== Next week ==
On vacation June 16th - June 20th
== Future ==
No Plans
= Progress ==
* Went to UK VISA office and submitted application and bio metrics (2/10)
* Tried Installing chrubuntu on chromebook. But failed and later found that
SD card issue. Given SD card back in office for replacement. Installed
crouton and other packages for building gcc and testing gcc testsuites
(1/10)
* Reload spill failure (bug fix) on armhf target (3/10)
Tested conservative patch that prevent ior_scc_scc patterns for thumb2
target using chrome book.
Thumb2 compare condition test cases fails. Found that these test cases
using constants for operands 2 and 5. Change conservative patch to allow
constant operands for thumb2 target in ior_scc_scc patterns. Testing is in
progress.
* LTO experiments (2/10)
Drilling down ICE with LTO on GCC 4.9 branch.
* Misc (1/10)
- 1-1 meetings (Ryan, Christophe) (0.5/10)
- AMD internal support work and meetings (0.5/10)
* Installed some packages and tested christophe libsantizer patch on
hardware (1/10)
== Plan ==
* Continue bug fixing.
* LTO bootstrap failure
== Progress ==
* Public holiday (2/10)
* Benchmarking and regression testing (TCWG-468) (8/10)
- Ran release benchmarking in chrome-book
- Set-up package build environment and ran ubutest
- spec2k benchmarking of patches that was included in 2014.06 release
on aarch64
== Plan ==
* Benchmarking.
* Upstream zero/sign extension elimination activities.
== Issues ==
* None.
== Progress ==
* Work out 4 patches to enhance loop2-invariant heuristics and send
out for community review (TCWG-469, 3/10).
* Test the rebased ccmp patches (TCWG-488, 2/10).
* Investigate how to optimize large constant. Patch is in testing
(TCWG-486, 5/10). Basic idea is:
- Do not split large constant when expanding.
- Improve cprop pass to check the rtx_cost when propagating constants.
== Plans ==
* Ping pending patches.
* Send out ccmp patches for review.
* Send out patches to optimize constant.
== Progress ==
* Kernel (CARD-1246 1/10)
- Helping LLVMLinux to test in LAVA
* Background (9/10)
- Code review, meetings, discussions, etc.
- Setting up Chromebooks again (up, crouton)
- Setting up APM boards (up)
- Setting up D01 boards (bricked 2)
== Plan ==
* work with guodong, fabo, tyler, to revive the D01s
* put crouton on llvm-chrome-test to be ready for release 3.5
* have a look at compiler-rt autoconf build
* keep helping LLVMLinux with LAVA
Monday off. (2/10)
== Progress ==
* GCC trunk cross-validation (CARD-647) (3/10)
- improved scripts to avoid consuming to much memory
- improved kill signals handling when generating reports
- back to normal
- started looking at adding libstdc++ in the reports
- started looking at adding aarch32/armv8 configuration
- email-driven robot looks operational. Started testing with Kugan
* GCC 4.9 branch cross-validation (CARD-647)
- it's now running
* Neon intrinsic tests (CARD-???) (2/10)
- discussion started: scan-assembler directives may be difficult to maintain
- original testsuite maintenance: preparing aarch64 support
* AArch64 libsanitizer support (TCWG-58)
- Venkat tested my patch on HW, need to study the results and
compare with qemu
* Misc (meetings, conf-calls, ...) (3/10)
- 4.7-2014.06 branch merge prepared, validation started
== Next ==
* GCC cross-validation
- check patch to add libstdc++ in the reports
- define configuration for aarch32/armv8
- continue testing of the email robot
* Neon intrinsics tests:
- handle feedback
- original testsuite: continue aarch64 support, investigate output
formatting problems
* AArch64 libsanitizer support:
- analyze results
- use cbuild2 + tcwgbuild configs to run the tests myself on HW
* Backports reviews
