BitsContainNoUserData()

static bool BitsContainNoUserData ( QualType  Ty, unsigned  StartBit, unsigned  EndBit, ASTContext &  Context  )

static

BitsContainNoUserData - Return true if the specified [start,end) bit range is known to either be off the end of the specified type or being in alignment padding.

The user type specified is known to be at most 128 bits in size, and have passed through X86_64ABIInfo::classify with a successful classification that put one of the two halves in the INTEGER class.

It is conservatively correct to return false.

rewriteInputConstraintReferences()

static void rewriteInputConstraintReferences ( unsigned  FirstIn, unsigned  NumNewOuts, std::string &  AsmString  )

static

Rewrite input constraint references after adding some output constraints.

In the case where there is one output and one input and we add one output, we need to replace all operand references greater than or equal to 1: mov $0, $1 mov eax, $1 The result will be: mov $0, $2 mov eax, $2
