[RFA] _Jv_CompileMethod

[Bryce McKinlay]

Hi Keith,

Why call _Jv_InterpMethod::run() instead of _Jv_InterpMethod::compile() 
directly? That would make more logical sense I think, and the 
compile_mutex locking could be moved into compile() in order to handle 
the case where a request to compile were made simultaneously by both the 
interpreter and the JDWP.

Also, for the current patch, it looks like the "When args is NULL, don't 
run anything -- just compile it." comment is on the wrong method.

Do you have commit access for gcc/libgcj?
