…ted parameters after last function parameter"
swift-5.2-branch doesn't indent the contents of var decl accessor blocks if the var decl is a direct child of an ifconfig decl on swift-5.2-branch. It works correctly on master after the recent indentation overhaul, but we didn't have a test covering that specific case. Resolves rdar://problem/60292681
Add a request to lookup all implied conformances for use while typechecking the primary. This provides a cache-point for evaluator-based dependency tracking.
…LASS prefixes" For clang decls marked with SWIFT_CLASS, these explicit class initializer symbols turn out to be necessary in the TBD files. rdar://60857470
… block arguments.
RedundantPhiElimination eliminates block phi-arguments which have the same value as other arguments of the same block.
This also works with cycles, like two equivalent loop induction variables. Such patterns are generated e.g. when using stdlib's enumerated() on Array.
preheader:
br bb1(%initval, %initval)
header(%phi1, %phi2):
%next1 = builtin "add" (%phi1, %one)
%next2 = builtin "add" (%phi2, %one)
cond_br %loopcond, header(%next1, %next2), exit
exit:
is replaced with
preheader:
br bb1(%initval)
header(%phi1):
%next1 = builtin "add" (%phi1, %one)
%next2 = builtin "add" (%phi1, %one) // dead: will be cleaned-up later
cond_br %loopcond, header(%next1), exit
exit:
Any remaining dead or "trivially" equivalent instructions will then be cleaned-up by DCE and CSE, respectively.

Fix the tests after 45dc14a.
Some bad interactions with StdlibUnittest and XCTest lead to sporadic test timeouts for this test. Given that the codebase is obsolete, the best option seems to be to stop running this test altogether. All we really care is that the resulting dylib still contains the right symbols, and building (but not running) this test seems to be a reasonable way of doing that.
[NFC] Add LookupConformancesInContextRequest

Add type checking for `@differentiable` function types: - Check that parameters and results conform to `Differentiable`. - Implicitly conform parameters and results whose types are generic parameters to `Differentiable`. - Upstream most of the differentiable_func_type_type_checking.swift test from `tensorflow` branch. A few function conversion tests have not been added because they depend on the `@differentiable` function conversion pipeline. Diagnose gracefully when the `Differentiable` protocol is unavailable because `_Differentiation` has not been imported. Resolves TF-823 and TF-1219.
…ession-test [test] Add indentation regression test.
…tlang#30660) Add the `@differentiable` function conversion pipeline: - New expressions that convert between `@differentiable`, `@differentiable(linear)`, and non-`@differentiable` functions: - `DifferentiableFunction` - `LinearFunction` - `DifferentiableFunctionExtractOriginal` - `LinearFunctionExtractOriginal` - `LinearToDifferentiableFunction` - All the AST handling (e.g. printing) necessary for those expressions. - SILGen for those expressions. - CSApply code that inserts these expressions to implicitly convert between the various function types. - Sema tests for the implicit conversions. - SILGen tests for the SILGen of these expressions. Resolves TF-833.
