3.17.30 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.
