--- Comment #41 from Mark Wielaard <m...@klomp.org> ---
Hoping that the JRS FIXME for ldbrx (Load Doubleword Byte-Reverse Indexed) was
a hint that memcheck would be helped by a single double-word load plus
Iop_Reverse I hacked up:
DIP("ldbrx r%u,r%u,r%u\n", rD_addr, rA_addr, rB_addr);
IRTemp dw1 = newTemp(Ity_I64);
IRTemp dw2 = newTemp(Ity_I64);
assign( dw1, load( Ity_I64, mkexpr(EA)) );
assign( dw2, unop(Iop_Reverse8sIn64_x1, mkexpr(dw1)) );
putIReg( rD_addr, mkexpr(dw2) );
But the ppc backend doesn't handle Iop_Reverse8sIn64_x1, so that didn't really
go anywhere for now.
