Test whether the LegalityQuery matches.

Hook for users to check if an ISA trait matches. The trait is described as the string that got parsed and it depends on the target and context if this

Insert defining instruction(s) for a pointer to FrameIdx before insertion point I. Return materialized frame pointer.

Returns true if the definition of this global may be replaced by a differently optimized variant of the same source level function at link time.

Return true if the target may be able emit the call instruction as a tail call. This is used by optimization passes to determine if it's profitable to

Check whether a string looks like an old loop attachment tag.

Return true if this instruction may read or write memory.

Return true if we don't have any memory operands which described the memory access done by this instruction. If this is true, calling code must be co

Access to memory operands of the instruction. If `memoperands_begin() == memoperands_end()`, that does not imply anything about whether the function

Update the attributes of the current profile from the attributes specified. An error is returned if IR and FE profiles are mixed.

Allow store merging for the specified type after legalization in addition to before legalization. This may transform stores that do not exist earlier

Return true if the MachineInstr modifies (fully define or partially define) the specified register. NOTE: It's ignoring subreg indices on virtual regi
