In gdbbjit's event handler, we return early if code_type is not JIT_CODE. Unfortunately, in all CodeLinePosInfo event, we memset the struct, so code_type is always BYTE_CODE, so no line information was getting saved. Drive-by clean up to aggregate initialize JitCodeEvent. Since the initializer list is empty, all members are value-initialized, and in this case, zero-initialized.

The fix landed as a separate CL: https://crrev.com/c/3081522 This is an unmodified reland. Original description: We make an undocumented assumption in {CodeSpaceWriteScope} that a single thread will only work on one module at a time. If this is violated, the thread-local {code_space_write_nesting_level_} would prevent the second module from being switched to writable. This CL adds a second thread local (in debug only) to check that if there is already a {CodeSpaceWriteScope} open that it contains the same {NativeModule} as any nested scope.

We currently print reference type indices as unsigned LEB. This will not work properly for large indices (>=64), as they will be interpreted as negative indices when read back. They may also alias with builtin types. In this CL, we fix this by defining builtin types as negative numbers. We add positive byte constants that can be used in function bodies. We adapt wasm-module-builder and tests to the above changes.

Code freeing can happen at any point in time where a GC might be triggered. Hence it's difficult to ensure that no other {CodeSpaceWriteScope} is already open at that point. The way these scope objects are implemented forbids multiple scopes for different modules though. To solve this, this CL just avoids the code zapping in {WasmCodeAllocator::FreeCode}, which is the only place that actually writes to the code space. Without this, we do not need the {CodeSpaceWriteScope} in {NativeModule::FreeCode} any more.

On Windows, the overhead of {SetPermissions} (which maps to a {VirtualAlloc} call) heavily depends on the amount of memory on which permissions are switched. Hence this CL changes permission switching to only switch the code regions that are actually needed. This will increase the number of system calls, but reduce the total size of switched memory. On a Unity benchmark, this reduced the lazy compilation time on Windows from 13.7 seconds to 3.6 seconds (3.0 seconds without write protection). On Linux, there is no measurable effect, but permission switching generally seems to have way less overhead on Linux.

BoundedPageAllocator was added in https://crrev.com/c/1226915 with lots of CHECKs. There was no special reason given for that, and it's inconsistent with the default choice for DCHECKs that we have in other parts of the code. Hence this CL degrades most of these CHECKs to DCHECKs, except for the {SetPermissions} calls which we need to execute in all configurations, and where checking the return value makes sense to detect memory bugs or OOM situations.

To consume a code cache off-thread 1. The embedder creates a CachedData object wrapping the data blob. 2. The embedder calls ScriptCompiler::StartConsumingCodeCache with the CachedData, and receives a ScriptCompiler::CodeCacheConsumeTask which takes ownership of the CachedData. 3. The embedder calls ScriptCompiler::CodeCacheConsumeTask::Run on a different thread. 4. Once this completes, the embedded passes the completed task as an optional argument into Source constructor, and calls Compile as before. This is roughly similar to how streaming compilation works, with the QoL improvement that Source owns the CodeCacheConsumeTask and therefore we can reuse the same Compile method and do the off-thread finalization behind the scenes inside Compile. On the v8::internal side, ScriptCompiler::CodeCacheConsumeTask wraps a v8::internal::BackgroundDeserializeTask, which has a Run and a Finish method. The Run creates a LocalIsolate (again, similar to BackgroundCompileTask), calls some helpers on CodeSerializer, and stores the pre-finalization result in a OffThreadDeserializeData structure. This stores Persistent Handles to the off-thread initialized SFI and a vector of Scripts needing fixing up, and it owns the PersistentHandles object which owns those Handles. Finally, the Finish method consumes this OffThreadDeserializeData structure, fixes up Scripts, moves the SFI Handle into the caller HandleScope, and that's it. Since we don't yet have the source at off-thread deserialization time, the various code cache sanity checks are done without the source hash when deserializing, and the Finish method re-does them now that the source is available.

This reverts commit fee168ce. Reason for revert: The DCHECK fails when freeing code (https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Linux64%20GC%20Stress%20-%20custom%20snapshot/38292/overview), which means that the current code is not correct. The added DCHECK makes the bots red though, so the state before this CL was still better. Original change's description: > [wasm] Check correctness of thread-local write protection > > We make an undocumented assumption in {CodeSpaceWriteScope} that a > single thread will only work on one module at a time. If this is > violated, the thread-local {code_space_write_nesting_level_} would > prevent the second module from being switched to writable. > > This CL adds a second thread local (in debug only) to check that if > there is already a {CodeSpaceWriteScope} open that it contains the same > {NativeModule} as any nested scope. > > R=jkummerow@chromium.org > > Change-Id: I43fa886d9d0fdf0e1846137dc411745fcca471fa > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3074477 > Commit-Queue: Clemens Backes <clemensb@chromium.org> > Reviewed-by: Jakob Kummerow <jkummerow@chromium.org> > Cr-Commit-Position: refs/heads/master@{#76134} TBR=jkummerow@chromium.org Change-Id: I5262b0e886f99a64452966345fc084a1ab750459 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3078360Reviewed-by:

Adds a minimum estimated size. Data suggests that estimated instruction size (+ relocation info size) is linear to bytecode array length. This CL adds a constant for this equation. The ratio remains the same. This is important, because we want to increase success rate of estimation when compiling on-heap. When off-heap, we round up the assembler buffer to 4kB, so this CL will only impact JS functions with more than 585 bytecodes, i.e, the new added constant will be negligible. Note: Relocation info (for Sparkplug) is usually so small that it is not useful to have a separate zone for this.

pthread_jit_write_protect* functions are only available on arm64 Mac, not on iOS (which also sets V8_{TARGET_,}OS_MACOSX). This CL refactors the logic to detect whether pthread_jit_write_protect and MAP_JIT are available and defines a global preprocessor macro which can subsequently be used instead of the existing complex condition.
