Swift class deinit decl can be implicitly synthesized when emitting
swiftmodule, so swiftmodule always have deinit decl. So resolution of
x-refs to deinit of swift class always success.
But when x-refs points deinit of clang imported class, it always failed
because clang importer doesn't force to synthesize deinit before looking
up.
x-refs to deinit decl appears in only deinit of its subclasses, so it's
serialized only when deinit have body. And deinit has body only on SIB
because deinit is always non-inlinable. It means that this missing of
deinit creation can be problem only on SIB
This commit changes to force to synthesize class deinit
decl before looking up members.
several more places to use getOrCreateHelperFunction.
This means that several of these places are now emitting
shared functions rather than private ones, which I've
verified is okay. There are some other places where
privacy is still unfortunately necessary.
I've also fixed the name of the store-extra-inhabitants
helper function to say "store" instead of "get", which
is longstanding (but harmless because it's private).
Fixes rdar://66707994.
subclassScope was always set as NotApplicable when deserialized but we
need to serialize and deserialize it to keep correct linkage when using
SIB
```swift
open class Visitor {
public func visit() {
visitExprImpl()
}
@_optimize(none)
private func visitExprImpl() {
}
}
```
In this case, `visitExprImpl` is private but subclassScope is External.
So it should be lowered as an external function at LLVM IR level.
But once it's serialized into SIB, subclassScope of `visitExprImpl` was
deserialized as NotApplicable because it was not serialized. This
mismatch makes `visitExprImpl` lowered as an internal function at LLVM
IR level.
So `subclassScope` should be serialized.
When there are sil_property and sil_differentiability_witness at once,
serialized file couldn't be deserialized because it's index table is
serialized un-sortedly but deserializer assumes that contents of table
index are sorted.
This patch fixes the un-sorted serialization and adds test case to
ensure that table index contents can be deserialized
In #30614, we started consuming XRefNonLoadedModuleErrors while loading
conformances, since a conformance to a type we cannot load usually
indicates we're trying to load a protocol that was declared in an
@_implementationOnly imported module.
We should also consume TypeErrors that we see where the underlying reason
is an XRefNonLoadedModuleError, since they're likely indicators of the
same thing.
…and modify resolveFileIDConflicts() to diagnose any such violations instead of asserting.
Swift does not allow any two files in the same module to have the same filename, even if they are in different directories. However, this is enforced in the driver, so tests that invoke the frontend directly can violate it. Turns out that a couple of those snuck into the test suite at various points.
This commit updates those tests. It also causes the frontend to diagnose the duplicate filename error just as the driver would have, which should help us understand what happened more easily if this crops up again in the future.
NFC, since invoking the frontend directly is unsupported.
Most of the changes fall into a few categories:
* Replace explicit "x86_64" with %target-cpu in lit tests
* Cope with architecture differences in IR/asm/etc. macOS-specific tests
Previously we were linking in all SIL entities
if the input was a serialized non-SIB AST, and
`-disable-sil-linking` wasn't specified. However
none of the tests appear to want this behaviour.
Stop calling `SerializedSILLoader::getAll`, and
remove the `-disable-sil-linking` option, as this
is now the default behaviour.
The ``base_addr_for_offset`` instruction creates a base address for offset calculations.
The result can be used by address projections, like ``struct_element_addr``, which themselves return the offset of the projected fields.
IR generation simply creates a null pointer for ``base_addr_for_offset``.
In order to access `stdin`, `stdout` as binary, you must use the
`buffer` member in Python 3. The replacement of the binary data
requires that pattern and the replacement be byte objects. Convert the
pattern and replacement to UTF-8 encoded bytes.
Swift calls the architecture x86_64, OpenBSD calls it amd64. If we use
run_cpu in lit.cfg as-is, then we may need to duplicate lines in each
test for 'x86_64' and 'amd64', which puts a maintenance burden on unit
test developers to ensure they are duplicating changes to each line.
Instead, alias 'amd64' to 'x86_64' for `run_cpu`, but keep the platform
module path referring to 'amd64', in order to distinguish the target
architecture name and the Swift architecture name. This is particularly
relevant for the %target-.*-name pseudovariables used, which should
reference the Swift architecture names.
However, some unit tests are directly referencing %target-cpu directly,
which would break the aliasing. This is done only for swiftinterface
files, so a new substitution is defined in lit.cfg for these variables,
and the affected unit test cases are migrated.
Hide comments from SPI decls in all swiftdoc files. This applies the
same restrictions as private declarations. This is a temporary solution,
a long term fix is to emit both a public and an internal swiftdoc file.

* a new [immutable] attribute on ref_element_addr and ref_tail_addr
* new instructions: begin_cow_mutation and end_cow_mutation
These new instructions are intended to be used for the stdlib's COW containers, e.g. Array.
They allow more aggressive optimizations, especially for Array.
The `-force-single-frontend-invocation` flag predates WMO and is now an
alias for `-whole-module-optimization`. We should use the latter and let
the former fade into history.
