/* This file enumerates variables from the MLIR configuration so that they
   can be in exported headers and won't override package specific directives.
   Defining the variables here is preferable over specifying them in CMake files
   via `target_compile_definitions` because it is easier to ensure that they are
   defined consistently across all targets: They are guaranteed to be 0/1
   variables thanks to #cmakedefine01, so we can test with `#if` and find
   missing definitions or includes with `-Wundef`. With `#ifdef`, these mistakes
   can go unnoticed.

   This is a C header that can be included in the mlir-c headers. */
