// Non-constant rotate detection. // We use shiftIsBounded to make sure that neither of the shifts are >64. // Note: these rules are subtle when the shift amounts are 0/64, as Go shifts // are different from most native shifts. But it works out.

(Not x) => (XOR (MOVDconst [1]) x) // shifts // hardware instruction uses only the low 6 bits of the shift // we compare to 64 to ensure Go semantics for large shifts // Rules about rotates with non-const shift are based on the following rules, // if the following rules change, please also modify the rules based on them. // check shiftIsBounded first, if shift value is proved to be valid then we // can do the shift directly.

a <a href="#Run_time_panics">run-time panic</a> occurs. The shift operators implement arithmetic shifts if the left operand is a signed integer and logical shifts if it is an unsigned integer. There is no upper limit on the shift count. Shifts behave as if the left operand is shifted <code>n</code> times by 1 for a shift count of <code>n</code>.

// S{HL, HR, AR}x: shift operations // SHL: shift left // SHR: shift right logical (0s are shifted in from beyond the word size) // SAR: shift right arithmetic (sign bit is shifted in from beyond the word size) // arg0 is the value being shifted // arg1 is the amount to shift, interpreted mod (Q=64,L=32,W=32,B=32) // (Note: x86 is weird, the 16 and 8 byte shifts still use all 5 bits of shift amount!)
