Member Function Documentation

areInlineCompatible()

bool AArch64TTIImpl::areInlineCompatible ( const Function * Caller, const Function * Callee ) const

overridevirtual

The compiler must not inline when that may alter the behavior of the program.

This is especially relevant around SME which implements different runtime modes and maintains external state through attributes.

The compiler must not inline when:

• The module is compiled with 'strict-fp' and the called function implements a different FP environment than the caller.

• The called function has operations that are incompatible in the mode of the caller, e.g.:

  • inlining non-streaming-only instructions into a streaming function.
  • inlining streaming-only instructions into a non-streaming function.

  Inline asm blocks must be entered and exited in the [streaming] mode of the parent function. There is no language-level mechanism to inform the compiler that a particular inline asm block is streaming compatible, so the compiler must reject this as a candidate for inlining.

• The called function contains vscale-dependent operations but otherwise does not take/return VL-dependent arguments (see definition in the ACLE (Arm C/C++ Language Extensions)).
• The called function sets up new ZA/ZT state into a function that already has ZA or ZT state, as that is not valid as per the ACLE.

The compiler should not inline when:

• The called function has fixed-length vectors and the caller is in streaming mode, as this may cause performance regressions. This should never result in an error to be reported.
• The called function sets up new ZA/ZT state into a function that has no ZA and no ZT state, as the compiler currently cannot transfer the attribute to the caller. It may also impact performance, but that should be covered by AArch64TTIImpl::getInlineCallPenalty().

If a callee is incompatible with its caller, then the inliner should prevent inlining. LLVM's alwaysinline attribute has no impact on whether a callee is inline compatible. This is especially relevant with streaming-mode attributes, where alwaysinlineing a function into a function with a different streaming mode may otherwise impact runtime behaviour.

shouldConsiderAddressTypePromotion()

bool AArch64TTIImpl::shouldConsiderAddressTypePromotion ( const Instruction & I, bool & AllowPromotionWithoutCommonHeader ) const

overridevirtual

See if I should be considered for address type promotion.

We check if I is a sext with right type and used in memory accesses. If it used in a "complex" getelementptr, we allow it to be promoted without finding other sext instructions that sign extended the same initial value. A getelementptr is considered as "complex" if it has more than 2 operands.
