D30V Options
------------

   These `-m' options are defined for D30V implementations:

`-mextmem'
     Link the `.text', `.data', `.bss', `.strings', `.rodata',
     `.rodata1', `.data1' sections into external memory, which starts
     at location `0x80000000'.

`-mextmemory'
     Same as the `-mextmem' switch.

`-monchip'
     Link the `.text' section into onchip text memory, which starts at
     location `0x0'.  Also link `.data', `.bss', `.strings', `.rodata',
     `.rodata1', `.data1' sections into onchip data memory, which
     starts at location `0x20000000'.

`-mno-asm-optimize'
`-masm-optimize'
     Disable (enable) passing `-O' to the assembler when optimizing.
     The assembler uses the `-O' option to automatically parallelize
     adjacent short instructions where possible.

`-mbranch-cost=N'
     Increase the internal costs of branches to N.  Higher costs means
     that the compiler will issue more instructions to avoid doing a
     branch.  The default is 2.

`-mcond-exec=N'
     Specify the maximum number of conditionally executed instructions
     that replace a branch.  The default is 4.
