For me the miscompilation is in jkdmem_, where we end up allocating the same

This is not needed in the patch as it is only used for x86_64 targets.
Should you make sure nobody specifies the big-endian target:
aarch64_be-w64-mingw32 ?
Thanks,

Hello,
We would like to take your attention to the review of changes for the
new GCC target, aarch64-w64-mingw32. The new target will be
supported, tested, added to CI, and maintained by Linaro. This marks
the first of three planned patch series contributing to the GCC C
compiler's support for

Thread model: posix
Supported LTO compression algorithms: zlib zstd

This patch adds support for MVE Tail-Predicated Low Overhead Loops by using the
doloop funcitonality added to support predicated vectorized hardware loops.

This patch fixes the erroneous use of a mode attribute without a mode iterator
in the pattern and removes unused unspecs and iterators.

For statically linked binaries one wants to keep track of external
