The addrl used to compare with SoftTLB entry should be sign-extended in common case, and it will cause constant failing in SoftTLB comparisons for the addrl whose address is over 0x80000000 on the emulation of 32-bit guest on 64-bit host. This is an important performance bug fix. Spec2000 gzip rate increase from ~45 to ~140 on Loongson 3A4000 (MIPS compatible platform).
