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.
