cbuild2 benchmarking - TCWG-360 [7/10]
* Fixed/worked around some especially resilient bugs
** Mostly relate to running benchmarks through LAVA, which may be less
important in the near future
* Wrote a doc
* Upstreamed some code that works about as I want it to
Meetings/mail/etc [3/10]
=Plan=
cbuild2 benchmarking
* Work through TODO list from connect
* Tidy up behaviour on shutdown
* Storage issues
* (Maybe) persuade a LAVA Juno to work for benchmarking or configure spec
Hopefully pick up something else
= Progress ==
* Core mark benchmark and report for PGO and PGO + LTO (4/10)
More profiling and collected numbers and reported. JIRA card TCWG-181 updated.
Adding LTO gains in x86 and degrades in Aarch64 .
* Addressed machine bring up issues, debugged and installed necessary
packages for both x86 and Aarch64 (1/10)
* PR 62308 - Analyzed RTL dumps. Looks to be similar issue solved in
trunk. Git bisected and found the passing revision in trunk. posted my
comments. waiting for feedback. (2/10)
* Misc [3/10]
Internal work, emails, AMD meetings and 1-1 with inline manger.
1-1 with Maxim, christophe and 1-1 with ryan
Linaro status call
== Plan ==
* Coremark benchmark and profiling for PGO and PGO + LTO. Investigate
LTO degradation causes and report.
* Investigate PR 63173
* Setup Cbuildv2 build in internal machine.
== Issues ==
Experiencing Hardware connection issues and kernel instability issues
with my local machines.
== Holiday ==
* Public Holiday (2/10)
* Leave (4/10)
== Progress ==
* Zero/sign extension elimination with widening types (4/10)
- Started experimented with a pass for widening type.
- Verified for one simple test-case.
- Bootstrapping is failing and looking into it.
== Plan ==
* Continue with Zero/sign extension pass.
== Progress ==
* Automation Framework (CARD-1378 1/10)
- Planning LAVA server for new TCWG gateway
* Buildbots (TCWG-76 7/10)
- Fixing Compiler-RT buildbot (from 69 to 4 failures)
* Background (2/10)
- Code review, meetings, discussions, etc.
- Re-testing a change in inst combine that broke bots before
- Reviewing CMake builder for Windows builds
- Discussing clang-reformat on lld's codebase
== Plan ==
* Continue fixing the Compiler-RT buildbot
* Present 2 talks at Linux Plumbers
== Progress ==
* GCC trunk/4.9 cross-validation (CARD-647) (2/10)
- trunk build for aarch64 reported to fail because libsanitizer
requires an update. Pinged libsanitizers maintainers but got no answer
so far.
- posted testsuite patch to test if -shared is supported
- managed to find how to force target-dependent -mword-relocations
flags to compile testglue, without needing a testuite patch :-)
* Validation (3/10)
- compared cbuild2 schroot-test branch using (default) shared libs
and forcing static libs
Using static libs causes many unresolved and unsupported tests
- compared using unix.exp and arm-linux.exp: the latter causes
creates instability in the results
* Neon intrinsics tests (2/10)
- rebased on trunk, applied requested changes
- the make-check parallelization support has changed mid-September,
took some time to discover that my .exp harness was now incompatible.
* Misc (3/10)
- calls/meetings
== Next ==
* GCC trunk/4.9 cross-validation
- continue investigation of abi_check test
* Neon intrinsic tests update, trying to take float16 types into account
* cbuild2:
- compare results + validation time of stable and schroot-test branches
- look at backport-test script + logs
cbuild2 benchmarking - TCWG-360 [7/10]
* Cleaned up and upstreamed some code that works
* Fixed a couple of issues raised by LAVA people
** No longer scraping the logs
** No longer assuming stable IP addresses
lowlevellock.h comments - CARD-341 [1/10]
* Respun based on Carlos' comments
Meetings/mail/etc - [2/10]
=Plan=
cbuild2 benchmarking
* Upstream code-with-fixes
* Write a doc
* Invite people to start using this thing
** Assuming that the storage questions get resolved
* Work through list of tweaks
Get up to speed on glibc vector math thread
== Progress ==
* Investigate a number of bugs in Linaro toolchain (2/10)
- Submitted patches for cbuild build failure with eglibc and i686
- Investigated BZ #675, gdb baud rate issue. Should be fixed by
switch to cbuild
- AArch64 PIE support seems to be ok?
* Submitted a patch to add all missing relocs from AArch64 ABI 1.0 to
binutils (1/10)
* Email, meetings, etc. (1/10)
* More malloc single-thread optimizations (6/10, TCWG-436)
- Patches submitted to the list
== Issues ==
* None
== Plan ==
* More atomics work
* Tidy up and commit malloc app benchmarks
* Out Thursday and Friday for a wedding

== Progress ==
* LR register not used in leaf functions (TCWG-539) (1/10)
Reviewed Jiong's changes.
* bug #412 (2/10)
- Seems to have been fixed but since there is not specific test-case
except that it happens with spec2k gcc, need more work to be entirely sure.
* AArch64 Spec2006 int regression (1/10)
- Looked at bug databases and mailing list archive for more information
* armv3 (bug #85 and bug #410) (2/10)
- Looked at both the outstanding bug to find more information
- proposed using -mno-lra for armv3 after discussion with the team
* Misc (2/10)
- Public holiday (2/10)
- Annual Leave (2/10)
== Plan ==
* zero/sign extension elimination with widening types
== Holidays ==
* 06/10/2014 - Public holiday
