Convert a perf trybot JSON file into a pleasing HTML page. It can read from standard input or via the --filename option. Examples: cat results.json | perf-to-html.py --title "ia32 results" perf-to-html.py -f results.json -t "ia32 results" -o results.html Options: -h, --help show this help message and exit -f FILENAME, --filename=FILENAME Specifies the filename for the JSON results rather than reading from stdin. -t TITLE, --title=TITLE Optional title of the web page. -o OUTPUT, --output=OUTPUT Write html output to this file rather than stdout.

The current GC idle time handling heuristics are getting too complicated. Moreover, with longer idle time we are getting more full garbage collections. This CL shrinks the idle round window and reduces complexity in the case where we cause a full garbage collection.

Revert of Reland "Filter invalid slots out from the SlotsBuffer after marking." (patchset #2 id:2 of https://codereview.chromium.org/1032833002/) Reason for revert: Reverting risky GC changes that block v8 roll. Original issue's description: > Reland "Filter invalid slots out from the SlotsBuffer after marking." > > > There are two reasons that could cause invalid slots appearance in SlotsBuffer: > > 1) If GC trims "tail" of an array for which it has already recorded a slots and then migrate another object to the "tail". > > 2) Tagged slot could become a double slot after migrating of an object to another map with "shifted" fields (for example as a result of generalizing immutable data property to a data field). > > > This CL also adds useful machinery that helps triggering incremental write barriers. > > > BUG=chromium:454297 > > LOG=Y > > NOTRY=true > > Committed: https://crrev.com/f86aadd1d45c756467dff8e08a055b462d7a060b > Cr-Commit-Position: refs/heads/master@{#27433} TBR=machenbach@chromium.org,ulan@chromium.org NOPRESUBMIT=true NOTREECHECKS=true NOTRY=true Review URL: https://codereview.chromium.org/1041593002 Cr-Commit-Position: refs/heads/master@{#27491}

The aforementioned predicate reported a JSFunction that was marked for optimization as already compiled. This in turn also prevented us from being aggressive about FLAG_always_opt treatment.

port 38a719f9 (r27440) original commit message: This switches full-codegen to no longer push and pop StackHandler markers onto the operand stack, but relies on a range-based handler table instead. We only use StackHandlers in JSEntryStubs to mark the transition from C to JS code. Note that this makes deoptimization and OSR from within any try-block work out of the box, makes the non-exception paths faster and should overall be neutral on the memory footprint (pros). On the other hand it makes the exception paths slower and actually throwing and exception more expensive (cons).

Before this patch the embedder could assign timestamp to the last interval after calling GetHeapStats. This would be slightly different from the timstamps assigned by v8 internally and written into heap snapshot. This patch allow to avoid this small discrepancy by returning timestamp along with last heap stats update.

port 6689cc27 (r27377) original commit message: Handlers should be in charge of this work. The change uncovered a bug in vector-ics related to keyed loads into strings. It's important for StringCharCodeAtGenerator, a helper used in full code and in LoadIndexedStringStub (a handler) to protect the vector and slot registers when it makes a runtime call to convert a HeapNumber to a Smi. It's still possible for the handler to MISS after this call, perhaps due to out of bounds access. In that case, the vector and slot registers need to be delivered safely to the MISS handler.
