Hi,
Thanks to the advice from this list I've managed to build GCC targeting
aarch64 (thanks!).
Is there some way I can now run the tests in a Foundation model? I
don't really know how this would work -- I guess using
aarch64-unknown-linux-gnu-gcc etc to build binaries, scp them onto the
model, run them and parse the output. Is this the sort of thing that
people do?
Cheers,
mwh
Short week (2 days off).
== Progress ==
* 4.8 2013.09 backports:
- Reviewed and committed several
* Wiki cleanup:
- Started to review some pages.
* LRA:
- Refactored the two posted patches in one.
== Next ==
* Backports and Releases.
* LRA
* Book hotel/plane for Connect
== Progress ==
* Libssp support for AArch64 TCWG 23:
NFS mounted from build system into the model and ran cross eglibc
tests for a fresh SVN checkout.
Had some failures. Looking at library missing issues.
* Backports
Completed backports and merge requests. Yvan helping out to commit 201411.
== Plan ==
* Post RFC patch for Libssp support for AArch64 in GCC
* Continue testing the patch for Libssp support for AArch64 in GCC
and glibc TCWG-23.
== Issues ==
* LTO/PGO work stopped now since libssp support priority is more.
Misc
-------
9-Sep-2013 AMD Bangalore holiday.
== Progress ==
* spec2k comparison between ARM and x86
- More benchmarks analysed.
- Plan to complete first iteration for spec2k-int benchmarks this week
* Addressing patch review
- Woking on vrp based zero/sign extension elimination based on feedback
- Started addressing comments for divmod optimization
== Plan ==
* Continue with spec2k comparison between ARM and x86
* Wiki Cleanup
== Progress ==
* GDB Record and Replay (TCWG-197)
Completed writing most of gdb process record Thumb32 instruction handling code.
Created test data for various types of Thumb32 instructions
Performed testing fixed some coding mistakes and bugs.
* Visa Application
Filled US visa application online for LCU13.
Prepared US visa documentation to file visa immediately after coming
back from UK.
Made travel arrangement for UK visit.
== Plan ==
* GDB Record and Replay
Integrate gdb process record thumb32 support patch with gdb source and
perform testing.
Submit patch upstream.
* Travel and Visas
Collect travel information and travel to Cambridge UK by Sunday.
* Days Off
Thursday and Friday off for a small visit to Dubai before reaching UK on Sunday.
== Progress ==
* Started setting up a GCC git mirror on git.linaro.org.
* Tweaked Cbuildv2 & Jenkins to work with GIT repositories as well
as source tarballs.
* Jenkins now "bootstraps" a cross compiler by building the native
GCC, and then using that to compile the cross GCC.
* Got aarch64-none-elf building with newlib via Cbuildv2.
* Finished binary tarball release support in Cbuildv2.
* Almost got Canadian crosses building via Cbuildv2.
* Continued work on Jenkins/Cbuildv2 integration.
* Added ccache support to Cbuildv2.
* Cbuildv2 now works on Fedora as well as Ubuntu.
== Plan ==
* Finish setting up GCC git repository with Linaro branches
fetched from svn and bzr.
* Add support for building source tarballs.
* Continuing with Jenkins/Cbuildv2 integration. (waiting for GCC
git repository to be complete)
* Get Jenkins to upload binary & source tarballs to
snapshots.linaro.org.
* Finish getting Canadian Cross builds working in Cbuildv2.
== Issues ==
* Still waiting for Odroid hardware to get shipped.
* Waiting for git-bzr-ng to be installed on git.linaro.org.
* Git-svn is incredibly slow on initial fetch. (fetching the
linaro/gcc-4_8-branch has been running over 24 hours)
== Progress ==
* Worked on getting glibc benchtests into shape for string functions
* More wiki cleanup (done?)
* Backports and release of eglibc 2.18 2013.09
* Booked Cambridge trip for Sept 17th
== Issues ==
* None
== Plan ==
* More improvements to glibc benchtests for strings/malloc if possible
* Get back to malloc and stack guard work

== Progress ==
* Backports for 2013.09:
- committed several
- reviewed
- submitted a few new ones
* Wiki pages cleanup
* GCC trunk cross-validation:
- need to work around results instabilities caused by incomplete
threads support in QEMU.
== Next ==
* Release 2013.09 next week after completing the latest backports.
* Resume investigation on perfomance regression with peeling disabled.
* GCC trunk validation: work on reporting
* Book hotel/plane for Connect
== Progress ==
* Cross-compilation
- Cleaning up v7A cores and features in Clang
- Writing document on how to cross-build using Clang/LLVM
- Creating bugs to deal with the issues found
- Adding LZMA library dep to cross-build in LLVM
- https://cards.linaro.org/browse/TCWG-200
* Divmod 64
- Long discussions about libcalls using registers with ARM
- Trying to revive my old patch due to future improvements from ARM
- It should also help future improvements on value_in_regs attributes, as
well as other library calls in registers or with multiple return values
- https://cards.linaro.org/browse/TCWG-199
* Maintenance
- Patch reviews, discussions, as usual
- Investigating breaking test-suite bot
- Added two pandas to the lab for general use
== Plan ==
* See that all patches created this week get through
* Have a look at automating Phoronix (via Jenkins)
* Find SLP-vectorizer regressions on ARM and fix them
Progress:
* rebased and fixed last issues in aarch64 prep patchset, sent it
out with a note that I'm going to put it in a pullreq to be
applied unless any further comments come up in review
* reviewed Christoffer's GIC save/restore patchset
* reviewed and cleaned up toolchain's QEMU wiki pages
