Pull request overview
This PR removes a set of unused helper functions (and associated declarations / dead debug code) from CoreCLR JIT sources to reduce maintenance surface and keep headers/implementation lean.
Changes:
- Removed an unused debug-only heap verifier from
PriorityQueueand the leftover commented assertions. - Removed unused LSRA helpers (range-check helpers, traversal-order stubs, reg-mask helpers, and an interval reg check).
- Removed multiple unused
Compilerhelpers (debug dump utilities, early-prop/assertion helpers, loop-hoist per-method printing, node test-data transfer, and old standalone-JIT stubs), plus an unused RISC-V emitter helper and some lowering helpers.
