[ACTIVITY] Week 5
* 2 days week (university & child care). == Issues == * none == Progress == * LRA on AArch32: o TCWG-343 : Make LRA the default for the ARM backend (0/10) - No progress this week o TCWG-345 : Analyse performance of LRA for ARM. (1/10) - Configured and ran benchmarks on Cortex-a15. * Looked at Linaro 4.8 release performance on Cortex-a15. (2/10) * Misc. (1/10) o Booked Hotel and flight for connect == Next == * Back on LRA and lib GMP ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain

The kernel has lots of these errors, but disables the warning explicitly: # disable pointer signed / unsigned warnings in gcc 4.0 KBUILD_CFLAGS += $(call cc-disable-warning, pointer-sign) -- Will Newton Toolchain Working Group, Linaro ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
[ACTIVITY] 27-31 Januery 2014
* Libsanitizer for AArch64: (4/10) - seems to be mostly working, but trouble with validation both using the Foundation Model and qemu-aarch64. - Some tests seems to loop forever while unwinding under qemu, but run fine under the Foundation model - Conversely the Foundation Model shows some random errors, and the corresponding tests pass under qemu - Some random timeouts with the Foundation Model, despite using ssh multiplexing - Added a small patch to qemu to hande missing mmap flag. Need to send upstream. - asked Rob to run GCC testsuite with my patch on AArch64 but it's too unstable these days * Cross-validation (2/10) - script now able to validate a GCC patch and compare results with unmodified GCC trunk - added arm-none-eabi target - using qemu-aarch64 for aarch64-none-linux-gnueabi but the validations now time out. Need investigation, but I might have to revert to no execution for this target. - identified a problem with the recent armv7-ve patch * Benchmarks: (1/10) - collecting data for 4.8 tables * Peeling: (1/10) - backported new vectorizer cost model to check it if's OK to include it in our next release * Misc (2/10): conf-calls, meetings, docs (howtos for TCWG) == Next == * libsanitizer on AArch64 * fix cross-validation on aarch64-none-linux-gnu * benchmarks: complete table * backports: chek new vectorizer cost model, monthly branch merge, review Michael's backports of Crypto intrinsics ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
[ACTIVITY] 27 - 31 January 2014
== Progress == * Fixed remaining issues in rework of hwbreakpoint and watchpoint implementation for arm native targets. Tested and submitted patch. [TCWG-177] [8/10] * Installation and Setting up of new desktop machine. [2/10] == Plan == * Run testsuites to see current status of arm gdb. * Follow up on submitted patches. * Public holiday on Wednesday 5th February. ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
