On 64-bit platforms we reserve the maximum size of a WebAssembly memory. Thereby the memory can grow in-place. On 32-bit platforms, however, we allocate only the initial size, and grow the memory by reallocating the memory. Due to memory fragmentation the memory therefore cannot grow big. With this CL we allow to reserve 1GB of memory even on 32-bit platforms. Thereby the memory can grow to at least 1GB.

Mike Stanton authored
Code objects are exposed through JSFunction and SharedFunctionInfo. If they are builtins, we don't have to worry about background threads seeing partially initialized code objects. If they are optimized code objects, we may. Background threads read the code fields with AcquireLoad semantics. The fields are set on the main thread with ReleaseStore semantics when appropriate. Special care is taken when setting an optimized code object in a closure in the interpreter entry stub. Since the MacroAssembler doesn't support ReleaseStore semantics, this CL ensures that the optimized code object is stored with those semantics in the feedback vector, where the interpreter entry stub finds it.

We can use UseScratchRegisterScope instead of requiring a TempSimd128Register in the instruction-selector. This reduces register pressure a little bit (when combined with unique register constraints). Drive-by cleanup of some variable names in code-generator, s/tmp2/tmp/ when there is only 1 tmp.

The atomic pause would not report any marked bytes which in turn would mean that the used bytes counter would stay at 0 for testing GCs that always use atomic marking.

My recent change https://crrev.com/c/v8/v8/+/2698057 changed the size of bytecode for most functions, and attempted to update other heuristic values to match. However, it caused V8 to be slightly too eager to perform on-stack replacement in JetStream 2's gaussian-blur test case, so that the function got compiled separately for each of two nested loops rather than just once for the outer loop. This is the smallest change that restores the previous behavior in that benchmark.
