Hence, the need for NaN boxing is diminished. Sign-extending 32-bit floating-point numbers when held in RV64 `x` -registers matches the existing RV64 calling conventions, which require -all 32-bit types to be sign-extended when passed or returned in `x` -registers. To keep the architecture more regular, we extend this pattern -to 16-bit floating-point numbers in both RV32 and RV64. +registers is compatible with the existing RV64 calling conventions, which leave bits 63-32 undefined when passing a 32-bit floating point value in `x` registers. To keep the architecture more regular, we extend this pattern to 16-bit floating-point numbers in both RV32 and RV64. ==== === Zdinx |
