The mid-tier register allocator could not handle the case that the same virtual register was used for - the input corresponding to the 'same-as-input' output, and - another 'unique register' input. In this case, it cannot choose the already assigned register for the 'unique' register. Instead, it needs to allocate a new register and introduce a gap move to duplicate the input value in two different registers. FYI, the instruction where the current logic failed was: (v5(0), v6(R)) = IA32AddPair v7(R) v7(*) v8(R) v7(R) (where the last input was marked 'unique').

We switch the order of inlining and loop unrolling optimizations. This gives small improvements to wasm-gc benchmarks. Changes: - Change the loop analysis algorithm to accept loops directly connected to the graph's end. This is required because some nodes in an inlined function, such as tail calls, might be directly connected to the outer function's end without an intervening LoopExit node. - Based on the above, skip emitting loop exits for some Throw nodes in WasmGraphBuildingInterface. - Introduce WasmInliningPhase, add it before loop unrolling. Remove inlining from WasmOptimizationPhase. - Handle graph terminators in loop unrolling. - Add loops in the inlined function to the callers loop_infos. Drive-by: - Allow more wasm builtins in unrolled loops. - Reduce inlining parameters to reflect that functions are now slightly smaller during inlining, as no unrolling has taken place yet.

In the WebAssembly Turbofan pipeline, inlining should come before unrolling. When we inline a function, we link unhandled throwing calls in it to the handler of the caller node. If a throwing call is in a loop, we need to generate loop exits between the call and the handler if we want to unroll later. This CL adds dangling IfException/LoopExit nodes following each throwing call in an inlined function. These nodes are connected as required in inlining. Drive-by: Remove CheckForException from tail calls, which are kNoThrow.

This CL renames a number of things related to the V8 sandbox. Mainly, what used to be under V8_HEAP_SANDBOX is now under V8_SANDBOXED_EXTERNAL_POINTERS, while the previous V8 VirtualMemoryCage is now simply the V8 Sandbox: V8_VIRTUAL_MEMORY_CAGE => V8_SANDBOX V8_HEAP_SANDBOX => V8_SANDBOXED_EXTERNAL_POINTERS V8_CAGED_POINTERS => V8_SANDBOXED_POINTERS V8VirtualMemoryCage => Sandbox CagedPointer => SandboxedPointer fake cage => partially reserved sandbox src/security => src/sandbox This naming scheme should simplify things: the sandbox is now the large region of virtual address space inside which V8 mainly operates and which should be considered untrusted. Mechanisms like sandboxed pointers are then used to attempt to prevent escapes from the sandbox (i.e. corruption of memory outside of it). Furthermore, the new naming scheme avoids the confusion with the various other "cages" in V8, in particular, the VirtualMemoryCage class, by dropping that name entirely. Future sandbox features are developed under their own V8_SANDBOX_X flag, and will, once final, be merged into V8_SANDBOX. Current future features are sandboxed external pointers (using the external pointer table), and sandboxed pointers (pointers guaranteed to point into the sandbox, e.g. because they are encoded as offsets). This CL then also introduces a new build flag, v8_enable_sandbox_future, which enables all future features.

This is the final change list in the list of refactorings to split off the implementations of v8::StackFrame and CallSite objects (as used by the V8 JavaScript stack API). See https://bit.ly/v8-stack-frame for the whole story. This CL adds the v8::internal::StackFrameInfo class as new backing implementation of v8::StackFrame, and puts it into debug-objects.tq to indicate that it's used for the debugger API only. This new class is lightweight and only holds on to static information about the stack frame, and is thus usable for the V8 inspector to implement async stack traces in a cheaper manner going forward.

On some branches of the search tree for a binary-search switch, the input value is sufficiently constrained that we could unconditionally jump to the last possible case rather than checking for value equality. This shortens some builtins by a few instructions and might speed things up, though I expect the effect to be small.

This decouples the stack trace visitation logic from the creation of actual stack frame objects, in preparation to introduce a second kind of stack frame object (`v8::internal::StackFrameInfo` as part of http://crrev.com/c/3302794) in addition to the existing `v8::internal::CallSiteInfo`.
