Pre/post-increment addressing mode in LSR
...post-increment addressing modes. This is because the target hook `isLegalAddressingMode` in TargetTransformInfo.h doesn’t allow for pre- and post-increment. There is in fact a comment to that effect on the function prototype: “TODO: handle pre/postinc as well” (see http://llvm.org/docs/doxygen/html/TargetTransformInfo_8h_source.html line 310).
So I was wondering: is there a way to work around this limitation? And are there any plans to add support for pre- and post-increment addressing modes?
Thanks in advance for any help on this.
