Speculative Compilation for Incremental Source Code Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional compilation processes are inefficient as they require programmers to wait until the entire source code is entered before compiling, leading to underutilization of idle time during editing and debugging, and existing solutions like interpreted languages or pre-compiled header files either lose optimization efficiency or require significant storage.
Innovation Solution
A method and apparatus for speculative compilation, where a computing apparatus with a text editor and compiler compiles a portion of the source code during editing by identifying waypoints and invoking the compiler to optimize and process the code incrementally, reducing the need for full compilation during editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional compilation is performed only after complete source code entry, then the compiler can process the entire program for optimization, but the idle time during editing is wasted and development time increases
Solution Approach 1:
The system performs preliminary compilation actions during the editing phase by identifying waypoints in the source code and compiling portions of the program before the user finishes editing. This preliminary action utilizes idle time during editing and debugging to perform compilation work that would otherwise occur later, thereby reducing total development time without compromising final compilation quality
Solution Approach 2:
The compilation process is segmented into multiple portions based on identified waypoints in the source code. Instead of compiling the entire program at once or waiting for completion, the system divides the compilation task into manageable segments that can be processed incrementally during editing, improving overall compilation efficiency while maintaining optimization quality
2Loss of time
If interpreted languages are used for incremental compilation, then development time is reduced, but optimization efficiency is lost
Solution Approach 1:
The system changes the parameter of compilation timing from 'after complete editing' to 'during editing at identified waypoints'. This parameter change enables the use of a proper compiler rather than an interpreter, maintaining optimization efficiency while reducing development time through incremental compilation of code portions
3Productivity
If pre-compiled header files are used to speed up compilation, then compilation time is reduced, but significant storage space is required
Solution Approach 1:
Instead of pre-compiling all header files (excessive action requiring significant storage), the system performs partial compilation only of the portions of code up to identified waypoints during editing. This partial action provides compilation speed benefits without requiring the substantial storage space needed for full pre-compilation of all headers

AI summary
The invention is a method and apparatus for use in developing a program. More particularly, a method and apparatus for compiling a source code program during editing of the same is disclosed, where editing can be initial entry or modification subsequent to initial entry. The method comprises compiling at least a portion of a source code program defined by a waypoint during the editing of the source code program. In other aspects, the invention includes a program storage medium encoded with instructions that, when executed, perform this method and a computer programmed to perform this method. The apparatus includes a computing apparatus, comprising a text editor through which a source code program may be entered; and a compiler that may compile the source code program. The control block is capable of determining at least one waypoint in the source code program and invoking the compiler to compile the source code program up to the waypoint.
