VAR_CPU_ARCH for ARM platforms
by Bob Vandette 28 Jan '16

28 Jan '16

In my push to the mobile/dev forest, I changed VAR_CPU_ARCH on arm platforms to always use arm for both 32 and 64 bit arm builds to be consistent with the setting for x86/x86_64. http://cr.openjdk.java.net/~bobv/8145936/webrev.00/ <http://cr.openjdk.java.net/~bobv/8145936/webrev.00/> My assumption which is confirmed by most of the usage in the makefiles is that VAR_CPU_ARCH should be set to the generic ARCH family (x86, arm) for both 32 and 64 bit builds. My motivation for doing this was initially for the selection of the Socket and UnixConstant template files used in cross compilation since these files contain the same content for arm and aarch64. This seems to be causing at least one problem in the hotspot build where in JDK 9, ARCH is being set to VAR_CPU_ARCH (via OPENJDK_TARGET_CPU_ARCH). For aarch64 builds, ARCH gets set to arm. In JDK8, ARCH is set to VAR_CPU and not VAR_CPU_ARCH. Was there a reason for this change? Can we go back to the way it was in JDK8???? There are a lot of hacks in both open and closed makefiles to set various variable based on ARCH in order to end up with the correct variables. In hotspot/make/defs.make, we undo the VAR_CPU_ARCH setting of x86 for x86_64 builds by checking for LP64! This is not done for arm. BUILDARCH ?= $(SRCARCH) ifeq ($(BUILDARCH), x86) ifdef LP64 BUILDARCH = amd64 else BUILDARCH = i486 endif endif in hotspot/make/closed/defs.make, we don't fix this issue either. ifeq ($(ARCH), arm) SRCARCH = arm LIBARCH = arm ARCH_DATA_MODEL = 32 PLATFORM = linux-arm VM_PLATFORM = linux_arm HS_ARCH = arm endif ifeq ($(ARCH), aarch64) BUILDARCH = aarch64 SRCARCH = arm LIBARCH = aarch64 HS_ARCH = arm SAARCH = arm64 endif

RFR: Backports to jdk8

22 Jan '16

Hi, I would like to backport the patches changesets below from jdk9 to jdk8. I have tested server and client builds and also a server slowdebug build. The following are the jtreg results for hotspot and langtools from the server-release build (results before and after were identical). Hotspot: Test results: passed: 675; failed: 17; error: 3 Langtools: Test results: passed: 3,091 OK to push?
