NAME
2l, 6l, 8l, kl, vl, zl - loaders
SYNOPSIS
2l [ option ... ] [ name ... ]
6l [ option ... ] [ name ... ]
8l [ option ... ] [ name ... ]
kl [ option ... ] [ name ... ]
vl [ option ... ] [ name ... ]
zl [ option ... ] [ name ... ]
DESCRIPTION
2l, 6l, 8l, kl, vl, and zl load the named files into
MC68020, i960, i386, SPARC, MIPS, and Hobbit executable
files. The files should be object files or libraries
(archives of object files) for the appropriate architecture.
Also, a name like -lext represents the library libext.a in
/$objtype/lib, where objtype is one of 68020, 960, 386,
sparc, mips, or hobbit . In practice, such options are
rarely necessary as the header files for the libraries cause
their archives to be included automatically in the load (see
2c(1)). The libraries must have tables of contents (see
rl(1)).
Normally there is an implicit -lc after the named files to
search the C library /$objtype/lib/libc.a. Also, the loader
creates an undefined symbol _main (or _mainp if profiling is
enabled) to force loading of the startup linkage from the C
library.
The loader options are:
-l (As a bare option.) Suppress the default loading
of the C library and startup linkage.
-o out Place output in file out. Default is O.out, where
O is the first letter of the loader name.
-p Insert profiling code into the executable output.
-s Strip the symbol tables from the output file.
-a Print the object code in assembly language, with
addresses.
-v Print debugging output that annotates the activi-
ties of the load.
-Hn Executable header is type n. The meaning of the
types is architecture-dependent; typically type 1

is Plan 9 boot format and type 2 is the regular
Plan 9 format, the default. These are reversed on
the MIPS. The Next boot format is 3.
-Tt The text segment starts at address t.
-Dd The data segment starts at address d.
-Rr The text segment is rounded to a multiple of r (if
r is nonzero).
The numbers in the above options can begin with `0x' or `0'
to change the default base from decimal to hexadecimal or
octal. The defaults for the values depend on the compiler
and the header type.
