From 3213da7b9539581c6df95f8ced5b09d0b02d425f Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Sat, 5 Oct 2024 22:09:54 +0000 Subject: tcg/ppc: Use TCG_REG_TMP2 for scratch index in prepare_host_addr In tcg_out_qemu_ldst_i128, we need a non-zero index register, which we then use as a base register in several address modes. Since we always have TCG_REG_TMP2 available, use that.
