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

+ implemented some parts of NOCP handling that were left as TODO comments
for being v8.1M-specific

Progress:
* VIRT-65 [QEMU upstream maintainership]
+ rc3 sent out. Optimistically hoping for release next week.
+ rebased the patchset converting QAPI doc-comments to rST
+ Fixed a bug in syndrome register values for copro insns trapped
from AArch32 to AArch64
* VIRT-364 [QEMU support for ARMv8.1-M extensions]
+ Finished and sent out the patchset that cleans up the coproc
insn decode and corrects the NOCP handling
+ With assistance from RTH, figured out how to use gvec helpers
to implement fp16 for various Neon insns. Added fp16 support to
20 or so insns; still have 15 or so to go.
thanks

Progress:
* VIRT-65 [QEMU upstream maintainership]
+ More release herding...
+ Sent fixes for some bugs:
- assertion in the imx_epit timer device when guest soft-reset it
- netduino2/netduinoplus2 forgot to configure system clock scale so
using SysTick in "run at CPU frequency" mode would hang
- most M-profile boards failed to make AIRCR.SYSRESETREQ actually
reset the system
* VIRT-364 [QEMU support for ARMv8.1-M extensions]
+ More progress with fp16: all the VFP insns now handled, including
the new-for-fp16 ones. Still to do: all of Neon...
+ Spent some time working through the details of NOCP vs UNDEF
in the M-profile coprocessor space for the various revisions
of the architecture. v8.1M adjusts things a bit in this area
and I want to clean up this bit of QEMU's current code and
get the v8.1M bits right.
Fact: next Monday (3rd August) will be the 10th anniversary
of my secondment into Linaro!

[VIRT-327 # Richard's upstream QEMU work ]
Misc patch review.
[GCC]
I looked into Adhemerval's libgomp-scalability patch set. The code looks good,
and I can't see anything wrong.
The cancel-parallel-2 test that's reported to regress, does, sometimes. It
never fails for me on qemu-test (aarch64, tx1). It *only* fails under the
dejagnu test harness on x86_64 and ppc64le. When run by hand it succeeds,
always. I cannot explain that at all. I've run the testsuite with
OMP_DEBUG_ENV=verbose and see that the dejagnu environment is as expected.
Anyway, I can't make forward progress because I can't reproduce the problem
under controlled conditions.

Progress:
* VIRT-65 [QEMU upstream maintainership]
+ More wrangling of release stuff and unreliable infrastructure.
* VIRT-364 [QEMU support for ARMv8.1-M extensions]
+ Managed to find a few days to put in some more work pushing fp16
handling forwards. I now have implementations of fp16 for most of
the VFP insns (still todo: VCVT, VSEL, VMAXNM/VMINNM, VRINT*; then
the few insns that are new-for-fp16. Then all of Neon, which is larger.)
thanks
