The {shrd} instruction was implemented with switched {src} and {dst} registers. The only users ({ShrPair} and {SarPair}) "fixed" this by passing switched registers again. This CL cleans this up, and adds some DCHECKs that are required for the logic in the pair-wise shifts to work correctly. Also, avoid an unneccessary shift by 0 on ia32.

Currently there are two ways wasm locations are represented in the inspector. This remains unchanged for now. Also, currently there are multiple ways location is represented within V8, with the line number sometimes being a function index and sometimes being 0, and the column number being a byte offset which is sometimes function relative and sometimes module relative. With this change, the line number is never used within V8 (it is always 0), and the column number is always a byte offset from the beginning of the module. This simplifies translation logic and keeps it in one place, and will simplify future changes to wasm location representation in the inspector API.

When running the tests with --turbo-stress-instruction-scheduling, there are crashes in the cases where there is no isolate, since we used the random generator from the isolate. This change introduces a RandomNumberGenerator to the instruction scheduler instead. We use the value from --random-seed for seeding the random number generator. We don't treat a zero value specially, as the feature is meant to be used with the test system which always sets a random seed and doesn't rely on default behaviour. This also means that the instruction scheduler will always produce the same result for the same input within the same run, which fixes another issue with the x64 jump optimisation: when that optimisation is enabled, the backend is ran twice, and previously it was producing a different schedule each time, thus collecting incorrect jump information.

Instead of inferring allow_codegen from the state of MaybeLocal<String>, return it separately. This allows to distinguish "could not stringify this object" from "block execution of this object", regardless of whether the object is a string or not. Currently, the hook can trigger an EvalError only if the original source was a string. Modify the logic so that one of the three mechanisms (unconditional, non-modifying, modifying) decides alone. Before, if the non-modifying callback rejected a value, the value would be forwarded to the modifying callback, but the unconditional would not forward to the non-modifying callback. This introduces a more uniform behaviour where the three mechanisms act in decreasing priority.

The heap profiler and debugger use allocation trackers to observe allocation events and need to disable inlined allocations temporarily. But if --no-inline-new is passed, they do not need to. However, when removing allocation trackers they would accidently enable it again.

Port 352bbb12 Original Commit Message: This is a reland of 855591a5 Fixes break in builds that verify ReadOnlyHeap by relaxing the requirement for Code objects to be in CODE_SPACE in PagedSpaceObjectIterator::FromCurrentPage. Original change's description: > Reland: [builtins] Move non-JS linkage builtins code objects into RO_SPACE > > Reland of https://chromium-review.googlesource.com/c/v8/v8/+/1795358. > > [builtins] Move non-JS linkage builtins code objects into RO_SPACE > > Creates an allow-list of builtins that can still go in code_space > including all TFJ builtins and a small manual list that should be pared > down in the future. > > For builtins that go in RO_SPACE a Code object is created that contains an > immediate trap instruction. Generally these Code objects are still no > smaller than CODE_SPACE Code objects because of the Code object alignment > requirements. This will hopefully be addressed in a follow-up CL either by > relaxing them or removing the instruction stream completely. > > In the snapshot, this reduces code_space from ~152k to ~40k (-112k) and > increases by the same amount. > > Change-Id: I76661c35c7ea5866c1fb16e87e87122b3e3ca0ce > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1893336 > Commit-Queue: Dan Elphick <delphick@chromium.org> > Reviewed-by: Jakob Gruber <jgruber@chromium.org> > Reviewed-by: Ulan Degenbaev <ulan@chromium.org> > Cr-Commit-Position: refs/heads/master@{#64700} R=delphick@chromium.org, joransiu@ca.ibm.com, jyan@ca.ibm.com, michael_dawson@ca.ibm.com BUG= LOG=N Change-Id: If150434119828a87e295b0639c934392812bb345 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1896904Reviewed-by:
