Extend the live range of @p LR to reach all uses of Reg. All uses must be jointly dominated by existing liveness. PHI-defs are inserted as needed to

Return the increase in code size needed to predicate a contiguous run of NumInsts instructions.

Emit an alloca address in a register using target-specific logic.

Emit a constant in a register using target-specific logic, such as constant pool loads.

Emit the floating-point constant +0.0 in a register using target- specific logic.

Get function summary flags.

This should only be called when using deferred_insert. This asserts that the WorklistMap is empty, and then inserts all the elements in the Worklist i

Fix up the placeholder we may add in genAlternativeCodeSequence().

Allow targets to perform final scheduling actions at the level of the whole MachineFunction. By default does nothing.

findAbstractScope - Find an abstract scope or return null.

Returns the call target map collected at a given location. Each location is specified by \p LineOffset and \p Discriminator. If the location is not fo

Finds the unique case value for a given successor. Returns null if the successor is not found, not unique, or is the default case.

Search all of the case values for the specified constant. If it is explicitly handled, return the case iterator of it, otherwise return default case i

Returns the FunctionSamplesMap at the given \p Loc.

Recursively traverses all children, if the total sample count of the corresponding function is no less than \p Threshold, add its corresponding GUID t

findInlinedScope - Find an inlined scope for the given scope/inlined-at.

findLexicalScope - Find regular lexical scope or return null.

Get an iterator pointing to the IdxMBBPair with the biggest SlotIndex that is greater or equal to \p Idx.

findNearestCommonDominator - Find nearest common dominator basic block for basic block A and B. If there is no such block then return NULL.

Wrapper for findRegisterDefOperandIdx, it returns a pointer to the MachineOperand rather than an index.

Wrapper for findRegisterUseOperandIdx, it returns a pointer to the MachineOperand rather than an index.

Return the number of samples collected at the given location. Each location is specified by \p LineOffset and \p Discriminator. If the location is not

Find the summary for ValueInfo \p VI in module \p ModuleId, or nullptr if not found.

Given an build_vector op \p BV and a start bit and size, try to find the origin of the value defined by that start position and size. \returns a regi

Given an concat_vector op \p Concat and a start bit and size, try to find the origin of the value defined by that start position and size. \returns a

Try to find a source of the value defined in the def \p DefReg, starting at position \p StartBit with size \p Size. \returns a register with the reque

Internal implementation for findValueFromDef(). findValueFromDef() initializes some data like the CurrentBest register, which this method and its call

Given an G_INSERT op \p MI and a start bit and size, try to find the origin of the value defined by that start position and size. \returns a register

Called after the assembly for the module is generated by the AsmPrinter (but before target specific hooks)

Returns true if the specified type fits in a native integer type supported by the CPU. For example, if the CPU only supports i32 as a native integer

Target-dependent implementation for foldMemoryOperand. Target-independent code in foldMemoryOperand will take care of adding a MachineMemOperand to th

Move the internal MBB iterator and update register states until it has processed the specific iterator.

Determine the relative position of the fragments passed in. Returns -1 if this is entirely before Other, 0 if this and Other overlap, 1 if this is ent

Check if fragments overlap between a pair of FragmentInfos.

Frequency of the insertion point. \p P is used to access the various analysis that will help to get that information, like MachineBlockFrequencyInfo.

Get an attribute from a raw pointer created by getRawPointer.

Initializes case iterator for given SwitchInst and for given successor index.

For some targets, an LLVM struct type must be broken down into multiple simple types, but the calling convention specifies that the entire struct must

range adapter for gc arguments

Returns an iterator to the begining of the argument range describing gc values for the statepoint.

Return an end iterator for the gc argument range

range adapter for GC transition arguments

Return true when the decision to generate FMA's (or FMS, FMLA etc) rather than FMUL and ADD is delegated to the machine combiner.
