It depends on the -ffast-math option. When we would like to call ceil/ceilf like v2 = ceil (v1), we will convert it into below insn (reference the implementation of llvm). * vfcvt.x.f v3, v1, RUP * vfcvt.f.x v2, v3 However, the floating point value may not need the cvt as above if its mantissa is zero. For example single precision floating point below. +-----------+---------------+ | float | binary layout | +-----------+---------------+ | 8388607.5 | 0x4affffff | | 8388608.0 | 0x4b000000 | | 8388609.0 | 0x4b000001 | +-----------+---------------+ All single floating point great than 8388608.0 will have all zero mantisaa. We leverage vmflt and mask to filter them out in vector and only do the cvt on mask.
