* ART: Make elf loading not abortAndreas Gampe2014-09-151-114/+351
| | | | | | | | | | | | | | Changes elf_file code to use less CHECKs and instead return error values (usually nullptr). This avoids aborts. In oat_file, when loading an oat file fails, try to unlink at. If this succeeds, on the next run we may compile again. Bug: 17491333 (cherry picked from commit afa6b8e93a0dc0de33c9d404945c7c5621e20b1a) Change-Id: I50fdd2edacd86f25d4dacf2180ce2a6105eaf4af
* ART: Better error reporting on broken oat fileAndreas Gampe2014-09-091-0/+4
| | | | | | | | | | | | Do not blow up when in GetHashBucket if GetHashBucketNum is zero. Instead back-step to ElfFileOpen, which prints which symbol was missing from which file.

* ART source line debug info in OAT filesYevgeny Rouban2014-08-151-42/+226
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* ART: Fix memory unmapped twice issue in ElfFile::Load(bool)Jim_Guo2014-08-041-9/+15
| | | | | | | | | | | | | | | | | Root Cause: The overlapped memory region will be unmapped by (1) ~MemMap() of reservation MemMap (reserve) and (2) ~MemMap() of "reuse" MemMap (segment). Someone takes the memory region after (1) and it will be unmapped in (2). So, SIGSEGV occurs when using the unmapped memory region. Solution: Fixes this issue by skip unmap "reuse" MemMap in destructor. And always create reservation MemMap before "reuse" MemMap. (It also solved the fixupELF case which does not reserve the whole needed memory region). Bug: 16486685 Change-Id: I8f2538861d5c3fa7b9a04d2c3f516319cc060291
* 1. Fix CFI for quick compiled code in x86 & x86_64;Tong Shen2014-07-301-19/+9
| | | | | | | | | | | | | | | | 2. Emit CFI in .eh_frame instead of .debug_frame. With CFI, we can correctly unwind past quick generated code. Now gdb should unwind to main() for both x86 & x86_64 host-side ART. Note that it does not work with relocation yet. Testing: 1. art/test/run-test --host --gdb [--64] --no-relocate 005 2. In gdb, run 'b art_quick_invoke_stub', then 'r', then 'c' a few times 3. In gdb, run 'bt'. You should see stack frames down to main() Change-Id: I5350d4097dc3d360a60cb17c94f1d02b99bc58bb
* Add patchoat tool to Art.Alex Light2014-07-071-5/+14
| | | | | | | | | | | | | Add a new executable called patchoat to art. This tool takes already compiled images and oat files and changes their base address, acting as a cheap form of relocation. Add a --include-patch-information flag to dex2oat and code to add required patch information to oat files created with the quick compiler.

* Fixed gdb support and added some ElfFile functionsAlex Light2014-06-271-295/+417
| | | | | | | | | | | | | | | | | | Fixed gdb support so that it would continue working even when debug symbols or other sections are included in the elf file. Also made it actually read parts of the DWARF information so it should work even if there are minor changes to how and where DWARF information is written out. Added a dwarf.h file with the dwarf constants. Added a FindSectionByName function, a FindDynamicSymbol function, and the ability to specify the mmap protection and flags directly if we are mapping in the whole file. Modified elf_writer_quick.cc to use the dwarf constants from dwarf.h. Change-Id: I09e15c425fab252b331a2e4719863552e8b6b137

* Make MemMap::MapAnonymous() fail if the requested address is not available.Hiroshi Yamauchi2014-03-141-2/+2
| | | | | | | | | | | | | | | | | | Change MapAnonymous() so that a requested address vs. actual map address mismatch will cause a failure. The existing MapAnonymous() call sites do not check this. This should prevent potential rare case bugs where mmap does not happen to map a region at an specified address. There's a potential bug that if MapAnonymous() does not guarantee the requested address (and there's a gap between the image/oat files and the zygote/malloc space), then GC could in theory allocate a large object space in the gap. This would break the GC notion of the immune space. This change will prevent this by causing all non-moving spaces to be (really) adjacent, with no gaps in between, which CL 87711 missed.

| | | | | | | | | If the file is to be purely interpreted, the .text segment will be of zero length and won't get a segment mapped. Currently this will cause a check failure, but we should just exit if the GDB JIT support cannot be enabled. Change-Id: Iea3834ee5c1313837ebcbe3b58ecd2dc924c1b1e

* Tell GDB about Quick ART generated codeMark Mendell2014-03-021-1/+354
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is actually a lot of work. To do this, we need: .debug_info .debug_abbrev .debug_frame .debug_str These are generated into the OAT file by OatWriter and ElfWriterQuick. Since the Quick ART runtime doesn't use dlopen to load the OAT files, GDB can't find this information. Use the alternate GDB JIT interface, which can be invoked at runtime. To use this interface, an ELF image needs to be built in memory. Read the information from the OAT file, fixup the addresses to point to the real locations, add a symbol table to hold the .text symbol, and then let GDB know about the information, which will be read from the runtime address space. This is quite primitive now, and could be cleaned up considerably. It probably needs symbol table entries for the methods, and descriptions of parameters and return types. Currently only supported for X86. This defaults to enabled for debug builds. Added dexoat --gen-gdb-info and --no-gen-gdb-info flags to override.

* Object model changes to support 64bit.Ian Rogers2014-02-061-1/+2
| | | | | | | | | | | | | | | | | | | | | | | Modify mirror objects so that references between them use an ObjectReference value type rather than an Object* so that functionality to compress larger references can be captured in the ObjectRefererence implementation. ObjectReferences are 32bit and all other aspects of object layout remain as they are currently. Expand fields in objects holding pointers so they can hold 64bit pointers. Its expected the size of these will come down by improving where we hold compiler meta-data. Stub out x86_64 architecture specific runtime implementation. Modify OutputStream so that reads and writes are of unsigned quantities. Make the use of portable or quick code more explicit. Templatize AtomicInteger to support more than just int32_t as a type. Add missing, and fix issues relating to, missing annotalysis information on the mutator lock. Refactor and share implementations for array copy between System and uses elsewhere in the runtime.

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.
