Hi all My purpose it to build JDK 11 Portola for ARM64 arch, I'm using x86 as a build arch,
1. The boot SDK is built from the same source. 2. The cross compile toolchain is gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu 3. The build is done in Alpine OS with glibc on it. My configure command looks ./configure --openjdk-target=aarch64-oe-linux --with-boot-jdk=/work/jdk11/build/linux-x86_64-normal-server-release/jdk --with-devkit=/tools/aarch64-toolchain/gcc-linaro-7.3.1-2 018.05-x86_64_aarch64-linux-gnu --disable-warnings-as-errors --disable-sjavac The configure output has only one warning *WARNING: using cross tools not prefixed with host triplet* which I can't resolve. now when I try to run the make command I'm getting the following error /Compiling 3 files for BUILD_VM_COMPILER_MATCH_PROCESSOR Compiling 5 files for BUILD_VM_COMPILER_NODEINFO_PROCESSOR Compiling 3 files for BUILD_VM_COMPILER_OPTIONS_PROCESSOR Compiling 14 files for BUILD_VM_COMPILER_REPLACEMENTS_PROCESSOR Compiling 3 files for BUILD_VM_COMPILER_SERVICEPROVIDER_PROCESSOR Compiling 188 files for BUILD_jdk.rmic.interim Compiling 162 files for BUILD_TOOLS_JDK /work/jdk11/src/hotspot/os_cpu/linux_aarch64/copy_linux_aarch64.inline.hpp: Assembler messages: /work/jdk11/src/hotspot/os_cpu/linux_aarch64/copy_linux_aarch64.inline.hpp:116: Error: no such instruction: `prfm pldl1strm,[%rdi,' /work/jdk11/src/hotspot/os_cpu/linux_aarch64/copy_linux_aarch64.inline.hpp:118: Error: no such instruction: `adr %rax,0f' /work/jdk11/src/hotspot/os_cpu/linux_aarch64/copy_linux_aarch64.inline.hpp:118: Error: number of operands mismatch for `add' /work/jdk11/src/hotspot/os_cpu/linux_aarch64/copy_linux_aarch64.inline.hpp:125: Error: no such instruction: `prfm pldl1strm,[%rdi,' /work/jdk11/src/hotspot/os_cpu/linux_aarch64/copy_linux_aarch64.inline.hpp:127: Error: no such instruction: `adr %rax,0f' /work/jdk11/src/hotspot/os_cpu/linux_aarch64/copy_linux_aarch64.inline.hpp:127: Error: number of operands mismatch for `add' make[3]: *** [lib/CompileJvm.gmk:156: /work/jdk11/build/linux-aarch64-normal-server-release/hotspot/variant-server/libjvm/objs/accessBackend.o] Error 1 make[2]: *** [make/Main.gmk:257: hotspot-server-libs] Error 2 make[2]: *** Waiting for unfinished jobs.... / I know it's related to the cross compile process, pls help me to fix it. -- Sent from: http://openjdk.5641.n7.nabble.com/OpenJDK-Build-Infrastructure-f75522.html
