3594	Bitwise operators in MetaModelica are broken	Per Östlund	Martin Sjölund	"The bitwise operators in MetaModelica seem to be completely broken, e.g.:
{{{#!mo
intBitLShift(1, 1))   // 1 << 1 = 2,   OMC says 2. ok!
intBitLShift(1, 2))   // 1 << 2 = 4,   OMC still says 2!
intBitLShift(32, 1))  // 32 << 1 = 64, OMC says 2^37!?
intBitRShift(1, 1))   // 1 >> 1 = 0,   OMC says 0. ok!
intBitRShift(2, 1))   // 2 >> 1 = 1,   OMC says 0.
intBitRShift(64, 5))  // 64 >> 5 = 2,  OMC says 0.
intBitOr(1, 2))       // 1 | 2 = 3,    OMC says 1.
intBitAnd(7, 4))      // 7 & 4 = 4,    OMC says 7.
}}}
The code generation just generates normal C operators for these, so I'm guessing the issue is due to some fun boxing/unboxing stuff. The operators are not actually used in the compiler at the moment, which would explain why noone's noticed before."	defect	closed	critical	1.9.4	MetaModelica		fixed
