Split f_cvt type. 202329 - [Patch ARM AARCH64] Split "type" attributes: fdiv 202330 - [Patch AArch64] Fix types for some multiply instructions. 202331 - [AArch64, ARM] Rename the FCPYS type to FMOV 202332 - [AArch64, ARM] Use "multiple" for type, where more than one instruction is used for a move == Next week == Complete remaining backports for a53 support and complete builds for arm and aarch64. == Future == -- Michael Collison Linaro Toolchain Working Group michael.colli...@linaro.org ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
[ACTIVITY] Week 11
== Progress == 4 Day week (10/03/2014 - Public holiday) https://cards.linaro.org/browse/CARD-1210 (6/10) - Implemented patch to fix it and bootstrapped gcc - Regression testing pending https://support.linaro.org/tickets/727 (2/10) - Looks like a tool-chain bug - Looking into it https://bugs.launchpad.net/gcc-linaro/+bug/1270789 - Addressing review comments == Plan == - Benchmark CRC with the patches - Set-up AARCH64 qemu system - Start with VRP patches ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
[ACTIVITY] Week 11
== Issues == * None == Progress == * Validate R/M toolchain 4.8 q1 update release. * Try Cross-Native build based on Linaro crosstool-ng. * Handle conditional compare in ifcvt.c to make ccmp and csel work together. * Read document about FCMP/FCCMP and investigate on how to generate FCCMP instructions: - The tree representation of UNORDERED compare (UNLT, etc) can not fit into current framework to handle CCMP. - For LT, LE, GT and GE, the compiler will generate FCMPE instruction, which can not be the first compare of CCMP. - For NE, EQ, it is easy to handle them based on previous patches. == Plan == * Continue on ccmp performance tuning. ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
[Activity] March 10-14 (2014)
== Progress == * Went through few Linaro Connect - LCA14 slides and videos . * Restarted upstream discussions on writing machine descriptions for stack smashing. Working on submitting patches again as per Marcus suggestions. * Installed "CPU2006" in foundation model running open embedded image and tried running 403.gcc benchmark. * Tried buiding QEMU for aarch64 on ubuntu 12.04,2. I am getting segment fault on using -L . Need to debug further. * PGO runs: GCC boot strap failed when libjava building at stage3. Need to have re-look further. Issue may be missing package in opembedded image on foundation model. Misc -- Attended some Internal meetings. == Plan == * Continue machine descriptions for stack smashing work. * Work on using QEMU for running gcc test suites * Restart PGO bootstrap failure investigations ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
