The following table lists all availiable RISC-V specific options

@c man begin OPTIONS
@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.
