...b-registers around within a 128 bit register. By the time the register allocator runs the code looks like: 92L %reg16402:dsub0<def> = DEF64.. %reg16402<imp-def>, QPR:%reg16402.... 116L %reg16405:sub0<def> = COPY %reg16402:sub1, %reg16405<imp-def>; QPR:%reg16405,16402 124L %reg16413:sub0<def> = COPY %reg16405:sub0<kill>; QPR:%reg16413,16405 .... stuff .... 468L %reg16460:sub3<def> = COPY %reg16402:sub0<kill>; QPR:%reg16460,16402 dsub0/dsub1 are 64-bit subregs and sub0/1/2/3 are 32 bit subregs. DEF64 is just representative of a 64 bit ALU operation....
