[ACTIVITY] 3 - 7 December 2018
[LLVM-499] LLD support for linking the linux kernel - [LLVM-504] Support for linker script symbol assignment to an alias. -- Diagnosed problem and made reproducer on PR. -- Reviewed the upstream patch. - [LLVM-503] Support for discarding .dynamic, .dynstr and .dynsym -- Reviewed upstream patch and proposed testcase that is representative of the kernel use case. Some revisiting of scripts and advice on how to cross compile clang libraries. Looks like I have some updates to do to the documentation for some configurations I haven't tried before. - 2 days at ARM internal Codegen conference. Really good event, standard of work was very high, left enthused.

== Progress == * FDPIC - GCC: no feedback yet on v4 patches - GDB: did not decide yet how/if to commonalize with frv code. Asked for advise on the gdb list. * GCC upstream validation: - reported a few regressions, helped testing some patches - dealing with some random results, still - trying qemu-3.1.0-rc3, memory consumption problems with aarch64-linux. LSF reports (cgroup-based) do not seem consistent with time --verbose. * GCC: - rebased ubsan / bare-metal patches. Trying to build an LLVM toolchain to see how to properly apply my patches * misc (conf-calls, meetings, emails, ) - reviewing/submitted infra script patches - ran Spec2006 on aarch32 using gcc-8.2 sysroot, results match the previous ones, so the improvements are only imputable to the compiler. - dealing with nasty ST-internal infrastructure problems - trying to look at noinit/persistent attributes provided by other toolchains, need a windows machine :( == Next == FDPIC: - GCC: handle feedback on v4 patches - GDB: update patches - uclibc-ng: look at how to test fdpic mode with openadk Benchmarks: - collect results Validation: - isolate if/why qemu-3.1.0-rc3 consumes more memory than 2.11 for aarch64-linux target ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org https://lists.linaro.org/mailman/listinfo/linaro-toolchain

== Progress == # [LLVM-492] [Thumb GlobalISel] Lower parameters for Thumb functions - Committed upstream # [LLVM-500] [Thumb GlobalISel] Support G_ADD, G_SUB, G_MUL - Started working on this but it became apparent that the existing tests would be easier to reuse if we had support for G_LOAD first # [LLVM-506] [Thumb GlobalISel] Support G_LOAD and G_STORE - Investigated whether we could get TableGen to select G_LOADs and G_STOREs by porting ComplexPattern - Unfortunately that is not enough, and even AArch64 has hand-written code for it in the instruction selector - Will handle it the ugly way next week == Plan == # LLVM-506, LLVM-500 ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org https://lists.linaro.org/mailman/listinfo/linaro-toolchain
