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.
clang-cl: Include /FI headers in /showIncludes output. -H in gcc mode doesn't print -include headers, but they are included in depfiles written by MMD and friends. Since /showIncludes is what's used instead of depfiles, printing /FI there seems important (and matches cl.exe). Instead of giving HeaderIncludeGen more options, just switch on ShowAllHeaders in clang-cl mode and let clang::InitializePreprocessor() not put -include flags in the <command line> block. This changes the behavior of -E slightly, and it removes the <command line> flag from the output triggered by setting the obscure CC_PRINT_HEADERS=1 env var to true while running clang. Both of these seem ok to change. http://reviews.llvm.org/D18401 llvm-svn: 264174
