.
