This changes the native emitter to access qstr values using the qstr indirection table qstr_table, but only when generating native code that will be saved to a .mpy file. This makes the resulting native code fully static, ie it does not require any fix-ups or rewriting when it is imported. The performance of native code is more or less unchanged. Benchmark results on PYBv1.0 (using --via-mpy and --emit native) are: N=100 M=100 baseline -> this-commit diff diff% (error%) bm_chaos.py 407.16 -> 411.85 : +4.69 = +1.152% (+/-0.01%) bm_fannkuch.py 100.89 -> 101.20 : +0.31 = +0.307% (+/-0.01%) bm_fft.py 3521.17 -> 3441.72 : -79.45 = -2.256% (+/-0.00%) bm_float.py 6707.29 -> 6644.83 : -62.46 = -0.931% (+/-0.00%) bm_hexiom.py 55.91 -> 55.41 : -0.50 = -0.894% (+/-0.00%) bm_nqueens.py 5343.54 -> 5326.17 : -17.37 = -0.325% (+/-0.00%) bm_pidigits.py 603.89 -> 632.79 : +28.90 = +4.786% (+/-0.33%) core_qstr.py 64.18 -> 64.09 : -0.09 = -0.140% (+/-0.01%) core_yield_from.py 313.61 -> 311.11 : -2.50 = -0.797% (+/-0.03%) misc_aes.py 654.29 -> 659.75 : +5.46 = +0.834% (+/-0.02%) misc_mandel.py 4205.10 -> 4272.08 : +66.98 = +1.593% (+/-0.01%) misc_pystone.py 3077.79 -> 3128.39 : +50.60 = +1.644% (+/-0.01%) misc_raytrace.py 388.45 -> 393.71 : +5.26 = +1.354% (+/-0.01%) viper_call0.py 576.83 -> 566.76 : -10.07 = -1.746% (+/-0.05%) viper_call1a.py 550.39 -> 540.12 : -10.27 = -1.866% (+/-0.11%) viper_call1b.py 438.32 -> 432.09 : -6.23 = -1.421% (+/-0.11%) viper_call1c.py 442.96 -> 436.11 : -6.85 = -1.546% (+/-0.08%) viper_call2a.py 536.31 -> 527.37 : -8.94 = -1.667% (+/-0.04%) viper_call2b.py 378.99 -> 377.50 : -1.49 = -0.393% (+/-0.08%) Signed-off-by: Damien George <damien@micropython.org>
