6.3.2 Image$$ execution region symbols
The linker generates Image$$ symbols for every execution region present in the image.
The following table shows the symbols that the linker generates for every execution region
present in the image. All the symbols refer to execution addresses after the C library is
initialized.
Table 6-1 Image$$ execution region symbols
| Symbol | Description |
|---|---|
Image$$ |
Execution address of the region. |
Image$$ |
Execution region length in bytes excluding ZI length. |
Image$$ |
Address of the byte beyond the end of the non-ZI part of the execution region. |
Image$$ |
Execution address of the RO output section in this region. |
Image$$ |
Length of the RO output section in bytes. |
Image$$ |
Address of the byte beyond the end of the RO output section in the execution region. |
Image$$ |
Execution address of the RW output section in this region. |
Image$$ |
Length of the RW output section in bytes. |
Image$$ |
Address of the byte beyond the end of the RW output section in the execution region. |
Image$$ |
Execution address of the XO output section in this region. |
Image$$ |
Length of the XO output section in bytes. |
Image$$ |
Address of the byte beyond the end of the XO output section in the execution region. |
Image$$ |
Execution address of the ZI output section in this region. |
Image$$ |
Length of the ZI output section in bytes. |
Image$$ |
Address of the byte beyond the end of the ZI output section in the execution region. |
