[ACTIVITY] report week 13

by Peter Maydell

Progress: * qemu maintenance ** https://ci.linaro.org/jenkins/job/qemu-ltp/ now shows graphs of LTP test results for linux-user mode ** rebased qemu-linaro and got it working again (omap3 display code needed rework after upstream changes) ** investigated why Christoffer Dall's kernels weren't booting: turns out to be that vexpress now requires CONFIG_REGULATOR but doesn't force it to be set or set it in the vexpress_defconfig ** rebased/resent/pinged various in-flight patches * VIRT-4 [Guest migration support for KVM] ** VIRT-49: implement cp15 sync with kernel *** located my work on this from last year, refreshed my memory on how far I'd got and what I was planning to do -- PMM

== Progress == * Re-installed the panda buildbot, using USB drive as bot dir * Reviewing lots of ARM patches (more than usual) * Trying Arndale again, some errors, some passes, cooler might be responsible - Got one internal error, one build error and one pass with Ubuntu kernel + patch - Trying Suse image: - It has a broken serial driver (makes things much harder) - sshd does not start by default (in conjunction with serial bug, it's a killer) - Now running on a precarious mode, hopefully enough for our needs * sqlite3 error due to VMUL.f64 while on x86_64 "long double" is f128 - sqlite3 is the best example on what NEVER to do with floating point values >:| - Sent patch, working around TILE-Gx issues == Issues == * Still a bit ill, productivity reduced * Not having a wired network on my desk wastes a LOT of my time == Plan == * Push the sqlite3 patch though * Continue fixing the 4 remaining broken tests * Continue with Arndale investigation with Christophe and Zhenqiang

GCC bootstrap on Arndale

by Renato Golin

Hi folks, I'm trying again the bootstrap of GCC on Arndale and it goes pretty well until it has to install libgcc that it just compiled. When I build first time, I get an error while installing libgcc: make[4]: Entering directory `/home/linaro/devel/gcc/build/objs/armv7l-unknown-linux-gnueabihf/libgcc' /bin/bash /home/linaro/devel/gcc/src/libgcc/../mkinstalldirs ../.././gcc (...) /bin/bash /home/linaro/devel/gcc/src/libgcc/../mkinstalldirs ../.././gcc; /usr/bin/install -c -m 644 ./libgcc_s.so.1 ../.././gcc/libgcc_s.so.1; rm -f ../.././gcc/libgcc_s.so; /usr/bin/install -c -m 644 ./libgcc_s.so ../.././gcc/libgcc_s.so Live child 0x01dec548 (install-shared) PID 4405 Reaping losing child 0x01dec548 PID 4405 make[4]: *** [install-shared] Error 1 Though, if I run that command by hand, it works... I then re-ran make and the first point there is an error is on gmp: This program built for arm-unknown-linux-gnueabihf Reading makefiles... Reading makefile `Makefile'...

Live child 0x00ae17f8 (all-stage1-libiberty) PID 4755 I can't notice anything wrong on gmp (all objects are there), other than a number of symlinks to a missing directory: gmp-mparam.h -> /home/linaro/devel/gcc/src/gmp/mpn/generic/gmp-mparam.h the directory "generic" doesn't exist, and lots of files in "mpn" also point there. Could be a red herring, though. Any ideas? cheers, --renato PS: this doesn't look like an Arndale specific bug, so we might still be able to use them for GCC bootstrapping...

[ACTIVITY] Week 12

by Zhenqiang Chen

Summary: * Send out shrink-wrap related patches for review. * Investigate how to add a new tree code. Details: 1. Fix lp:1157050 and lp:1107659 for Linaro toolchain binaries. 2. Test shrink-wrap dwarf/unwind info and send out the patches for review. 3. Make progress on conditional compare support. With some hard-codes in gcc, it can gimplify a small case to conditional compare on tree and no assert until expand. Plan: * Investigate how to expand conditional compare GIMPLE to RTL and emit asm. Planned leaves: * March 31. * April 4-8. Best Regards! -Zhenqiang

Testing binutils natively

by Will Newton

Hi all, I'd like to run the binutils testsuite in a native configuration regularly to find any regressions. Do we have any infrastructure for doing this? It looks like LAVA would be useful but it looks complex and I am not sure if we use that already for running toolchain tests (I think there was a Connect session about that?). Thanks, -- Will Newton Toolchain Working Group, Linaro

== Progress == * Disable-peeling: - benchmarking locally on snowball - failed to build reference branch on cbuild, for an unknown reason * Turnoff 64bits ops in Neon: - committed upstream in 4.9 (now stage 1) - benches of backport into Linaro-4.7 OK: no significant diff, except +12.6% on spec2k's crafty) - Filed merge request. * Vectorizer cost model: - benches of backport inot Linaro-4.7 OK (no significant diff, as expected). - Filed merge request. * Revert-coalesce: - benches ran in cbuild, but no *-diff.txt file generated. * Libsanitizer: - testsuite results OK. All unsupported tests are normal. * Neon intrinsics codegen: - got internal feedback * GDB reverse debug: - filed 2 bug reports after internal requests. * Misc: - filed several bug reports against cbuild to track the problems I observed. == Next == * Disable-peeling: - analyze bench results - understand/'fix what's wrong with cbuild * Turnoff 64bits ops in Neon: - backport to Linaro-4.8 * Revert-coalesce: - manually compute bench differences if unable to have cbuild do it. * Libsanitizer: - propose patch upstream.

== Progress == Knocked out more GDB remote configuration failures that were failing due to timeouts. Had 1:1 with Matt for direction on GDB improvement plan. Looked around for Ireland visa process and filled out visa application. == Plan == Complete review of remote timeout based test case failures. Start work on the GDB improvement blueprint in JIRA from this week. Get remaining documentation for Ireland visa and complete application.
