Hello, A limitiation by some other software means that I am working with gcc .3 .4 1 And I am therefore using the accompanying manuals. I do not understand the gcc internal documentation on the integer_cst expression trees. An expression is given to calculate the value of the constant: ( (TREE_INT_CST_HIGH(e) << HOST_BITS_PER_WIDE_INT) + TREE_INT_CST_LOW(e)) Using the expression, what is wrong in the following example: Example ----------- Given integer = 5 HOST_BITS_PER_WIDE_INT = 4 //just an example HOST_WIDE_INT is a type for which the integers are HOST_BITS_PER_WIDE_INT bits long. Binary representation of given integer is 0|1|0|1 TREE_INT_CST_HIGH = 0|0|0|1 TREE_INT_CST_LOW = 0|0|0|1 ----------- This definitely does not yield 5 if I apply that expression, so, I imagine there is something wrong somewhere. If it does, then maybe I did not understand the expression? Could anybody please tell me where my thinking went wrong? Thanks a lot, Primrose Mbanefo
