Since `DYNAMICBASE` is widely preferred for security purposes, this provides just-enough granularity to close [#58480](https://bugs.winehq.org/show_bug.cgi?id=58480), and matches more closely to that of cygwin and MSVC compilers. Note that this `HIGHENTROPYVA:NO` solution is new information since creating that bug report. On the other hand, if it's winehq's stance that these flags should be toggled together, I'd happily change this back. I was fearful that handling them together may not be succinct enough, but I'm happy to oblige. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8786#note_113319

[PATCH v2 0/3] MR8774: vccorlib140: Add an initial implementation for allocation primitives.
by Vibhav Pant (＠vibhavp) Aug. 20, 2025

Aug. 20, 2025

The `Allocate` method has two variants: * Allocate(size_t): Performs a normal allocation, but throws a COMException on OOM. * Allocate(ptrdiff_t offset, size_t size): Allocates a block of size `size`, and initializes a control block for an `IWeakReference` at `offset`. The weak reference resolves to the allocated object, which can finally be freed by calling `ControlBlock::ReleaseTarget`. The IWeakReference implementation seems to be rather odd, which I have tried to demonstrate (and test) in the unit tests: * `ReleaseTarget` only frees the object if the strong ref count is _below_ 0. * `IWeakReference::Resolve` will _not_ set the output pointer to `NULL` if the weak reference is no longer alive. This MR implements these functions sans exception support. -- v2: vccorlib140: Implement Platform::Details::{Allocate(ptrdiff_t, size_t), ControlBlock::ReleaseTarget}. vccorlib140: Add stub for Platform::Details::{Allocate(ptrdiff_t, size_t), ControlBlock::ReleaseTarget}. https://gitlab.winehq.org/wine/wine/-/merge_requests/8774

I've added a second flag for `HIGHENTROPYVA`. This new flag is longer and breaks some styling. Any advice is greatly appreciated. I've placed the style foopahs inline. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8786#note_113299
