The following architectural tasks need to be accomplished and should be
|
||||
fairly easy to complete:
|
||||
|
||||
|
||||
- use dynamic allocations for working memory. Scan & fix code
|
||||
for excessive stack allocations. take linux/scripts/checkpatch.pl and
|
||||
see what the worst offenders are. Example, on amd64:
|
||||
|
||||
$ objdump -d | checkpatch.pl | head -10

|
||||
- clean-up code to match style guides
|
||||
- factor code to eliminate duplicated functionality
|
||||
- rewrite code that uses casts to access 16-bit and larger types
