Intel 960 Options
-----------------

   These `-m' options are defined for the Intel 960 implementations:

`-mCPU TYPE'
     Assume the defaults for the machine type CPU TYPE for some of the
     other options, including instruction scheduling, floating point
     support, and addressing modes.  The choices for CPU TYPE are `ka',
     `kb', `mc', `ca', `cf', `sa', and `sb'.  The default is `kb'.

`-mnumerics'
`-msoft-float'
     The `-mnumerics' option indicates that the processor does support
     floating-point instructions.  The `-msoft-float' option indicates
     that floating-point support should not be assumed.

`-mleaf-procedures'
`-mno-leaf-procedures'
     Do (or do not) attempt to alter leaf procedures to be callable
     with the `bal' instruction as well as `call'.  This will result in
     more efficient code for explicit calls when the `bal' instruction
     can be substituted by the assembler or linker, but less efficient
     code in other cases, such as calls via function pointers, or using
     a linker that doesn't support this optimization.

`-mtail-call'
`-mno-tail-call'
     Do (or do not) make additional attempts (beyond those of the
     machine-independent portions of the compiler) to optimize
     tail-recursive calls into branches.  You may not want to do this
     because the detection of cases where this is not valid is not
     totally complete.  The default is `-mno-tail-call'.

`-mcomplex-addr'
`-mno-complex-addr'
     Assume (or do not assume) that the use of a complex addressing
     mode is a win on this implementation of the i960.  Complex
     addressing modes may not be worthwhile on the K-series, but they
     definitely are on the C-series.  The default is currently
     `-mcomplex-addr' for all processors except the CB and CC.

`-mcode-align'
`-mno-code-align'
     Align code to 8-byte boundaries for faster fetching (or don't
     bother).  Currently turned on by default for C-series
     implementations only.

`-mic-compat'
`-mic2.0-compat'
`-mic3.0-compat'
     Enable compatibility with iC960 v2.0 or v3.0.

`-masm-compat'
`-mintel-asm'
     Enable compatibility with the iC960 assembler.

`-mstrict-align'
`-mno-strict-align'
     Do not permit (do permit) unaligned accesses.

`-mold-align'
     Enable structure-alignment compatibility with Intel's gcc release
     version 1.3 (based on gcc 1.37).  Currently this is buggy in that
     `#pragma align 1' is always assumed as well, and cannot be turned
     off.
