hasRegClassConstraint - Returns true if the flag contains a register class constraint. Sets RC to the register class ID.

Returns true if Reg contains RegUnit.

hasReservedCallFrame - Under normal circumstances, when a frame pointer is not required, we reserve argument space for call sites in the function imme

Return true if target has reserved a spill slot in the stack frame of the given function for the specified register. e.g. On x86, if the frame registe

Returns true when resource information for this block has been computed.

Return true if the attribute exists for the return value.

Return true if attributes exist for the return value.

Return true if both pointer types have the same element type. Two opaque pointers are considered to have the same element type, while an opaque and a

Check the optional flags for equality.

Check if this global has a custom object file section. This is more efficient than calling getSection() and checking for an empty string.

This method may be called any time after instruction selection is complete to determine if there is a call to builtin \@llvm.experimental.stackmap.

Return true if there are any stack objects in this function.

Returns the name of the symbol used to emit stack probes or the empty string if not applicable.

True if stack realignment is required and still possible.

Return true if the target can handle a standalone remainder operation.

Determine if the function returns a structure through first or second pointer argument.

Determine if the call returns a structure through first pointer argument.

Returns true if subregister liveness information is available.

Return true if any of the successors have probabilities attached to them.

Return true if the specified TargetRegisterClass is a proper super-class of this TargetRegisterClass.

Returns true if RC is a super-class of or equal to this class.

Returns true if the function contains a tail call.

If true, the target has custom DAG combine transformations that it can perform for the specified node.

Check whether this has a trivial destructor.

Return whether any name in the profile contains ".__uniq." suffix.

hasUniqueInitializer - Whether the global variable has an initializer, and any changes made to the initializer will turn up in the final executable.

Accessor Methods for CatchSwitch stmt

Returns true if the function calls the llvm.va_start intrinsic.

Return true if this DAG supports VReg liveness and RegPressure.

Return true if this DAG supports VReg liveness and RegPressure.

Returns true if the height resources have been computed from the trace below this block.

Return true if there is a value handle associated with this value.

This method may be called any time after instruction selection is complete to determine if the stack frame for this function contains any variable siz

Return true if the target has a vector blend instruction.

ignorablePassImpl - Can be overriden in subclasses to refine the list of which passes we want to include.

True if the register allocator should use the allocation orders exactly as written in the tablegen descriptions, false if it should allocate the speci

Check if the given instruction I should be ignored by the packetizer.
