2010-04-20teach cellspu how to return i8 and i16 from calls,Chris Lattner
patch by Kalle Raiskila! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101875 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20remove a bunch of ad-hoc code to simplify instructions fromChris Lattner
loop unswitch, and use inst simplify instead. It is more powerful and less duplication. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101874 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20move some select simplifications out out instcombine intoChris Lattner
inst simplify. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101873 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20RewriteLoopBodyWithConditionConstant can end up rewriting theChris Lattner
condition we're unswitching on. In this case, don't try to simplify the second copy of the loop which may be dead or not, but is probably a constant now. This fixes PR6879 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101870 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20reapply 'reject forward references to functions whose type don't match'Chris Lattner
now that the testsuite has been updated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101866 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20Delete a redundant return statement.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101860 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20The visitXOR method can return the same SDNode. If so, we don't want to deleteBill Wendling
it as it's not dead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101855 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20disable optimizations in this directory for MSVC9. This avoidsChris Lattner
an optimizer infinite loop on the file, PR6866. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101854 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20Better error-handling for DisassembleThumb2DPModImm() with 2-reg operands whereJohnny Chen
d==15 is considered illegal. Return false instead of assert(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101852 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20Remove the palignr intrinsics now that we lower them to vector shuffles,Eric Christopher
shifts and null vectors. Autoupgrade these to what we'd lower them to. Add a testcase to exercise this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101851 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20Remove this debug output; it isn't that useful, and it's incompleteDan Gohman
in the case where a basic block is split. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101850 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20Sink DebugLoc handling out of SelectionDAGISel into FastISel andDan Gohman
SelectionDAGBuilder, where it doesn't have to be as complicated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101848 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20make CallGraphNode dtor abort if a node is deleted when there are stillChris Lattner
references to it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101847 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20make the inliner do less work for leaf functions.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101846 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20Fix rdar://7879828 - crash in CallGraph, a self host issue.Chris Lattner
Arg promotion was deleting call graph nodes that still had references from the 'indirect' CGN. Like the inliner, it should only delete the function if all references are gone. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101845 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20Remove MachineFunction's DefaultDebugLoc member, and make DwarfDebug.cppDan Gohman
responsible for figuring out what that's supposed to be on its own. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101844 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20Reapply the removal of SelectionDAGISel's BB, with a fix for the caseDan Gohman
where multiple blocks are emitted; functions which do this need to return the new BB so that their callers can stay current. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101843 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20Fix tests for Neon load/store intrinsics to match the i8* types expected byBob Wilson
the intrinsics. The reason for those i8* types is that the intrinsics are overloaded on the vector type and we don't have a way to declare an intrinsic where one argument is an overloaded vector type and another argument is a pointer to the vector element type. The bitcasts added here will match what the frontend will typically generate when these intrinsics are used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101840 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20More IT instruction error-handling improvements from fuzzing.Johnny Chen
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101839 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-19Revert 101825, which is causing trouble.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101832 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-19Make BreakAntiDependencies' SUnits argument const, and make the BeginDan Gohman
and End arguments by-value rather than by-reference. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101830 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-19Better error handling of invalid IT mask '0000', instead of just asserting.Johnny Chen
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101827 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-19Eliminate SelectionDAGISel's "current block" member. Just pass it asDan Gohman
an argument to things that need it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101825 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-19Delete an unnecessary reference to SelectionDAGISel::BB.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101824 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-19Eliminate the CurMBB member from SelectionDAGBuilder. For places thatDan Gohman
need it, just pass around the parent block of the current instruction explicitly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101822 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-19Remove the Expr member from IVUsers. Instead of remembering the expression,Dan Gohman
just ask ScalarEvolution for it on demand. This helps IVUsers be more robust in the case of expressions changing underneath it. This fixes PR6862. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101819 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-19According to A8.6.16 B (Encoding T3) and A8.3 Conditional execution -- A8.3.1Johnny Chen
Pseudocode details of conditional, Condition bits '111x' indicate the instruction is always executed. That is, '1111' is a leagl condition field value, which is now mapped to ARMCC::AL. Also add a test case for condition field '1111'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101817 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-19Give SelectionDAG a TargetMachine too, rather than having itDan Gohman
fetch one from the MachineFunction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101807 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-19Code that needs a TargetMachine should have access to one directly, ratherDan Gohman
than just getting one through a TargetLowering. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101802 91177308-0d34-0410-b5e6-96231b3b80d8

SelectionDAG-specific. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101801 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-19Enable -Wcast-qual for C++ files, where intentional qualifier-stripping canDan Gohman
be done with const_cast. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101798 91177308-0d34-0410-b5e6-96231b3b80d8
