Hi,
I tried compiling a hello-world program for cortex -a53/57 but, gcc does not recognize the mcpu option.
Here is my command ...
aarch64-linux-gnu-gcc hello_world.c -mcpu=cortex-a53 -o hello_world
Does the compiler support these options? I see that lib/gcc/aarch64-linux-gnu/4.8.1/plugin/include/config/aarch64/aarch64-cores.def do have the entries for cortex a53 & a57.
Thanks,
Kalai
== Progress ==
* Committed binutils testsuite fix for precise, should be green in cbuild now.
* Comitted binutils fix for ARM IFUNC issue.
* Various small binutils fixes for AArch64.
* Lots of rework of glibc memcpy patch, now up to v6.
* Integrated latest bionic string functions into cortex-strings.
* AArch64 IFUNC code and tests beginning to take shape.
== Issues ==
* None.
== Plan ==
* Another respin of glibc memcpy patch (last one?).
* More work on AArch64 IFUNC.
* May get time to look into gdb bug Peter found.
* 4 day week due to bank holiday.

Progress:
* office move
* checking up on status of licensing issues with QEMU's softfloat
* cleaned up obsolete qemu blueprints in launchpad [Matt G-D is
going to finish the last bits of transferring the backlog to
JIRA where appropriate]
* booked travel/hotel for Connect Dublin
* reviewed John Rigby's mach-virt and aarch64 patches
* VIRT-49
** can run KVM with this code now, need to test migration proper
(requires kernel to support arch timer state save/load),
and clean up some TODOs and other cruft
** GDB is behaving oddly connected to QEMU's stub, which I think is
a GDB bug (LP:1175525) but may also be a QEMU side issue
Plans:
* VIRT-49 debug & patch cleanup
* NB: UK bank holiday next week, will be 3 day week for me
-- PMM
== Issues ==
* None
== Progress ==
* Short week (only 2 days)
* Libunwind AArch64 support:
- Did some fixes and cleanups after review.
- re-submitted upstream
* LRA on ARM and AArch64:
- Enabled LRA on trunk for ARM target
- build doesn't complete, investigation ongoing
* Internal meetings
== Plan ==
* Short week too
* Continue on LRA
== Progress ==
* EuroLLVM 2013
- Conference Mon~Tue
- Analysing questionnaire's response
- Writing a blog entry, reports
* Shorter week, low progress
== Plan ==
* Release
- Start testing version 3.2
- Check-out frozen 3.3 and run the same tests
- Make sure calxeda node is up to the task
- Buy a Chromebook for further testing (?)
I'll probably spend all my time worrying about the release, one way or
another...
Hi,
I'm trying to build the aarch64 tool chain from source on a Redhat machine. I see that build.mk in the crosstool package requires a few .deb packages. If I want to build this on a Redhat machine, what are the changes I have to do?
Thanks,
Kalai
Hi,
I am looking for pre-build (binary, tar) GCC for native ARM e.g. I need to
use in Angstrom FS and panda board to compile the code.
Thanks & regards,

Hi,
I am trying to compile Qt 4.8 for ARMv8. I need following packages.
libqt4-dev libqt4-opengl-dev libphonon-dev libicu-dev libsqlite3-dev
libxext-dev libxrender-dev gperf libfontconfig1-dev libphonon-dev
libpng12-dev libjpeg62-dev
I could not find these or any such packages on Linaro website. Is there any
website which maintains packages compiled for ARMv8?
I downloaded Qt4.8 source code. But it seems I need to do many hacks to get
it compiled for ARMv8. Is it already available some where?
Any help will be appreciated.
Thanks

== Progress ==
* Compared gdb test suite results in arm native none and arm remote
gdbserver configurations. Filled up the googledoc sheet with the
comparison.
* Created a patch for dwarf failures still need to sync it with gdb main
trunk and then need to test it on chrome book and submit after review.
* Investigated gdb.mi test suite failures most of them seems to be occuring
due to long delay. Will retest on chrome book and update.
* Received chrome book on Friday started configuration created a recovery
disk and SD card, facing a kernel panic for now.
* 1:1 with Matt
== Plan ==
* Complete chrome book configuration.
* Run arm test suite in different configurations on chrome book.
* Update the comparison sheet of gdb test suite results in different
configurations after running tests on chrome book.
* Public Holiday on 1st of May
== Progress ==
* AARCH64 - Gprof support.
Make GCC generate profile information (On-going).
Defined hook and macros in GCC to emit "mcount" instrumented calls.
Looked at ARM implementation and veener code in glibc which implements mcount.
Discussed with Matt, and decided to use generic "mcount"
implementation in glibc for aarch64.
The generic uses built_in_return_address. Looking at defining macros
and function which traverses
frames back and returns the desired frame address.
== Plan ==
* Continue gprof support work for Aarch64
Planned leaves:
1 May: Labor Day's holiday.
