| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [Clang][NFCI] Cleanup the fix for default function argument substitution (#104911) (This is one step towards tweaking `getTemplateInstantiationArgs()` as discussed in https://github.com/llvm/llvm-project/pull/102922) We don't always substitute into default arguments while transforming a function parameter. In that case, we would preserve the uninstantiated expression until after, e.g. building up a CXXDefaultArgExpr and instantiate the expression there. For member function instantiation, this algorithm used to cause a problem in that the default argument of an out-of-line member function specialization couldn't get properly instantiated. This is because, in `getTemplateInstantiationArgs()`, we would give up visiting a function's declaration context if the function is a specialization of a member template. For example, ```cpp template <class T> struct S { template <class U> void f(T = sizeof(T)); }; template <> template <class U> void S<int>::f(int) {} ``` The default argument `sizeof(U)` that lexically appears inside the declaration would be copied to the function declaration in the class template specialization `S<int>`, as well as to the function's out-of-line definition. We use template arguments collected from the out-of-line function definition when substituting into the default arguments. We would therefore give up the traversal after the function, resulting in a single-level template argument of the `f` itself. However the default argument here could still reference the template parameters of the primary template, hence the error. In fact, this is similar to constraint checking in some respects: we actually want the "whole" template arguments relative to the primary template, not those relative to the function definition. So this patch adds another flag to indicate `getTemplateInstantiationArgs()` for that. This patch also consolidates the tests for default arguments and removes some unnecessary tests. This fixes a crash or assertion failure while building tests for the devel/hpx port. PR: 288352 MFC after: 3 days

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [Clang] Do not change the type of captured vars when checking lambda constraints When checking the constraint of a lambda, we need to respect the constness of the call operator when establishing the type of capture variables. In D124351, this was done by adding const to the captured variable... However, that would change the type of the variable outside of the scope of the lambda, which is clearly not the desired outcome. Instead, to ensure const-correctness, we need to populate a LambdaScopeInfo with the capture variables before checking the constraints of a generic lambda. There is no changelog as I'd like to tentatively propose we backport this change to RC3 as it is a regression introduced in the Clang 17 cycle.

This patch reveal a pre-existing issue. `this` is always recomputed by TreeTransform. `*this` (like all captures) only become `const` after the parameter list. However, if try to recompute the value of `this` (in a parameter) during template instantiation while determining the type of the call operator, we will determine it to be const (unless the lambda is mutable). There is no good way to know at that point that we are in a parameter or not, the easiest/best solution is to transform the type of this. Note that doing so break a handful of HLSL tests. So this is a prototype at this point.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [clang] Reset FP options before template instantiation AST nodes that may depend on FP options keep them as a difference relative to the options outside the AST node. At the moment of instantiation the FP options may be different from the default values, defined by command-line option. In such case FP attributes would have unexpected values. For example, the code: template <class C> void func_01(int last, C) { func_01(last, int()); } void func_02() { func_01(0, 1); } #pragma STDC FENV_ACCESS ON caused compiler crash, because template instantiation takes place at the end of translation unit, where pragma STDC FENV_ACCESS is in effect. As a result, code in the template instantiation would use constrained intrinsics while the function does not have StrictFP attribute. To solve this problem, FP attributes in Sema must be set to default values, defined by command line options. This change resolves https://github.com/llvm/llvm-project/issues/63542.

The recursive lambda will cause a lambda function instantiated multiple times, one inside another. The inner LocalInstantiationScope should not be marked as MergeWithParentScope since it already has references to locals properly substituted, otherwise it causes assertion due to the check for duplicate locals in merged LocalInstantiationScope.

This uses the new layout of the upstream repository, which was recently migrated to GitHub, and converted into a "monorepo". That is, most of the earlier separate sub-projects with their own branches and tags were consolidated into one top-level directory, and are now branched and tagged together. Updating the vendor area to match this layout is next. Notes: svn path=/head/; revision=355940
