GCC bootstrap build error with openembedded/v8 model

by Venkataramanan Kumar

Hi all, I am facing build error, when I try to bootstrap GCC trunk for native aarch64-unknown-linux-gnu configuration in openemedded/V8 model. Linker error occurs while building stage 1 GCC. (Snip) /usr/lib/gcc/aarch64-oe-linux/4.7.3/../../../../aarch64-oe-linux/bin/ld: gcov: hidden symbol `__deregister_frame_info' in /usr/lib/gcc/aarch64-oe-linux/4.7.3/../../../aarch64-oe-linux/4.7.3/libgcc_eh.a(unwind-dw2-fde-dip.o) is referenced by DSO /usr/lib/gcc/aarch64-oe-linux/4.7.3/../../../../aarch64-oe-linux/bin/ld: final link failed: Bad value collect2: error: ld returned 1 exit status (Snip) The steps to reproduce the issue is attached. Need some help to solve this. regards, Venkat.

== Progress == * Neon intrisincs: compiled my testsuite with GCC/trunk and filed bugzilla 57431 for ICE. * Merges for linaro-4.8-2013.06: started actual merges - fixed a cbuild reporting problem - faced calxeda and e2c problems, fixed by Matt. * Jira: a few updates * Libsanitizer: patched upstream, to be backported in GCC/trunk, then in gcc-linaro-4.8. == Next == * Merges for linaro-4.8-2013.06: complete them. * Disable-peeling: resume * Look at Kugan question about trunk regression * Libsanitizer/aarch64: resume * PGO/LTO/python bug: resume * Neon intrinsics/vzup/vero: resume

[ACTIVITY] 27 - 31 May 2013

by Omair Javaid

== Progress == * Investigated attach to process and threads failures (TCWG-95<http://cards.linaro.org/browse/TCWG-95>). Almost all problems were fixed with any patch by making an os configuration change on chromebook. * Ran GDB test suites after OS configuration change on chromebook and updated test results. * Investigated inline-break.exp test suite failures on arm. GDB seems to be missing one inlined instance on two different functions. Obtained debug info and dumps of obj file without any luck to find the possible cause and fix. * Started work on integration of different testing scripts. Initially added commandline options in bash script to test let user choose target/host, native-none/native-gdbserver/remote, and testsuite/testcase configurations. == Plan == * Figure out a reason/solution for inline-break.exp failures on arm. * Investigate and Fix more ARM bugs shown in gdb 7.6 testsuite results. * Chromebook os update on a faster sd card. * Side activity work on automation of testing gdb in different configurations and uploading comparison result.

== Issues == * None. == Progress == * LRA on ARM and AArch64: - Tried to workaround the issue with new insns (reload_outdi,...). - But it doesn't seem to be handle by LRA. - Debug still ongoing. * Internal meetings == Plan == * Releases merge reviews * LRA

== Progress == Very short week (monday and wednesday off). * AARCH64 testing Got boot strap failure with GCC 4.9 trunk on open embedded image with glibc changes. Retired with latest openembedded image on V8 model Noted down the steps to reproduce boot strap failure in the model for broadcasting. * libssp support for Aarch64 Read documentation to understand and evaluate the work. == Plan == * Continue bootstrap testing and push patches to GCC * Implement Libssp GCC back end hooks. * Linaro connect travel prep, book tickets hotel and apply visa.

by Kugan

== Progress == * VRP based zero/sign extension - Tested and posted the latest patch * Better end of loop counter optimisation - Tree level optimization are optimized in mainline - Christophe noted a slight change in asm generated from earlier version - tracked down the patch causing this and communicated this. * Generate a single call to divmod - Looked at expand_divmod to understand how __aeabi_idiv and __aeabi_idivmod are generated. == Plan == * Better end of loop counter optimisation - Change the pattern to remove this additional instruction if necessary. * Generate a single call to divmod - Come up with a solution

== Issues == * None == Progress == * Shrink wrapping improvement (TCWG-133) - Call copyprop to optimized the parameter register move instructions. - Test is ongoing. * Update aarch64-none-elf toolchain newlib version to 2.0~20130530 (lp:1185711). == Plan == * Collect performance data for TCWG-133. * Continue on conditional compare. Best Regards! -Zhenqiang

[ACTIVITY] for week 22

by Rob Savoye

== Progress == * Monday holiday here too, so went mountain climbing * Finally fixed Lava token for cbuild * Dug into EC2 issues, still confused * Cloned infrastructure files from gcc.gnu.org, which turned out to be out of date, so updated them to the current releases. That then required fixing a few minor configure bugs in libppl. Files in ~/cbuild/var/snapshots/infrastructure. Infrastructure libs are statically linked so they're consistent across platforms. * Worked on cbuildv2, it now downloads a tarball or does a bzr|git|svn checkout, configures, compiles, and installs them in a sysroot as other packages depend on them. Also added a function to download, build, and install all the toolchain infrastructure libraries in a sysroot for binutils & GCC to use at build time https://git.linaro.org/gitweb?p=people/rsavoye/cbuild2;a=summary * Automated import of all historical test results till running. Currently the DB has 137,687,996 test results, 1909 separate test runs of GCC, and covering 544 versions. == Plan == * Add remote SSH support to DejaGnu for remote testing on Chromebook. (carried over from this week) * Figure out the EC2 mess and document it better * Clone gcc_release.sh script but enhance so a similar process can be applied to releasing Eglibc, Newlib, and the Binutils. * Start gearing up for the releases * Finish cross build and testing support in Cbuildv2, which would basically eliminate the need for crosstool-ng.

[ACTIVITY] Week 22

by Will Newton

== Progress == * 4 day week due to bank holiday. * Merged binutils arm ifunc changes onto stable branch. * Worked on getting some git mirrors setup for various toolchain deliverables. * A certain amount of planning and JIRA card work in preparation for the next iteration. * Fixed aarch64_be-* and aarch64-elf testsuite issues with AArch64 ifunc patch. * Investigated glibc malloc and alternatives. == Issues == * None. == Plan == * Submit new AArch64 ifunc patch after testing complete. * Finish getting git mirrors setup. * Look at some gdb testsuite failures. -- Will Newton Toolchain Working Group, Linaro

[ACTIVITY] report week 22

by Peter Maydell

[very short week; two days] Progress: * misc ** handover from John Rigby: got a QEMU+KVM+AArch64 setup running with his work-in-progress patchset ** tracked down weird behaviour when ^C'ing qemu on aarch64 to a bug in glibc's getcontext() implementation (it doesn't clear the PSTATE field and ends up passing a garbage pstate to the rt_sigreturn syscall) Plans: * VIRT-55: talk to Andre about testing; investigate testing migration using LAVA * set up a new qemu-linaro tree/branch as our CI/LAVA input [to keep it separate from our "we release this" tree] * restart work on upstreaming omap3 patches as part of my generic qemu maintenance work (will reduce our maintenance burden in the long term) -- PMM
