[Qemu-devel] [PATCH v2 00/26] tcg-aarch64 improvements, part 3

[Richard Henderson <rth@twiddle.net>]

Changes from v1:
  * Frame pointer backtrace linkage retained.  Not that gdb seems to
    use this at all; the tcg_register_jit patch is still required in
    order to get a proper backtrace.
  * Several patches re-ordered in order to reduce churn.  Especially
    the qemu_ld/st related patches.
  * Avoid using ADRP for 32-bit values.  It would be exceedingly rare
    to save an instruction for this case.
  * Don't merge tcg_out_movr{,_sp} with their callers.

I believe I've incorporated all of Claudio's feedback from v1.
