[Qemu-devel] [PATCH v5 00/19] TCG cross-tb optimizations

[Richard Henderson]

Changes since Emilio's v4:
  * Fold tcg/i386 exit_tb 0 to the epilogue we created for goto_ptr.
  * Drop gen_jr in favor of DISAS_EXIT for target/arm.
  * Backend support for ppc, aarch64, sparc, s390.
  * Fix 3 build failures that appear on sparc v8plus (64-bit ilp32).

I attempted to throw together an x32 environment to validate
x86_64 ilp32, which ought to have had the same problems as sparc,
but my patience was exhausted by gentoo misconfigury.  I may try
that again later, but not now.
