* Move image intern table into imageMathieu Chartier2015-06-112-7/+42
| | | | | | | | | | | | | Previously we recreated this intern table during runtime startup. This added 50-100ms of boot time. Fixed bug where we didn't copy over hashcodes into the image. Deleted some stale code. Bug: 20727525 Bug: 19569780 Change-Id: I08959e9aa2a73cedb52f393033e2ffea3a26e76b
* Move mirror::ArtMethod to nativeMathieu Chartier2015-06-022-64/+130

TODO: Test and fix bugs in mips64. Saves 16 bytes per most ArtMethod, 7.5MB reduction in system PSS. Some of the savings are from removal of virtual methods and direct methods object arrays. Bug: 19264997 (cherry picked from commit e401d146407d61eeb99f8d6176b2ac13c4df1e33) Change-Id: I622469a0cfa0e7082a2119f3d6a9491eb61e3f3d Fix some ArtMethod related bugs Added root visiting for runtime methods, not currently required since the GcRoots in these methods are null. Added missing GetInterfaceMethodIfProxy in GetMethodLine, fixes --trace run-tests 005, 044. Fixed optimizing compiler bug where we used a normal stack location instead of double on ARM64, this fixes the debuggable tests. TODO: Fix JDWP tests.

Now we properly compare the size of the image space against the size of the image file.

* ART: Clean up arm64 kNumberOfXRegisters usage.Vladimir Marko2015-05-261-1/+0
| | | | | | | | | | | | | | | | | | | | | Avoid undefined behavior for arm64 stemming from 1u << 32 in loops with upper bound kNumberOfXRegisters. Create iterators for enumerating bits in an integer either from high to low or from low to high and use them for <arch>Context::FillCalleeSaves() on all architectures. Refactor runtime/utils.{h,cc} by moving all bit-fiddling functions to runtime/base/bit_utils.{h,cc} (together with the new bit iterators) and all time-related functions to runtime/base/time_utils.{h,cc}. Improve test coverage and fix some corner cases for the bit-fiddling functions.

* ART: Do not relocate app program headers in patchoat.Vladimir Marko2015-05-141-7/+12
| | | | | | | | | | | | | | | | Change the check whether to relocate program headers in patchoat to simply look whether there is a PT_LOAD section with p_vaddr == 0. If there is, don't relocate the headers, it should be an app. Otherwise, it's a boot image and needs to be relocated. Add overflow checking to ElfFileImpl<>::GetLoadedSize().

* Relocate DWARF using .oat_patches.David Srbecky2015-04-112-80/+1
| | | | | | | | | | | | | | | | | | | | | | 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.

* ART: Allow to compile interpret-only mips64 filesAndreas Gampe2015-01-151-0/+2
| | | | | | | | | | | | Include enough infrastructure to allow cross-compiling for mips64, interpret-only. This includes the instruction-set-features, frame size info and utils assembler. Also add a disassembler for oatdump, and support in patchoat. Note: the runtime cannot run mips64, yet. Change-Id: Id106581fa76b478984741c62a8a03be0f370d992

* Change 64 bit ArtMethod fields to be pointer sizedMathieu Chartier2014-11-182-23/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | Changed the 64 bit entrypoint and gc map fields in ArtMethod to be pointer sized. This saves a large amount of memory on 32 bit systems. Reduces ArtMethod size by 16 bytes on 32 bit. Total number of ArtMethod on low memory mako: 169957 Image size: 49203 methods -> 787248 image size reduction. Zygote space size: 1070 methods -> 17120 size reduction. App methods: ~120k -> 2 MB savings. Savings per app on low memory mako: 125K+ per app (less active apps -> more image methods per app). Savings depend on how often the shared methods are on dirty pages vs shared. TODO in another CL, delete gc map field from ArtMethod since we should be able to get it from the Oat method header.

* Fix 2 new sets of clang compiler warnings.Ian Rogers2014-10-101-0/+1
| | | | | | | | | | | Fix issues that are flagged by -Wfloat-equal and -Wmissing-noreturn. In the case of -Wfloat-equal the current cases in regular code are deliberate, so the change is to silence the warning. For gtest code the appropriate fix is to switch from EXPECT_EQ to EXPECT_(FLOAT|DOUBLE)_EQ. The -Wmissing-noreturn warning isn't enabled due to a missing noreturn in gtest. This issue has been reported to gtest. Change-Id: Id84c70c21c542716c9ee0c41492e8ff8788c4ef8

* ART source line debug info in OAT filesYevgeny Rouban2014-08-151-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).
