   1 // This is a regression test for handling of stat caches within the tooling
   2 // infrastructure. This test reproduces the problem under valgrind:
   3
   4 // First, create a pch that we can later load. Loading the pch will insert
   5 // a stat cache into the FileManager:
   6 // RUN: %clang -x c++-header %S/Inputs/pch.h -o %t1
   7
   8 // Use the generated pch and enforce a subsequent stat miss by using
   9 // the test file with an unrelated include as second translation unit.
  10 // Test for an non-empty file after clang-check is executed.
  11 // RUN: clang-check -ast-dump "%S/Inputs/pch.cpp" "%s" -- -include-pch %t1 -I "%S" -c >%t2 2>&1
  12 // RUN: test -s %t2
