I tried the new pulled this branch with gcc14 imported.

Both stage 1 and stage 2 are passed. But stage 3 is failed with the below messages.

what version of Xcode are you using? (and on what version of macOS?)

--- have you tested GCC-13.1 in the same environment?

(at the moment we're in the run up to 12.3 release so my resources are tied up with testing that)

Xcode 14.3 macOS 13.3.1 (a) (22E772610a)

GCC-13 was ok.

What's the usage of the libitum library?

State 3 is passed if I disable it with the option --disable-libitm.

The generated gcc binary can also compile codes successfully. And the compiled macho executable runs ok.

the current sources I pushed yesterday build for me on: Arm64 Monterey with Xcode 14.3 CLT and SDK. x86_64 Ventura with Xcode 14.3 CLT and SDK.

For reference, libitm is used to support transactional memory accesses
