[Qemu-devel] [PATCH v2 00/14] target/sh4: misc fixes, cleanup and optimizations

[Aurelien Jarno]

This patch series try to improve the SH4 target by using the (more or
less) recently introduced TCG features. It also fixes some issues spot
when writting the patches (linking of TB with different flags, SH4-A
specific instructions allowed on SH4) and correctly trap unaligned
accesses.

v2:
- Add some comments in the struct DisasContext declaration, as suggested
  by Philippe Mathieu-Daudé
- Add Reviewed-by entries
