Hi all
I am trying to compile poky-dizzy-12.0.1(MACHINE ?= "beaglebone") using
meta-toolchain.
so i downloaded dizzy from
http://downloads.yoctoproject.org/releases/yocto/yocto-1.7.
1/poky-dizzy-12.0.1.tar.bz2
meta-linaro from
https://git.linaro.org/openembedded/meta-linaro.git
I have changed bblayers.conf as below
# LAYER_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly
LCONF_VERSION = "6"
BBPATH = "${TOPDIR}"
BBFILES ?= ""
BBLAYERS ?= " \
/home/praveenk/work/poky-dizzy-12.0.1/meta \
/home/praveenk/work/poky-dizzy-12.0.1/meta-yocto \
/home/praveenk/work/poky-dizzy-12.0.1/meta-yocto-bsp \
/home/praveenk/work/poky-dizzy-12.0.1/meta-linaro/meta-linaro-toolchain \
"
BBLAYERS_NON_REMOVABLE ?= " \
/home/praveenk/work/poky-dizzy-12.0.1/meta \
/home/praveenk/work/poky-dizzy-12.0.1/meta-yocto \
I added required changes in local.conf
MACHINE ?= "beaglebone"
DEFAULTTUNE = "cortexa8hf-neon"
PREFERRED_PROVIDER_glibc ?= "glibc"
PREFERRED_VERSION_gcc ?= "linaro-4.9%"
PREFERRED_VERSION_gcc-cross ?= "linaro-4.9%"
PREFERRED_VERSION_gcc-cross-initial ?= "linaro-4.9%"
PREFERRED_VERSION_gcc-cross-intermediate ?= "linaro-4.9%"
PREFERRED_VERSION_gcc-cross-canadian ?= "linaro-4.9%"
PREFERRED_VERSION_gcc-crosssdk ?= "linaro-4.9%"
PREFERRED_VERSION_gcc-crosssdk-initial ?= "linaro-4.9%"
PREFERRED_VERSION_gcc-crosssdk-intermediate ?= "linaro-4.9%"
PREFERRED_VERSION_gcc-runtime ?= "linaro-4.9%"
PREFERRED_VERSION_nativesdk-gcc-runtime ?= "linaro-4.9%"
PREFERRED_VERSION_libgcc ?= "linaro-4.9%"
PREFERRED_VERSION_nativesdk-libgcc ?= "linaro-4.9%"
PREFERRED_VERSION_gcc-cross-canadian-${TRANSLATED_TARGET_ARCH} ?=
"linaro-4.9%"
but still it is building gcc-4.9 instead of gcc-linaro-4.9
below is the log

* ASAN/TSAN run on 42 bit VA Aarch64 with 64 bit allocators (TCWG-634) (3/10)
Tried various allocator sizes in juno, still fails.
On amd-01, Debugging LLVM test failures in gdb.
* Emails, meetings. (2/10)
* Linaro 1-1 with christophe. status call.

Off sick [4/10]
Backporting [2/10]
. unexpected conflicts and test failures meant that previous attempts
were abandoned
. will try again for 2015.04

. one config failed, restarted in Jenkins
. accessing Jenkins benchmarks still requires help from Bernie due to
permissions
Misc [3/10]
. emails about bugs
. meetings
. verification of lab fixes
== Progress ==
* Linaro bugs (2/10)
#1325
* type promotion pass (zero/sign extension elimination) - TCWG-547 (5/10)
- tried to improve some of the aspects and made it more aggressive
- improved handling of CASE_CONVERT
- tried it on CoreMark and it reduces the number of instructions
in per object file basis.
- bootstrapped the latest improvement on x86-64 and regression tested
on x86-64, ARM and AARCH64. noticed few LTO failures on ARM and AARCH64.
Looking into it.
- Plan to run spec2k again
- Current version at linaro-dev/type-promotion-pass
(https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=refs/heads/linaro-dev/typ…)
