Back-propagation of knowledge from syntax tree to C source code
Jonathan Yavner · ACM SIGPLAN Notices · 2004
To support source-code annotation, an analysis of a program must provide ( filename, line, column ) positioning tokens. The Myer parser computes such tokens for individual compilation units, then combines units to create unified annotations for files, even header files. Myer is implemented using patches to gcc, an approach that has pluses and minuses.
