Remove all macros related to getting and setting some symbol value:
#define SYMBOL_VALUE(symbol) (symbol)->value.ivalue
#define SYMBOL_VALUE_ADDRESS(symbol) \
#define SET_SYMBOL_VALUE_ADDRESS(symbol, new_value) \
#define SYMBOL_VALUE_BYTES(symbol) (symbol)->value.bytes
#define SYMBOL_VALUE_COMMON_BLOCK(symbol) (symbol)->value.common_block
#define SYMBOL_BLOCK_VALUE(symbol) (symbol)->value.block
#define SYMBOL_VALUE_CHAIN(symbol) (symbol)->value.chain
#define MSYMBOL_VALUE(symbol) (symbol)->value.ivalue
#define MSYMBOL_VALUE_RAW_ADDRESS(symbol) ((symbol)->value.address + 0)
#define MSYMBOL_VALUE_ADDRESS(objfile, symbol) \
#define BMSYMBOL_VALUE_ADDRESS(symbol) \
#define SET_MSYMBOL_VALUE_ADDRESS(symbol, new_value) \
#define MSYMBOL_VALUE_BYTES(symbol) (symbol)->value.bytes
#define MSYMBOL_BLOCK_VALUE(symbol) (symbol)->value.block
Replace them with equivalent methods on the appropriate objects.
