#11 shl lowered incorrectly to constant 1 year, 5 months ago

Comment by ~mpu on ~mpu/qbe

It's documented behavior. "The shifting amount is taken modulo the size of the result type". 72 mod 64 == 8 and 2^8 == 256, so the code behaves according to spec. The constant folder even goes through a bit of sweat to guarantee that: https://c9x.me/git/qbe.git/tree/fold.c#n392

The rationale for this choice is that it's the natural behavior of all qbe targets. So shl in qbe is a simple machine shift left.
