2022-11-07Reland "Make compiler/optimizing/ symbols hidden." Vladimír 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
2018-08-28Use 'final' and 'override' specifiers directly in ART. Roland Levillain
Remove all uses of macros 'FINAL' and 'OVERRIDE' and replace them with 'final' and 'override' specifiers. Remove all definitions of these macros as well, which were located in these files: - libartbase/base/macros.h - test/913-heaps/heaps.cc - test/ti-agent/ti_macros.h ART is now using C++14; the 'final' and 'override' specifiers have been introduced in C++11.

2016-12-15ART: Move to libbase StringPrintf Andreas Gampe
Remove ART's StringPrintf implementation. Fix up clients. Add missing includes where necessary. Test: m test-art-host Change-Id: I564038d5868595ac3bb88d641af1000cea940e5a
2016-07-01Create a typedef for HInstruction::GetInputs() return type. Vladimir Marko
And some other cleanup after https://android-review.googlesource.com/230742 Test: No new tests. ART test suite passed (tested on host). Change-Id: I4743bf17544d0234c6ccb46dd0c1b9aae5c93e17
2016-06-02Refactor handling of input records. Vladimir Marko
Introduce HInstruction::GetInputRecords(), a new virtual function that returns an ArrayRef<> to all input records. Implement all other functions dealing with input records as wrappers around GetInputRecords(). Rewrite functions that previously used multiple virtual calls to deal with input records, especially in loops, to prefetch the ArrayRef<> only once for each instruction. Besides avoiding all the extra calls, this also allows the compiler (clang++) to perform additional optimizations. This speeds up the Nexus 5 boot image compilation by ~0.5s (4% of "Compile Dex File", 2% of dex2oat time) on AOSP ToT. Change-Id: Id8ebe0fb9405e38d918972a11bd724146e4ca578
2016-04-19Use iterators "before" the use node in HUserRecord<>. Vladimir Marko
Create a new template class IntrusiveForwardList<> that mimicks std::forward_list<> except that all allocations are handled externally. This is essentially the same as boost::intrusive::slist<> but since we're not using Boost we have to reinvent the wheel. Use the new container to replace the HUseList and use the iterators to "before" use nodes in HUserRecord<> to avoid the extra pointer to the previous node which was used exclusively for removing nodes from the list. This reduces the size of the HUseListNode by 25%, 32B to 24B in 64-bit compiler, 16B to 12B in 32-bit compiler. This translates directly to overall memory savings for the 64-bit compiler but due to rounding up of the arena allocations to 8B, we do not get any improvement in the 32-bit compiler. Compiling the Nexus 5 boot image with the 64-bit dex2oat on host this CL reduces the memory used for compiling the most hungry method, BatteryStats.dumpLocked(), by ~3.3MiB: Before: MEM: used: 47829200, allocated: 48769120, lost: 939920 Number of arenas allocated: 345, Number of allocations: 815492, avg size: 58 ... UseListNode 13744640 ... After: MEM: used: 44393040, allocated: 45361248, lost: 968208 Number of arenas allocated: 319, Number of allocations: 815492, avg size: 54 ... UseListNode 10308480 ... Note that while we do not ship the 64-bit dex2oat to the device, the JIT compilation for 64-bit processes is using the 64-bit libart-compiler.

2015-10-08Add DCHECKs to ArenaVector and ScopedArenaVector. Vladimir Marko
Implement dchecked_vector<> template that DCHECK()s element access and insert()/emplace()/erase() positions. Change the ArenaVector<> and ScopedArenaVector<> aliases to use the new template instead of std::vector<>. Remove DCHECK()s that have now become unnecessary from the Optimizing compiler.

2015-09-08Optimizing: Tag basic block allocations with their source. Vladimir Marko
Replace GrowableArray with ArenaVector in HBasicBlock and, to track the source of allocations, assign one new and two Quick's arena allocation types to these vectors. Rename kArenaAllocSuccessor to kArenaAllocSuccessors. Bug: 23736311 Change-Id: Ib52e51698890675bde61f007fe6039338cf1a025
2015-09-03Revert "Optimizing: Tag basic block allocations with their source." Vladimir Marko
Reverting so that we can have more discussion about the STL API. This reverts commit 91e11c0c840193c6822e66846020b6647de243d5. Change-Id: I187fe52f2c16b6e7c5c9d49c42921eb6c7063dba

2015-01-26Optimizing: Speed up HEnvironment use removal David Brazdil
Removal of use records from HEnvironment vregs involved iterating over potentially large linked lists which made compilation of huge methods very slow. This patch turns use lists into doubly-linked lists, stores pointers to the relevant nodes inside HEnvironment and subsequently turns the removals into constant-time operations.

2014-06-06Reduce header files including header files. Ian Rogers
Main focus is getting heap.h out of runtime.h. Change-Id: I8d13dce8512816db2820a27b24f5866cc871a04b
2014-05-16Linearize the graph before creating live ranges. Nicolas Geoffray

2014-05-13Add loop recognition and CFG simplifications in new compiler. Nicolas Geoffray
We do three simplifications: - Split critical edges, for code generation from SSA (new). - Ensure one back edge per loop, to simplify loop recognition (new). - Ensure only one pre header for a loop, to simplify SSA creation (existing). Change-Id: I9bfccd4b236a00486a261078627b091c8a68be33

Also rename accessors to ART's conventions. Change-Id: I344807055b98aa4b27215704ec362191464acecc
2014-03-10Add register support to the optimizing compiler. Nicolas Geoffray
Also make if take an input and build the use list for instructions. Change-Id: I1938cee7dce5bd4c66b259fa2b431d2c79b3cf82

2014-02-19Re-apply: Initial check-in of an optimizing compiler. Nicolas Geoffray
The classes and the names are very much inspired by V8/Dart. It currently only supports the RETURN_VOID dex instruction, and there is a pretty printer to check if the building of the graph is correct. Change-Id: I28e125dfee86ae6ec9b3fec6aa1859523b92a893
