[CMake] Providing a CMake cache for 3-stage builds<br class="">
<br class="">
This cache file can be used to generate a 3-stage clang build. You can configure using the following CMake command:<br class="">
<br class="">
cmake -C <path to clang>/cmake/caches/3-stage.cmake -G Ninja <path to llvm><br class="">
<br class="">
You can then run "ninja stage3-clang" to build stage1, stage2 and stage3 clangs.<br class="">
<br class="">
This is useful for finding non-determinism the compiler by verifying that stage2 and stage3 are identical.<br class="">
