Intersect this set with another in place. This is a mutating operation on this preserved set, removing all preserved passes which are not also preser

Return true if any type of remarks are enabled for this pass.

Whether this is bitwise logic opcode.

isDead - Returns true if this is a dead def kill slot.

Return true if the extension represented by \p I is free. Unlikely the is[Z|FP]ExtFree family which is based on types, this method can use the context

isFPImm - Tests if this is a MO_FPImmediate operand.

Return true if the value is infinity

Return true if this is an integer or a vector integer type.

Layout endianness...

Test if this node is a memory intrinsic (with valid pointer information). INTRINSIC_W_CHAIN and INTRINSIC_VOID nodes are sometimes created for non-mem

Return true if the value is a NaN.

Return true if the sign bit is set.

NOTE: This is soft-deprecated. Please use `isZero()` instead.

This is just a convenience method to make client code smaller for a common case. It also correctly performs the comparison without the potential for a

Return true if this is a type with an identity that has no body specified yet. These prints as 'opaque' in .ll files.

isPowerOf2_32 - This function returns true if the argument is a power of two > 0. Ex. isPowerOf2_32(0x00100000U) == true (32 bit edition.)

isRegMask - Tests if this is a MO_RegisterMask operand.

Check if node is fully resolved. If \a isTemporary(), this always returns \c false; if \a isDistinct(), this always returns \c true. If \a isUniqued

isShiftedMask_64 - This function returns true if the argument contains a sequence of ones with the remainder zero (64 bit version.)

Check if this ValueMapping is valid.

Check for M6809/HD6309 TFR/EXG instruction for valid register

Match APInt while forbidding undefs in splat vector constants.

Match an integer or vector with all bits set. For vectors, this includes constants with undefined elements.

Match an arbitrary basic block value and ignore it.

Match an arbitrary Constant and ignore it.

Match an arbitrary ConstantExpr and ignore it.

Return true if this instruction could possibly read or modify memory.

Return true if this instruction could possibly raise a floating-point exception. This is the case if the instruction is a floating-point instruction
