| 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 |
