Paul Mackerras 45f62159f3 powerpc: Wrap register number correctly for string load/store instructions ... Michael Ellerman reported that emulate_loadstore() was trying to access element 32 of regs->gpr[], which doesn't exist, when emulating a string store instruction. This is because the string load and store instructions (lswi, lswx, stswi and stswx) are defined to wrap around from register 31 to register 0 if the number of bytes being loaded or stored is sufficiently large. This wrapping was not implemented in the emulation code. To fix it, we mask the register number after incrementing it.
