Patch to add d30v option documentation

[Michael Meissner <meissner at redhat dot com>]

When I added the D30V compiler to the FSF, I forgot to copy in the
option documentation.  This patch fixes that:

2000-07-24  Michael Meissner  <meissner@redhat.com>

	* invoke.texi (D30V Options): Add d30v options.

+ @node D30V Options
+ @subsection D30V Options
+ @cindex D30V Options
+ 
+ These @samp{-m} options are defined for D30V implementations:
+ 
+ @table @code
+ @item -mextmem
+ Link the @samp{.text}, @samp{.data}, @samp{.bss}, @samp{.strings},
+ @samp{.rodata}, @samp{.rodata1}, @samp{.data1} sections into external
+ memory, which starts at location @code{0x80000000}.
+ 
+ @item -mextmemory
+ Same as the @samp{-mextmem} switch.
+ 
+ @item -monchip
+ Link the @samp{.text} section into onchip text memory, which starts at
+ location @code{0x0}.  Also link @samp{.data}, @samp{.bss},
+ @samp{.strings}, @samp{.rodata}, @samp{.rodata1}, @samp{.data1} sections
+ into onchip data memory, which starts at location @code{0x20000000}.
+ 
+ @item -mno-asm-optimize
+ @itemx -masm-optimize
+ Disable (enable) passing @samp{-O} to the assembler when optimizing.
+ The assembler uses the @samp{-O} option to automatically parallelize
+ adjacent short instructions where possible.
+ 
+ @item -mbranch-cost=@var{n}
+ Increase the internal costs of branches to @var{n}.  Higher costs means
+ that the compiler will issue more instructions to avoid doing a branch.
+ The default is 2.
+ 
+ @item -mcond-exec=@var{n}
+ Specify the maximum number of conditionally executed instructions that
+ replace a branch.  The default is 4.
+ @end table
