[AUTO_GENERATED] Migrate compiletest to use `ui_test`-style `//@` directives 2024-02-22 16:04:04 +00:00

Arlie Davis e11d8d147b Add support for generating the EHCont section
In the future Windows will enable Control-flow Enforcement Technology
(CET aka Shadow Stacks). To protect the path where the context is
updated during exception handling, the binary is required to enumerate
valid unwind entrypoints in a dedicated section which is validated when
the context is being set during exception handling.

The required support for EHCONT has already been merged into LLVM,
long ago. This change adds the Rust codegen option to enable it.

Reference:

This also adds a new `ehcont-guard` option to the bootstrap config which
enables EHCont Guard when building std.
