Understanding LLD's SymbolTable's use of CachedHashStringRef
...or "foo" twice [1]. Instead, once you've constructed a CachedHashStringRef from a StringRef, you can pass that around instead of the StringRef to avoid needing to recompute the hash for it.
LLD COFF's symbol table structure is a DenseMap<CachedHashStringRef, Symbol *> named symMap [2]. (ELF's is similar, except it maps to a vector index instead of a Symbol * directly for symbol order determinism reasons.) The only accesses to symMap are either iterating over its values or doing a lookup. In the two cases where a map lookup is done [3][4], the input to the function doing...
