Re: [Sablevm-developer] Porting SableVM to ARM: Questions

[Gunda D. <sab...@ho...>]

Hi Etienne,

Now I am back after the holidays to look at the problem of making the 
inlined version working on ARM.

As per your previous suggestion (in a different discussion thread) I used 
the invocation

sablevm-inlined -v -p sablevm.verbose.methods=true -p 
sablevm.verbose.instructions=true HelloWorldApp

The program fails at different points in different runs. More than half the 
time GOTO is the last instruction executed. But the funny thing is that 
several GOTO's were executed before. Sometimes is fails on IFGT.

Any suggestions ?

Has anybody got sablevm-inlined working on other architectures (other than 
x86) ? I would love to hear their experiences.

Thanks.
-Gunda
