Change builtin calls in wasm-compiler.cc to use CallBuiltinPointer rather than CallCodeObject which means they bypass the trampoline. Since the Code objects are no longer being called, remove them from the executable Code object allow-list in builtins.cc.

Now that embedded builtins are mandatory and non-embedded builtins no longer need to be supported, it is safe to embed the target of the CEntry builtin directly into the {WasmCompileLazy} builtin.

Changing the target of JSCall nodes (e.g. while lowering higher order calls) now preserves feedback and speculation mode to allow further (speculative) optimizations. A flag is introduced to mark feedback unrelated to the call target after such a transformation. This flag is used to prevent access to the feedback without the need to invalidate it.

Port b875f466 Original Commit Message: Reland "[compiler] Optionally apply an offset to stack checks" This is a reland of 4a16305b The original CL adjust only one part of the stack check, namely the comparison of the stack pointer against the stack limit in generated code. There is a second part: Runtime::kStackGuard repeats this check to distinguish between a stack overflow and an interrupt request. This second part in runtime must apply the offset just like in generated code. It is implemented in this reland by the StackCheckOffset operator and a new StackGuardWithGap runtime function. Original change's description: > [compiler] Optionally apply an offset to stack checks > > The motivation behind this change is that the frame size of an optimized > function and its unoptimized version may differ, and deoptimization > may thus trigger a stack overflow. The solution implemented in this CL > is to optionally apply an offset to the stack check s.t. the check > becomes 'sp - offset > limit'. The offset is applied to stack checks at > function-entry, and is set to the difference between the optimized and > unoptimized frame size. > > A caveat: OSR may not be fully handled by this fix since we've already > passed the function-entry stack check.

Currently atomic operations are only allowed on shared WebAssembly.memory. An attempt to use atomic operations otherwise is a validation failure, there is an ongoing attempt to allow Wasm atomic operations on any memory object. https://github.com/WebAssembly/threads/issues/144 This CL adds experimental support for allowing atomic operations on all memory objects behind the --wasm-atomics-on-non-shared-memory flag. Note that Wait/Notify may not work as expected as they have additional checks to ensure that the memory is a SAB.

The {SetTraceValue} method was only defined for a set of integer types, which sometimes lead to ambiguities when using types like {size_t}, {unsigned long} or the like (see https://crrev.com/c/1886912/1).

A window is a Blink concept. This API marks the context as backing a detached window. This doesn't necessarily mean that the context is detached. Every time a JS function is called within a context that has a non-zero DetachedWindowReason, Runtime::kReportDetachedWindowAccess is invoked, which will report this call to Blink via a callback, which in turn can report number of such calls via UKM metrics.

This reverts commit 94456e5c. Reason for revert: <INSERT REASONING HERE> Original change's description: > PPC/s390: Reland: [builtins] Move non-JS linkage builtins code objects into RO_SPACE > > Port 855591a5 > > Original Commit Message: > > 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. > > R=delphick@chromium.org, joransiu@ca.ibm.com, jyan@ca.ibm.com, michael_dawson@ca.ibm.com > BUG= > LOG=N > > Change-Id: Ibd0713a17df9c873692553f2d57f4ba36bcdb342 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1893746 > Reviewed-by: Junliang Yan <jyan@ca.ibm.com> > Commit-Queue: Milad Farazmand <miladfar@ca.ibm.com> > Cr-Commit-Position: refs/heads/master@{#64704} TBR=michael_dawson@ca.ibm.com,jyan@ca.ibm.com,joransiu@ca.ibm.com,delphick@chromium.org,miladfar@ca.ibm.com Change-Id: I808a4220892dcfef66b4b9d90ab43bf403d2e9b0 No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1894353Reviewed-by:
