[Qemu-devel] [PATCH v2 00/12] target-arm: A64 decoder, foundation plus branches

[Peter Maydell]

Round two of the first-chunk of A64 decoder work, updated
following code review.

Contents:
 * the new decoder skeleton,
 * gdbstub support for FP insns
 * a patch from me which gives the A64 decoder its own
   gen_intermediate_code_internal() loop for simplicity
 * the branch related patches from Alex's series, inserted into
   the new decoder skeleton

These patches sit on top of the v8 KVM control patchset I posted
last week. You can find a git tree with them here:

web UI:
 
https://git.linaro.org/gitweb?p=people/pmaydell/qemu-arm.git;a=shortlog;h=refs/heads/a64-first-set

Changes v1->v2:
 * fixed a non-prettified insn pattern format in a comment
 * flip order of goto_tbs in cond-branch, test&branch, cmp&branch
 * read_cpu_reg() now returns a (trashable) TCGv_i64 rather than
   requiring one to be passed in
