Prototype F32x4Relaxed(Min/Max) and F64x2Relaxed(Min/Max) operations for ARM. F32x4 variants map directly to vmin/vmax hardware instructions which are also used for F32x4(Min/Max) operations. The F64x2 variants are mapped in this implementation to Pmin/Pmax instructions as detailed in the github issue. https://github.com/WebAssembly/relaxed-simd/issues/33 Bug: v8:12284 Change-Id: I5ea939385fa0ae97bbdf776fc0b763cabb1b293c Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3501347Reviewed-by:

Store the free registers as a RegList rather than stack of Register values. This allows us to simplify some of the register freeing logic, including passing the current free set to nodes for use as temporaries. Drive-by: Replace ALWAYS_ALLOCATABLE_GENERAL_REGISTERS with ALLOCATABLE_GENERAL_REGISTERS, which is the more general list (the former is an implementation detail for optionally reserving a register for the cage register).

Leszek Swirski authored
LiveNodeInfo was stored in a Node->LiveNodeInfo map, which was never copied or merged alongside control flow. Lookups in this map were a bit part of register allocation time, and it was mostly duplicating data that was already in the ValueNode. So, instead of a separate LiveNodeInfo, store the current register allocation state directly on the ValueNode. This involves a bit of clobbering of state (in particular, we have to clobber the next_use id), but that doesn't matter since regalloc is a forward pass and with this change, it's less memory and zero map lookups. Measuring on a (very large) function, this reduces compile time from 300ms to 200ms.

On the first interrupt, a non-concurrent optimization to Maglev is requested, which the next call to the marked function will perform. - There is no support for tiering from Maglev to TF yet. - Maglev's language support is minimal and tests are not expected to pass with --maglev. - Disable --maglev by default for now.

According to the latest changes in wasm-gc, externref will be renamed to anyref, and will be assigned as the top of the reference type hierarchy. Since in the current wasm type system funcref is not a subtype of anyref, subtyping is now dependent on whether wasm-gc is enabled.

Before this CL Oilpan would schedule concurrent marking and sweeping even in the presence of --single-threaded-gc. This e.g. flakily breaks Blink tests that do not set up a thread-pool in certain configurations where they pass --single-threaded (implying --single-threaded-gc).

InitialValue needs to have a spill slot (e.g. for deopts) but shouldn't emit an actual spill (since they're already on stack). Drive-by, fix printing of Checkpoint and CheckMaps parameters.

GetFreeRegisters is supposed to find some number of free registers that the current node can use as safe temporaries, but they shouldn't be considered "allocated", as they will be free as soon as the node's code completes. Now we no longer decrement free_register_count_ in GetFreeRegisters, to avoid leaking registers allocated for temporaries.
