[PATCH v7 0/9] target/arm: pc-relative translation blocks

Posted by Richard Henderson 1 year, 7 months ago

This is the Arm specific changes required to reduce the
amount of translation for address space randomization.

Changes for v7:
  * Remove read_pc in patch 8.
  * Add DisasLabel and inlines to generate/emit,
    cleaning up the management of pc_save.
  * Restore pc_save after tcg_remove_ops_after.
