|-0||produce header with 16-bit magic|
|-3||produce header with 32-bit magic|
|-7||produce Seventh Edition UNIX a.out header.|
|-d||delete the header from the output file, used for MSDOS COM files. As a side effect this also includes -s as theres nowhere to put a symbol table.|
|-Cx||add file libdir-from-search/crtx.o to list of files linked|
|-D||data base address follows (in format suitable for strtoul)|
|-H||the top of heap (initial stack) address (in format suitable for strtoul)|
|-Lx||add dir name x to the head of the list of library dirs searched|
|-M||print symbols linked on stdout|
|-N||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 -z option is also included the linker can generate a QMAGIC executable.|
|-Ox||add library or object file libdir-from-search/x to list of files linked|
|-T||text base address follows (in format suitable for strtoul)|
|-i||separate I&D output|
|-lx||add library libdir-from-search/libx.a to list of files linked|
|-m||print modules linked on stdout|
|-o||output file name follows|
|-r||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 if possible.|
|-t||trace modules being looked at on stdout|
|-y||Alter the symbol tables to add label extensions so that labels with more than 8 characters can be stored in elks executables.|
|-z||produce "unmapped zero page" or "QMAGIC" executables|
The linker predefines several labels that can be imported into user programs.
__etext Standard C variable for the end of the text segment. __edata Standard C variable for the end of the initilised data. __end Standard C variable for the end of the bss area. __segoff 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 zero for impure (tiny model) executables and is adjusted for executables that dont start at offset 0 within the segment. __segXDL 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. __segXDH The top of segment Xs data area. __segXCL The bottom of segment Xs common data or unitilised data area. Each segment has both an initilised and unitilised data area. __segXCH The top of segment Xs common area. __segXSO This is the adjusted offset from segment 0 of the start of segment X in paragraphs.
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 this large.
The linker cannot deal with reverse seeks caused by org 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 -r option this is so it is compatible with pre-dev86 versions.
