clang-cl: add the /c, /W0 and /W1 options This adds a few more clang-cl options. It also exposes two core clang options to the clang-cl mode: we need to be able to claim --driver_mode so it doesn't show up as unused in cl mode, and we need -### for tests.

clang-cl: ignore compile-only options in link-only invocations. Previously we would warn about unused arguments such as /MD when linking. Clang already has logic to ignore compile-only options, e.g. for -D and -U. This patch extends that to include clang-cl's compile-only options too. Also, some clang-cl options should always be ignored. Doing this earlier means they get ignored both for compilation and link-only invocations. llvm-svn: 190825

Try to fix the cl-options.c test on ARM bots The test was failing because clang-cl changes the default triple to target MSVC-style Win32. This is kind of wonky, but hasn't been a problem until we started warning: warning: unknown platform, assuming -mfloat-abi=soft Some of the tests in cl-options.c were running with -Werror, causing them to fail. Fixing this by FileCheck-ifying those tests instead of using -Werror. llvm-svn: 205049

Re-commit r187637: "clang-cl: add more options" > This adds a bunch of options to clang-cl. Notably, this includes > all the options that get passed when doing a default build of a > command-line project with msbuild.exe in Debug and Release modes, > and I believe all flags from Reid's original patch. The original commit was reverted in r187640 after it broke the Mac build. This should now be fixed, by Clang r187668, LLVM r187675, and putting a -- before %s in the test. llvm-svn: 187679

clang-cl: Make the driver parse all(?) msvc flags Even if we don't support a flag, we should be able to parse it to provide a better error message than the current default "error: no such file or directory: '/foo'" (which we should probably also tweak, btw). This also tries to clean up the test file a bit. llvm-svn: 194837

Driver: Handle /GR- in a compatible way with MSVC There are slight differences between /GR- and -fno-rtti which made mapping one to the other inappropriate. -fno-rtti disables dynamic_cast, typeid, and does not emit RTTI related information for the v-table. /GR- does not generate complete object locators and thus will not reference them in vftables. However, constructs like dynamic_cast and typeid are permitted. This should bring our implementation of RTTI up to semantic parity with MSVC modulo bugs. llvm-svn: 212138
