// Check that the scanner produces raw ast files, even when builds produce the
// obj format, and that the scanner can read obj format from PCH and modules
// imported by PCH.

// Unsupported on AIX because we don't support the requisite "__clangast"
// section in XCOFF yet.
// UNSUPPORTED: target={{.*}}-aix{{.*}}

// REQUIRES: shell

// RUN: rm -rf %t && mkdir %t
// RUN: cp %S/Inputs/modules-pch/* %t

// Scan dependencies of the PCH:
