URL: https://github.com/llvm/llvm-project/commit/c6f8704053ba364cf8cc9a0a966617efeda079f7 DIFF: https://github.com/llvm/llvm-project/commit/c6f8704053ba364cf8cc9a0a966617efeda079f7.diff LOG: [clang][deps] Disable global module index While scanning dependencies of a TU that depends on a PCH, the scanner basically performs mixed implicit/explicit modular compilation. (Explicit modules come from the PCH.) This seems to trip up the global module index. This patch disables global module index in the dependency scanner.
