2025-02-19[Sim] Add a restricted mode setup Chris Jones
This CL introduces a special ART setup for all modes (host, target), which is going to be a base for VIXL Simulator Stage 1 setup. This setup can be enabled by exporting ART_USE_RESTRICTED_MODE=true to the environment before building ART. The setup limits ART by doing the following: - Limits the GC to only non-concurent Mark&Sweep. - Turns off the Nterp (so only switch C++ intepreter to be used). - Turns off the JNI compiler (GenericJNITrampoline to be used). - Rejects the compilation of all method (except for the allow list). - Turns off compilation and support of intrinsics. - Turns off implicit null checks. - Turns off implicit suspend checks. - Turns off introspection entrypoints. - Turns off special behavior for critical native methods. - Turns off compiler CHECKER tool. With these limitations it will be easier to start off an initial Simulator Stage 1 setup. As the limitations are set for all the modes, it will be easy to compare/debug the workflow for the simulator mode and to compare it to host and target runs. The CL also adds sections in knownfailures.json for tests that fail in this special setup. Also cleanup some read barrier entrypoint declarations in entrypoints_init_arm64.cc to match the definitions in quick_entrypoints_arm64.S and slightly refactor Runtime::Init to stay below the 500 line limit.

2024-10-07Reland "Calculate the number of out vregs." Vladimír Marko
This reverts commit 434a327234f74eed3ef4072314d2e2bdb73e4dda. Reason for revert: Relanding with no change. The regressions that were the reason for the revert may reappear. However, these regressions are probably caused by subtle effects that are not directly related to this change. For example, a code size improvement can regress performance simply by moving the start of a loop from an aligned address to an unaligned address, or by splitting a loop across two cache lines.

This is done like this due to GenerateVarHandleSet also calling HandleFieldSet.

2024-01-19Revert "Disable write-barrier elimination pass" Santiago Aboy Solanes
This reverts commit 5a3271d7caafefd10a20f5a5db09d2c178838b76. Reason for revert: This CL has two fixes (codegen not doing a null check if a write barrier is being relied on, and codegen not recomputing skipping write barriers), regression tests, a new runtime check which runs in debug mode for the CC GC to ensure that the card table is set correctly for skipped write barriers, and new compile time (graph checker) tests to ensure graph consistency. This patchset updates the WriteBarrierKind to be {emit being relied on, emit not being relied on, dont emit}, which leaves the null check skip implementation to codegen. Test 2247- is removed from knownfailures.json but still skipped in MTS due to SLO requirements.

2023-12-13riscv64: Clean up the `SystemArrayCopy` intrinsic. Vladimir Marko
Define a new optimization flag for source and destination position match. Use it to avoid the forward-copy check (where the assembler optimized away a BLT instruction, so we had just a useless BNE to the next instruction) and one position sign check. Avoid checking that the position is inside the array. The subsequent subtraction cannot underflow an `int32_t` and the following BLT shall go to the slow path for negative values anyway. Rewrite the array type check to avoid unnecessary checks and read barriers. Use an allocated temporary instead of scratch register for the marking in the read barrier slow path. Simplify the gray bit check and the fake dependency. Use constant position and length locations for small constant values. (It was probably an oversight that we used it only for large constant values.) Emit threshold check when the length equals source or destination length. The old code allowed the intrinsic to process array copy of an arbirary length. Use `ShNAdd()` for faster array address calculations. Use helper functions and lambdas to simplify the code. Pass registers and locations by value. Prefer load/store macro instructions over raw load/store instructions. Use a bare conditional branch to assert the `TMP` shall not be clobbered.

2023-04-27Optimizing: Add `HInstruction::As##type()`. Vladimir Marko
After the old implementation was renamed in https://android-review.googlesource.com/2526708 , we introduce a new function with the old name but new behavior, just `DCHECK()`-ing the instruction kind before casting down the pointer. We change appropriate calls from `As##type##OrNull()` to `As##type()` to avoid unncessary run-time checks and reduce the size of libart-compiler.so.

2023-04-27Optimizing: Rename `As##type` to `As##type##OrNull`. Vladimir Marko
The null type check in the current implementation of `HInstruction::As##type()` often cannot be optimized away by clang++. It is therefore beneficial to have two functions HInstruction::As##type() HInstruction::As##type##OrNull() where the first function never returns null but the second one can return null. The additional text "OrNull" shall also flag the possibility of yielding null to the developer which may help avoid bugs similar to what we have seen previously. This requires renaming the existing function that can return null and introducing new function that cannot. However, defining the new function `HInstruction::As##type()` in the same change as renaming the old one would risk introducing bugs by missing a rename. Therefore we simply rename the old function here and the new function shall be introduced in a separate change with all behavioral changes being explicit.

2022-10-07Runtime implementation of try catch inlining Santiago Aboy Solanes
The main differences in the runtime are: 1) We now use a list of dex_pcs to find the correct catch handler instead of a single dex pc 2) We now need to restore vregs of the whole frame, which may be an inline frame.

2022-09-06Add an environment to the beginning of catch blocks Santiago Aboy Solanes
We can use the HNop to generate an environment for us and start using the existing environment infrastructure (e.g. EmitEnvironment) for recording the catch block's environment. This is done to provide support for try catch inlining since it requires several environments rather than just the one. When doing so, we now have a HNop at the beginning of each catch block. We have to modify code sinking to allow it to sink code past this HNop because if we don't we will sink code right before this instruction which will break the invariant of that HNop being the first instruction of a catch block.
