Overlay generator

List of support files

• function_sizes.nm: Required by overlay_generator, generated from object files using the command line:

nm --size-sort *.o > function_sizes.nm

• region_sizes_file.dat: Used by script to describe what sizes of scratchpad memory to use, the contents are three space delimited numbers given in bytes: start_size stop_size step_size
• root_node.configure_overlay_generator: Used by script to describe the root function for the project folder
• object_filename.cfg: Needed by overlay generator to determine GCCFG of project code, one file is generated for each object file by gcc when the -fdump-tree-cfg switch is given in CFLAGS

List of files generated by overlay_generator

• common_ancestors.common: Generated by overlay_generator to record common ancestor information so that it need not be recalculated later
• included_functions.funcs: List of functions included in overlay, generated by overlay_generator
• graph_[1-8].dot and graph_[1-8].ps: dotty and postscript representations of GCCFG at various stages of construction, graphs follwing graph_4 each represent an overlay algorithm
