The current VFP code has two different idioms for loading and storing from the VFP register file: 1 using the gen_mov_F0_vreg() and similar functions, which load and store to a fixed set of TCG globals cpu_F0s, CPU_F0d, etc 2 by direct calls to tcg_gen_ld_f64() and friends We want to phase out idiom 1 (because the use of the fixed globals is a relic of a much older version of TCG), but idiom 2 is quite longwinded: tcg_gen_ld_f64(tmp, cpu_env, vfp_reg_offset(true, reg)) requires us to specify the 64-bitness twice, once in the function name and once by passing 'true' to vfp_reg_offset(). There's no guard against accidentally passing the wrong flag. Instead, let's move to a convention of accessing 64-bit registers via the existing neon_load_reg64() and neon_store_reg64(), and provide new neon_load_reg32() and neon_store_reg32() for the 32-bit equivalents. Implement the new functions and use them in the code in translate-vfp.inc.c. We will convert the rest of the VFP code as we do the decodetree conversion in subsequent commits.
