`ld' and the Intel 960 family
=============================

   You can use the `-AARCHITECTURE' command line option to specify one
of the two-letter names identifying members of the 960 family; the
option specifies the desired output target, and warns of any
incompatible instructions in the input files.  It also modifies the
linker's search strategy for archive libraries, to support the use of
libraries specific to each particular architecture, by including in the
search loop names suffixed with the string identifying the architecture.

   For example, if your `ld' command line included `-ACA' as well as
`-ltry', the linker would look (in its built-in search paths, and in
any paths you specify with `-L') for a library with the names

     try
     libtry.a
     tryca
     libtryca.a

The first two possibilities would be considered in any event; the last
two are due to the use of `-ACA'.

   You can meaningfully use `-A' more than once on a command line, since
the 960 architecture family allows combination of target architectures;
each use will add another pair of name variants to search for when `-l'
specifies a library.

   `ld' supports the `--relax' option for the i960 family.  If you
specify `--relax', `ld' finds all `balx' and `calx' instructions whose
targets are within 24 bits, and turns them into 24-bit program-counter
relative `bal' and `cal' instructions, respectively.  `ld' also turns
`cal' instructions into `bal' instructions when it determines that the
target subroutine is a leaf routine (that is, the target subroutine does
not itself call any subroutines).
