[PATCH 1/7] vm: move code creating exceptions out of signal handlers

It is not safe to execute jit code in signal handler context. One of the reasons is that throwing-by-signal mechanisms don't work in code executed from signal handler. That's becasue kernel will not execute user defined signal handler for SIGSEGV when second signal occures while executing the

[PATCH 6/7] vm: support for stack trace printing

The natives VMThrowable.fillInStackTrace and VMThrowable.getStackTrace are implemented. The stack trace can not be printed yet by invoking printStackTrace() on java.lang.Throwable instance because jato cannot execute PrintStream.print() yet. The stack trace can be however printed when

[PATCH 4/7] vm: put all functions implementing virtual machine native methods in a separate section

All VM natives should be placed in a .vm_native section to allow stack traversal functions to distinguish between regular native functions and native functions which implement native java methods. The former ones do not appear in stack trace but the latter do. Signed-off-by: Tomek Grabiec

[PATCH 5/7] vm: the foundation for java stack trace collecting

A number of utility functions are introduced for backtrace traversal to assist java stack trace collecting. Only JIT methods and VM natives should appear in stack trace so all native functions and trampolines must be filtered out. A new per-thread variable bottom_stack_frame is introduced to

[PATCH 2/7] vm: replace signal_from_jit_method() with signal_from_native()

The rationale for this is the same as for commit 3d406995e21bf1695f6abc743fb37d16cc387f9e (jit: remove is_jit_method() and introduce is_native()) Signed-off-by: Tomek Grabiec tgrab...@gmail.com --- arch/x86/include/arch/signal.h |2 +- arch/x86/signal.c |9 ++---
