Returns true if the function contains operations which will lower down to instructions which manipulate the stack pointer.

Returns true if valid debug info is present.

Return true if there are any SDDbgValue nodes associated with this SelectionDAG.

hasDefinitiveInitializer - Whether the global variable has an initializer, and any other instances of the global (this can happen due to weak linkage)

Returns true if the specified instruction has a delay slot which must be filled by the code generator.

Is domain available?

Return true if the reader encountered an error reading profiling data.

Return true if this global has an exact defintion.

Check if the given Module has any functions available for exporting in the index. We consider any module present in the ModulePathStringTable to have

Returns true if this instruction def operands have special register allocation requirements that are not captured by the operand register classes. e.g

Returns true if this instruction source operands have special register allocation requirements that are not captured by the operand register classes.

Return true if the target has BitExtract instructions.

Return the preferred operand type if the target has a quick way to compare integer values of the given size. Assume that any legal integer type can be

Return true the attributes exist for the function.

hasGC/getGC/setGC/clearGC - The name of the garbage collection algorithm to use during code generation.

Compute operand latency between a def of 'Reg' and a use in the current loop. Return true if the target considered it 'high'. This is used by optimiza

Return true if \p Other has the same sequence of operand bundle tags with the same number of operands on each one of them as this OperandBundleUser.

Returns true if the instruction has implicit definition.

Check if section name is present

A specialized version of hasFnAttrImpl for when the caller wants to know if an attribute's semantics are implied, not whether the attribute is actuall

Determine if there are is an inalloca argument. Only the last argument can have the inalloca attribute.

Definitions have initializers, declarations don't.

Returns true if the function contains any inline assembly.

Return true if this machine model includes an instruction-level scheduling model or cycle-to-cycle itinerary data.

Test whether this block must have its label emitted.

hasMatchingInput - Return true if this is an output constraint that has a matching input constraint.

Return true if this value has any metadata attached to it.

Return true if this instruction has any metadata attached to it.

Return true if this instruction has metadata attached to it other than a debug location.

Return true if multiple condition registers are available.

Returns true if the function is variadic and contains a musttail call.

Return true if this is a named struct that has a non-empty name.

Check if the instantiations in this group have a common mangled name.

Return true if the loop kernel has been scheduled.

Test if this operation's arguments and results are assumed not-infinite.

Test if this operation's arguments and results are assumed not-NaN.

Determine if the call can synchroize with other threads

These are accessors for each flag.

Return true if there is exactly one operand defining the specified register.

Return true if there is exactly one use of this node.

hasOneUse - Return true if there is exactly one instruction using the specified register.

Returns true if the function contains opaque dynamic stack adjustments.

Return true if this User has any operand bundles.

Return true if this operand bundle user contains operand bundles with tags other than those specified in \p IDs.

Do not optimize this function (-O0).

Optimize this function for size (-Os) or minimum size (-Oz).

Set if this instruction has an optional definition, e.g. ARM instructions which can set condition code if 's' bit is set.

Returns whether the struct has padding or not between its fields. NB: Padding in nested element is not taken into account.

Return true if the target supplies and combines to a paired load two loaded values of type LoadedType next to each other in memory. RequiredAlignment

Return true if attributes exists for the given argument

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

returns true if the specified virtual register is mapped to a physical register

Return true if this instruction requires *adjustment after instruction selection by calling a target hook. For example, this can be used to fill in AR

Returns true if N is a predecessor of any node in Worklist. This helper keeps Visited and Worklist sets externally to allow unions searches to be perf

Check whether this function has prefix data.

Return true if the function is annotated with profile data. Presence of entry counts from a profile run implies the function has profile annotations.

Check whether this function has prologue data.
