[Qemu-devel] target-arm: aarch64: ask for suggestion, a few insn implementations for review.
Mon, 23 Dec 2013 16:09:28 +0800
I'm writing this letter mainly for help and suggestion.
I'm using qemu-aarch64 from matz's repository, which actually is
with matz's repo, and trying to build a small gentoo rootfs, I
encountered a problem with gcc-4.9.0 and if only commit is
included, I have reported to gcc upstream, for more information can be
The problem is that there are still a few insn implementations
missing in matz's repo,
so I try to implement them myself. I'm not familiar with qemu tcg,
so those patches probably more than a hack, it would be great if
anyone can help to review, whether I'm doing this correct or not (I'm
not seeking for upstreaming those patches).
yes, I've seen aarch64's work is heading for upstream, and I jumped
a little ahead..
so, let me know what the best i can do.
