== Progress ==
* Fixed remaining issues in rework of hwbreakpoint and watchpoint
implementation for arm
native targets. Tested and submitted patch. [TCWG-177] [8/10]
* Installation and Setting up of new desktop machine. [2/10]
== Plan ==
* Run testsuites to see current status of arm gdb.
* Follow up on submitted patches.
* Public holiday on Wednesday 5th February.
* Libsanitizer for AArch64: (4/10)
- seems to be mostly working, but trouble with validation both using
the Foundation Model and qemu-aarch64.
- Some tests seems to loop forever while unwinding under qemu, but
run fine under the Foundation model
- Conversely the Foundation Model shows some random errors, and the
corresponding tests pass under qemu
- Some random timeouts with the Foundation Model, despite using ssh
multiplexing
- Added a small patch to qemu to hande missing mmap flag. Need to
send upstream.
- asked Rob to run GCC testsuite with my patch on AArch64 but it's
too unstable these days
* Cross-validation (2/10)
- script now able to validate a GCC patch and compare results with
unmodified GCC trunk
- added arm-none-eabi target
- using qemu-aarch64 for aarch64-none-linux-gnueabi but the
validations now time out. Need investigation, but I might have to
revert to no execution for this target.
- identified a problem with the recent armv7-ve patch
* Benchmarks: (1/10)
- collecting data for 4.8 tables
* Peeling: (1/10)
- backported new vectorizer cost model to check it if's OK to
include it in our next release
* Misc (2/10): conf-calls, meetings, docs (howtos for TCWG)
== Next ==
* libsanitizer on AArch64
* fix cross-validation on aarch64-none-linux-gnu
* benchmarks: complete table
* backports: chek new vectorizer cost model, monthly branch merge,
review Michael's backports of Crypto intrinsics
* 2 days week (university & child care).
== Issues ==
* none
== Progress ==
* LRA on AArch32:
o TCWG-343 : Make LRA the default for the ARM backend (0/10)
- No progress this week
o TCWG-345 : Analyse performance of LRA for ARM. (1/10)
- Configured and ran benchmarks on Cortex-a15.
* Looked at Linaro 4.8 release performance on Cortex-a15. (2/10)
* Misc. (1/10)
o Booked Hotel and flight for connect
== Next ==
* Back on LRA and lib GMP
== Progress ==
* Investigate "PGO" for Aarch64 (3/10).
Bootstap testing aarch64 with PGO for GCC.Stage 2, feedback profile in progress.
Tested a small test case for -fbranch-probabilities, works same as x86_64.
Working on checking the "gcda" files generated and profile runs for coremark.
* Cbuild2 discussed with rob, ryan on using cbuild2 for developement. (3/10)
Thanks Rob for fixing some issues and adding features that I
requested. Tested some features added. Captured it as FAQ.
* Reinstalled ubuntu OS on my laptop (2/10)
Misc (2/10)
-------------
AMD internal meetings and did some investigations
== Plan ==
- Continue run EMBCC and coremark benchmarks with -PGO enabled.
- Going on marriage vacation from 07-Feb till 06 March
== Issues===
Follow up upstream libssp GCC discussions. No response yet after 2 pings :(
== Progress ==
* Got binary release building working again. (2/10)
* Added a node_selector to Jenkins for the new Beagle Board Blacks, and
get those working for native builds. (TCWG-379, 1/10)
* Fix configuration of 'build-all' project in Jenkins, now fires up
cross builds for supported targets, plus native builds on
Chromebooks and Beagle Board Blacks. (1/10)
make networking route externally. (TCWG-380)
* Meetings and Misc. (3/10)
* Got TCWG build farm, all nodes offline fixed.
* Wrote wiki page on the build farm.
* Updated Java to 1.6 on the Beagle Board Blacks in the TCWG
build farm.
* Added support to specify an alternate prefix for installation.
* Got QEMU and Foundation Model running on TCWG x86_64 build slaves
so Jenkins can use them for native builds. (TCWG-380 - 2/10)
* Got Rasberry PI softfp image running under QEMU, tried to do
build. (TCWG-380 - 1/10)
== Plan ==
* Build static gdbserver for target via Cbuildv2.
* Add Win32 installer for Canadian cross built binary
releases to Cbuildv2.
* Get Kugan's benchmark branch running on build farm.
* More Jenkins maintainance.
== Potential Leave ==
* Still working out the huge amount of details, but strongly
considering going to Mt Everest after Connect. It'd be a long and
rough trip, but a once in a lifetime opportunity.
== This week ==
- Successfully submitted crypto using git-review
- Completed merge of ILP backports from trunk to Linaro 4.8 branch: 201164,
201165, 201166, 201167, 201168, 201170 and 201175
- Attended ARM architecture training on Friday
== Next week ==
- Submit ILP backports for review using git review
- New backports
== Future ==
== Progress ==
* Rework QEMU patch for AArch32 ARMv8 16<->64bit VCVT (2/10, TCWG-51)
* Further work on longjmp/setjmp Systemtap probes on ARM (4/10, TCWG-378)
* Research and analysis of malloc workloads for benchmarking (4/10, TCWG-160)
== Issues ==
* None
== Plan ==
* Finish testing setjmp/longjmp changes
* malloc benchmarking and improvements
