Specifically the option: -sil-stop-optzns-before-lowering-ownership. This makes
it possible to write end-to-end tests on OSSA passes. Before one would have to
pattern match after ownership was lowered, losing the ability to do finegrained
FileCheck pattern matching on ossa itself.
Adjust the serialized module loader to allow directory layouts for the
Swift module on non-Darwin targets, unifying the layout across all the
platforms. It also eases cross-architecture and cross-platform
development by having the same layout, which can enable more similar
flag usage.
Tying InputFile to this option meant that every input that was not one of the explictly-blessed kinds was modeled as a Swift file.
With the new InputFile that infers file kinds, we no longer need CompilerInvocation::setInputKind
These inputs were previously modeled as Swift files, which would lead to bizarre situations where parts of the pipeline expecting Swift inputs actually wound up parsing Objective-C.
This scanning mode allows swift-driver to query module dependencies in a batch
and in a more granular way. In short term, it could help solve a problem that
clang module dependencies may vary if target triple changes. In a longer term,
we could break a holistic dependencies graph into smaller pieces for better caching
and reusing.
This change doesn't include the implementation of using the specified scanner
arguments to set up Clang dependencies scanner. It will come in later commits.
Add a debugging mechanism that enables the JIT to dump the LLVM IR and
object files to enable debugging the JIT. This makes it easier to debug
the JIT mode failures. The idea was from Lang Hames!
- deduplicate the logic to compute the resource folder
- install headers and module files in shared and static resource folders
- forward -static flag when calling swiftc with -print-target-info
Print implementation-only imports in the private textual interface
only if also importing SPI. This allows to export types from
implementation-only imports in SPI and brings the private textual
interfaces in line with the binary interfaces.
This is a temporary solution as we need to better design the language
feature around this.
This feature requires passing -experimental-spi-imports to the frontend
that generates the private swiftinterface file.
