Stabs symbols are used to hold debugging information. In this case, the next values printed are the stabs other field, the stabs desc field, and the stab type. "-" The symbol is a stabs symbol in an a.out object file. On some systems, uppercase indicates that a default value has been specified. When a weak undefined symbol is linked and the symbol is not defined, the value of the symbol is determined in a system-specific manner without error. When a weak defined symbol is linked with a normal defined symbol, the normal defined symbol is used with no error. "W" "w" The symbol is a weak symbol that has not been specifically tagged as a weak object symbol. When a weak undefined symbol is linked and the symbol is not defined, the value of the weak symbol becomes zero with no error. For such a symbol the dynamic linker will make sure that in the entire process there is just one symbol with this name and type in use. This is a GNU extension to the standard set of ELF symbol bindings. "u" The symbol is a unique global symbol. "T" "t" The symbol is in the text (code) section. "S" "s" The symbol is in an uninitialized data section for small objects. "R" "r" The symbol is in a read only data section. "p" The symbols is in a stack unwind section. The runtime execution will then return the value to be used in the relocation.
It indicates a symbol which if referenced by a relocation does not evaluate to its address, but instead must be invoked at runtime. This is a GNU extension to the standard set of ELF symbol types. For ELF format files this indicates that the symbol is an indirect function. "i" For PE format files this indicates that the symbol is in a section specific to the implementation of DLLs. Some object file formats permit more efficient access to small data objects, such as a global int variable as opposed to a large global array.
"G" "g" The symbol is in an initialized data section for small objects. "D" "d" The symbol is in the initialized data section. If the symbol is defined anywhere, the common symbols are treated as undefined references. When linking, multiple common symbols may appear with the same name. "B" "b" The symbol is in the uninitialized data section (known as BSS ). "A" The symbol's value is absolute, and will not be changed by further linking. If lowercase, the symbol is local if uppercase, the symbol is global (external).
