Bug 1654935 - Copy over COOP header from new document to the docshell in nsPrintObject; r=nika The COOP header is set to BrowsingContext only in Document::StartDocumentLoad. If the replaced document has a different COOP header from one in its docshell. Then, we can crash while creating a window global child for a new inner window.

Bug 1655928 - Add SpiderMonkey-side artefacts to support Wasm Atomics on Cranelift/newBE/AArch64 (CL PR2077). r=cfallin. Cranelift PR2077 adds support for Wasm Atomics via the newBE/AArch64 pipeline. This requires a few changes on the SM side: * a change to compiler gating logic, allowing CL on AArch64 to support threads/atomics * translation of WaitI32/WaitI64/Notify requests into the relevant SM-side instance calls - three more BD_SymbolicAddress:: values - a binding for CL's HeapMisaligned trap code, which is new - in wasm2clif.rs, a new error-reporting mode: IsNegative32, and handling thereof - in wasm2clif.rs, translation of wait_i32/wait_i64/notify to instance calls Differential Revision: https://phabricator.services.mozilla.com/D85760

Bug 1657024: Simplify code that's effectively walking the nsPageContentFrame continuation chain. r=TYLin Before this patch, we used a clumsy "GetNextPage" helper-function (which, despite its name, actually gets the next page **content** frame). It worked by pointer-chasing to get the parent's next-sibling's first-child. This is unnecessary; we can just directly query for the nsPageContentFrame's next-continuation, since these frames are linked in a straightforward continuation chain. Note that GetNextContinuation() is a virtual function-call, but it may still be faster than the pointer-chasing that we were doing with the GetNextPage() API. Moreover, we can help the compiler devirtualize it by static_cast'ing to the concrete type before calling the method. This is safe since nsPageFrame always contains a single nsPageContentFrame (which we already validate -- at least the frame-type-part -- via assertions).

Bug 1657073. Make sure to destroy direct manipulation objects before we clear our HWND pointer. r=kats Otherwise when we try to call Deactivate on the direct manipulation manager (to balance the Activate call) we won't have the HWND pointer and so it won't balance and we will leak. We call DestroyDirectManipulation in nsWindow::Destroy but it looks like nsWindow::OnDestroy can be called before nsWindow::Destroy.

Bug 1644513: Check maximum nesting depth before compiling regexp r=nbp Pathological regexps can overflow the stack just from recursively walking the AST during compilation. One way to avoid this is by checking the AST ahead of time to make sure it is not too deep. This occurs on 32-bit and in some configurations on 64-bit. The visitor API for RegExpTree is sad and full of `void*` spiders, but I don't think it's worth upstreaming a patch to make it nicer. Note that this is not a complete fix. If the stack is already close to overflowing, then even a relatively shallow regexp might overflow. However: 1. While the code that walks the AST doesn't check for stack overflow, the parser code that creates the AST does. The parser does not recurse as deeply, which is why we can end up in this situation, but many overflow cases will fail cleanly during parsing instead of crashing while walking the AST. 2. This is becoming a fuzzblocker on arm64 (see bug 1655404), so even a partial fix is better than none. Differential Revision: https://phabricator.services.mozilla.com/D79182
