NAME

       ASLINK - companion linker for the ASxxxx assemblers.

SYNOPSIS

       aslink [options] filenames
       link-gbz80 [options] filenames
       link-z80 [options] filenames

WARNING

       The information in this man page is an extract from the full documentation of SDCC, and is limited to the meaning of the options.

       For complete and current documentation, refer to the ASxxxx Cross Assembler Documentation, available in /usr/share/doc/sdcc-doc/aslink.

DESCRIPTION

       The ASLINK is general relocating companion linker for the ASxxx assemblers.

       MCS51 family is supported by aslink.
       Z80family is supported by link-z80.
       GBZ80 (GameBoy Z80-like CPU) is supported by link-gbz80.

OPTIONS

       The linker may run in the command line mode or command file modes.  The allowed startup linker commands are:

       -c/-f  command line / command file modes

       -p/-n  enable/disable echo file.lnk input to stdout

       If command line mode is selected, all linker commands come from stdin, if the command file mode is selected the commands are input from the
       specified file (extension must be .lnk).

       After invoking the linker the valid options are:

       -i/-s  Intel Hex (file.ihx) or Motorola S19 (file.s19) image output file.

       -z     Specifies that symbol names are case sensitive.

       -m     Generate a map file (file.map). This file contains a list of the symbols (by area) with absolute addresses, sizes of  linked  areas,
	      and other linking information.

       -w     Specifies that a wide listing format be used for the map file.

       -xdq   Specifies the number radix for the map file (Hexidecimal, Decimal, or Octal).

       -u     Generate an updated listing file (file.rst) derived from the relocated addresses and data from the linker.

       fileN  Files to be linked. Files may be on the same line as the above options or on a separate line(s) one file	per line or multiple files
	      separated by spaces or tabs.

       -b area = expression (one definition per line)
	      This specifies an area base address where the expression may contain constants and/or defined symbols from the linked files.

       -g symbol = expression (one definition per line)
	      This specifies the value for the symbol where the expression may contain constants and/or defined symbols from the linked files.

       -k library directory path (one  definition  per line)
	      This specifies one possible path to an object library.  More than one path is allowed.

       -l library file specification (one  definition  per  line)
	      This specifies a possible library file.  More than one file is allowed.

       -e     or null line, terminates input to the linker.
