Relocatable assembly code help

[kosthala]

Hello,

In my assembly code i have define two relocatable code segments (DEFAULT_ROM and NVREG), but
the segment NVREG doesn't appear in the .map file.
This is my sample code:

Code:

INCLUDE "MC9S08QG8.inc"    XDEF    nvDEFAULT_ROM  SECTIONnv  lda    #16    sta    PTADNVREG    SECTIONxxx lda    #67    sta    PTBD    end

 The corresponding .prm file is like this:

Code:

/* This is a linker parameter file for the mc9s08qg8 */NAMES END /* CodeWarrior will pass all the needed files to the linker by command line. But here you may add your own files too. */SEGMENTS /* Here all RAM/ROM areas of the device are listed. Used in PLACEMENT below. */    Z_RAM                    =  READ_WRITE   0x0060 TO 0x00FF;    RAM                      =  READ_WRITE   0x0100 TO 0x025F;    ROM                      =  READ_ONLY    0xE000 TO 0xE0FF;    ROM1                     =  READ_ONLY    0xE100 TO 0xE200; /* INTVECTS                 =  READ_ONLY    0xFFD0 TO 0xFFFF; Reserved for Interrupt Vectors */ENDPLACEMENT /* Here all predefined and user segments are placed into the SEGMENTS defined above. */    DEFAULT_RAM                         /* non-zero page variables */                                        INTO  RAM;    _PRESTART,                          /* startup code */    STARTUP,                            /* startup data structures */    ROM_VAR,                            /* constant variables */    STRINGS,                            /* string literals */    VIRTUAL_TABLE_SEGMENT,              /* C++ virtual table segment */    DEFAULT_ROM,    COPY                                /* copy down information: how to initialize variables */                                        INTO  ROM; /* ,ROM1: To use "ROM1" as well, pass the option -OnB=b to the compiler */ NVREG   INTO  ROM1;    _DATA_ZEROPAGE,                     /* zero page variables */    MY_ZEROPAGE                         INTO  Z_RAM;ENDSTACKSIZE 0x50INIT nvVECTOR 0  nv /* Reset vector: this is the default entry point for an application. */

And this is the .map file.

Code:

As you can see, the nv label exists in the .map file, while the label xxx which is in the second section (NVREG) doesn't exist. Do i miss something here?
