2017-01-15Revert "Revert "ART: Compiler support for invoke-polymorphic.""Orion Hodson
This reverts commit 0fb5af1c8287b1ec85c55c306a1c43820c38a337. This takes us back to the original change and attempts to fix the issues encountered: - Adds transition record push/pop around artInvokePolymorphic. - Changes X86/X64 relocations for MacSDK. - Implements MIPS entrypoint for art_quick_invoke_polymorphic. - Corrects size of returned reference in art_quick_invoke_polymorphic on ARM. Bug: 30550796,33191393 Test: art/test/run-test 953 Test: m test-art-run-test Change-Id: Ib6b93e00b37b9d4ab743a3470ab3d77fe857cda8
2017-01-11Revert "ART: Compiler support for invoke-polymorphic."Orion Hodson
This reverts commit 02e3092f8d98f339588e48691db77f227b48ac1e. Reasons for revert: - Breaks MIPS/MIPS64 build. - Fails under GCStress test on x64. - Different x64 build configuration doesn't like relocation. Change-Id: I512555b38165d05f8a07e8aed528f00302061001
2017-01-11ART: Compiler support for invoke-polymorphic.Orion Hodson
Adds basic support to invoke method handles in compiled code. Enables method verification for methods containing invoke-polymorphic. Adds k45cc/k45rc output to Instruction::DumpString() which was found to be missing when enabling verification. Include stack traces in test 957-methodhandle-transforms for failures so they can be easily identified.

2016-11-21ART: Add dex::TypeIndexAndreas Gampe
Add abstraction for uint16_t type index. Test: m test-art-host Change-Id: I47708741c7c579cbbe59ab723c1e31c5fe71f83a
2016-08-30ART: SHARED_REQUIRES to REQUIRES_SHAREDAndreas Gampe
This coincides with the actual attribute name and upstream usage. Preparation for deferring to libbase. Test: m Test: m test-art-host Change-Id: Ia8986b5dfd926ba772bf00b0a35eaf83596d8518
2016-07-27ART: Delete old compiler_enums.hAndreas Gampe
Holdover from the Quick days. Move the two enums that are still used closer to the actual users (and prune no longer used cases). Test: m test-art-host Change-Id: I88aa49961a54635788cafac570ddc3125aa38262
2016-06-08Do not place null check on unresolved method calls.Aart Bik
Rationale: These invokes drop through the runtime anyway where various checks are done, including null check. A few of these checks need to occur before the null check. With fail-before/pass-after smali test. BUG=29068831 Change-Id: I260715e742365433a323598d97f7fdab321e8512
2016-04-22ART: Naive NullCheck elimination in InstructionBuilderDavid Brazdil
Save a little bit of memory by not generating trivially redundant HNullCheck instructions. This patch builds on the fact that the InstructionBuilder now directly generates SSA form and looks at the input of the NullCheck. For obvious cases, such as NewInstance/Array or `this`, the NullCheck generation is completely avoided. Bug: 28173563 Change-Id: I1fdf3b096c7a939f7b8586c02a2a6b44dfa43443
2016-04-14Use dex cache from compilation unit in HInstructionBuilder.Vladimir Marko
Avoid calling costly ClassLinker::FindDexCache() from HInstructionBuilder, the dex cache is already available in the compilation unit. Compiling Nexus 5 boot image on host under perf(1) shows that the time spent in FindDexCache() is reduced from about 2% to well under 0.2%, 90% of the remaining hits coming from ReferenceTypePropagation which doesn't have access to the compilation unit.

2016-04-07Revert "Revert "Refactor HGraphBuilder and SsaBuilder to remove HLocals""David Brazdil
This patch merges the instruction-building phases from HGraphBuilder and SsaBuilder into a single HInstructionBuilder class. As a result, it is not necessary to generate HLocal, HLoadLocal and HStoreLocal instructions any more, as the builder produces SSA form directly. Saves 5-15% of arena-allocated memory (see bug for more data): GMS 20.46MB => 19.26MB (-5.86%) Maps 24.12MB => 21.47MB (-10.98%) YouTube 28.60MB => 26.01MB (-9.05%) This CL fixed an issue with parsing quickened instructions.
