8dnl This is the LLVM configuration script. It is processed by the autoconf
9dnl program to produce a script named configure. This script contains the
10dnl configuration checks that LLVM needs in order to support multiple platforms.
11dnl This file is composed of 10 sections per the recommended organization of
12dnl autoconf input defined in the autoconf documentation. 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
