Consider: 1) Generate PCH with -fmodules and -fmodule-map-file 2) Use PCH with -fmodules and the same -fmodule-map-file If we don't load -fmodule-map-file content before including PCHs, the modules that are dependencies in PCHs cannot get loaded, since there's no matching module map file when reading back the AST. rdar://problem/40852867 Differential Revision: https://reviews.llvm.org/D48685 llvm-svn: 337447
