Pull request overview
This PR removes the obsolete POPFRAMES stackwalk option and all code guarded by STACKWALKER_MAY_POP_FRAMES preprocessor directives. These became obsolete after the removal of FEATURE_EH_FUNCLETS. The changes are purely code deletion with no functional impact on remaining code paths.
Key changes:
- Removed the
POPFRAMESconstant definition from the stackwalk flags - Removed all
STACKWALKER_MAY_POP_FRAMESconditional compilation blocks - Simplified control flow by removing POPFRAMES-specific if-else branches
