      Toolchain support · 0c1ba2e6
      Drew authored
      This allows atbuild to use a different toolchain other than the one we
      use to develop atbuild (weekly snapshot).
      In particular, this allows you to use "released swift" "xcode swift" or
      any other kind of 2.2 Swift.
      Documentation PR to follow.
      Edited README to discuss atbuild options.
      Resolves #58 to my satisfaction.

      Allow variable expansion for shell tool · 409cc69b
      Drew authored
      This allows the execution of a shell tool with the "collected sources"
      of another task.
      The intent here is to allow the creation of arbitrary tasks that accept
      source files as arguments. xcode-emit is an obvious candidate, and
      would allow it to break its dependence on atpkg, which it only uses for
      this single feature.
      There are other obvious programs that we might want to call with "all
      sources" (e.g. preprocessors, etc.) and they may not want to take a
      dependency on atpkg either.
      See https://github.com/AnarchyTools/atpkg/pull/23

      Support whole-module-optimization · eadeb144
      Drew authored
      Due to SR-881, whole-module-optimization is more complicated than simply
      adding it to compile options.
      As a workaround, we compile twice.

      Mute warnings · b8374eb6
      Drew authored
      Update for atpkg:mute_warnings, which changes the package constructor
      We silence certain redundant warnings that are probably useless.

      Ignore tool keys when warning from atllbuild · 6c86e64e
      Drew authored
      Previously, atllbuild would emit some spurious warnings when a tool key
      was used such as `overlays`.  We now ignore all tool keys.

      Umbrella headers v2 · 587894a9
      Drew authored
      We now include the synthesized module map in our build products.  To
      support this, a new `:modulemap "synthesized"` directive is available
      (and must be used if `umbrella-header` is used.)  We could potentially
      have other modulemap modes besides synthesized (explicit, for example).
      We use one modulemap privately as part of the build process (to store
      the umbrella header) and a different one publicly (which doesn't have
      the umbrella header).
      This is (surprisingly!) totally legal under the Clang module map
      > However, in some cases, the presence or absence of particular headers is used to distinguish between the “public” and “private” APIs of a particular library. For example, a library may contain the headers Foo.h and Foo_Private.h, providing public and private APIs, respectively. Additionally, Foo_Private.h may only be available on some versions of library, and absent in others. One cannot easily express this with a single module map file in the library:
      module Foo {
        header "Foo.h"
        explicit module Private {
          header "Foo_Private.h"
      > because the header Foo_Private.h won’t always be available. The module
      > map file could be customized based on whether Foo_Private.h is
      > available or not, but doing so requires custom build machinery.
      We are the custom build machinery of which the clattner foretold.
      Note that (some) Swift engineers claim this is dangerous, but it works,
      is compliant with the Clang specification, and the tests pass.
      I should probably also document one other thing that I found diagnosing
      why the previous approach didn't work.  A "swiftmodule" (which nobody
      seems to understand) actually (sometimes) functions as an overlay for a
      Clang module.  See e.g.
      What happen is that if you compile with -import-underlying-module (which
      we do in the umbrella case) the swift module that gets built is a
      "overlay" that points to some underlying clang module, see here:
      https://twitter.com/drewcrawford/status/694995772148846592.  Then at
      import time somebody goes looking for that underlying module (e.g.
      modulemap) in addition to the .swiftmodule.
      However there is no reason (as far as Clang is concerned) why the
      modulemap it finds at runtime may not be totally different than the
      modulemap we used at compile time, so that's what we do.

      Add `umbrella-header` to specify umbrella headers · 089ebe8b
      Drew authored
      This is essentially the same as a "bridging" header, except without any
      ObjC (straight C).  Upstream says it "can't be done"; let's see if Linux
      CI likes this implementation.  Take *that*, anonymous compiler engineers.
      My motivation for this patch is essentially as a workaround for SR-655.
      That is to say, I want to call some arbitrary C code, but due to that
      bug, I can't hide my C code behind a module / modulemap.
      Instead what I can do is just `#include <whatever>` in my umbrella
      header, and then the C imports are available to Swift.
      Internally, we emit a modulemap based on the umbrella header and then
      inject some compile flags (notably, `-import-underlying-module`) to make
      it load.  This is the design I reverse-engineered from Xcode.  That
      notwithstanding, it seems to be based entirely on public APIs and I
      guess we'll find out if it works on Linux.
      While my motivation is based on C imports, umbrella headers may be
      useful wherever Swift projects are sold.  There are multiple features
      that get unlocked here, including access to the C preprocessor.

      Make the "passed successfully" text green. · 0c61b897
      Drew authored
      Our swiftc frontend is typically colored, which draws attention to
      various (expected) compile failures in our test suite.
      To fix this, our test suite pass should report green and bold, so I stop
      debugging test failures that aren't failures at all.

      Add `publishProduct` atllbuild option · 0b8b3339
      Drew authored
      This allows a build.atpkg to export its products into a user-visible directory.
      I'm not totally sure this is the right design, but it does resolve #17.
