-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
