Towards #https://github.com/llvm/llvm-project/issues/134809#issuecomment-2787206873 This change moves WasmSym from a static global struct to an instance owned by Ctx, allowing it to be reset cleanly between linker runs. This enables safe support for multiple invocations of wasm-ld within the same process Changes done - Converted WasmSym from a static struct to a regular struct with instance members. - Added a std::unique_ptr<WasmSym> wasmSym field inside Ctx. - Reset wasmSym in Ctx::reset() to clear state between links. - Replaced all WasmSym:: references with ctx.wasmSym->. - Removed global symbol definitions from Symbols.cpp that are no longer needed. Clearing wasmSym in ctx.reset() ensures a clean slate for each link invocation, preventing symbol leakage across runs—critical when using wasm-ld/lld as a reentrant library where global state can cause subtle, hard-to-debug errors. --------- Co-authored-by: Vassil Vassilev <v.g.vassilev@gmail.com>
