* ART stack unwinding fixes for libunwind/gdb/lldb.David Srbecky2015-06-191-65/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dex2oat can already generate unwinding and symbol information which allows tools to create backtrace of mixed native and Java code. This is a cherry pick from aosp/master which fixes several issues. Most notably: * It enables generation of ELF-64 on 64-bit systems (in dex2oat, C compilers already produce ELF-64). Libunwind requires ELF-64 on 64-bit systems for backtraces to work. * It enables loading of ELF files with dlopen. This is required for libunwind to be able to generate backtrace of current process (i.e. the process requesting backtrace of itself). * It adds unit test to test the above (32 vs 64 bit, in-proces vs out-of-process, application code vs framework code). * Some other fixes or clean-ups which should not be of much significance but which are easier to include to make the important CLs cherry-pick cleanly.

* Relocate DWARF using .oat_patches.David Srbecky2015-04-111-0/+72
| | | | | | | | | | | | | | | | | | | | | | The current solution is to hard-code knowledge of DWARF in the linker. This works for simple use of DWARF, but breaks as soon as I try to do anything more complex. Making the linker fully support DWARF would be non-trivial task and would be essentially rewrite. Using .oat_patches is much easier solution. Relocating .debug_* sections required extending .oat_patches to support more sections than just .text. I have encoded each section as null-terminated section name followed by ULEB128 deltas. The ULEB128 encoding shrinks .oat_patches for .text by factor of about 6 with 64-bit compiler, and factor of 3 with 32-bit compiler. On the other hand, it grows by the extra .oat_patches for DWARF which were not present before (if debug symbols are included). Overall, it is still a clear improvement even with the DWARF patches.

* Create separate Android.mk for main build targetsBrian Carlstrom2013-07-121-0/+92
The runtime, compiler, dex2oat, and oatdump now are in seperate trees to prevent dependency creep. They can now be individually built without rebuilding the rest of the art projects. dalvikvm and jdwpspy were already this way. Builds in the art directory should behave as before, building everything including tests. Change-Id: Ic6b1151e5ed0f823c3dd301afd2b13eb2d8feb81
