2012-01-20ARM vector any_extends need to be selected to vmovl. <rdar://problem/10723651>Bob Wilson
We have patterns for vector sext and zext operations but were missing anyext. Without those patterns, codegen will fail when the selection DAG has any_extend nodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148568 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-07Simplify some uses of utohexstr.Benjamin Kramer
As a side effect hex is printed lowercase instead of uppercase now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144013 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-01NEON does not support truncating vector stores. Radar 8598391.Bob Wilson
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117940 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-08Change register allocation order for ARM VFP and NEON registers to put theBob Wilson
callee-saved registers at the end of the lists. Also prefer to avoid using the low registers that are in register subclasses required by certain instructions, so that those registers will more likely be available when needed. This change makes a huge improvement in spilling in some cases. Thanks to Jakob for helping me realize the problem. Most of this patch is fixing the testsuite. There are quite a few places where we're checking for specific registers. I changed those to wildcards in places where that doesn't weaken the tests. The spill-q.ll and thumb2-spill-q.ll tests stopped spilling with this change, so I added a bunch of live values to force spills on those tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116055 91177308-0d34-0410-b5e6-96231b3b80d8

Auto-upgrade the old intrinsic and update tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112507 91177308-0d34-0410-b5e6-96231b3b80d8

zero-extend operations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111614 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-02Fix incorrect asm-printing of some NEON immediates. Fix weak testcase soBob Wilson
that it checks the immediate values, not just the instructions opcodes. Radar 8110263. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107487 91177308-0d34-0410-b5e6-96231b3b80d8

matches what llvm-gcc and clang now produce. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106221 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-06Print VMOV (immediate) operands as hexadecimal values. Apple's assemblerBob Wilson
will not accept negative values for these. LLVM's default operand printing sign extends values, so that valid unsigned values appear as negative immediates. Print all VMOV immediate operands as hex values to resolve this. Radar 7372576. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86301 91177308-0d34-0410-b5e6-96231b3b80d8

This is still a work in progress but most of the NEON instruction set is supported. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73919 91177308-0d34-0410-b5e6-96231b3b80d8
