rG26311f00e860: Remove autotools build system
rPLO259041: Remove autotools build system
rL259041: Remove autotools build system

Summary

The autotools build system is based on and requires LLVM's autotools build system to work, which has been removed in r258861. Subsequently we also remove the autotools build system from Polly.

	\`configure' configures Polly 0.01 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]
	--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/polly]
	--htmldir=DIR html documentation [DOCDIR]

	--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
	--enable-polly-gpu-codegen
	Enable GPU code generation in Polly(default is NO)

	Optional Packages:
	--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
	--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
	--with-llvmsrc Location of LLVM Source Code
	--with-llvmobj Location of LLVM Object Code
	--with-cuda prefix of cuda

	Some influential environment variables:
	CXX C++ compiler command
	CXXFLAGS 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 (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
	you have headers in a nonstandard directory <include dir>

	Use these variables to override the choices made by `configure' or to help
	it to find libraries and programs with nonstandard names/locations.
