[Mono-devel-list] [PATCH] Use smallest encoding for <alu> eax, imm

[Ben Maurer]

Hello,

The attached patch uses the smallest possible encoding for operations
such as

add eax, 5

Before we emitted 5 as a 32 bit value in order to save one bit by using
the eax trick -- a foolish trade.

Results:

# Before
[benm at Ben mono]$ mono --stats --compile-all /devel/mcs/class/lib/default/mscorlib.dll | grep Native
Native code size:       1429905
# After
[benm at Ben mono]$ mini/mono --stats --compile-all /devel/mcs/class/lib/default/mscorlib.dll | grep Native
Native code size:       1424838
