2022-11-07Reland "Make compiler/optimizing/ symbols hidden." VladimĂ­r Marko
This reverts commit 0a51605ddd81635135463dab08b6f7c21b58ffb0. Reason for revert: Reland after some of the required work was merged in other CLs. Also address a TODO from the original CL to mark required symbols with EXPORT in `intrinsic_objects.h`. Also mark symbols in new files as HIDDEN. Bug: 186902856 Test: m test-art-host-gtest Test: testrunner.py --host --optimizing Change-Id: I936d448983928af23614ca82c2d0bf9a645e2c52
2019-10-14Revert "Make compiler/optimizing/ symbols hidden." Vladimir Marko
This reverts commit e2727154f25e0db9a5bb92af494d8e47b181dfcf. Reason for revert: Breaks ASAN tests (ODR violation). Bug: 142365358 Change-Id: I38103d74a1297256c81d90872b6902ff1e9ef7a4
2019-10-14Make compiler/optimizing/ symbols hidden. Vladimir Marko
Make symbols in compiler/optimizing hidden by a namespace attribute. The unit intrinsic_objects.{h,cc} is excluded as it is needed by dex2oat. As the symbols are no longer exported, gtests are now linked with the static version of the libartd-compiler library. libart-compiler.so size: - before: arm: 2396152 arm64: 3345280 - after: arm: 2016176 (-371KiB, -15.9%) arm64: 2874480 (-460KiB, -14.1%) Test: m test-art-host-gtest Test: testrunner.py --host --optimizing --jit Bug: 142365358 Change-Id: I1fb04a33351f53f00b389a1642e81a68e40912a8
2017-10-09Use ScopedArenaAllocator for register allocation. Vladimir Marko
Memory needed to compile the two most expensive methods for aosp_angler-userdebug boot image: BatteryStats.dumpCheckinLocked() : 25.1MiB -> 21.1MiB BatteryStats.dumpLocked(): 49.6MiB -> 42.0MiB This is because all the memory previously used by Scheduler is reused by the register allocator; the register allocator has a higher peak usage of the ArenaStack. And continue the "arena"->"allocator" renaming. Test: m test-art-host-gtest Test: testrunner.py --host Bug: 64312607 Change-Id: Idfd79a9901552b5147ec0bf591cb38120de86b01
2017-09-25ART: Introduce compiler data type. Vladimir Marko
Replace most uses of the runtime's Primitive in compiler with a new class DataType. This prepares for introducing new types, such as Uint8, that the runtime does not need to know about.

2016-09-05Avoid excessive spill slots for slow paths. Vladimir Marko
Reducing the frame size makes stack maps smaller as we need fewer bits for stack masks and some dex register locations may use short location kind rather than long. On Nexus 9, AOSP ToT, the boot.oat size reduction is prebuilt multi-part boot image: - 32-bit boot.oat: -416KiB (-0.6%) - 64-bit boot.oat: -635KiB (-0.9%) prebuilt multi-part boot image with read barrier: - 32-bit boot.oat: -483KiB (-0.7%) - 64-bit boot.oat: -703KiB (-0.9%) on-device built single boot image: - 32-bit boot.oat: -380KiB (-0.6%) - 64-bit boot.oat: -632KiB (-0.9%) on-device built single boot image with read barrier: - 32-bit boot.oat: -448KiB (-0.6%) - 64-bit boot.oat: -692KiB (-0.9%) The other benefit is that at runtime, threads may need fewer pages for their stacks, reducing overall memory usage. We defer the calculation of the maximum spill size from the main register allocator (linear scan or graph coloring) to the RegisterAllocationResolver and do it based on the live registers at slow path safepoints. The old notion of an artificial slow path safepoint interval is removed as it is no longer needed. Test: Run ART test suite on host and Nexus 9.
