Hi, The current blocker bug for a simple "hello, world" application is in the way Jato handles mimic stack on basic block boundaries. The problem is that a mimic stack can be non-empty at the end of a basic block because of, for example, the ternary operator. You can find a full explanation of the problem in the following paper:
http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.47.6374 [ Just search for "mimic stack" for the relevant section. ] To fix the bug, I had to change the bytecode parsing code to work on basic blocks so that we can actually do the mimic stack spilling and reloading. The infrastructure changes are done now but the actual spilling/reloading logic is still missing. You can find the failing regression test case here: http://git.kernel.org/?p=java/jato/jato.git;a=commitdiff;h=a75b9eafb156bd9065a6d3f48bc4047d800e79f2 and the per basic block parsing code here: http://git.kernel.org/?p=java/jato/jato.git;a=commitdiff;h=39012fdc943f747dd740369d69140bdfa5658e85 Unfortunately I cannot commit the latter to mainline as the change exposes a latent bug in the current regression tests.
