Renderer hangs are possible with current limit (25). I'd like to know what a limit of 15 does to benchmark performance, and see it's effect on hangs.

In the process: * Rework the Torque definition of ScopeInfo to enable direct field-style access of ScopeFlags, removing some dead code in the process. * Allow implicit FromConstexpr conversion from subtypes of 'constexpr A' to other types. This makes it possible/easy to convert constexpr versions of enums to other types, since the constexpr version of the enum isn't addressable. It's namespace isn't a valid namespace and is an implementation detail anyway. * Cleanup LanguageMode: Language mode is now an enum and directly mirrors the C++-side definition rather than being a Smi. With the changes above, a new type LanguageModeSmi is introduced that is the Smi representation of LanguageMode that can be implicitly casted from constexpr LanguageMode values.

kFpRegPair requires a bit of special case logic in allocation and spill logic, since it requires adjacent fp registers, with the low register being an even-numbered one. We make use of a shift+and trick with the reg list to check this. Given a bit mask of registers available, AND this with a right-shift-by-one version of itself, and then AND it again with with a bit mask of even numbered fp registers, we can get a bit mask where all available even registers are set. For example, given 00011011, where 1 means register is available: 00011011 & 0001101 (right shift by 1) ---------- 00001001 & 01010101 (mask of even registers) ---------- 00000001 We see that only the first fp register is available, based on the adjacency requirement. The mask of even registers is defined to be uint64_t, to workarond shift overflow issues when non-unsigned values are used, and also to make this work on all platforms and compilers without implicit conversion warnings. It is a bit wasteful, since we really only need storage_t, but since it is a constexpr it should be okay. The spilling case tries to be a bit smart, since there are three possible cases (described in the code), two of which we can spill one register, and in the last case we have to spill two registers. We try to distinguish between these cases in order to minimize spills. The dumb thing here is in the last case, we arbitrarily pick the first two registers (d0, d1) to spill.

This allows the definition of classes with several arrays and ports SmallOrderedHashTable subclasses to Torque as an example, including the existing CSA allocation functions for them. Overview of changes: - Introduce ResidueClass to encapsulate the modulo-arithmetic necessary to do alignment checks. - Add MachineOperatorReducer to the CSA pipeline to address now missing CSA ad-hoc constant folding that got blocked by a temporary phi. - Allow assignments to references to structs. This is needed to initialize the data_table part of SmallOrderedHashMap. - Make the NumberLiteralExpression AST-node store a double instead of a string. This is necessary to detect arrays with constant size used for padding. - Turn offsets into base::Optional<size_t> to ensure we don't use an invalid or statically unknown offset. - Remove CreateFieldReferenceInstruction since it doesn't work for complex offset computations and the logic can be expressed better in ImplementationVisitor. - Validate alignment of structs embedded in classes.

Change unregister tokens to be held weakly instead of strongly. This enables the use case for an object to be used as its own unregister token. To avoid using an ephemeron table, FinalizationGroup's key_map is changed to key off unregister tokens' identity hashes. Because hashes may collide, a single key list may rarely contain multiple tokens. When a FinalizationGroup WeakCell's token becomes unreachable, during GC, it is removed from the the doubly linked key list and removed from the key map if it had a unique key.

This change includes templatization of the test helper to allow the same function to be reused for both signed and unsigned data types.

It would be nice if unused {RegClass}es just equal {kNoReg} on all platforms. This CL adds the static asserts for that, and slightly modifies the definition of the {RegClass} enum to fulfil that. Interestingly, this only changes the values for the one configuration that is currently unused :) R=zhin@chromium.org Change-Id: Ib1b2a663183ad34822f514d6168c65450c1d7f2e Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1975753Reviewed-by:Zhi An Ng <zhin@chromium.org> Commit-Queue: Clemens Backes <clemensb@chromium.org> Cr-Commit-Position: refs/heads/master@{#65527}

For functions which check if a register pair is used, change them from is_gp_pair to is_pair, since they do not care if the pair of register is a gp pair or a fp pair.

For Smi, we can avoid calling the ToNumber builtin, and also the conversion to float and back. This adds some complexity, but greatly improves performance for parameters that fit in a Smi.
