As application complexity increases, it is hard to imagine how development could keep up with demand without increasingly sophisticated compilers to translate our high-level ideas to low-level machine code. But as compilers work to squeeze more and more ... WebOct 31, 2016 · My remaining question is how can I build the tools so that the libs use soft and not hard float support? I guess I misunderstood --disable-float and read it as --disable[-hard]-float! So when I compile now with -msoft-float I get this: riscv64-unknown-elf-gcc: error: unrecognized command line option '-msoft-float'; did you mean '-mno-float'?
