OpenRISC

These options are defined for OpenRISC:

       -mboard=name
           Configure a board specific runtime.  This will be passed to
           the linker for newlib board library linking.  The default is
           "or1ksim".

       -mnewlib
           For compatibility, it's always newlib for elf now.

       -mhard-div
           Generate code for hardware which supports divide
           instructions.  This is the default.

       -mhard-mul
           Generate code for hardware which supports multiply
           instructions.  This is the default.

       -mcmov
           Generate code for hardware which supports the conditional
           move ("l.cmov") instruction.

       -mror
           Generate code for hardware which supports rotate right
           instructions.

       -msext
           Generate code for hardware which supports sign-extension
           instructions.

       -msfimm
           Generate code for hardware which supports set flag immediate
           ("l.sf*i") instructions.

       -mshftimm
           Generate code for hardware which supports shift immediate
           related instructions (i.e. "l.srai", "l.srli", "l.slli",
           "1.rori").  Note, to enable generation of the "l.rori"
           instruction the -mror flag must also be specified.

       -msoft-div
           Generate code for hardware which requires divide instruction
           emulation.

       -msoft-mul
           Generate code for hardware which requires multiply
           instruction emulation.
