// Purpose:
|
||||
// This default implementation assumes that all sub-word data items use
|
||||
// space equal to optSizeForSubWordData, and all other primitive data
|
||||
// items use space according to the type.

//

// Round integral values smaller than SubWordDataSize up to SubWordDataSize

|
||||
Ty->getPrimitiveSize() < DataLayout.getSubWordDataSize())
|
||||
return DataLayout.getSubWordDataSize();
|
||||
// All integer types smaller than ints promote to 4 byte integers.
|
||||
