1637802 - Add markers for script compilation and execution

Status: RESOLVED FIXED

(Core :: Performance: General, task)

Description

[Denis Palmeiro [:denispal]]

We currently already have a script evaluation marker, but we can break this up into a compilation marker for main thread and off thread, and an execution marker for a bit more granularity.

Attachment: Replace ScriptEvaluation profiler marker with compilation & execution markers for bytecode, module, binast, and text sources.

Replace the existing ScriptEvaluation profiler marker with ScriptCompileMainThread, ScriptCompileOffThread, and ScriptExecution for more granularity.
