The CL refactors the following builtins: String.prototype.startsWith String.prototype.endsWith to use ClampToIndexRange(x, len) instead of NumberMin(NumberMax(x, 0), len).

Clemens Backes authored
The same change on the {CopyChars} function gave an unexpected 10-20% speedup on microbenchmarks across platforms (ia32, x64, Atom_x64). This CL explores whether a similar change generally speeds up {MemCopy} and {MemMove} (only on x64 for now). If this is the case, we might be able to carefully extend the same pattern to other platforms and remove custom assembly implementations without too much regression.

These counters track how often the slow path of these two builtins is hit. Exec is very permissive, its fast-path check doesn't look at the regexp prototype at all. Replace is strict; any change on the prototype will trigger the slow path.

Port 3cad6bf5 Original Commit Message: This is a reland of c7c47c68. This makes TSAN happy in addition to: Previously I presumed that the context read from a frame in the profiler was a valid context. Turns out that on non-intel we're not guaranteed that the frame is properly set up. In the case we looked at, the profiler took a sample right before writing the frame marker indicating a builtin frame, causing the "context" pointer from that frame to be a bytecode array. Since we'll read random garbage on the stack as a possible context pointer, I made the code reading the native context from it a little more defensive. Bug: v8:9860 Tbr: ulan@chromium.org, neis@chromium.org, ishell@chromium.org Original change's description: > [runtime] Move Context::native_context to the map > > Remove the native context slot from contexts by making context maps > native-context-specific. Now we require 2 loads to go from a context to the > native context, but we have 1 field fewer to store when creating contexts. > > Change-Id: I3c0d7c50c94060c4129db684f46a567de6f30e8d > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1859629 > Commit-Queue: Toon Verwaest <verwaest@chromium.org> > Reviewed-by: Igor Sheludko <ishell@chromium.org> > Reviewed-by: Peter Marshall <petermarshall@chromium.org> > Reviewed-by: Maya Lekova <mslekova@chromium.org> > Reviewed-by: Georg Neis <neis@chromium.org> > Reviewed-by: Ulan Degenbaev <ulan@chromium.org> > Reviewed-by: Toon Verwaest <verwaest@chromium.org> > Cr-Commit-Position: refs/heads/master@{#64296} R=xwafish@gmail.com Change-Id: I6496a8c5be8cbabf48cddc2d59111410f31eb75f Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1868774 Auto-Submit: Mu Tao <pamilty@gmail.com> Commit-Queue: Bill Budge <bbudge@chromium.org> Reviewed-by:

Currently, RegExpResult builds match indices lazily using data stored in hidden internal fields on the result object itself. Unfortunately, if an internal field is deleted, it can cause these hidden fields to migrate to a dictionary, making indexed lookup unsafe. This CL forces slow but safe lookup for these fields when lazily building indices.

The new regexp_backtracks / V8.RegExpBacktracks counter tracks the number of backtracks performed per regexp execution. The results can help us prioritize related work. Note that we only count backtracks in the interpreter. Jitted code is ignored. With our current regexp tiering strategy, that means we count backtracks only in the first execution of each regexp.
