| @table @gcctabopt |
| @cindex @samp{-m32} option, RISC-V |
| @cindex @samp{-m64} option, RISC-V |
| @item -m32 | -m64 |
| Select the base ISA, either RV32 or RV64. |
| |
| @cindex @samp{-mrvc} option, RISC-V |
| @item -mrvc |
| Enables the C ISA subset for compressed instructions. |
| |
| @cindex @samp{-msoft-float} option, RISC-V |
| @cindex @samp{-mhard-float} option, RISC-V |
| @item -msoft-float | -mhard-float |
| Select the floating-point ABI, hard-float has F registers while soft-float |
| doesn't. |
| |
| @cindex @samp{-march=ISA} option, RISC-V |
| @item -march=ISA |
| Select the base isa, as specified by ISA. For example -march=RV32IMA. |
