  27 @table @gcctabopt
  28 @cindex @samp{-m32} option, RISC-V
  29 @cindex @samp{-m64} option, RISC-V
  30 @item -m32 | -m64
  31 Select the base ISA, either RV32 or RV64.
  32
  33 @cindex @samp{-mrvc} option, RISC-V
  34 @item -mrvc
  35 Enables the C ISA subset for compressed instructions.
  36
  37 @cindex @samp{-msoft-float} option, RISC-V
  38 @cindex @samp{-mhard-float} option, RISC-V
  39 @item -msoft-float | -mhard-float
  40 Select the floating-point ABI, hard-float has F registers while soft-float
  41 doesn't.
  42
  43 @cindex @samp{-march=RV{32,64}{G,I}{M,}{A,}{F,}{D,}{C,}} option, RISC-V
  44 @item -march=RV{32,64}{G,I}{M,}{A,}{F,}{D,}{C,}
  45 Select the base isa, as specified by ISA.  For example -march=RV32IMA.
