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
== Progress ==
* GCC upstream validation:
- reported several regressions
- committed minor cleanup fixes
- fixed broken trunk build with gcc-4.8
* GCC
- PR96767: no feedback
- PR96770: no feedback
- patch for C++ thunks with -mpure-code and cortex-m0: sent updated patch
- Neon intrinsics: sent patch to implement vceqq, vceqz and vceqzq for p64.
* benchmarking:
- Scripts to run coremark on stm32 now merged, debugging issues. No
progress this week.
* infra:
- debugging issues with our docker containers
== Next ==
* GCC/cortex-M testing improvements & fixes
* cortex-m benchmarking
* MVE intrinsics improvements
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
