Summary: This is a follow up patch to r346956 for the `SizeClassAllocator32` allocator. This patch makes `AddressSpaceView` a template parameter both to the `ByteMap` implementations (but makes `LocalAddressSpaceView` the default), some `AP32` implementations and is used in `SizeClassAllocator32`. The actual changes to `ByteMap` implementations and `SizeClassAllocator32` are very simple. However the patch is large because it requires changing all the `AP32` definitions, and users of those definitions. For ASan and LSan we make `AP32` and `ByteMap` templateds type that take a single `AddressSpaceView` argument. This has been done because we will instantiate the allocator with a type that isn't `LocalAddressSpaceView` in the future patches. For the allocators used in the other sanitizers (i.e. HWAsan, MSan, Scudo, and TSan) use of `LocalAddressSpaceView` is hard coded because we do not intend to instantiate the allocators with any other type. In the cases where untemplated types have become templated on a single `AddressSpaceView` parameter (e.g. `PrimaryAllocator`) their name has been changed to have a `ASVT` suffix (Address Space View Type) to indicate they are templated. The only exception to this are the `AP32` types due to the desire to keep the type name as short as possible. In order to check that template is instantiated in the correct a way a `static_assert(...)` has been added that checks that the `AddressSpaceView` type used by `Params::ByteMap::AddressSpaceView` matches the `Params::AddressSpaceView`. This uses the new `sanitizer_type_traits.h` header. rdar://problem/45284065 Reviewers: kcc, dvyukov, vitalybuka, cryptoad, eugenis, kubamracek, george.karpenkov Subscribers: mgorny, llvm-commits, #sanitizers Differential Revision: https://reviews.llvm.org/D54904 llvm-svn: 349138 |
