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.

== Progress == - Worked on VRP based zero/sign extension elimination at tree level - Some regression test cases are failing; investigating them == Plan == - Analyse the reason for test case failure and fix them - Extend the code to handle all the possible cases (currently implemented for subset to get the framework working)
