Holiday Thursday afternoon and Friday [3/10]
Benchmark automation - TCWG-360 [4/10]
* CPU2006 patches cleaned up, submitted
* A few other small fixes
Misc [3/10]
* ~1/10 getting a Juno running
=Plan=
Holiday next week, then:
Pick a direction on streaming vs listeners, write down the reasoning
Follow up (close out?) results storage and restricted targets
Write more tests, refactoring where appropriate
Investigate running benchmarks through ci.linaro.org
If time, and it looks sane, wrap a LAVA job around benchmark scripts
== Progress ==
LLDB development
-- Submitted and committed AArch64 hardware watchpoint/breakpoint
support [2/10] [TCWG-771]
-- Submitted Arm hardware watchpoint/breakpoint support [1/10] [TCWG-770]
-- Debugged arm watchpoints on Nexus 7 Android device. [2/10] [TCWG-651]
Miscellaneous [5/10]
-- Submitted AArch64 gdb record-replay patches
-- Travel to Islamabad for interview at French Embassy
-- Meetings, emails, discussions etc.
== Plan ==
LLDB development
-- Fix issues with hardware watchpoints and try to run tests on Nexus 7
-- Update and resubmit Arm hardware watchpoint patch.
== This week ==
* TCWG-619 (2/10)
- Disabling seccomp-bpf, works with LTO build for chromium for
multiple partitions (-flto-partitions={balanced, 1to1})
- disabling fPIC does not prevent the error - "branch out of range"
for single or no partition (--param lto-partitions=1 / -flto-partitions=none )
- The docs say there is option to disable PLT (-fno-plt),
https://gcc.gnu.org/onlinedocs/gcc/Code-Gen-Options.html#Code-Gen-Options
but using it results in unrecognized command line option.
* PR49551 (2/10)
- Found out why r221297 prevents the ICE:
merge_decl() calls make_decl_rtl() upon condtion DECL_RTL_SET_P (olddecl),
which causes the ICE. Before r221297, in merge_decls() DECL_RTL_SET_P
(olddecl) was true which resulted in call to make_decl_rtl() causing
ICE. After r221297, DECL_RTL_SET_P (olddecl) is 0, which doesn't
result in call to make_decl_rtl() so no ICE is produced. However,
DECL_COMMON is still incorrectly set in merge_decls() because it
copies newdecl into olddecl.
- Will post upstream for review after final testing on x86 and ARM.
* Misc (6/10)
- Exams
Short week (2 days off)
== Progress ==
o Upstream GCC (3/6)
* Flags for Cortex-a53 erratum #84341 workaround:
- Backported into FSF 4.9 and 5 branches
* Some cleanup to avoid format-security warnings
* TCWG-786 (LRA and PIC): Look for potential improvements
- nothing found so far.
o Linaro GCC release (2/6)
* Reviewed FSF branch merge into 4.8 branch
* Look at differences between our actual source tarball, and
the ones that can be created by ABE.
o Misc (1/6)
* Various meetings
== Plan ==
- Continue ongoing tasks
Benchmark automation - TCWG-360 [7/10]
* Convinced benchmark scripts to run entirely within LAVA
* Did a couple of benchmark runs for Kugan
* Cleaned up my CPU2000 patches and committed to central repository
Misc [3/10]
=Plan=
Clean up, commit CPU2006 patches
Pick a direction on streaming vs listeners, write down the reasoning
Follow up (close out?) results storage and restricted targets
Write more tests, refactoring where appropriate
If time, and it looks sane, wrap a LAVA job around benchmark scripts
== Progress ==
* Upstream GCC (5/10)
- committed delaying constant splitting in arm after full testing
(TCWG-486)
- Spec benchmarking is still an issue (TCWG-779)
- Bernie agreed to kindly help benchmark it
- taking time due to long lava queue
- Started working on widening pass based on review comments (TCWG-555)
- Wilco from ARM provided some test-cases and looking into it as well
* GCC bootstrap/build issues (4/10)
- Looked at bare-metal
- aarch-elf-none issue
- gcc bootstrap issue with ARM
- middle-end error
- Thanks to all, all now fixed in mainline.
* Misc (1/10)
- gcc-patches, gcc-bugs list
- Meetings
== Plan ==
- Continue with gcc stage1 activities
- Look at register allocation
# Progress #
* TCWG-517, GDB AAarch64 record/replay. Ongoing. [3/10]
Takes over from Omair, complete test cases and update patches.
Rewrite the test case using gcc inline assembly.
Happen to see that AAarch64 doesn't have CPSR register but
GDB thinks it has. This should be fixed separately later.
* Think about GDB version in next linaro toolchain release. [3/10]
The next linaro release is on July/Aug and the next GDB FSF release
7.10 will be on mid of June. I prefer to picking up 7.10, but need
Ryan or Maxim to make a decision.
* Exchange emails with Peter to push GDB kernel awareness work forward,
and think about how do that in next step. [1/10]
* Misc [3/10]
** Print and photocopy documents needed for France visa application.
# Plan #
* Go to France Embassy in London on Monday.
* GDB AAarch64 record/replay test and upstream submission.

Hi,
I tried on abe 'stable' branch and with below configuration build was
successful.
../abe/configure --with-fileserver=148.251.136.42 --with-remote-snapshots=
http://148.251.136.42/snapshots-ref
../abe/abe.sh --target aarch64-linux-gnu --build all
(Additionally I had to increase the wget_timeout=100)
But on master branch, with below commands (as suggested in above mail)
following error were observed.
../abe/configure --with-fileserver=148.251.136.42
--with-remote-snapshots=/snapshots-ref
../abe/abe.sh --target aarch64-linux-gnu --build all
ERROR (#144): fetch_http (md5sums doesn't exist and you disabled updating.)
Looks like following commit is causing problem on the abe master branch.
On removing it, build successfully downloaded the packages from
148.251.136.42.
commit 5a5ab3582851d52d903846d34c79850f5d7ebda5
don't try to fetch anything is updates are disabled.
Thanks
Virendra
