This patch ties in the array split, merge, and interleave code.
shader-db changes in the TGSI code are:
original code | array-merge | change
mean max | mean max | best mean % worst
-----------------------------------------------------------
arrays 0.05 2 | 0.00 0 | -2 -100 0
total temps 5.05 21 | 4.92 20 | -15 -2.59 1
instr 55.33 988 | 55.20 988 | -15 -0.24 0
Evaluation:
Run shader-db in single thread mode (otherwise the output is
not ordered and the best and worst column don't make sense) to
get results pre-stats.txt and post-stats.txt. Then using
python pandas:
import pandas as pd
old_stats = pd.read_csv('pre-stats.txt')
new_stats = pd.read_csv('post-stats.txt')
omean = old_stats.mean()
omax = old_stats.max()
nmean = new_stats.mean()
nmax = new_stats.max()
delta = new_stats - old_stats
pd.concat([omean, omax, nmean, nmax, delta.min(),
delta.mean()/old_stats.mean()*100, delta.max()],
axis=1, keys=['mean', 'max', 'mean', 'max', 'best',
'avg change %', 'worst'])
v4: - Correct typo and add bugs that are fixed by this series.
- Update stats and describe stats evaluation
