ahatanak added a comment.
ToT clang/llvm (without this patch) is turning the call to
`@objc_unsafeClaimAutoreleasedReturnValue` in the EH cleanup block into an
unreachable when compiling the following code. It looks like this happens
because the inliner isn't adding the funclet token, but it's not clear to me
whether this is a bug or not.
$ cat test.mm
void foo();
id noexcept_func() noexcept;
struct S0 {
id x;
~S0() {
noexcept_func();
}
};
void test_attr_claimRV() {
S0 s0;
foo();
}
$ clang++ -std=c++11 -fobjc-arc test.mm -O3 -S -o -
"-fobjc-runtime=ios-11.0.0" -target aarch64-unknown-windows-msvc
