[llvm-commits] [PATCH] Shufflevector crash on ARM, take 2

[James Molloy]

Hi,

A while back I posted a patch to fix a crash codegenning certain
shufflevectors on ARM. The initial fix was fine, but it exposed a
followup bug which I was unable to fix in a good way.

With Duncan and Nadav's input, I now attach a patch that fixes a bug
with incorrectly converting VECTOR_SHUFFLES to CONCAT_VECTORS, and a
followup of SelectionDAG::getNode() returning a TRUNCATE node to an
illegal type.

This patch has been half reviewed before and has been sitting around
without review (from Stepan) for a while, so a review would be very much
appreciated! :)

Cheers,

James
