symbol_keep void symbol_keep(Symbol* s): Keep symbol around until symbol_term().
symbol_name Symbol* symbol_name(const(char)* name, int sclass, type* t): Create a symbol, given a name and type.
symbol_pointerType tym_t symbol_pointerType(const Symbol* s): Determine pointer type needed to access a Symbol, essentially what type an OPrelconst should get for that Symbol.
symbol_print void symbol_print(const Symbol* s): Type out symbol information.
symbol_reset void symbol_reset(Symbol* s): Reset Symbol so that it's now an "extern" to the next obj file being created.
symbol_search Symbol* symbol_search(const(char)* id): Search for symbol in sequence of symbol tables. Input: glbl !=0 if global symbol table only
symbol_searchlist Symbol* symbol_searchlist(symlist_t sl, const(char)* vident): Search list for a symbol with an identifier that matches.

symbol_tree_hydrate
void symbol_tree_hydrate(Symbol** ps): Hydrate a symbol tree.
symboltable_clean void symboltable_clean(Symbol* s): Go through symbol table preparing it to be written to a precompiled header. That means removing references to things in the .OBJ file.
symboltable_hydrate
void symboltable_hydrate(Symbol* s, Symbol** parent): Put symbol table s into parent symbol table.
symtab_realloc
Symbol** symtab_realloc(Symbol** tab, size_t symmax): Allocate/free symbol table.

Structs

Paramblock struct Paramblock: Symbol table search routine for members of structs, given that we don't know which struct it is in. Give error message if it appears more than once.
