Toolchain Working Group, Linaro
[very short week; two days]
Progress:
* misc
** made qemu-linaro 2013.06 release
** remaining VIRT-4 work handed over to other people for now
** Huawei's AArch64 TCG patches now committed upstream
** working through mach-virt and virtio patches to see what
still needs to be done here and in what order
Plans:
* continue mach-virt/virtio work
* set up a new qemu-linaro tree/branch as our CI/LAVA input [to keep it
separate from our "we release this" tree]
* restart work on upstreaming omap3 patches as part of my generic qemu
maintenance work (will reduce our maintenance burden in the long term)
-- PMM
== Progress ==
* Pandaboard
- Using GNU ld didn't help the problem, and made compilation time double
to 5hs!
- Reverting to Gold and will keep an eye on it
* Release 3.3 finished
- Tested and released, just waiting the final email
* Linaro+ARM sync meeting
- Setting priorities, requesting approval for some work items
* Phoronix
- Script to run batch mode ready at:
http://people.linaro.org/~rengolin/llvm/scripts/
- Got some results, generally on par, some big differences could be due to
compilation options
- Some tests still run GCC, even with CC being Clang, Clang-only options
(slp vect) cannot be tested
- No way yet to share this data internally, working with IT to find a
solution
* CBuild
- Merged Clang changes, running job again
- Autodetecting ARMv7
* LLVM administrativia
- many patches to review this week
- vectorizer also being enabled by default on -O2 and -Os
- testing vectorizer with -Os on chromebook, found no big differences
== Issues ==
None
== Plan ==
* Phoronix
- Store the base runs somewhere (people.linaro?) and have the script
install them to compare with any run on the board.
- Think of a way to put bootstrap & phoronix in LAVA/CBuild (whatever is
easier), so I can use the calxeda nodes without worry if they'll be up or
down
* Pandaboard
- Use GCC 4.8 on linaro-panda-02 and hope to solve the problem
* CBuild
- Finish LLVM+Clang change (merge pending) and try to run some benchmarks
with it
* PerfDB
- Install website locally, try to cook some analysis
