[OpenJDK8u] java.nio.Bits.unaligned() doesn't handle aarch64
by White, Derek 14 Aug '17

14 Aug '17

In aarch64-port/jdk8u, java.nio.Bits.unaligned() only returns true for x86(s). This ends up being important because Apache Spark uses Bits.unaligned() to decide if it can use off-heap memory or not. In mainline jdk8u, this was updated to include PPC as well (See https://bugs.openjdk.java.net/browse/JDK-8165231) JDK9 has a much better fix that supports aarch64 already. Tested on Spark and off-heap memory was being used. Note: The PPC fix also patched sun/security/provider/ByteArrayAccess.java, but I didn't include this in the patch below (not sure if it matters, or how to test it). This is my first attempt at an aarch64-jdk8u patch. Please let me know if I'm not following protocol correctly. Thanks, - Derek Patch follows (in jdk/src). --- old/src/share/classes/java/nio/Bits.java 2017-05-11 13:10:31.916219496 -0400 +++ new/src/share/classes/java/nio/Bits.java 2017-05-11 13:10:31.832221728 -0400 @@ -614,7 +614,9 @@ String arch = AccessController.doPrivileged( new sun.security.action.GetPropertyAction("os.arch")); unaligned = arch.equals("i386") || arch.equals("x86") - || arch.equals("amd64") || arch.equals("x86_64"); + || arch.equals("amd64") || arch.equals("x86_64") + || arch.equals("ppc64") || arch.equals("ppc64le") + || arch.equals("aarch64"); unalignedKnown = true; return unaligned; }

Backports from jdk9 to aarch64-port/jdk8u
by Stuart Monteith 11 Aug '17

11 Aug '17

Hi, I've been working on some aarch64 patches that should be backported from jdk9 to aarch64-prot/jdk8u. I've backported the following stack of patches, and I'm currently testing with them. Do these look sensible? Are there other I should consider, that are not specifically AArch64? I've put in 8175887 as it obviously affects JCStress. I've excluded patches that are obviously not applicable to JDK8u - Graal, for example. 8175887: C1 value numbering handling of Unsafe.get*Volatile is incorrect https://bugs.openjdk.java.net/browse/JDK-8175887 http://hg.openjdk.java.net/jdk9/dev/hotspot/rev/2ff05d967fb2 This isn't strictly an aarch64 issue, but is causing JCStress to fail. 8173472: AArch64: C1 comparisons with null only use 32-bit instructions https://bugs.openjdk.java.net/browse/JDK-8173472 http://hg.openjdk.java.net/jdk9/dev/hotspot/rev/b53b0251e250 This is a fix for a serious bug that was causing spurious failures. 8172881: AArch64: assertion failure: the int pressure is incorrect https://bugs.openjdk.java.net/browse/JDK-8172881 http://hg.openjdk.java.net/jdk9/dev/hotspot/rev/bfa8e4b0d4e2 Was causing a SIGSEGV. 8171537: aarch64: compiler/c1/Test6849574.java generates guarantee failure in C1 https://bugs.openjdk.java.net/browse/JDK-8171537 http://hg.openjdk.java.net/jdk9/dev/hotspot/rev/a3bd5804b4be 8171410: aarch64: long multiplyExact shifts by 31 instead of 63 https://bugs.openjdk.java.net/browse/JDK-8171410 http://hg.openjdk.java.net/jdk9/dev/hotspot/rev/da52f1047024 Fixes a bug that was causing a slow path to be executed by mistake.

RFR: 88158361: AArch64: Address calculation missed optimizations
by Zhongwei Yao 26 Jul '17

26 Jul '17

Hi, all, A missing rule (AddExtL_sxtw_imm) to match following test Java code is added in this patch: z = y + (((long)x) << 2) // where x is int, y is long, const number (2) can be in range [0, 4] inclusively. C2 generated following code before applying patch below: sbfiz x10, x1, #2, #32 add x0, x2, x10 So after applying this patch, C2 generates: add x0, x2, w1, sxtw #2 And typically, Java code involving Unsafe address calculation will match this rule: x = unsafe.getAddress(mem) + (((long)i) << 3) // where i is int By the way, the counterpart sub extension rule (like SubExtL_sxtw_imm) is also missing. And moreover, other add/sub extension rules (like AddExtL_uxtb_and_shift, AddExtL_uxth_and_shift etc.) are also missing. But these rules are not hit at all in my real world benchmark tests. I feel they are too specific to be matched. So I do not include them in my patch. And I found JDK-8158361 fit my fixing. If you feel it may not be appropriate, I can create a new one for this patch. Bug: https://bugs.openjdk.java.net/browse/JDK-8158361 Webrev: http://cr.openjdk.java.net/~njian/8158361/webrev.00/ Please help to review it. -- Best regards, Zhongwei

RFR: 8182583: AArch64: FMA Vectorization on aarch64
by Yang Zhang 30 Jun '17

30 Jun '17

Hi Andrew Vector FMA instructions for X86 have been enabled in jdk10. This patch is to enable vector FMA for aarch64 jdk10. The jtreg is passed and there isn't new failed test. With this patch, vector FMA instructions (fmla/fmls) can be generated. And there is obvious performance improvement (2~3.6 times faster using jmh microbenchmark). Webrev: http://cr.openjdk.java.net/~njian/8182583/webrev.00/ Bug: https://bugs.openjdk.java.net/browse/JDK-8182583 Would you please help to review it? Regards, Yang

RFR: fix for crash caused by earlyret of compiled method
by Sergey Nazarkin 27 Jun '17

27 Jun '17

Hi! Please review the fix [1] for the crash happens when compiled method is forced to return early. We found this issue when running vm/jvmti/ForceEarlyReturnObject/fero001/fero00103/fero00103.html JCK test on CPU with 47 cores. The crash happens at the time when test code tries to check returned value and gets invalid oop. Despite correct object was acquired by load_earlyret_value(), it is accidentally substituted on the stack when remove_activation() is executed (see TemplateInterpreterGenerator::generate_earlyret_entry_for). Substitution, in turns, happens due to overlapping of expression and native stacks. Particularly esp equals to sp because frame with no expression is restored (that is correct). After that execution of following code sequence replaces TOS with some irrelevant value. push(tos) // -> puts value on expression stack unlock_object() // -> calls call_VM() and save registers on native stack, in fact, at the same place as esp pop(tos) // -> restores invalid value The fix restores expression stack to max possible for deoptimized method size. Please consider if this fix covers the case workarounded by [2] (I was not able to trace back and find the reason for this changeset). [1] http://cr.openjdk.java.net/~snazarki/earlyret_crash/ [2] http://hg.openjdk.java.net/aarch64-port/jdk8u60/hotspot/file/83f5fdfd56ec/s… Sergey Nazarkin

Backport patches for 8031818, 8139758 and 8144993
by Felix Yang 19 Jun '17

19 Jun '17

Hi, Please review: http://cr.openjdk.java.net/~fyang/8u-backports/webrev/ This backport three patchs: 8031818, 8139758 and 8144993 to jdk8u aarch64 port. I think It's necessary for this repo to have the last two patches. I backport the first one as the second one depends on it. We see some performance gain for one of our real world Java application. Tested with JTreg on aarch64 Linux platform, OK to push? Felix, Thanks
