This emits the same attributes we place on allocator declarations
(and allocator definitions using `#[global_allocator]`) on the
definitions in the allocator shim as well, making sure that the
attributes are not lost if the allocator shim participates in LTO.
Use standard attribute logic for allocator shim2025-09-25T08:04:40+00:00Nikita Popovnpopov@redhat.com2025-09-19T12:53:16+00:00urn:sha1:d226e7aa93425ba2090f423642341a99ab047838
Use llfn_attrs_from_instance() to generate the attributes for the
allocator shim. This ensures that we generate all the usual
attributes (and don't get to find out one-by-one that a certain
attribute is important for a certain target). Additionally this
will enable emitting the allocator-specific attributes (not
included here).
This change is quite awkward because the allocator shim uses
SimpleCx, while llfn_attrs_from_instance uses CodegenCx. I've
switched it to use SimpleCx plus tcx/sess arguments where necessary.
If there's a simpler way to do this, I'd love to know about it...
Rename `llvm::Bool` aliases to standard const case2025-08-24T13:09:54+00:00ZalatharZalathar@users.noreply.github.com2025-08-24T10:49:32+00:00urn:sha1:b4e97e5d866dd43c110d337affc419d5ac482765
This avoids the need for `#![allow(non_upper_case_globals)]`.
