Directives
BL51 Linker directives are entered on the command line after the output file. Multiple directives must be separated by at least one empty space. Each directive may be entered only once on the command line. If a directive is entered twice, the linker generates an error.
The following table describes all BL51 Linker directives.
| Directive | Description |
|---|---|
| BANKx | Specifies the code bank in which to locate the specified segment. |
| BANKAREA | Specifies the address range where code banks are located. |
| BIT |
Locates BIT segments. |
| CODE |
Locates CODE segments. |
| DATA |
Locates DATA segments. |
| DISABLEWARNING | Disables generation of specified warning numbers. |
| IBANKING | Uses the on-chip code banking hardware of the Mentor M8051EW core, the Infineon SDA30C16x/26x, and the Micronas SDA555x. |
| IDATA |
Locates IDATA segments. |
| IXREF | Enables cross reference details in the listing file. |
| NAME | Specifies the module name of the output file. |
| NOAJMP | Avoids AJMP instructions in bank switch code. |
| NOAMAKE | Excludes AMAKE information from the object file. |
| NODEBUGLINES | Excludes line number information from the output object file. |
| NODEBUGPUBLICS | Excludes public symbol information from the output object file. |
| NODEBUGSYMBOLS | Excludes local symbol information from the output object file. |
| NODEFAULTLIBRARY | Disables automatic inclusion of run-time library routines. |
| NOINDIRECTCALL | Disables bank switching code for indirectly called functions. |
| NOJMPTAB | Disables generation of the code banking jump table. |
| NOLINES | Excludes line number information from the listing file and object file. |
| NOMAP | Excludes the memory map from the listing file. |
| NOOVERLAY | Disables data segment overlaying. |
| NOPRINT | Disables generation of the listing (MAP) file. |
| NOPUBLICS | Excludes public symbols from the listing file and object file. |
| NOSORTSIZE | Disables sorting sections by size prior to locating. |
| NOSYMBOLS | Excludes local symbols from the listing file and object file. |
| OVERLAY | Modifies the call tree for overlaying of local bit and data segments. |
| PAGELENGTH | Specifies the number of lines on a page in the listing file. |
| PAGEWIDTH | Specifies the number of characters on a line in the listing file. |
| PDATA |
Locates PDATA segments. |
| PRECEDE | Locates segments in DATA memory prior to other relocatable BIT, DATA, and IDATA segments. |
| Specifies the name of the listing file. | |
| RAMSIZE | Specifies the number of bytes of DATA and IDATA. |
| RECURSIONS | Specifies the maximum number of recursive calls detected before link failure. |
| REGFILE | Specifies the name of the register definition file for global register coloring. |
| RTX51 | Specifies that the RTX51 Real-Time Kernel is used. |
| RTX51TINY | Specifies that the RTX51 Tiny Real-Time Kernel is used. |
| SPEEDOVL | Ignores references from constant segments to program segments during overlay analysis. |
| STACK | Locates segments in the uppermost IDATA memory space. |
| XDATA |
Locates XDATA segments. |
