Doing the bounds check in C++ has the advantage that we generate less code, and that TurboFan graphs get smaller. Additionally it will make code generation from Liftoff easier. There is not really a downside: We already called C++ anyways to do the actual memory.fill operation.

The {TYPE_CHECK} macro used an ancient pattern to check for assignability, by assigning to a static_casted nullptrs of the respective types. C++11 introduced standard library helpers to express this more naturally. The most direct translation would have been to use {std::is_assignable} or {std::is_convertible} on the pointer types, but in most cases we can be even more strict and force one type to be a proper subtype of the other. The only exception is {ReturnValue}, which allows to assign anything if it's void.

This change is based on a discussion from https://crrev.com/c/v8/v8/+/2053769/4/src/compiler/machine-operator-reducer.cc#1696 wherein Tobias suggested moving the folding away of ==0 operations out of the platform-specific instruction selectors and into the MachineOperatorReducer. I noticed that CommonOperatorReducer already handles some very similar cases, so I have tried putting the ==0 folding into CommonOperatorReducer instead. I'm happy to move it into MachineOperatorReducer if that's better; I still don't have a very good understanding of how roles are separated among reducers.

This is a grab-bag of small compatibility fixes to make it easier to import irregexp into SpiderMonkey. For changes where the commit message was longer than the change itself, it didn't seem worth opening a separate review. [regexp] Use uc16 in FilterOneByte SpiderMonkey uses char16_t instead of uint16_t for its two-byte strings. (This matches ICU. It looks like V8 considered making the same change, but decided against it: see https://bugs.chromium.org/p/v8/issues/detail?id=6487.) Fortunately, irregexp is careful about only using uc16, so SpiderMonkey can just define uc16 = char16_t and *almost* everything works out. This patch fixes the single place in irregexp where that is not true. [regexp] Remove unreachable return The return statement at the end of RegExpParser::ParseClassCharacterEscape is unreachable, because every branch of the switch returns. This triggered static analysis errors in SpiderMonkey. [regexp] Remove trivial assertion The assertion in BytecodeSequenceNode::ArgumentMapping cannot fail, because size_t is an unsigned type. This triggered static analysis warnings in SpiderMonkey. [regexp] Make RegExpStack constructor public In V8, the RegExpStack's private constructor is called from Isolate, which is a friend class. In SpiderMonkey, we use a wrapper around new to control where memory is allocated, so we need the RegExpStack constructor to be visible outside of Isolate. [regexp] Refactor Isolate::IncreaseTotalRegexpCodeGenerated The call-site of Isolate::IncreaseTotalRegexpCodeGenerated is the only place inside irregexp where HeapObject::Size is called. SpiderMonkey's heap-allocated objects live in arenas, and don't have a standardized way of finding the size. In this particular case it would be safe to hardcode a size of 0, but leaving HeapObject::Size undefined will ensure that SpiderMonkey doesn't silently do the wrong thing if somebody in V8 adds a new, more meaningful call to HeapObject::Size.

For a variety of reasons related to OOM handling and custom allocators, SpiderMonkey wants to be able to see all memory allocations. To enforce this, we have a static analysis that verifies that we don't link in malloc/new/etc in unexpected places. One consequence of this is that we can't use STL containers without a custom allocator, because they call operator new internally. This is mostly not an issue in irregexp, which makes heavy use of zone allocation. The main exceptions are a handful of uses of std::vector in regexp-compiler.* and regexp-parser.*. If these vectors are converted to ZoneVectors, then our static analysis is satisfied.

Unlike the other RegExpTree types, RegExpCapture and RegExpGroup don't cache their min/maxMatch value. Instead, they compute it by recursing on the min/maxMatch of the body node. In pathological cases, with sufficiently small stacks, this can cause stack overflow. (In SpiderMonkey's case, it was a worker on 32-bit x86.) It's easy enough to just precompute the value when the body is set.

TextEmitPass uses a function pointer to determine which pass to call. This function pointer is only assigned inside TextEmitPass, and can easily be eliminated by moving the calls to each possible target inside the switch statement that assigns the function pointer. I made this change because SpiderMonkey uses a static analysis pass to verify that everything is rooted properly across calls that might GC, and that analysis is conservative when calling function pointers. We can white-list function pointers that are known to be safe, but the code being called through this function pointer is complex enough (and the function pointer is unnecessary enough) that it seemed best to just remove the function pointer entirely.

The return value of {memory_init_wrapper} was defined as {bool} in the original CL. When compiled with clang, the full return register is written when {true} or {false} is returned. With msvc, however, the return value is written as a single byte, without zero-extension. In generated code, the full return register is used and therefore stale bytes in the return register caused problems. With this CL the return value is changed to {uint32_t}. This enforces zero-extension of the return value and thereby fixes the issue.

This CL is a step towards making StackChecks implicit. In a follow-up CL said StackChecks will become implicit within JumpLoops.

The return value of {memory_copy_wrapper} was defined as {bool} in the original CL. When compiled with clang, the full return register is written when {true} or {false} is returned. With msvc, however, the return value is written as a single byte, without zero-extension. In generated code, the full return register is used and therefore stale bytes in the return register caused problems. With this CL the return value is changed to {uint32_t}. This enforces zero-extension of the return value and thereby fixes the issue.
