dnl This is the LLVM configuration script. It is processed by the autoconf
dnl program to produce a script named configure. This script contains the
dnl configuration checks that LLVM needs in order to support multiple platforms.
dnl This file is composed of 10 sections per the recommended organization of
dnl autoconf input defined in the autoconf documentation. As this file evolves,
dnl please keep the various types of checks within their sections. The sections
dnl are as follows:
dnl
dnl SECTION 1: Initialization & Setup
dnl SECTION 2: Architecture, target, and host checks
dnl SECTION 3: Command line arguments for the configure script.
dnl SECTION 4: Check for programs we need and that they are the right version
dnl SECTION 5: Check for libraries
dnl SECTION 6: Check for header files
dnl SECTION 7: Check for types and structures
dnl SECTION 8: Check for specific functions needed
dnl SECTION 9: Additional checks, variables, etc.
dnl SECTION 10: Specify the output files and generate it
