Comment(by ezyang):
This patch, plus the SpLim checks:
{{{
Min +6.1% -0.1% -8.6% -8.0% -50.0%
Max +6.8% +5.8% +4.8% +5.5% +1.3%
Geometric Mean +6.7% +0.1% +0.0% +0.0% -0.7%
}}}
Good things for runtime, but not all that much difference for code size.
This patch only (without SpLim checks)
{{{
Min +5.7% -0.0% -6.5% -6.4% -50.0%
Max +6.3% +5.8% +5.0% +5.5% +0.8%
Geometric Mean +6.2% +0.1% +0.5% +0.5% -0.8%
}}}
