* ART: Swap-space in the compilerAndreas Gampe2014-12-221-42/+100
| | | | | | | | | | | Introduce a swap-space and corresponding allocator to transparently switch native allocations to memory backed by a file. Bug: 18596910 (cherry picked from commit 62746d8d9c4400e4764f162b22bfb1a32be287a9) Change-Id: I131448f3907115054a592af73db86d2b9257ea33

* Remove method verification results right after compiling a methodMathieu Chartier2014-12-031-0/+4
| | | | | | | | | | | | | | This saves memory since it allows the code arrays from methods compiled in future methods to use the ram we just freed from the verification results.

* Instruction set features for ARM64, MIPS and X86.Ian Rogers2014-11-131-1/+2
| | | | | | | | | | | | | Also, refactor how feature strings are handled so they are additive or subtractive. Make MIPS have features for FPU 32-bit and MIPS v2. Use in the quick compiler rather than #ifdefs that wouldn't have worked in cross-compilation. Add SIMD features for x86/x86-64 proposed in: https://android-review.googlesource.com/#/c/112370/ Bug: 18056890 Change-Id: Ic88ff84a714926bd277beb74a430c5c7d5ed7666
* ART: Compiled-classes list for compiler-driverAndreas Gampe2014-11-131-1/+11
| | | | | | | | | | | | Similar to the image-classes list, introduce a list of class names that are to be compiled when creating a boot image. This defaults to all classes. Bug: 18336591 (cherry picked from commit 26318f722958ac1cba6a812026a1377f37c54941) Change-Id: I95f69afdb500a9defb6795803d4040bbe67c5a01
* Remove -Wno-unused-parameter and -Wno-sign-promo from base cflags.Ian Rogers2014-11-031-0/+1
| | | | | | | | | | | Fix associated errors about unused paramenters and implict sign conversions. For sign conversion this was largely in the area of enums, so add ostream operators for the effected enums and fix tools/generate-operator-out.py. Tidy arena allocation code and arena allocated data types, rather than fixing new and delete operators. Remove dead code. Change-Id: I5b433e722d2f75baacfacae4d32aef4a828bfe1b

* C++11 related clean-up of DISALLOW_..Ian Rogers2014-10-221-10/+0
| | | | | | | | | | | | | | | | | | Move DISALLOW_COPY_AND_ASSIGN to delete functions. By no having declarations with no definitions this prompts better warning messages so deal with these by correcting the code. Add a DISALLOW_ALLOCATION and use for ValueObject and mirror::Object. Make X86 assembly operand types ValueObjects to fix compilation errors. Tidy the use of iostream and ostream. Avoid making cutils a dependency via mutex-inl.h for tests that link against libart. Push tracing dependencies into appropriate files and mutex.cc. x86 32-bit host symbols size is increased for libarttest, avoid copying this in run-test 115 by using symlinks and remove this test's higher than normal ulimit. Fix the RunningOnValgrind test in RosAllocSpace to not use GetHeap as it returns NULL when the heap is under construction by Runtime. Change-Id: Ia246f7ac0c11f73072b30d70566a196e9b78472b

Add to instruction_set_test to warn when InstructionSetFeatures don't agree with ones from system properties, AT_HWCAP and /proc/cpuinfo. Clean-up class linker entry point logic to not return entry points but to test whether the passed code is the particular entrypoint. This works around image trampolines that replicate entrypoints.

* Implement method calls using relative BL on ARM.Vladimir Marko2014-09-251-227/+5
| | | | | | | | | | Store the linker patches with each CompiledMethod instead of keeping them in CompilerDriver. Reorganize oat file creation to apply the patches as we're writing the method code.

* ART fix oat debug source map operationsYevgeny Rouban2014-08-251-3/+3
| | | | | | | | | | | | | | | | | | | | | | Several places need to be fixed in OAT debug source map generation (see comments in https://android-review.googlesource.com/#/c/102610/19/compiler/compiled_method.h): 1. Source Maps are deduplicated in Compiler Driver by implicit conversion SrcMapElems to bytes. This implies incorrect operator==. 2. SrcMapElem operator < is peculiar, and cannot be applied to SrcMapElems with negative to_ fields 3. SrcMap.Arrange method is not elegant The fix is to introduce explicit conversion from SrcMapElem to one signed 64-bit value, which is used as a base of two new operators < and ==. They are correct and intuitive. DedupeHashFunc is changed to explicitly convert array elements to byte, so the explicit type conversion from SrcMapElem to byte is used. Minor fix: In Line Table Programs the file index set command is generated only if the index gets new value.

* ART source line debug info in OAT filesYevgeny Rouban2014-08-151-7/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* Avoid use of std::string where we have const char*.Ian Rogers2014-08-121-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Removing the ClassHelper caused std::string creation for all calls to Class::GetDescriptor and a significant performance regression. Make the std::string an out argument so the caller can maintain it and its life time while allowing GetDescriptor to return the common const char* case. Don't generate GC maps when compilation is disabled. Remove other uses of std::string that are occuring on critical paths. Use the cheaper SkipClass in CompileMethod in CompilerDriver. Specialize the utf8 as utf16 comparison code for the common shorter byte encoding. Force a bit of inlining, remove some UNLIKELYs (they are prone to pessimizing code), add some LIKELYs. x86-64 host 1-thread interpret-only of 57 apks: Before: 29.539s After: 23.467s Regular compile: Before: 1m35.347s After: 1m20.056s Bug: 16853450 Change-Id: Ic705ea24784bee24ab80084d06174cbf87d557ad

Fixed bug where Intel DWARF information would not correctly deal with deduplicated code the binary. Changed the portable compiler code path in dex2oat.cc so that symbols will not be stripped when run with --include-debug-symbols. Change-Id: Ia2eb2f654dedf0e5e8606f7744e05b8d14155fb1
