On clang-17 it works. So this should be a regression.
Example code:
template<typename T>
concept X = true;
template <X T>
class Y {
public:
Y(T y) { }
template <X U>
friend class Y;
};
template class Y<int>;
int main() {
Y y(0);

Fixes llvm#82258 (cherry picked from commit baf6bd3) [Clang] [Sema] Handle placeholders in '.*' expressions (llvm#83103) When analysing whether we should handle a binary expression as an overloaded operator call or a builtin operator, we were calling `checkPlaceholderForOverload()`, which takes care of any placeholders that are not overload sets—which would usually make sense since those need to be handled as part of overload resolution. Unfortunately, we were also doing that for `.*`, which is not overloadable, and then proceeding to create a builtin operator anyway, which would crash if the RHS happened to be an unresolved overload set (due hitting an assertion in `CreateBuiltinBinOp()`—specifically, in one of its callees—in the `.*` case that makes sure its arguments aren’t placeholders). This pr instead makes it so we check for *all* placeholders early if the operator is `.*`. It’s worth noting that, 1. In the `.*` case, we now additionally also check for *any* placeholders (not just non-overload-sets) in the LHS; this shouldn’t make a difference, however—at least I couldn’t think of a way to trigger the assertion with an overload set as the LHS of `.*`; it is worth noting that the assertion in question would also complain if the LHS happened to be of placeholder type, though. 2. There is another case in which we also don’t perform overload resolution—namely `=` if the LHS is not of class or enumeration type after handling non-overload-set placeholders—as in the `.*` case, but similarly to 1., I first couldn’t think of a way of getting this case to crash, and secondly, `CreateBuiltinBinOp()` doesn’t seem to care about placeholders in the LHS or RHS in the `=` case (from what I can tell, it, or rather one of its callees, only checks that the LHS is not a pseudo-object type, but those will have already been handled by the call to `checkPlaceholderForOverload()` by the time we get to this function), so I don’t think this case suffers from the same problem. This fixes llvm#53815. --------- Co-authored-by: Aaron Ballman <aaron@aaronballman.com> [InstCombine] Fix miscompilation in PR83947 (llvm#83993) https://github.com/llvm/llvm-project/blob/762f762504967efbe159db5c737154b989afc9bb/llvm/lib/Transforms/InstCombine/InstCombineCalls.cpp#L394-L407 Comment from @topperc: > This transforms assumes the mask is a non-zero splat.

[lldb] Fix cast failure in FindFieldInStructArray Complicated expressions in lldb broke the assumption that the expression is an identifier, thus we got a cast error. This fix removes that from happening and also fixes the bug that if the identifier is an array itself the last index specified in the input is used to index that variable itself. e.g 01 SAMPLE-TABLE. 05 TABLE-DEPTH OCCURS 3 TIMES. 10 TABLE-ROW OCCURS 3 TIMES. 15 TABLE-COLUMN OCCURS 3 TIMES PIC 9(8). Here TABLE-ROW(1, 2) means second element of TABLE-ROW OF TABLE-DEPTH(1). Revert "[lldb] Fix cast failure in FindFieldInStructArray" This reverts commit c1bab0e0b6a798698196434c7bb6cbe391fcdc1b.

If in the future we do support it, we would need to fix this again.

This ensures the vector always occupies a power of 2 number of bytes. A consequence of this is that vbool64_t, vbool32_t, and vool16_t can only be used with a vector length that guarantees at least 8 bits. [Docs] Fix documentation build.

Fixes llvm#82258 (cherry picked from commit baf6bd3) [Clang] [Sema] Handle placeholders in '.*' expressions (llvm#83103) When analysing whether we should handle a binary expression as an overloaded operator call or a builtin operator, we were calling `checkPlaceholderForOverload()`, which takes care of any placeholders that are not overload sets—which would usually make sense since those need to be handled as part of overload resolution. Unfortunately, we were also doing that for `.*`, which is not overloadable, and then proceeding to create a builtin operator anyway, which would crash if the RHS happened to be an unresolved overload set (due hitting an assertion in `CreateBuiltinBinOp()`—specifically, in one of its callees—in the `.*` case that makes sure its arguments aren’t placeholders). This pr instead makes it so we check for *all* placeholders early if the operator is `.*`. It’s worth noting that, 1. In the `.*` case, we now additionally also check for *any* placeholders (not just non-overload-sets) in the LHS; this shouldn’t make a difference, however—at least I couldn’t think of a way to trigger the assertion with an overload set as the LHS of `.*`; it is worth noting that the assertion in question would also complain if the LHS happened to be of placeholder type, though. 2. There is another case in which we also don’t perform overload resolution—namely `=` if the LHS is not of class or enumeration type after handling non-overload-set placeholders—as in the `.*` case, but similarly to 1., I first couldn’t think of a way of getting this case to crash, and secondly, `CreateBuiltinBinOp()` doesn’t seem to care about placeholders in the LHS or RHS in the `=` case (from what I can tell, it, or rather one of its callees, only checks that the LHS is not a pseudo-object type, but those will have already been handled by the call to `checkPlaceholderForOverload()` by the time we get to this function), so I don’t think this case suffers from the same problem.

On clang-17 it works. So this should be a regression.
