PGO - AArch64 (TCWG-179) (4/10) * Installed QEMU user static for aarch64 and use them from chroot environment in ubuntiu 13.10 * Tried installing chroot + qemu arm64-saucy in another ubuntu 12.04 machine. Issue with binfmts. looks to be corrupted.
* Bootstrap GCC with PGO with --enable-languages=c,c++,fortran completed under arm64-chroot. * Built GCC and binutils in native mode under chroot + qemu arm64-saucy . * SPEC runs -O3 -mcpu=cortex-a57 in chroot + qemu arm64-saucy with linaro release source (4.8). Calculix did not finish under chroot + qemu arm64-saucy GLIBC Systemtap (4/10) * Built systemtap under chroot + qemu arm64-saucy. Built glibc with the patch and used --enable-systemtap. * Able to see setjmp probe in gdb, but longjmp probes not loading. Tried debugging in gdb. gdb debugging support not available yet under qemu. * Discussed with Will newton on my observation. Bug fix (1/10) * Not much progress continued looking at reload dumps. Misc (1/10) * Tested cbuildv2 to build gcc natively under qemu-arm64-chroot-ubuntu-saucy. cbuildv2 reports configure error for gcc and g++multilibs. But they are not needed for native builds. Sent note to Rob for fixing it. * Attend 1-1 with Ryan * Attend 1-1 with Maxim discuss PGO work. == Plan == PGO runs for SPEC2006 on chroot + qemu arm64-saucy Upstream /testing for systemtap probes in glibc Reload bug fix. Leave: 17-Apr local state election. _______________________________________________ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
