2008-02-27Handle load/store of misaligned vectors that are the Dale Johannesen
same size as an int type by doing a bitconvert of load/store of the int type (same algorithm as floating point). This makes them work for ppc Altivec. There was some code that purported to handle loads of (some) vectors by splitting them into two smaller vectors, but getExtLoad rejects subvector loads, so this could never have worked; the patch removes it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47696 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-27LegalizeTypes support for EXTRACT_VECTOR_ELT. TheDuncan Sands
approach taken is different to that in LegalizeDAG when it is a question of expanding or promoting the result type: for example, if extracting an i64 from a <2 x i64>, when i64 needs expanding, it bitcasts the vector to <4 x i32>, extracts the appropriate two i32's, and uses those for the Lo and Hi parts. Likewise, when extracting an i16 from a <4 x i16>, and i16 needs promoting, it bitcasts the vector to <2 x i32>, extracts the appropriate i32, twiddles the bits if necessary, and uses that as the promoted value. This puts more pressure on bitcast legalization, and I've added the appropriate cases. They needed to be added anyway since users can generate such bitcasts too if they want to. Also, when considering various cases (Legal, Promote, Expand, Scalarize, Split) it is a pain that expand can correspond to Expand, Scalarize or Split, so I've changed the LegalizeTypes enum so it lists those different cases - now Expand only means splitting a scalar in two. The code produced is the same as by LegalizeDAG for all relevant testcases, except for 2007-10-31-extractelement-i64.ll, where the code seems to have improved (see below; can an expert please tell me if it is better or not).

2008-02-27LegalizeTypes support for legalizing the maskDuncan Sands
operand of a VECTOR_SHUFFLE. The mask is a vector of constant integers. The code in LegalizeDAG doesn't bother to legalize the mask, since it's basically just storage for a bunch of constants, however LegalizeTypes is more picky. The problem is that there may not exist any legal vector-of-integers type with a legal element type, so it is impossible to create a legal mask! Unless of course you cheat by creating a BUILD_VECTOR where the operands have a different type to the element type of the vector being built... This is pretty ugly but works - all relevant tests in the testsuite pass, and produce the same assembler with and without LegalizeTypes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47670 91177308-0d34-0410-b5e6-96231b3b80d8
