Solution Overview

Problem

The inefficiency of client-side code execution in web browsers due to dynamic programming languages, which are interpreted at runtime and not optimized until just-in-time compilation, making it difficult for developers to detect and improve JIT compiler efficiency during development.

Innovation Solution

An interactive intermediate representation (IR) viewer that allows developers to display, modify, and analyze the intermediate representation of client-side code during JIT compilation in a live environment, enabling performance analysis and optimization of both the client-side code and the JIT compiler.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If JIT compilation is used to optimize client-side code execution, then execution efficiency is improved, but the ability to detect and analyze compiler efficiency during development deteriorates

Engineering Contradiction:
Improveexecution efficiencyVSAvoidcompiler efficiency detection
Core Design Contradiction:
ProductivityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent introduces an interactive intermediate representation (IR) viewer as a mediator between the JIT compiler and the developer. This viewer displays the intermediate representation of client-side code at different compilation phases, allowing developers to inspect and analyze the compiler's work without disrupting the optimized execution path. The IR viewer serves as an intermediary tool that makes the previously invisible compilation process observable and analyzable.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If client-side code is interpreted at runtime, then flexibility and ease of execution are improved, but execution speed deteriorates

Engineering Contradiction:
Improveexecution flexibilityVSAvoidexecution speed
Core Design Contradiction:
Ease of operationVSSpeed

Solution Approach 1:

The patent implements just-in-time compilation that performs preliminary compilation of client-side code into optimized executable code during runtime before execution. The JIT compiler analyzes the intermediate representation and generates optimized machine code on-the-fly, storing it for subsequent executions. This preliminary action transforms the code from an interpreted state to a compiled state, achieving both the flexibility of runtime execution and the speed of compiled code.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If JIT compilation performs optimizations, then code efficiency is improved, but the complexity of the compilation process increases

Engineering Contradiction:
Improvecode efficiencyVSAvoidcompilation process complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the JIT compilation process into distinct phases, each handling specific optimization tasks. The compilation process is divided into: (1) parsing and intermediate representation generation, (2) optimization phases at different levels, (3) code generation, and (4) execution. The interactive IR viewer allows developers to inspect the intermediate representation at each phase boundary, making the complex compilation process more manageable and analyzable by breaking it into discrete, observable segments.

Inventive Principle:
Principle #1Segmentation

AI summary

An interactive intermediate representation (IR) viewer displays a view of the intermediate representation of client side code during a just-in-time compilation of the client side code in a live environment. The interactive IR viewer allows a developer to request the intermediate representation generated during one or more of the phases of the JIT compilation of the client side code. Modifications may be made to the intermediate representation before executable code is generated. The analysis of the intermediate representation during the live environment provides a developer with insight as to how the executable code is being compiled so that improvements may be made to improve the performance of the client side code.
