Description Xerxes Rånby 2016-02-29 11:06:41 CET

General purpose ARM 64bit GNU/Linux systems are now cheaply available with various GPU configurations.

JogAmp buildfarm need to build linux-aarch64 GNU/Linux AArch64 natives into gluegen and all modules in order to support these new boards and system configurations.

 Bug 1295: Add linux-aarch64 GNU/Linux AArch64 crosscompile support

make/lib/gluegen-cpptasks-linux-aarch64.xml:
  Add missing -DisLinux=true required when crosscompiling
  Remove -marm -mfloat-abi=hard flags unrecognisable by aarch64 crosscompile toolchain

make/lib/toolchain/aarch64-linux-gnueabi/bin/*:
  Symlink to /usr/local/x-tools/aarch64-unknown-linux-gnueabi/bin/aarch64-unknown-linux-gnueabi-*

make/scripts/make.gluegen.all.linux-aarch64-cross.sh:
  New crosscompile script

make/stub_includes/platform/glibc-compat-symbols.h:
  glibc 2.17 is the first glibc version that support aarch64
  however memcpy is not versioned for aarch64
  Disable versioning for linux glibc/aarch64

Comment 3 Xerxes Rånby 2016-12-12 09:11:18 CET

Created attachment 794 [details]
aarch64-libc-2.18-versioned-symbols.log

Attached logfile from aarch64 crosstools-ng crosscompile toolchain with versioned symbols support indicating that memcpy is not versioned despite that versioned symbols down to 2.17 is included. This is the reasion to disable versioned symbols for memcpy on linux glibc aarch64.
