This is probably not what the user wants: error: nested Markdown emphasis in HTML `style` tag --> $DIR/invalid-html-tags-correct-script-style.rs:11:16 | LL | /// One <style>*emph*</style> | ^^^^^^ Markdown translates this into HTML, but the browser parses it as CSS | help: to turn off Markdown parsing, put the tag at the start of the line | LL ~ /// One LL ~ /// <style>*emph*</style> |

The `test_dir_remove_file` test currently fails under Windows 7 on: ``` thread 'fs::tests::test_dir_remove_file' (2028) panicked at library/std/src/fs/tests.rs:2590:5: dir.remove_file("foo.txt") failed with: The parameter is incorrect. (os error 87) ``` Looking into it, this is because the `FILE_DISPOSITION_INFO_EX` variant of the `SetFileInformationByHandle` API is used while it is only available starting from Windows 10 1607. However, `FILE_DISPOSITION_INFO` is still available since Vista. This is therefore fixed by introducing a fallback to the latter API if the former fails. This is achieved by re-using some logic that is already available through `File::delete` and that does exactly this. Signed-off-by: Paul Mabileau <paul.mabileau@harfanglab.fr>

Canonicalize and evaluate next-gen region constraints before query response canonicalization so equivalent constraints merge structurally.

Cover the dyn object supertrait case that used to leave equivalent next-gen region constraints in different shapes.

This is currently a no-op, but will be useful when const in `global_asm!` can be pointers.

Currently global_asm already have symbol names when using v0 scheme, this makes them obtain symbols with legacy scheme too.

This gives the asm-const code the basic ability to deal wiht pointer and provenances, which lays the ground work for asm_const_ptr. Note that `SymStatic` is not fully removed, a specialized is kept and renamed as `SymThreadLocalStatic`, for `#[thread_local]` statics where CTFE does not support naming. The `#[thread_local]` is unstable feature and it's not clear if we want to support this in `sym`, but removal of it should be a separate PR.

With the previous commit, now we can see there are some code duplication for the handling of `GlobalAlloc` inside backends. Do some clean up to unify them.

CTFE pointers created via type ID, `without_provenance` or pointers to const ZSTs can now be codegenned with all 3 backends. These pointers are generated in the same way as integers.

…_attrs enabled

also add a test for cross-crate static initializers

…ef const after scheduling. That works only when a later phase emits a real diagnostics. For function item (associated fn), the lowering needs parent trait and self args

The backend now fully supports codegen of const pointers, remove the block inside typeck behind a new feature gate. Tests are also added.
