[Qemu-devel] [PATCH 00/11] target/sh4 improvments

[Richard Henderson <rth@twiddle.net>]

This fixes two problems with atomic operations on sh4,
including an attempt at supporting the user-space atomics
technique used by most sh-linux-user binaries.

This is good enough to run the one occurrence in linux-user-test-0.3.
I'm still downloading enough of a cross environment to be able to run
more recent sh4 binaries.  Including the one in the LP bug report.

Thoughts and more extensive testing appreciated.
