Subject: [Qemu-devel] [PATCH 0/2] tcg constant pool fixups
Date: Thu, 26 Oct 2017 17:27:02 +0200	[thread overview]
Message-ID: <20171026152704.24525-1-richard.henderson@linaro.org> (raw)

As noted by Laurent in private mail, foo-linux-user is currently
broken on aarch64 host in unususal circumstances.  By inspection,
the same thing could happen for armv6 host.  My testing is always
on armv7 hardware, so I wouldn't have seen this.

With that fixed, the s390x code can be simplified a bit to take
advantage of this.

If the s390x maintainers could test this, I would appreciate it. 
The test case is

  ./i386-linux-user/qemu-i386 -B 0x111231000 ./some-static-i386

e.g. using the binary in the busyboxes tarball linked from

  https://wiki.qemu.org/Testing#User_mode_emulation

although any staticly linked binary would work.
