== Progress == * Validation - armvl8 differences between master and stable branches understood (master defaulted to Thumb) - updated ABE stable branch for validation - ABE now uses linaro-local/stable DejaGnu branch - updated ABE legacy version to use this DJ branch too, and updated the Foundation Model path - updated Jenkins jobs accordingly * Backports - created a few backports for our gcc-5 branch, to prepare handover - slight documentation update * GCC - enhancements to validation harnesses to better handle infrastructure problems - using monitoring and regressions reports * Cortex-strings - updated a few aarch64 mem* routines from newlib versions * Support - finally reproduced the Windows-hosted toolchain bugs by rebuilding in a properly updated Jessie chroot. - building the next release in Trusty container should fix these problems * Misc (confi-calls, meetings, emails, ) == Next == * Validation: cleanup & reviews * GCC - trunk monitoring, report regressions if needed - more intrinsics tests ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org https://lists.linaro.org/mailman/listinfo/linaro-toolchain

== Progress == * Rework LLVM helper scripts [TCWG-571] [4/10] - Code review + minor improvements to the scripts - Started a discussion about the interfaces of some of the scripts (llvm-projs, llvm-sync) * Inline assembly constraints support for ARM [TCWG-560] [3/10] - More investigations for PR24071 - Discovered that the assert is only triggered for aarch64-linux-gnueabi, whereas arm-linux-gnueabi behaves as expected (prints the error but doesn't assert afterwards). This has proven useful for figuring out the intended behavior of the code. * Move buildbots to CMake 3.4.3 [TCWG-573] [1/10] - Helped move some of the bots (llvm-a15-*) to CMake 3.4.3 * Misc [2/10] - Buildbot monitoring - Meetings == Plan == * Inline assembly constraints support for ARM [TCWG-560] - Come up with a fix for PR24071 * Rework LLVM helper scripts [TCWG-571] - Start a review for the new interface to llvm-projs/llvm-sync, so we can have some concrete support for further discussion - Investigate git worktree and how it could be factored into our scripts (llvm-projs, llvm-build) * Move buildbots to CMake 3.4.3 [TCWG-573] - Help with the llvm-chrome-* bots if necessary * OOO on Monday ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org https://lists.linaro.org/mailman/listinfo/linaro-toolchain

# Progress # * TCWG-518, range stepping on arm-linux. Rebase my patches, and choose a different approach which is better. However, GDBserver crashes in some cases, and I am investigating the crash. [5/10] * TCWG-547, make some progress on the upstream discussion. We agree to do it in a cleaner way but some GDB internal interface needs some changes. [2/10] * Read some articles about exception handling, this one is quite useful, https://gcc.gnu.org/ml/gcc/2002-07/msg00391.html [1/10] * Meeting, upstream patch review. [2/10] # Plan # * TCWG-518, TCWG-547 -- Yao ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org https://lists.linaro.org/mailman/listinfo/linaro-toolchain

# Progress # * TCWG-466, ADRL pseudo instruction support in integrated assembler. I couldn't find a way of putting ADRL into the assembler in a maintainable way. Managed to work out a pretty close approximation of ADRL in a macro so I added it to upstream PR. Put the results of the my investigations into TCWG-466. Agreed with Renato's initial diagnosis of won't fix. * TCWG-468, Transform LDR rn, =expr pseudo instruction into MOV. I'm more hopeful with this one. I've got a prototype that delays the emission of the constant pool entry to a point where the transformation can occur. * Try out the build and push scripts. Had a frustrating day of chasing down missing dependencies from my Ubuntu 12.04 machine while building lldb. Should be resolved now. # Plan # * UK national holiday on Monday. * Continue with TCWG-468. I've got a tablegen prototype that treats LDR rd,= as a real pseudo instruction. Need to finish Thumb and Thumb2. Next step after that is to do the transformation to MOV. * Will spend any other time investigating LLD ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org https://lists.linaro.org/mailman/listinfo/linaro-toolchain
