The Linaro Toolchain Working Group is pleased to announce the release of
Linaro QEMU 2013.06.
Linaro QEMU 2013.06 is the latest release of qemu-linaro. Based off
upstream (trunk) QEMU, it includes a number of ARM-focused bug fixes
and enhancements.
This release has been updated to be based on upstream's recent 1.5.0
release. Interesting ARM related upstream changes include fixes to
the VersatilePB and Realview model PCI controller, improved performance
of emulation of ARM targets, and working VM save/load for vexpress-a15
and vexpress-a9 board models.
The source tarball is available at:

== Progress ==
* Merges for linaro-4.8-2013.06 and linaro-4.7-2013.06
- Spent most of my time on this activity, with Yvan
- A few cbuild issues, local disk full, and other local disk crash
- Investigating why the cross-validations lack libpthread and libdl
(required since libsanitizer backport). The libs are present, but not
found by the compiler.
* Registered for Connect/Dublin
== Next ==
* Complete merges quickly, to enable release this week.
* Disable-peeling: resume work
* Better end of loop counter optim: discuss with Kugan
* libsanitizer/aarch64: resume work
* Neon intrinsics/vzup/veor: resume work
* Book hotel/flight for Connect/Dublin
== Issues ==
* None.
== Progress ==
* Releases merge reviews:
- Most of the week spent on this activity
- Lot of reviews and cbuild issues
- some reviews still on-going
* Jira cards:
- Closed card #108 on Tiny memory model support.
- Created Card #167 for TLS support in the Tiny memory model.
* LRA on ARM and AArch64:
- Raise the issue to LRA maintainer (Vladimir Makarov)
- will iterate with him in the coming weeks.
* Launchpad bug #1187247
- started to look at it.
== Plan ==
* Finishing reviews
* Bug #1187247
* LRA
== Progress ==
* AARCH64 testing
Drilling down Boot strap failure with GCC 4.9 trunk on open embedded
image with V8 model
Sent the steps to reproduce boot strap failure in the model to team.
Renoto suggestion to add libgcc_eh.a explicilty is not working well at
all places.
Trying few other options (LDFLAGS, --with-stage1-libs ) to pass
libgcc_eh.a to the xg++ build.
* libssp support for Aarch64
Wrote down the steps needed to implement the support in Aarch64. Sent
mail to Matt for a review.
Working on machine descriptions for stack_protect_set and stack_protect_test.
* Filled online VISA Application form. Collected Relevent documents needed.
Hotel rooms are not available via online booking. Sent follow up mail
to the hotel and informed James and Arwen.
== Plan ==
* Continue bootstrap testing and push patches to GCC
* Implement Libssp GCC back end hooks.
* Linaro connect travel prep, book tickets hotel and apply visa.
== Progress ==
* Did builds of GCC 4.6, 4.7, 4.8, 4.9-svn on x86_64, i686, arm7l to
load more recent data into testing database plus test source builds
for the release at the same time.
* Did builds of GDB 7.6 & 7.5 on x86_64, i686, arm7.
* Added wiki page on how to run DejaGnu in a chroot.
* Cbuildv2 work continuing, works well enough to do the above
builds plus bootstrapping infrastructure.
* Change how the index for the testing database gets calculated,
so it's now possible to delete bogus records without screwing
up existing data when importing.
== Plan ==
* Produce some new graphs with the data from the above builds and
test runs.
* Make GCC & GDB release tarballs.
* Update wiki pages on Cbuildv2, release process.
== Issues ==
* Figure out why make check for GDB fails for everything on
chromebook running 13.04.
- rob -
== Progress ==
* Investigated gdb.threads and gdb.multi failures and submitted patch
to enable tests requiring multiple hardware breakpoints on arm
targets.
* Investigate gdb.base failures and submitted patch to enable
disp-step-syscall.exp for arm targets.
* Investigate gdb.mi and gdb.trace failures, some of problems are
feature requests on arm.
* Investigate gdb.base failures and submitted patch to enable
disp-step-syscall.exp for arm targets.
* Submitted gdb.dwarf2 pending patch.
== Plan ==
* Try to fix remaining gdb failures.
* Generate a fresh copy of gdb test suite results on arm and x86
* Chromebook os update on a faster sd card.
* Add JIRA cards for gdb features missing on arm.
* Follow up on Ireland visa application.
== Progress ==
* Better end of loop counter optimisation
- Experimented with fixing the extra instruction.
- Found a possible way to fix it. Discussing it with Christophe.
* Generate a single call to divmod
- Looked at the code including how sin()/cos() -> sincos() handling
in gcc.
- Implemented a prototype and experimented.
== Plan ==
* VRP based zero/sign extension
- Ping the patch.
* Generate a single call to divmod.
- Finish the prototype implementation and get the regression working
- Discuss in gcc mailing list for a good way to implement and get
consensus with the results from prototype.
== Issues ==
* None
== Progress ==
* Test and send out shrink wrapping improvement patch for review (TCWG-133).
* Update aarch64-none-elf TARGET_CFLAGS to " -g -O2 ".
* Enable aarch64 gdb build for Windows (lp:1187862).
* Investigate conditional compare RTL representation.
- Trying to expand it to cmp_and/cmp_ior like instruction.
== Plan ==
* Continue on conditional compare.
== Planed leaves ==
* June 10-12: Dragon Boat Festival.
