From cca1af8c4d2ef6449fd61494ba2cb087b838011c Mon Sep 17 00:00:00 2001 From: Aurelien Jarno Date: Tue, 9 Feb 2010 22:54:22 +0100 Subject: tcg/mips: fix crash in tcg_out_qemu_ld() The address register is overriden when it corresponds to v0 and the fast path is taken, which leads to a crash. Fix that by using the a0 register instead.
