Fix an Alloc setting to allow running valgrind. Refactor the fault handler to manage (and correctly release) the handlers. Fix minor failure-case leaks exposed by tests. Failing tests: The optimizing compiler is leaking non-arena-ed structures (e.g., assembler buffers), as code generators are not destroyed. The solution has been moved to a follow-up CL. Note: All 64b tests are failing as we cannot allocate a heap. Change-Id: I7f854cfd098d9f68107ce492363e7dba9a82b9fa

* ART source line debug info in OAT filesYevgeny Rouban2014-08-154-29/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OAT files have source line information enough for ART runtime needs like jump to/from interpreter and thread suspension. But this information is not enough for finer grained source level debugging and low-level profiling (VTune or perf). This patch adds to OAT files two additional sections: .debug_line - DWARF formatted Elf32 section with detailed source line information (mapping from native PC to Java source lines). In addition to the debugging symbols added using the dex2oat option --include-debug-symbols, the source line information is added to the section .debug_line. The source line info can be read by many Elf reading tools like objdump, readelf, dwarfdump, gdb, perf, VTune, ... gdb can use this debug line information in x86. In 64-bit mode the information can be used if the oat file is mapped in the lower address space (address has higher 32 bits zeroed). Relocation works. Testing: 1. art/test/run-test --host --gdb [--64] 001-HelloWorld 2. in gdb: break Main.java:19 3. in gdb: break Runtime.java:111 4. in gdb: run - stops at void java.lang.Runtime.<init>() 5. in gdb: backtrace - shows call stack down to main() 6. in gdb: continue - stops at void Main.main() (only in 32-bit mode) 7. in gdb: backtrace - shows call stack down to main() 8. objdump -W <oat-file> - addresses are from VMA range of .text section reported by objdump -h <file> 9. dwarfdump -ka <oat-file> - no errors expected Size of aosp-x86-eng boot.oat increased by 11% from 80.5Mb to 89.2Mb with two sections added .debug_line (7.2Mb) and .rel.debug (1.5Mb).

| * Reduce stack usage for overflow checksDave Allison2014-08-131-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reduces the stack space reserved for overflow checks to 12K, split into an 8K gap and a 4K protected region. GC needs over 8K when running in a stack overflow situation. Also prevents signal runaway by detecting a signal inside code that resulted from a signal handler invokation. And adds a max signal count to the SignalTest to prevent it running forever. Also reduces the number of iterations for the InterfaceTest as this was taking (almost) forever with the --trace option on run-test. Bug: 15435566 Change-Id: Id4fd46f22d52d42a9eb431ca07948673e8fda694

| | | | | | | | | | | Now for host-side x86 & x86_64 ART, we are able to get complete stacktrace with even mixed C/C++ & Java stack frames. Testing: 1. art/test/run-test --host --gdb [--64] --no-relocate 005 2. In gdb, run 'b art::Class_classForName' which is implementation of a Java native method, then 'r' 3. In gdb, run 'bt'.

| | | | | | | | | | | | | | Create ArenaAllocatorAdapter, similar to the existing ScopedArenaAllocatorAdapter, for allocating memory for standard containers via the ArenaAllocator. Add the ability to specify allocation kind rather than just kArenaAllocSTL to both adapters. Move the scoped arena allocator to the scoped_arena_containers.h header file. Define template aliases for containers using the new adapter and change a few MIRGraph and Mir2Lir members to use them. Change-Id: I9bbc50248e0fed81729497b848cb29bf68444268

* AArch64: Clean up CalleeSaveMethod frame and the use of temp registers.Zheng Xu2014-07-292-29/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | CalleeSaveMethod frame size changes : SaveAll : 368 -> 176 RefOnly : 176 -> 96 RefsAndArgs : 304 -> 224 JNI register spill size changes : 160 -> 88 In the transition assembly, use registers following the rules: 1. x0-x7 as temp/argument registers. 2. IP0, IP1 as scratch registers. 3. After correct type of callee-save-frame has been setup, all registers are scratch-able(probably except xSELF and xSUSPEND). 4. When restore callee-save-frame, IP0 and IP1 should be untouched. 5. From C to managed code, we assume all callee save register in AAPCS will be restored by managed code except x19(SUSPEND). In quick compiler: 1. Use IP0, IP1 as scratch register. 2. Use IP1 as hidden argument register(IP0 will be scratched by trampoline.) Change-Id: I05ed9d418b01b9e87218a7608536f57e7a286e4c
