clang-cl: Add a test for the interaction of /Yc and /showIncludes. We almost get this right, but not completely (see FIXME). It looks like /FI headers generally aren't included in /showIncludes yet, but they should be. But it seems good to have test coverage for the bits that already work. llvm-svn: 263344

// Note: %s and %S must be preceded by --, otherwise it may be interpreted as a
// command-line option, e.g. on Mac where %s is commonly under /Users.
// Tests interaction of /Yc / /Yu with /showIncludes
#include "header3.h"
// When building the pch, header1.h (included by header2.h), header2.h (the pch
// input itself) and header3.h (included directly, above) should be printed.
// RUN: %clang_cl -Werror /showIncludes /I%S/Inputs /Ycheader2.h /FIheader2.h /Fp%t.pch /c -- %s 2>&1 \
// RUN: | FileCheck -check-prefix=CHECK-YC %s
clang-cl: Add /Yc argument to /showIncludes output. To make this work, delay printing of ExtraDeps in HeaderIncludesCallback a bit, so that it happens after CompilerInstance::InitializeSourceManager() has run. General /FI arguments are still missing from /showIncludes output, this still needs to be fixed. llvm-svn: 263352
