Chad Rosier ef01edf1e9 The Neon VCVT (between floating-point and fixed-point, Advanced SIMD) ... instructions can be used to match combinations of multiply/divide and VCVT (between floating-point and integer, Advanced SIMD). Basically the VCVT immediate operand that specifies the number of fraction bits corresponds to a floating-point multiply or divide by the corresponding power of 2. For example, VCVT (floating-point to fixed-point, Advanced SIMD) can replace a combination of VMUL and VCVT (floating-point to integer) as follows: Example (assume d17 = <float 8.000000e+00, float 8.000000e+00>): vmul.f32 d16, d17, d16 vcvt.s32.f32 d16, d16 becomes: vcvt.s32.f32 d16, d16, #3 Similarly, VCVT (fixed-point to floating-point, Advanced SIMD) can replace a combinations of VCVT (integer to floating-point) and VDIV as follows: Example (assume d17 = <float 8.000000e+00, float 8.000000e+00>): vcvt.f32.s32 d16, d16 vdiv.f32 d16, d17, d16 becomes: vcvt.f32.s32 d16, d16, #3 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133813 91177308-0d34-0410-b5e6-96231b3b80d8		2011-06-24 19:23:04 +00:00
