MIPS32: Improve stack alignment, use sdc1/ldc1, where possible. - Ensure that SP is a multiple of 16 at all times, and - Use ldc1/sdc1 to load/store FPU registers from/to 8-byte-aligned locations wherever possible. Use `export ART_MIPS32_CHECK_ALIGNMENT=true` when building Android to enable the new runtime alignment checks. Test: Boot & run tests on 32-bit version of QEMU, and CI-20. Test: test/testrunner/testrunner.py --target --optimizing --32 Test: test-art-host-gtest Test: test-art-target-gtest Change-Id: Ia667004573f419fd006098fcfadf5834239cb485

Change remaining slow path throw entrypoints to save everything. Change DivZeroCheck, BoundsCheck and explicit NullCheck slow path entrypoints to conform to kSaveEverything. On Nexus 9, AOSP ToT, the boot.oat size reduction is prebuilt multi-part boot image: - 32-bit boot.oat: -12KiB (-0.04%) - 64-bit boot.oat: -24KiB (-0.06%) on-device built single boot image: - 32-bit boot.oat: -8KiB (-0.03%) - 64-bit boot.oat: -16KiB (-0.04%) Test: Run ART test suite including gcstress on host and Nexus 9.

Revert "Revert "Use implicit null checks inside try blocks."" Fix implicit checks in try blocks to emit stack maps. Fix arm64 null expection from signal entrypoint to call the runtime handler instead or simply jumping there. On Nexus 9, AOSP ToT, the boot.oat size reduction is prebuilt multi-part boot image: - 32-bit boot.oat: -448KiB (-1.3%) - 64-bit boot.oat: -528KiB (-1.2%) on-device built single boot image: - 32-bit boot.oat: -448KiB (-1.4%) - 64-bit boot.oat: -528KiB (-1.3%) Note that the oat files no longer contain dex files which have been moved to vdex, so the percentages are not directly comparable with the those reported in the original commit. Test: Run ART test suite including gc-stress on host and Nexus 9. Bug: 30212852 Bug: 31468464 This reverts commit 0719b5b9b458cb3eb9f0823f0dacdfe1a71214dd.

Use implicit null checks inside try blocks. Make implicit null check entrypoint save all registers, use platform-specific approach to still pass the fault address. Allow implicit null checks in try blocks. On Nexus 9, AOSP ToT, the boot.oat size reduction is prebuilt multi-part boot image: - 32-bit boot.oat: -452KiB (-0.7%) - 64-bit boot.oat: -482KiB (-0.7%) on-device built single boot image: - 32-bit boot.oat: -444KiB (-0.7%) - 64-bit boot.oat: -488KiB (-0.7%) Test: Run ART test suite on host and Nexus 9.

Refactor quick entrypoints Remove FinishCalleeSaveFrameSetup. Assembly routines write down anchor into TLS as well as placing runtime method in callee save frame. Simplify artSet64InstanceFromCode by not computing the referrer from the stack in the C++ code. Move assembly offset tests next to constant declaration and tidy arch_test.

Add "arch_test" gtest for assembly stub constants, add some ARM64 assembly code Add a test that (1) checks all callee-save method frame sizes for all architectures, (2) checks thread offsets for the runtime architecture and (3) checks callee-save method offsets for the runtime architecture. The "asm_support_XXX.h" files now only contain definitions that are common between all architectures. Architecture-specific definitions (i.e., special registers names) have been pushed into the corresponding .S file. This change was required to be able to undefine definitions in the test, so that multiple tests can be written in one file. Test (1) above is in a sense two-stage. The arch_test gtest compares constants (if it finds them) against the frame size as reported by the ArtMethods created by the Runtime. This works for all architectures as we can provide the instruction-set to CreateCalleeSaveMethod. The second stage of the "test" are preprocessor tests with "#error" in the case that the constants are not the expected value. Optimally I'd like to change that to an actual runtime test exercising the assembly code, which would also allow to check whether the right registers are stored. Also added missing assembly code for ARM64 for the callee-save macros. Also fix X86_64 compilation for Clang 3.5. Change-Id: I018e6433dffd3d31ba3bfcd75661653f4c7b6552

Always reset CFI state. .cfi_startproc simple may do even less than .cfi_startproc, so don't rely on it. Instead, use regular .cfi_startporc and always set up the expected entry state. Change-Id: I6d3e8b8e4a07621bc99c062359a109eb76f85184

Ensure functions start with clean CFA state. .cfi_startproc doesn't reset CFA state and so delivering exceptions and the like can leave the CFA with an incorrect offset. Reset the state in the DEFINE_FUNCTION macro. Also fix using test/run-test with --gdb for the target. Change-Id: I4c03768e118ef1e06d34fedce856919e6ecba0c4

Entry point clean up. Create set of entry points needed for image methods to avoid fix-up at load time: - interpreter - bridge to interpreter, bridge to compiled code - jni - dlsym lookup - quick - resolution and bridge to interpreter - portable - resolution and bridge to interpreter Fix JNI work around to use JNI work around argument rewriting code that'd been accidentally disabled. Remove abstact method error stub, use interpreter bridge instead. Consolidate trampoline (previously stub) generation in generic helper. Simplify trampolines to jump directly into assembly code, keeps stack crawlable. Dex: replace use of int with ThreadOffset for values that are thread offsets. Tidy entry point routines between interpreter, jni, quick and portable. Change-Id: I52a7c2bbb1b7e0ff8a3c3100b774212309d0828e (cherry picked from commit 848871b4d8481229c32e0d048a9856e5a9a17ef9)
