annotate make/linux/makefiles/gcc.make @ 1410:b30a2cd5e3a2
Added methods to c1x_VMExits.cpp
Some memos:
- the result is not stored in a jobject, but in an oop! => (oop)get_as_jobject()
- we get problems with locks hold by the user program when disabling background compilation => currently this makes an assert, we need a better solution
