// After preprocessor defs are handled, what this should do is expose the following types:
|
||
|
|
// SInt16 - Signed 16-bit integer
|
||
|
|
// UInt16 - Signed 16-bit integer
|
||
|
|
// UInt15 - Unsigned 15-bit integer
|
||
|
|
// SInt32 - Signed 32-bit integer
|
||
|
|
// UInt31 - Unsigned 31-bit integer
|
||
|
|
// AInt16 - 16-bit integer of unknown signedness (only used for storage)
|
||
|
|
// Int16CompFlag - Comparison flags from comparing 16-bit integers
|
||
|
|
// Int32CompFlag - Comparison flags from comparing 32-bit integers
|
||
|
|
// FloatCompFlag - Comparison flags from comparing 32-bit floats
|
||
|
|
//
|
||
|
|
// The reason for these distinctions are that depending on the instruction set, signed or unsigned versions of certain ops
|
||
|
|
// (particularly max, min, compares, and right shift) may not be available. In cases where ops are not available, it's
|
||
|
|
// necessary to do high bit manipulations to accomplish the operation with 16-bit numbers. The 15-bit and 31-bit uint types
|
||
|
|
// can elide the bit flips if unsigned versions are not available.
