* Core mark benchmark and report for PGO and PGO + LTO (TCWG-544) (6/10)
Going by CPU cycles adding LTO gains in x86 and degrades in Aarch64 .
Looked at hot functions and examining assembly the code generation seems to
be same. X86_64 does alignment of code. Also branch misses decreased in
X86_64 compared to Aarch64 with -flto + -O3.
Also profiled for instruction counts on Aarch64 with linaro compiler. These
profiles say that we are executing less instructions with LTO and PGO for
Aarch64.
* PR 63173- Reproduced the issue and changed the test case to work with
trunk. Now Looks like someone else has a patch for it. (1/10). so will
work on other bugs.
* Misc [3/10]
Internal work, emails, AMD meetings and 1-1 with inline manger.
1-1 with Maxim, christophe and 1-1 with ryan
== Plan ==
* Coremark benchmark and profiling.
Investigate trunk degradation for O3+ PGO + LTO and report.
== leaves ==
Diwali holiday (22-24)
== Issues ==
* Still no network at home and will not be fixed before at least one week :(
== Progress ==
* GCC 4.9 2014.10 (8/10)
- Merged FSF 4.9 branch
- Released Linaro 4.9 2014.10
* Misc: (2/10)
- Various meetings.
== Plan ==
* Analyse some failures that occur only in --enable-release.
== Progress ==
Catch up with work after return from Eid ul Adha and Annual Holidays [7/10]
* Hong Kong visa application
* UPS repairs and office cleanup
* Catching up with work, gdb roadmap and open/running cards.
* Emails/Patch scrolling/Meetings etc
* Sick day off on Monday
GDB Tracepoints/Fast Tracepoints support on arm [TCWG-480] [3/10]
* Getting re-synced with code where I left.
== Plan ==
Further progress on GDB Tracepoints/Fast Tracepoints support on arm [TCWG-480]
Investigate possibility of AArch64 trace-point work without
availability of hardware.
Check for GDB status on ARM and AArch64 vs x86.
== Progress ==
* Zero/sign extension elimination with widening types (TCWG-546 - 9/10)
- Fixed ICEs and now can build the cross compiler and do the regression
testing with qemu
- some test-cases are failing due to condition that rely on overflow;
this need fixing.
- Bootstrapping on AArch64 still fails (but much later than previously).
- Verified CRC is optimized
* Improve block memory operations by GCC (TCWG-142 - 1/10)
- Looked at the changes since the card was drafted
== Plan ==
* Continue with Zero/sign extension pass.
== Progress ==
* GCC trunk/4.9 validation (CARD-647) (3/10)
- committed testsuite patch to test if -shared is supported
- forcing -mword-relocations flags when compiling testglue works on
my Ubuntu machines, but does not in the Compute Farm RHEL5 servers.
- investigating why, all the more as it made me incorrectly report
failures in the 4.9 branch
* Validation (2/10)
- compared cbuild2 schroot-test branch and master
the results of this manual run does not seem to match Jenkins results
* Neon intrinsics tests (1/10)
- fixed .exp harness to support parallelization
- looking at how to pre-support fp16, will probably skip it for now,
and add dedicated tests later
* AArch64 sanitizer (1/10)
- GCC trunk seems to need to cherry pick a sanitizer patch when
building using recent kernel headers
- tried to use Jenkins to build trunk and trunk+cherry-pick, but the
results are not consistent
needs more investigation
* Misc (3/10)
- calls, meetings, irc
== Next ==
* GCC trunk/4.9 cross-validation
- fix -mword-relocations support
- investigate abi_check test
* AArch64 sanitizer
* Neon intrisics tests update
* cbuild2:
- analyze previous results (mostly check the logs....)
- look at backport-test script + logs
Short next week: off Wednesday/Thursday
== Progress ==
* Respin of malloc single-thread optimizations (4/10, TCWG-436)
- Create a generic header, include AArch64 in series
* Further work on malloc app benchmark framework (4/10, TCWG-441)
- Cleaned up, improved reliability, added comments
- Committed to cortex-malloc.git
* Email, meetings, etc. (1/10)
* Upstream work (1/10, CARD-341)
- glibc patch review and pings
- Look into some bug reports and testsuite failures
== Issues ==
* Electricians and gas engineers turning off power/heating at various points
== Plan ==
* Hopefully get some resolution of single thread atomic stuff for glibc
