We think that the libdispatch incremental rebuilds didn't know that if swiftc changed it needed to invalidate the compilation of the swift dispatch overlay files (missing dependency in the make rule). A localized change that could be enough to fix the problem is libdispatch PR #178. If that isn't enough, we might have to do a more ambitious restructuring of the libdispatch build.

Oh, I didn’t realize we had a separate copy of the overlay code (almost
certainly the right thing to do at this point). But in that case, why are
we seeing any of these errors?

The order may need to vary by platform. On Linux, the DIspatch Swift
overlay code lives in swift-corelibs-libdispatch/src/swift. So it
works to build (1) Swift (2) libdispatch (both C and Swift) (3)
Foundation.

I think the right order to build things is:
1. libdispatch (C)
2. Swift (compiler + stdlib + Dispatch overlay)
3. Foundation
Otherwise we need to build Swift, then build libdispatch, then go
back to "Swift" to build the overlay, and only finally get to
Foundation.

I don’t know how these dependencies are expressed in
CMake but it doesn’t seem very difficult to do so in the
autotools buildsystem, we have
AC_ARG_WITH([swift-toolchain],
[AS_HELP_STRING([--with-swift-toolchain], [Specify path
to Swift toolchain])],
[swift_toolchain_path=${withval}
AC_DEFINE(HAVE_SWIFT, 1, [Define if building for Swift])
SWIFTC="$swift_toolchain_path/bin/swiftc”
in configure.ac which ends up as a SWIFTC makefile
variable, so as long as that argument is passed as an
absolute path, it should work as a dependency in the
build rules
$(abs_builddir)/swift/%.o: $(abs_srcdir)/swift/%.swift
$(SWIFTC) -frontend -c $(SWIFT_ABS_SRC_FILES)
-primary-file $< \
Is there a JIRA ticket for this ? the IBM folks should
probably be the ones making these changes since we still
don’t have the whitelist in place for Apple contributors
to do so…

There
isn’t a
dependency
in the Dispatch project to tell it is building with a new compiler. The
project
would
need to
be
modified
to add a
dependency
on the swiftc binary being used to compile this project.
