This linker understands only the object files produced by the as86 assembler,
it can link them into either an impure or a separate I&D executable.
The linking defaults are everything off or none except for
and the output file is
a standard library location defined in the linker.
produce header with 16-bit magic
produce header with 32-bit magic
delete the header from the output file, used for MSDOS COM files. As a side
effect this also includes -s as there's nowhere to put a symbol table.
add file libdir-from-search/crtx.o to list of files linked
data base address follows (in format suitable for strtoul)
the top of heap (initial stack) address (in format suitable for strtoul)
add dir name x to the head of the list of library dirs searched
print symbols linked on stdout
Create a native Linux OMAGIC output file. If the contents are i386 code the
binary can be either linked by GCC or executed by linux. If the
option is also included the linker can generate a QMAGIC executable.
add library or object file libdir-from-search/x to list of files linked
text base address follows (in format suitable for strtoul)
separate I&D output
add library libdir-from-search/libx.a to list of files linked
print modules linked on stdout
output file name follows
Generate a relocatable object from one source object, if the linker is
given the -N option also the output format will be the hosts native format
trace modules being looked at on stdout
Alter the symbol tables to add label 'extensions' so that labels with
more than 8 characters can be stored in elks executables.
produce "unmapped zero page" or "QMAGIC" executables
All the options not taking an argument may be turned off by following the
option letter by a '-', as for cc1.
The linker predefines several labels that can be imported into user programs.
Standard C variable for the end of the text segment.
Standard C variable for the end of the initilised data.
Standard C variable for the end of the bss area.
The offset within the executable file between the start of the text segment
and the start of the data segment in 16 byte 'paragraphs'. Note this is
for impure (tiny model) executables and is adjusted for executables that
don't start at offset 0 within the segment.
The lowest address with data in segment 'X'. (eg __seg0DL is for segment zero
or the text segment, __seg3DL is for the data segment)
The value 'X' is a hex digit.
The top of segment 'X's data area.
The bottom of segment 'X's 'common data' or unitilised data area. Each
segment has both an initilised and unitilised data area.
The top of segment 'X's common area.
This is the adjusted offset from segment 0 of the start of segment 'X'
The 6809 version does not support -i.
The previous versions of the linker could produce an 8086 executable with
segments of a size >64k, now only i386 executables may have segments
The linker cannot deal with reverse seeks caused by
instructions in the object file. Unlike previous versions the current one
traps the error rather than trying to fill up the hard disk.
The linker produces a broken a.out object file if given one input and the
option this is so it is compatible with pre-dev86 versions.
