David Goodwin 5285817490 When possible, use "mvn ra, rb" instead of "eor ra, rb, -1" because mvn has a narrow version and eor(i) does not.

Dan Gohman d3b930d426 Add some testcases for some of the recent ScalarEvolution bug fixes. 
llvm-svn: 74353
 2009-06-26 22:54:11 +00:00
Dan Gohman daafbe6168 Incorporate the insertion point into the key of SCEVExpander's CSE map. 
This helps it avoid reusing an instruction that doesn't dominate all
of the users, in cases where the original instruction was inserted
before all of the users were known.  This may result in redundant
expansions of sub-expressions that depend on loop-unpredictable values
in some cases, however this isn't very common, and it primarily impacts
IndVarSimplify, so GVN can be expected to clean these up.

This eliminates the need for IndVarSimplify's FixUsesBeforeDefs,
which fixes several bugs.

Dan Gohman cc030b7e51 Fix ScalarEvolution::getAddRecExpr's code which canonicalized the 
nesting order of nested AddRec expressions to skip the transformation
if it would introduce an AddRec with operands not loop-invariant
with respect to its loop.

Daniel Dunbar 2d83134ca6 NewNightlyTest.pl: Support -submit-aux with -no-submit (run that aux script,

Chris Lattner 40bc649ce9 add %rip to the GR64 register class. Lets avoid allocating it to anything though! :)

Chris Lattner 899abc4655 make sure to propagate operand flags in SelectTLSADDRAddr properly. 
llvm-svn: 74326
 2009-06-26 21:18:37 +00:00
Chris Lattner bc60c14c97 fix a really subtle bug in the cross section of aliases and TLS: 
the SelectionDAG::getGlobalAddress function properly looks through
aliases to determine thread-localness, but then passes the GV* down
to GlobalAddressSDNode::GlobalAddressSDNode which does not.  Instead
of passing down isTarget, just pass down the predetermined node
opcode.  This fixes some assertions with out of tree changes I'm 
working on.

 2009-06-26 16:20:06 +00:00
David Goodwin 0377f737ff Currently there is a pattern for the thumb-2 MOV 16-bit immediate instruction. That instruction cannot write the flags so it should use T2I instead of T2sI. 
Also, added a pattern for the thumb-2 MOV of shifted immediate since that can encode immediates not encodable by the 16-bit immediate.
