Handler Implementation Notes
Current RenesasHandler Issues
- HashSet Usage: Uses
new HashSet<>()instead ofSet.of()- mutable set returned - Package Extraction Logic: Simple algorithm finds last digit and takes everything after it
- Works for patterns like
R5F51303ADFN->DFN - May fail for complex suffixes with version numbers
- Works for patterns like
Pattern Registration
The handler registers patterns for:
- RX Series:
^R5F[0-9]+.* - RL78 Series:
^R5F1[0-9]+.* - RH850 Series:
^R7F[0-9]+.* - RA Series:
^R7FA[0-9]+.* - R8C/RE Series:
^R8C[0-9]+.* - Memory:
^R1EX[0-9]+.*,^R1LV[0-9]+.*
Overlapping Patterns Issue
Note: RL78 pattern ^R5F1[0-9]+.* is a subset of RX pattern ^R5F[0-9]+.*
This means RL78 parts will match both patterns.
