Since a Job may be reached through multiple paths in the dependency graph, we
need to include support for caching Jobs. (Currently, the cache maps
Action/ToolChain pairs to Jobs.)
As a result of these changes, Tool::constructJob() and
Driver::buildJobsForAction() return a plain Job *, instead of a
std::unique_ptr<Job>, since the Jobs returned by buildJobsForAction() no longer
need to be unique.

Added driver-level support for generating commands with -emit-ir and -emit-bc as well integrated frontend support for handling -emit-ir and -emit-bc.

In Driver::translateInputArgs(), don’t break apart the OPT__DASH_DASH argument if we’re in immediate mode.
Mark OPT__DASH_DASH as being a FrontendOption.
In Swift::constructJob(), add support for types::TY_Nothing, and pass the argument for OPT__DASH_DASH as-is if the driver is invoking the frontend in immediate mode.
Swift SVN r11325
- 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
Instead of producing "swift_driver --version" commands, implemented support for producing
"swift" commands which actually compile code. (The support at this point is rudimentary,
but serves as a good starting point.)
Swift SVN r10949
- 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.
