This hook must be implemented to lower outgoing return values, described by \p Val, into the specified virtual registers \p VRegs. This hook is used b

Match a ConstantFP or splatted ConstantVector, binding the specified pointer to the contained APFloat.

Match APFloat while allowing undefs in splat vector constants.

Match APFloat while forbidding undefs in splat vector constants.

Match a ConstantInt or splatted ConstantVector, binding the specified pointer to the contained APInt.

Match APInt while allowing undefs in splat vector constants.

Match an integer or vector with any integral constant. For vectors, this includes constants with undefined elements.

Match an arbitrary binary operation and ignore it.

Matches any compare instruction and ignore it.

Match an arbitrary ConstantFP and ignore it.

Match an arbitrary ConstantInt and ignore it.

Like m_Specific(), but works if the specific value to match is determined as part of the same match() expression. For example: m_Add(m_Value(X), m_Spe

Match a float 1.0 or vector with all elements equal to 1.0.

Match a finite FP constant, i.e. not infinity or NaN. For vectors, this includes constants with undefined elements.

Match a finite non-zero FP constant. For vectors, this includes constants with undefined elements.

Match an arbitrary immediate Constant and ignore it.

Match a positive or negative infinity FP constant. For vectors, this includes constants with undefined elements.

Match an instruction, capturing it if we match.

Match an integer or vector with only the low bit(s) set. For vectors, this includes constants with undefined elements.

Match an integer or vector with values having all bits except for the high bit set (0x7f...). For vectors, this includes constants with undefined elem
