2009-10-28Previously, all operands to Constant were themselves constant.Chris Lattner
In the new world order, BlockAddress can have a BasicBlock operand. This doesn't permute much, because if you have a ConstantExpr (or anything more specific than Constant) we still know the operand has to be a Constant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85375 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-28'static const void *X = &&y' can only be put in the Chris Lattner
readonly section if a reference to the containing function is valid in the readonly section. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85370 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-28Rewrite SelectionDAG::isPredecessorOf to be iterative instead ofDan Gohman
recursive to avoid consuming extraordinary amounts of stack space when processing tall graphs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85369 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-28full asmparser support for blockaddress. We can now do:Chris Lattner
$ llvm-as foo.ll -d -disable-output which reads and prints the .ll file. BC encoding is the next project. Testcase will go in once that works. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85368 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-28when we tear down a module, we need to be careful to Chris Lattner

2009-10-28Teach MachineLICM to unfold loads from constant memory fromDan Gohman
otherwise unhoistable instructions in order to allow the loads to be hoisted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85364 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-28Mark dead physregdefs dead immediately. This helps MachineSink andDan Gohman
MachineLICM and other things which run before LiveVariables is run. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85360 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-28Allow constants of different types to share constant pool entriesDan Gohman
if they have compatible encodings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85359 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-28Remove getIEEEFloatParts and getIEEEDoubleParts. They are not needed.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85358 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-28Update SystemZ to use PSW following the way x86 uses EFLAGS. BesidesDan Gohman
eliminating a use of MVT::Flag, this is needed for an upcoming CodeGen change. This unfortunately requires SystemZ to switch to the list-burr scheduler, in order to handle the physreg defs properly, however that's what LLVM has available at this time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85357 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-28IR support for the new BlockAddress constant kind. This isChris Lattner
untested and there is no way to use it, next up: doing battle with asmparser. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85349 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-27Record CodeGen optimization level in the BranchFolding pass so that we canBob Wilson
use it to control tail merging when there is a tradeoff between performance and code size. When there is only 1 instruction in the common tail, we have been merging. That can be good for code size but is a definite loss for performance. Now we will avoid tail merging in that case when the optimization level is "Aggressive", i.e., "-O3". Radar 7338114. Since the IfConversion pass invokes BranchFolding, it too needs to know the optimization level. Note that I removed the RegisterPass instantiation for IfConversion because it required a default constructor. If someone wants to keep that for some reason, we can add a default constructor with a hard-wired optimization level. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85346 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-27Rename lib/VMCore/ConstantsContext.h:ValueMap<> to ConstantUniqueMap<> to avoidJeffrey Yasskin
