== Progress == * IPA VRP and Early VRP - Posted patch series and revised based on review - Few patches are accepted; others are waiting for re-review * Tree VRP - Converted to use allocpool * Committed upstream tree-reassoc patch for missed optimization due to factoring out CONVERT_EXPR in phiopt. == Plan == - Follow upon remaining upstream patches - IPA VRP ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org https://lists.linaro.org/mailman/listinfo/linaro-toolchain

# Progress # * TCWG-518, ARM range stepping patches. [2/10] The last one is approved, and all patches are committed! Need to enable range stepping and collect the performance data. Range stepping should speed up remote debugging. * TCWG-655, Workaround ARM linux kernel ptrace bug on setting VFP registers. No response from upstreams. * TCWG-333, Thumb mode function pointer assignment in GDB. [3/10] Try a different approach, still causes regressions. I'll ask upstream how to do it. * TCWG-547, Change software_single_step interface to return a vector of address. [4/10]. Patches are done, but need to figure out how to hook them together. * TCWG-685, GDB 7.12 release. [1/10] The release will be in Sep, and hopefully it can be done before the Linaro Connect. Discuss on how/when to pick up 7.12 in Linaro toolchain release. I am inclined to upgrade GDB in linaro release from 7.11 to 7.12 in fall or winter. # Plan # * Off on Tue and Wed. * GDB 7.12 release testing for ARM and AArch64. * US visa application. -- Yao ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org https://lists.linaro.org/mailman/listinfo/linaro-toolchain

== Progress == TCWG-680 Some analysis on what non-compiler support would be required for an llvm based EBC (UEFI) toolchain. TCWG-612 ARM TLS support in LLD: Initial support and tests for standard model upstreamed. There is still some work to be done for corner cases where LLD's relaxations will cause assertion failures. Static linking also needs some work as the TLS module index needs to be written into the GOT without a dynamic relocation. I have a prototype fix that needs cleaning up and tests written. Did some experiments with static linking and TLS to work out what I'll need to look at next. Discovered GNU ifunc support when static linking is not working. Did some thinking about what would be needed to support C++ exceptions in LLD for ARM. This is probably the next major chunk of work as supporting exceptions is needed when static linking against the C library startup code. == Plans == Plans for next 4 weeks: On Sabbatical back on the 22nd August. Will probably have limited access to email if there is anything urgent.
