Reapply r11184 with fixes for makefile builds.
Use CodeGenABITypes to determine which return values should be indirect
in @objc methods.
Swift SVN r11226
This works around <rdar://problem/15639860>, which covers properly handling a missing -sdk argument at either the driver or frontend level (or at both levels).
Swift SVN r11153
- Added support for invoking the Swift frontend via "swift_driver -frontend".
- Added frontend_main.cpp, which implements the main entry point for the
integrated frontend. (Currently, this supports compiling an input Swift file
into an object file.)
- Removed lib/Frontend/FrontendOptions.td, and replaced its functionality with
options in include/Swift/Driver/Options.td and a new
include/Swift/Driver/FrontendOptions.td. Options supported by the frontend
are denoted by the FrontendOption flag; options which are not supported by
the driver are denoted by the NoDriverOption flag.
- Updated CompilerInvocation::parseArgs() to use the option table returned from
createDriverOptTable(), including renaming a handful of options. (-triple is
now -target, and -Xclang is now -Xcc.)
Swift SVN r11082
- Added a couple of new targets:
- libswiftDriver, which contains most of the driver implementation
- swift_driver, which produces the actual executable
- Added centralized version information into libswiftBasic.
- Added a new "Driver Design & Internals" document, which currently describes
the high-level design of the Swift driver.
- Implemented an early version of the functionality of the driver, including
versions of the Parse, Pipeline, Bind, Translate, and Execute driver stages.
Parse, Pipeline, and Bind are largely implemented; Translate and Execute are
early placeholders. (Translate produces "swift_driver --version" and "ld -v"
commands, while Execute performs all subtasks sequentially, rather than in
parallel.)
This is just the starting point for the Swift driver. Tests for the existing
behavior are forthcoming.
