Behrang contributed to the joernio/ghidra repository by implementing ARM Cortex-M stack limit support, focusing on defining MSPLIM and PSPLIM registers within the ARMv8-M processor definitions. Leveraging expertise in compiler development and embedded systems, Behrang enabled THUMB decoders for stack limit operations, ensuring these features activate only when the CORTEX macro is defined. The solution used conditional compilation to maintain build stability and prevent regressions on non-Cortex builds. Working primarily with the Sinc language and processor definition files, Behrang delivered a targeted feature that enhances the reliability and maintainability of ARM processor support within the project.
