If the insn ;; is a left shift double, bits are taken from the high order bits of ;; reg, else if the insn is a shift right double, bits are taken from the ;; low order bits of reg. So if %eax is "1234" and %edx is "5678", ;; "shldl $8,%edx,%eax" leaves %edx unchanged and sets %eax to "2345". ;; ;; Since sh[lr]d does not change the `reg' operand, that is done ;; separately, making all shifts emit pairs of shift double and normal ;; shift. Since sh[lr]d does not shift more than 31 bits, and we wish to ;; support a 63 bit shift, each shift where the count is in a reg expands ;; to a pair of shifts, a branch, a shift by 32 and a label. ;; ;; If the shift count is a constant, we need never emit more than one ;; shift pair, instead using moves and sign extension for counts greater ;; than 31.
