Dependent code deopts were only printed with --trace-deopt-verbose earlier. These just print one line and are helpful with --trace-deopt. If we don't print these with --trace-deopt, it appears as if we are optimizing without any deopts in between which is a bit confusing.

This cl extends profview to 1. Show Turboprop ticks in a different color in timeline panel 2. In summary panel, show Turboprop optimizations and TurboFan optimizations as two different entries 3. Fix deopts in summary panel after the rename to deopts 4. Also show information about bailouts (happen only with Turboprop) Bug: v8:9684 Change-Id: I028b12a55741c789ecc1d212d1517a57496379dc Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2573477 Commit-Queue: Mythri Alle <mythria@chromium.org> Reviewed-by:

VerifyNewSpaceTop() assumes that original_top_ and allocation_info_.start() always match. PublishPendingAllocations() violates this invariant by only updating original_top_ in the NewSpace. Fix this by using MarkLabStartInitialized() for NewSpace. Alternatively we could loosen the DCHECK in VerifyNewSpaceTop(). The fix doesn't matter too much since Ulan's LAB refactoring will get rid of that code anyways.

Improve the performance of gcmole by * Precompiling the regexes in GCSuspectsCollector.Resolve * Merging those regexes into a single regex, using '|' * Changing multiprocess clang plugin invocation to threaded (running the plugin releases the GIL so this can efficiently thread). This uses a simple worker pool with a single work queue. * Change clang plugin invocation loop to yield after each invocation. This pipelines the dump-callees plugin and GCSuspectsCollector Parse/Resolve, so that the parse can happen while waiting for other callee dumps to finish.

We currently do not report a script ID for wasm code, i.e. the script id is 0. We cannot just print the script ID itself, as it is considered unstable. Thus this CL only makes us print whether it is set or not. In a follow-up CL where we fix setting script IDs for wasm code events the output will change.

Port String::Flatten to Torque (using a fast C call for the non-allocating part) and provide fast and easy access to sequential string data in Torque: GetStringData() flattens if necessary and computes slices that allow direct access. Applications: String.prototype.replaceAll, String.prototype.endsWith, and String.prototype.beginsWith now use GetStringData() and direct slice access instead of the slow StringCharCodeAt and they no longer bail out to the runtime for flattening. Drive-by changes: - Expose String instance type bits as bitfields and enums in Torque. - Fix method lookup in Torque to include superclass methods. - Use char8 and char16 types in more places. - Allow fast C calls with void return type. - Add Torque macros to create subslices. - Add no-GC scopes to runtime functions loading external string data.

Some extract lane and replace lane opcodes overlap with the ones used for load lane, with a different addressing mode. Merge those cases together and delete unused opcodes. Drive by clean-up to rename kF32x4ReplaceLane to kIA32Insertps to follow the naming convetion (kIA32 prefix) and also make it more general if in the future we use insertps for other purposes.

First step towards the new exception handling proposal: https://github.com/WebAssembly/exception-handling/issues/125 This is essentially a revert of: "[wasm] Switch to new 'catch' and 'br_on_exn' proposal." The changes are: - "catch" instruction takes a tag immediate, - "rethrow" instruction takes a label immediate, - Add "catch_all" instruction, - Remove "br_on_exn" instruction, - Do not push exceptions on the stack, only the encoded values R=clemensb@chromium.org CC=aheejin@chromium.org Bug: v8:8091 Change-Id: Iea4d8d5a5d3ad50693f645e93c13e8de117aa884 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2484514 Commit-Queue: Thibaud Michaud <thibaudm@chromium.org> Reviewed-by:
