It is processed by the autoconf 9dnl program to produce a script named configure.

As this file evolves, 13dnl please keep the various types of checks within their sections. The sections 14dnl are as follows: 15dnl 16dnl SECTION 1: Initialization & Setup 17dnl SECTION 2: Architecture, target, and host checks 18dnl SECTION 3: Command line arguments for the configure script. 19dnl SECTION 4: Check for programs we need and that they are the right version 20dnl SECTION 5: Check for libraries 21dnl SECTION 6: Check for header files 22dnl SECTION 7: Check for types and structures 23dnl SECTION 8: Check for specific functions needed 24dnl SECTION 9: Additional checks, variables, etc. 25dnl SECTION 10: Specify the output files and generate it 26dnl 27dnl===-----------------------------------------------------------------------=== 28dnl=== 29dnl=== SECTION 1: Initialization & Setup 30dnl=== 31dnl===-----------------------------------------------------------------------=== 32dnl Initialize autoconf and define the package name, version number and 33dnl address for reporting bugs. 34AC_INIT([LLVM],[3.2svn],[http://llvm.org/bugs/]) 35AC_DEFINE([LLVM_VERSION_MAJOR], [3], [Major version of the LLVM API]) 36AC_DEFINE([LLVM_VERSION_MINOR], [2], [Minor version of the LLVM API]) 37 38dnl Provide a copyright substitution and ensure the copyright notice is included 39dnl in the output of --version option of the generated configure script. 40AC_SUBST(LLVM_COPYRIGHT,["Copyright (c) 2003-2012 University of Illinois at Urbana-Champaign."]) 41AC_COPYRIGHT([Copyright (c) 2003-2012 University of Illinois at Urbana-Champaign.]) 42 43dnl Indicate that we require autoconf 2.60 or later. 44AC_PREREQ(2.60) 45 46dnl Verify that the source directory is valid.
