This feels wrong. I don't think that we should be trying to format with indentation here. Do any other warnings try to do this?

I thought it read better, but had not finalized it yet. I will look at the other warnings next and match them.

Wait, why are we not preferring -sdk paths?

Once the Frontend change is made for non-Darwin, the RuntimeResourcePath in the very next block has been set to <-sdk>/usr/lib/swift, so this explicit getSDKPath() check is not needed when targeting non-Darwin. 😺

This code explicitly follows what the original C++ Driver has long done when looking for the Swift runtime libraries, swiftrt.o, and a few other files found in the Swift resource directory:

if (const Arg *A = args.getLastArg(options::OPT_resource_dir)) {
    StringRef value = A->getValue();
    resourceDirPath.append(value.begin(), value.end());
  } else if (!getTriple().isOSDarwin() && args.hasArg(options::OPT_sdk)) {
    StringRef value = args.getLastArg(options::OPT_sdk)->getValue();
    resourceDirPath.append(value.begin(), value.end());
    llvm::sys::path::append(resourceDirPath, "usr");
    CompilerInvocation::appendSwiftLibDir(resourceDirPath, shared);
  } else {
    auto programPath = getDriver().getSwiftProgramPath();
    CompilerInvocation::computeRuntimeResourcePathFromExecutablePath(
        programPath, shared, resourceDirPath);
  }

Note how the SDK is only looked in if a non-Darwin -sdk is explicitly specified: Saleem later tried to expand that to Darwin also in #26361, but he may have never got it to work.

That C++ Driver setup now matches this Frontend setup, because the default in both is now to look relative to the compiler, which is done first in this Frontend here, ie usr/bin/../lib/swift/. If a -resource-dir is set, that is given first priority, then a non-Darwin -sdk is given second priority, ie the C++ Driver and the Frontend now match in where they look.

This is important for two reasons:

  1. The new swift-driver simply queries the Frontend and uses whatever Swift resource directory it uses, so now the new swift-driver finally matches the original C++ Driver's behavior, and piecemeal workarounds like that in [Unix] Go back to only checking the runtime resource path for swiftrt.o swift-driver#1822 can now be eliminated.
  2. The Frontend will now look in the same Swift resource directory for stdlib/corelibs swiftmodules as the swift-driver is looking for runtime libraries and swiftrt.o, eliminating any confusion between the two by centralizing the Swift resource directory lookup here. That already found one bug in the Windows CI, see my other code comment.

However, unlike the C++ Driver, my -sdk code below actually checks if the -sdk path contains a Swift resource directory for the platform triple and does not use the -sdk for this if not, falling back to the aforementioned default next to the compiler in that case. This is because an -sdk is not guaranteed to have a Swift resource directory and may have only a C/C++ sysroot.

We should probably tighten this up to require an explicit -sdk to have a Swift resource directory, with the only exception when an explicit -resource-dir is also specified, but I'm open to debate here. The C++ Driver doesn't even check if the non-Darwin -sdk has a Swift resource directory and simply assumes one is there, we can do a bit better than that.

SDKResourcePath, "usr", "lib",

Opts.RuntimeResourcePath = SDKResourcePath.str();
else

Opts.RuntimeResourcePath);
}
