Check whether or not a diagnostic should be emitted when GlobalISel uses the fallback path. In other words, it will emit a diagnostic when GlobalISel

Report a parse error message.

Ensure that a label will be emitted after MI.

Ensure that a label will be emitted before MI.

Returns true if the target requires using the RegScavenger directly for frame elimination despite using requiresFrameIndexScavenging.

Returns true if the target requires post PEI scavenging of registers for materializing frame index constants.

Returns true if the target requires (and can make use of) the register scavenger.

Allows target to decide about the register class of the specific value that is live outside the defining block. Returns true if the value needs unifor

Returns true if the target wants the LocalStackAllocation pass to be run and virtual base registers used for more efficient stack access.

Grow the size of the operand list to accommodate the new number of clauses.

reservedRegsFrozen - Returns true after freezeReservedRegs() was called to ensure the set of reserved registers stays constant.

Reset the data structures used in the circuit algorithm.

Reset this candidate back to an empty one.

Reset the currently registered delegate - otherwise assert.

Reset state that changes when we handle different basic blocks. This currently includes: 1. The specific basic block we are generating a stack prote

Reset state that only changes when we switch functions. This currently includes: 1. FailureMBB since we reuse the failure code path for all stack pr

Resolve a frame index operand of an instruction to reference the indicated base register plus offset instead.

This function is used by classes that refer to other variables which may not be defined at the time the expression is formed. If a value is set for th

restoreCalleeSavedRegisters - Issues instruction(s) to restore all callee saved registers and returns true if it isn't possible / profitable to do so

Sets the current insert point to a previously-saved location.

Add reference to DV.

Move tracking from one reference to another. Semantically equivalent to \c untrack(MD) followed by \c track(New), except that ownership callbacks are

Determine if the parameter or return value is marked with NoAlias attribute.

Determine if the return value is marked with NoAlias attribute.

Reverses the branch condition of the specified condition list, returning false on success and true if it cannot be reversed.

Transform a lanemask given for a virtual register to the corresponding lanemask before using subregister with index \p IdxA. This is the reverse of co

Allow the target to reverse allocation order of local live ranges. This will generally allocate shorter local live ranges first. For targets with many

Rewind byval registers tracking info.

roots_begin/roots_end - Iterators for all roots in the function.

Run the analysis pass and create our proxy result object. This doesn't do any interesting work; it is primarily used to insert our proxy result objec

Run the analysis pass and create our proxy result object. Nothing to see here, it just forwards the \c OuterAM reference into the result.

Run this pass over some unit of IR. This pass can be run over any unit of IR and use any analysis manager provided they satisfy the basic API require

The model delegates to the \c PassT::run method. The return is wrapped in an \c AnalysisResultModel.

Emit the specified function out to the OutStreamer.

Returns true if this and MBB belong to the same section.

Returns the current insert point, clearing it in the process.

Returns the current insert point.

Spill the register so it can be used by the register scavenger. Return true if the register was spilled, false otherwise. If this function does not sp

Save a string in the Index. Use before passing Name to getOrInsertValueInfo when the string isn't owned elsewhere (e.g. on the module's Strtab).

Scheduler callback to notify that a new subtree is scheduled.

As each node is scheduled, this method is invoked. This allows the priority function to adjust the priority of related unscheduled nodes, for example

Set the abbreviation number for this DIE.

More friendly way to set an action for common types that have an LLT representation. The LegacyLegalizeAction must be one for which NeedsLegalizingToD

Sets actions for all bit sizes on a particular generic opcode, type index and scalar or pointer type.

Set alignment of the basic block.

for use only in special circumstances that need to generically transform a whole instruction (eg: IR linking and vectorization).
