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.
The ASxxxx assemblers are a series of microprocessor assemblers. Each
assembler has a device specific section.
MCS51 family is supported by asx8051.
Z80family is supported by as-z80.
GBZ80 (GameBoy Z80-like CPU) is supported by as-gbz80.
The ASxxxx assemblers are command line oriented. The PC assemblers are
started with the appropriate option(s) and file(s) to assemble
following the assembler name.
-d decimal listing.
-q octal listing.
-x hex listing (default)
The listing radix affects the .lst, .rel, and .sym files.
-j add line number and debug information to file.
-g undefined symbols made global.
-a all user symbols made global.
-l create list output file1.lst.
-o create object output file1.rel.
-s create symbol output file1.sym.
-p disable listing pagination.
-w wide listing format for symbol table.
-z enable case sensitivity for symbols.
-f flag relocatable references by ‘ in the listing file.
-ff flag relocatable reference by mode in the listing file.
The file name for the .lst, .rel, and .sym files is the first file name
specified in the command line. All output files are ascii text files
which may be edited, copied, etc. The output files are the
concatenation of all the input files, if files are to be assembled
independently invoke the assembler for each file.
The .rel file contains a radix directive so that the linker will use
the proper conversion for this file. Linked files may have different
If the list (l) option is specified without the symbol table (s)
option, the symbol table is placed at the end of the listing file.
