Toolchain for cross compiling

by Suresh Nulu

Hi, I am new to toolchains. I would like to know information on building toolchains for different architectures. My objective is to build a cross compiling toolchain for AARCH64 BE target on the RHEL7.6 build system. It would be great if you can give me pointers on how to compile toolchains. Do we have any Wiki pages on building linaro toolchains for different architectures? Appreciate your help. Regards Suresh

[ACTIVITY] report week ending 9 Oct

by Peter Maydell

Progress: * VIRT-65 [QEMU upstream maintainership] + another round of code review and target-arm queue wrangling + found and fixed an edge-case bug in setting Q flag in SMLAD insn + fixed a GICv3 emulation bug where we didn't ever raise maintenance interrupts * VIRT-364 [QEMU support for ARMv8.1-M extensions] + went through Arm ARM and identified exactly what the "v8.1M changes which aren't part of a named architectural feature" are (for QEMU-409 subtask) + implemented some parts of NOCP handling that were left as TODO comments for being v8.1M-specific + implemented conditional-select insns (CSEL, CSINC, CSINV, CSNEG) + implemented low-overhead-loops and branch-future (in the 'trivial' don't-cache-anything way the architecture permits) thanks -- PMM
