3.2.5 Symbol Information

When -show=symbol is specified, the addresses, sizes, and types of externally defined symbols or static internally defined symbols are output in the order of address. When -show=reference is specified, the symbol reference counts and optimization information are also output. The following figure shows an example of symbol information output.

Description

(1)

Section name

(2)

File name

(3)

Start address of a section included in the file indicated by (2) above

(4)

End address of a section included in the file indicated by (2) above

(5)

Section size of a section included in the file indicated by (2) above

(6)

Symbol name

(7)

Symbol address

**OVER** being displayed here indicates that the address exceeded the range that can be expressed by 32 bits.

(8)

Symbol size

(9)

Symbol type as shown below

Data type:

func: Function name

data: Variable name

entry: Entry function name

none:Undefined (label, assembler symbol)

Declaration type

g: External definition

l: Internal definition

(10)

Symbol reference count only when -show=reference is specified. * is output when show=reference is not specified.

(11)

Optimization information as shown below.

ch: Symbol modified by optimization

cr: Symbol created by optimization

mv: Symbol moved by optimization

When the -show=struct option is specified, the addresses for the structure and union members that are defined in the source file for which the -debug option was specified at compilation are output. The output example of the symbol information is shown below.
