Table 1.19: Storage Class and Value
If a symbol has storage class
C_FILE
, the value of the symbol is the symbol
table entry index of the next
.file
symbol. The
.file
entries form a one-way linked
list within the symbol table. The value of the last
.file
symbol table entry is the
index of the first global symbol.
Relocatable symbols have a value that is equal to the virtual address of the
symbol. When a section is relocated by the linker, the values of the section's
relocatable symbols change.
