2025-01-27Add a one-pass baseline compiler for arm64. Nicolas Geoffray
Currently handles 50% of methods by supporting methods that: - don't branch - don't have try/catch - don't have float/double - <= 8 registers - opcodes are const/invokes/iget/iput/const-string/new-instance/checkcast. Cost of compilation is 10 times less than current baseline compiler.

2024-11-06Support all conditions in predicated vectorization Chris Jones
Support all condition types inside the condition when performing diamond loop auto-vectorization. This allows diamond loop auto-vectorization to be performed on a greater variety of loops. To support this change, new vector condition nodes are added to mirror the scalar condition nodes. Also add a new gtest class to test whether predicated vectorization can be performed on different combinations of condition types and data types.

2024-11-05Use .data.img.rel.ro for app image methods. Vladimir Marko
This should improve app startup as we can skip the target method resolution on the first call. For `invoke-direct` we should never go to the resolution trampoline for app image methods and for `invoke-static` we go to the trampoline only if the class is not yet visibly initialized and in that case we still save time as the target method is already known.

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.

2024-09-10riscv64: Add node Rol, fix InstructionBuilder Anton Romanov
Add new IR node Rol (rotate left). This allows to generate 1 (one) risc-v instruction from Integer(Long).rotateLeft intrinsic instead of 2 instructions (Ror+Neg). Fix InstructionBuilder: build Rol from rotateLeft instead of Ror+Neg. Add unfolding of Rol node in InstructionSimplifier(Arm, Arm64 and X86 Int64 type) to Neg+Ror. By compiling with dex2oat all the methods of applications below I got: in Facebook 1 Ror+Neg pattern, in Minecraft 5 Ror+Neg patterns.
