GCJ / libjava 'debug' build -O0

[Peter Blemel]

Hello World,

I'm just now getting back to working on my GCJ cross compiler for a powerpc 
embedded system.   I have everything compiling, linking, loading, and even 
starting on my embedded system(!) but I'm chasing down a class loading 
problem.

My question involves making gdb/insight stick to the right lines.   The 
compiler collection was built with the default -g -O2, but the -O2 is making 
stepping through the 'standard' java program startup where class loading is 
performed a bit troublesome because the optimization makes the code jump 
around a bit in the debugger.   I don't want to change the defaults for the 
rest of the compiler suite, I just want to have libjava build -g -O0.  What 
is the best way to do this?

Thanks,
Peter Blemel
