We have a patch for the new jit3 system in Kaffe 1.0.5 to generate profiling information for the x86 processors. The code has been tested on Pentium II and Pentium III processors. The code has the same limitation with multithreaded code and exceptions as earlier versions of the instrumentation. The patch can be obtained from: http://www.eb.uah.edu/~crash/javanauts/tools/prof.1.0.5.patch Because we are looking at the code generated, the debugging statements in the jit3-i386.def have been reordered to provide a better idea of instruction locations in the generated code. Output has also been added so it is easier to find where the code for a specific method starts. -Will Cohen
