This sets OutputInfo::CompilerMode to a new SingleCompile mode, which in turn
causes the driver to create a single CompileJobAction for all inputs. This mode
also prevents the creation of a MergeModuleJobAction, since we can rely on the
frontend to generate a full swiftmodule.
This mode will allow the driver to properly compile the stdlib; if this mode is
necessary for other inputs, we can rename and publicize this option.
Swift SVN r12612
Introduced OutputInfo::Mode and OutputInfo::CompilerMode, which dictate how the
driver should invoke the integrated frontend. Currently, there are three
options:
- StandardCompile: invoke the frontend once-per-input, using -primary-file
- REPL: invoke the frontend as the REPL
- Immediate: invoke the frontend in immediate mode
Updated buildOutputInfo() to properly set the CompilerMode, and updated
buildActions() and Swift::constructJob() to honor the CompilerMode.
With these changes, "swift_driver" (with no inputs) and "swift_driver -repl"
should invoke the REPL, and "swift_driver -i" should invoke the frontend in
immediate mode.
Swift SVN r12547
If the Swift tool is told to generate a command which produces a swiftmodule
additional output, pass -emit-module and -module-output-path. (Note that nothing
sets up this additional output yet; support for that is forthcoming.)
Swift SVN r12493
Added a MergeModuleJobAction, which will be translated into a Command which merges swiftmodule files.
Added a MergeModule subclass of Tool, which will generate a Command which merges swiftmodule files. (Currently, it generates a Command which invokes “swift_driver -frontend -help”.)
Added ToolChain-level support for getting the MergeModule Tool.
Nothing produces MergeModuleJobActions yet; adding that to the Action dependency graph should be enough to get this going.
Swift SVN r12491
This will allow the driver to specify the location for, among other things, the partial swiftmodule generated by a single frontend invocation.
Swift SVN r12449
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.
Swift SVN r12443
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.
Swift SVN r11375
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.
