[Sablevm-user] SableVM question

[Marcel A. <ma...@ca...>]

Hello,

I've been researching some clean-room
JVM implementations (Kaffe, Japhar, SableVM)
and have a question regarding the interpreter
loop in SableVM. You use the GCC-extended goto
mechanism to jump to the instruction implementations
while the other two use a switch() statement.
I did a very quick benchmark between these two
methods and it seems the switch() based approach
is much quicker than using goto with a lookup table.

My question is: why use goto instead of switch()?

Thanks in advance,

Marcel Ammerlaan
