[PATCH for-8.2 v2 0/7] tcg/ppc: Support power10 prefixed instructions

Posted by Richard Henderson 9 months ago

Emit one 64-bit instruction for large constants and pc-relatives.
With pc-relative addressing, we don't need REG_TB, which means we
can re-enable direct branching for goto_tb.

Changes for v2:
  * Merged Nick's adjustments for goto_tb.  Only patch B/NOP,
    falling through to PLD for indirect branch; drop PLA option.
  * Fix sx typo in patch 3 (jordan).
