[PATCH 0/1] MR6992: configure: Define _load_config_used symbol in the cross-compiler test program.

[Jacek Caban (＠jacek)]

The load configuration is mandatory for ARM64EC binaries, and the MSVC linker emits a warning when it is missing. It makes sense, so I plan to add a similar warning to lld-link. Since the configure scripts treat linker warnings as errors, defining the load configuration ensures future compatibility.

Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:
