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
