0x00400000
This display of memory shows part of the first subroutine
and the start of the data section.
The address of the entry point of the first subroutine is circled in red.
This corresponds to the symbolic address sub1
The data section at address 0x1000010 contains 0x00400000 the address sub1
followed by the address of the second subroutine, sub2.
Note Carefully: The top of the picture shows the contents of the text section of memory.
The contents of address 0x00400000 is the bit pattern 0x34020004.
The bottom of the picture shows the contents of the data section of memory.
The contents of address 0x1000010 is the bit pattern 0x00400000.
The assembler and loader put all strings in memory in the data section. Note that the strings of the subroutines are not stored with the code of the subroutines. The subroutines are put in memory in the text section.
The symbolic address sub1
stands for the value 0x00400000,
the entry point of the first subroutine.
This address is shown in the first red circle.
The symbolic address sub1add stands for an address
in the data section.
The value that is stored at that address
is the value 0x00400000, the entry point of the first subroutine.
This value is shown in the second red circle.
What is the address of the second subroutine? (Hint: look at the program and at the above memory dump.)
