Method for tracking changes in source locations in a compiler

Abstract

The disclosed method creates a source object for each source language element parsed by the compiler and associates each such created source object with objects created from source language elements to produce source-mapped objects. Next, the source-mapped objects are transformed into corresponding machine-instruction objects and a binary file of the machine-instruction objects is created by: i) adjusting a source data object to a source object associated with a machine instruction object, thereby identifying a lowest level of inlining where the call history of the source object differs from the call history of the previous source object to which the source data object was adjusted; ii) if the source data object identifies no differences from the previous source object, then continuing at step i) for the next machine instruction; and, iii) for each level of the call history beginning with the level returned in the preceding step and continuing through the last level, putting information obtained from the source data object in a source table stored in the binary file.
