Thanks to the way we've set up our diagnostics engine, there's not actually
a reason for /everything/ to get rebuilt when /one/ diagnostic changes.
I've split them up into five categories for now: Parse, Sema, SIL, IRGen,
and Frontend, plus a set of "Common" diagnostics that are used in multiple
areas of the compiler. We can massage this later.
No functionality change, but should speed up compile times!
Swift SVN r12438
Added support for the -emit-module and -module-output-path options. -emit-module
and -module-output-path function similarly to -serialize-diagnostics and
-serialized-diagnostics-path: notably, -module-output-path implies -emit-module,
but -emit-module can be passed without -module-output-path and a default path
will be determined based on other inputs.
Added support for the -module-link-name option, which specifies the name of the
library to link against when importing the generated module.
Note that support for these options is only implemented in the integrated
frontend; driver-level support for these options is forthcoming.
Swift SVN r12301
Reworked the -serialize-diagnostics option, so that it is now just a flag
indicating that the frontend should generate serialized diagnostics. The path at
which the diagnostics will be serialized is now specified by the
-serialized-diagnostics-path option, which is a frontend-only option. (The
frontend treats -serialized-diagnostics-path as implying -serialize-diagnostics.)
If -serialize-diagnostics is passed but -serialized-diagnostics-path is not
passed, the frontend will choose an output path from a few default values:
- If the frontend has a non-stdout output path, replace that path's extension
with .dia.
- If there is a primary input filename, use that input's base name as the base
name for the serialized diagnostics file.
- Otherwise, use the module name as the base name for the serialized diagnostics
file.
Added support for setting up a serialized diagnostics DiagnosticConsumer in
frontend_main() if FrontendOptions::SerializedDiagnosticsPath is non-empty.
Swift SVN r12251
MainInputFilename and OutputFilename are pulled from the FrontendOptions, while Triple is parsed directly from the ArgList.
Eventually, MainInputFilename and OutputFilename should likely be removed from IRGenOptions, in favor of the values in FrontendOptions, while Triple will be in a separate TargetOptions class.
Swift SVN r11455
Moved the responsibility for storing LinkLibraries from CompilerInvocation to the invocation’s IRGenOpts.
Moved the handling of -l and -framework into ParseIRGenArgs.
Swift SVN r11450
The integrated frontend now supports:
- Parse
- DumpParse
- DumpAST
- PrintAST
- EmitSILGen
- EmitSIL
- EmitIR
- EmitBC
- EmitAssembly
- EmitObject
Moved the code for compiling into a separate performCompile() function in frontend_main.cpp, to facilitate using early returns while still supporting the diagnostic verifier.
Added some error output for the REPL, Immediate, and EmitModuleOnly actions, as the integrated frontend does not yet support these actions.
Swift SVN r11387
Added PrintHelp and PrintHelpHidden to FrontendOptions.
Marked both -help and --help-hidden with the FrontendOption flag.
Updated ParseFrontendArgs to parse -help and --help-hidden.
Updated frontend_main() so that it prints the help for the frontend options.
Swift SVN r11320
Added a new DiagnosticOptions class to swiftBasic, and added a DiagnosticOptions member to CompilerInvocation.
Added a static ParseDiagnosticArgs function to parse diagnostic-related arguments.
Added -verify to FrontendOptions.td, and added support for parsing -verify in ParseDiagnosticArgs.
Updated frontend_main() to enable and trigger the DiagnosticVerifier when -verify is passed.
Swift SVN r11318
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.)
