Now ReadOnlySpace is not a Space, it cannot be upcasted to it, so cast to BaseSpace as well. Fixes ubsan failure introduced by https://chromium-review.googlesource.com/c/v8/v8/+/2209060.

This changes ReadOnlySpace to no longer be a PagedSpace but instead it is now a BaseSpace. BasicSpace is a new base class that Space inherits from and which has no allocation methods and does not dictate how the pages should be held. ReadOnlySpace unlike Space holds its pages as a std::vector<ReadOnlyPage>, where ReadOnlyPage directly subclasses BasicMemoryChunk, meaning they do not have prev_ and next_ pointers and cannot be held in a heap::List. This is desirable since with pointer compression we would like to remap these pages to different memory addresses which would be impossible with a heap::List. Since ReadOnlySpace no longer uses most of the code from the other Spaces it makes sense to simplify its memory allocation to use a simple bump pointer and always allocate a new page whenever an allocation exceeds the remaining space on the final page.

This brings %DebugPrint(string) closer to %DebugPrint(object) by also including the pointer, object kind, and RO/old space. Especially the pointer can be useful while debugging. One could consider going even further end printing full details of the string object, e.g. first and second pointers for cons strings. Before: $ out/debug/d8 --allow-natives-syntax -e '%DebugPrint("abc");' DebugPrint: #abc 0x263f080402cd: [Map] in ReadOnlySpace [...] After: $ out/debug/d8 --allow-natives-syntax -e '%DebugPrint("abc");' DebugPrint: 0xa830824ffe1: [String] in OldSpace: #abc 0xa83080402cd: [Map] in ReadOnlySpace [...] Drive-by: Document string printing functions. Drive-by: Use PrintUC16 in spots that don't want a full debug print.

Fuzzilli is open source fuzzer by Samuel Groß (saelo@google.com) that can be used to find bugs in v8 javascript engine. As we want to automate fuzzing for current versions of v8, we want to merge fuzzilli toolkit into v8 code, so that fuzzer can automatically update to the newest version. So far Fuzzilli has been maintained at https://github.com/googleprojectzero/fuzzilli .

https://crrev.com/c/2072858 rewrote the implementation of non-unicode ignore-case matches to comply with the JS spec in some corner cases. It fixed character matches and character class matches. We missed a similar bug in the implementation of back references. This CL fixes that bug. The main change is in regexp-macro-assembler.cc, where CaseInsensitiveCompareUC16 is split into CaseInsensitiveCompareUnicode (which has the same semantics as before) and CaseInsensitiveCompareNonUnicode (which has the semantics described here: https://tc39.es/ecma262/#sec-runtime-semantics-canonicalize-ch). Most of the rest of the patch undoes https://crrev.com/c/2081816 to once again make the unicode flag available to the macroassembler, so that we can decide which helper function to call. The testcase is a version of test/intl/regress-10248.js, modified to test backreferences.

This CL makes the test stricter by requiring specific string shapes; before it was possible to skip verification if strings were short-circuited, which I believe is no longer possible due to thin strings. I also added a regression test for the linked bug, which requires a String.p.split call on a two-byte-in-one-byte string with an empty string separator argument.

It's possible for a one-byte string to wrap a two-byte string. For example: CONS_ONE_BYTE_STRING_TYPE wraps THIN_STRING_TYPE wraps EXTERNAL_INTERNALIZED_STRING_TYPE We thus have to validate the extracted instance type when relying on the string being one-byte.

In production, we will always pass a pointer to the decoded module. The only reason for the existance of the nullptr checks is that tests sometimes don't pass a module here. Hence we pay in production code for a test-only feature. This CL fixes this by always passing a module pointer from the decoder tests. This even simplifies the code a lot by removing redundant code. The {TestModuleBuilder} class was moved before the definitions of the {FunctionBodyDecoderTest} class in order to be able to reuse it there. It's unmodified otherwise.

The SourcePositionTableBuilder unconditionally allocates heap memory for every Liftoff compilation. This shows up with 1-2% of compilation time in profiles. Hence move the vector contained in the SourcePositionTableBuilder into the compilation zone. Such a zone already exists for both Liftoff and TurboFan, so we can easily save allocations this way.

This change adds more granular control to the behavior that was previously controlled by the single flag --turbo-profiling. With this change, it becomes possible to: - output information only about builtins, ignoring functions compiled at runtime - skip the very slow process of writing the schedule and disassembly for all builtins, if you only want the block counts and don't need verbose output This change also moves the output step from Shell::OnExit to Isolate::DumpAndResetStats so that it's more consistent with other features and works in hosts other than d8.
