With clang-cl, when the user specifies /Yc or /Yu without a filename the compiler uses a #pragma hdrstop in the main source file to determine the end of the PCH. If a header is specified with /Yc or /Yu #pragma hdrstop has no effect. The optional #pragma hdrstop filename argument is not yet supported.
