[PATCH] D23155: Power9 - Part-word VSX integer scalar loads/stores and sign extend instructions

[Nemanja Ivanovic via llvm-commits]

nemanjai updated this revision to Diff 72834.
nemanjai added a comment.

Moved the definition of the static functions that were defined in 3 places to the class definition.
Clarified the comment regarding the handling of VMX (Altivec) registers.
Rebased the patch on a more recent revision (r282478) since a lot of files and behaviour changed.

Please note: there are a couple of FIXME's in the test cases. The reason for this is that there are a number of instructions we exploited recently that can match BUILD_VECTOR nodes. Some of the previously committed patches make the code in this patch unable to match a BUILD_VECTOR node under very specific conditions. I have a subsequent patch coming up which will take all the recent changes into account and produce optimal code for BUILD_VECTOR nodes for both Power8 and Power9.
