* 4 days week (university).
== Issues ==
* none
== Progress ==
* LRA on AArch32:
o TCWG-343 : Make LRA the default for the ARM backend (3/10)
- Looking backend places (ARM and AArch64) where reload_in_progress
is used to verify if lra_in_progress is needed as well: Tested lot of
configurations, testsuite results analysis ongoing.
o TCWG-345 : Analyse performance of LRA for ARM. (0/10)
- No progress this week.

o Various meetings.
== Next ==
* Child care (chickenpox)
* Still some time spend at university
* Continue on LRA and lib GMP
== Progress ==
* Implemented per process hwbreakpoint and watchpoint cache for arm
native targets.
Also added a reference count for per thread hardware breaks. [TCWG-177] [7/10]
* Travelled to Islamabad for Macau visa application. [3/10]
== Plan ==
* Continue work on forking/vforking hardware breakpoints support for arm-native.
Tweak hardware breakpoint cache and thread breaks reference count to
get it in sync with linux-native. [TCWG-177]
== Misc ==
- Monday 27/01/2014 - Public holiday
== Progress ==
- LP#1191909: gold and -flto always fails with an internal error on
arm-linux-gnueabi* (2/10)
- Reproduced it and Looking into the implementation for best fix.
-c11-atomic-exec-5.c (4/10)
- Issue is due to missing target hook and looking at implementing
-LP#1270789: gcc 4.8: "invalid expression as operand" in aarch64
inline asm (2/10)
- came-up with the patch. Still in the process of testing it. APM1
disc seems to be corrupt and that is holding this.
- Benchmarking (1/10)
- added -pgo for coremark
- Set-up a Linux desktop (1/10)
== Plan ==
- Continue with trunk daily regression
- Fix assigned bugs
== Progress ==

* Meetings. (1/10)
* Started reviewing Kugan's benchmarking branch of Cbuildv2. (1/10)
== Plan ==
* Build static gdbserver for target via Cbuildv2.
* Add Win32 installer for Canadian cross built binary
releases to Cbuildv2. (TCWG-381)
* Once Jenkins has a node_selector for the new Beagle Board Blacks,
get those working for native builds. (TCWG-379)
* Get QEMU and Foundation Model running on TCWG x86_64 build slaves
so Jenkins can use them for native builds. (TCWG-380)
== Progress ==
* Add support for AArch32 ARMv8 16<->64bit VCVT to QEMU (2/10, TCWG-51)
* Triage and report AArch64 gcc bug when building glibc with SystemTap (1/10)
* Debug and submit patch for ARM libffi issue (1/10)
* Add support for longjmp/setjmp Systemtap probes on ARM (4/10, TCWG-378)
* Ported Python cffi package to AArch64, submitted upstream (1/10)
* Fixed bug building glibc for armv4 (1/10)
== Issues ==
* Broadband down for 3 hours on Wednesday afternoon
== Plan ==

== Progress ==
* Compiler-RT
- Changing CMake to make it compile on ARM
- Reviewing long div/mod patches for ARMv4/v5/v6, testing and benchmarking
* EHABI
- Investigating EH code generation (landing pads, jump tables, libs)
- Running test-suite EH tests, some failures
* Background
- Loads of patch reviews on IAS, build attributes, EHABI, compiler-rt
- Planning the 3.4.1 release (the first patch-release of LLVM)
* Time
- CARD-862 8/10
- Others 2/10
== Plan ==
* Continue EHABI tests, try to turn it on by default
* Continue working on RT's CMake for ARM
* Prepare the FOSDEM 14 presentation
== This week ==
- Completed merge of crypto backports from trunk to Linaro 4.8 branch:
- 64-bit backports: 205092, 205383, 205384, 206114, 206115, 206117, 206118,
206149
- 32-bit backports: 206518 AND 206519
- Built and tested 32 and 64-bit compilers with crypto changes
== Next week ==
- Submit backports for review using git review
- New backports
== Future ==
== Progress ==
Deferred US Holiday (MLK day) from Monday to Tuesday
* Debugged what was thought to be a cbuild2 problem but ended up being
due to default enablement of multilib in gcc. (2/10)
* Started working on adding mulit-lib support to cbuild2 (minimal
configuration for installing headers). (8/10) [Jira card forthcoming]
- Moved kernel headers installation to arch based directory in
sysroot and then symlinked appropriate host include directories to
common arch directories.
- Figured out how to build multilib arm libraries for
arm-none-linux-gnueabihf and arm-none-linux-gnueabi.
== Plan ==
* Add cbuild2 scripting to build multilib libraries based on gcc
-print-multi-lib
* Figure out how to get gcc to select the correct multilib headers
directory so that we don't need a merged include directory.
== Issues ==
* None
The Linaro Toolchain Working Group is pleased to announce the
release of both Linaro GCC 4.7 and Linaro GCC 4.8.
As announced at Linaro Connect USA 2013 Linaro GCC is moving to a
pattern of quarterly stable releases, with engineering releases in the
intervening months. This is the first stable release, and contains no
known regressions compared to the 2013.12 release.
The next release of GCC 4.7 will be the 2014.04 stable release. There
will be no engineering releases of GCC 4.7 in 2013.02 or 2013.03.
The next stable release of GCC 4.8 will be the 2014.04 release. Next
month's release - 2013.02 - will be an engineering build.
Linaro GCC 4.7 2014.01 is the twenty second release in the 4.7
series. Based off the latest GCC 4.7.4+svn206380 release, this is the
ninth release after entering maintenance.
Interesting changes include:
* Updates to GCC 4.7.4+svn206380
Linaro GCC 4.8 2014.01 is the tenth release in the 4.8 series. Based
off the latest GCC 4.8.3+svn206350 release, it includes performance
improvements and bug fixes.
Interesting changes include:
* Updates to GCC 4.8.3+svn206350
* Enhanced multilib support
