Prior to this patch, we would generate a fancy <__config> header by concatenating <__config_site> and <__config>. This complexifies the build system and also increases the difference between what's tested and what's actually installed. This patch removes that complexity and instead simply installs <__config_site> alongside the libc++ headers. <__config_site> is then included by <__config>, which is much simpler. Doing this also opens the door to having different <__config_site> headers depending on the target, which was impossible before. It does change the workflow for testing header-only changes to libc++. Previously, we would run `lit` against the headers in libcxx/include. After this patch, we run it against a fake installation root of the headers (containing a proper <__config_site> header). This makes use closer to testing what we actually install, which is good, however it does mean that we have to update that root before testing header changes. Thus, we now need to run `ninja check-cxx-deps` before running `lit` by hand. Differential Revision: https://reviews.llvm.org/D97572 |
