2006-06-15Consistency. EXTRACT_ELEMENT index operand should have ptr type.Evan Cheng

2006-06-15Instructions with variable operands (variable_ops) can have a number requiredEvan Cheng
operands. e.g. def CALL32r : I<0xFF, MRM2r, (ops GR32:$dst, variable_ops), "call {*}$dst", [(X86call GR32:$dst)]>; TableGen should emit operand informations for the "required" operands. Added a target instruction info flag M_VARIABLE_OPS to indicate the target instruction may have more operands in addition to the minimum required operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28791 91177308-0d34-0410-b5e6-96231b3b80d8
2006-06-14X86 call instructions can take variable number of operands. Parameters ofEvan Cheng

LCSSA is still the slowest pass when gccas'ing 252.eon, but now it only takes 39s instead of 289s. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28776 91177308-0d34-0410-b5e6-96231b3b80d8

2006-06-13Fix a bug that was causing major slowdowns in povray. This was due to LCSSAOwen Anderson
not handling PHI nodes correctly when determining if a value was live-out. This patch reduces the number of detected live-out variables in the testcase from 6565 to 485. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28771 91177308-0d34-0410-b5e6-96231b3b80d8

2006-06-12Fix for 2006-06-26-MultipleExitsSingleBlock.Owen Anderson
If a single exit block has multiple predecessors within the loop, it will appear in the exit blocks list more than once. LCSSA needs to take that into account so that it doesn't double process that exit block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28750 91177308-0d34-0410-b5e6-96231b3b80d8

2006-06-10Fix a problem exposed by the local allocator. CALL instructions are not markedChris Lattner
as using incoming argument registers, so the local allocator would clobber them between their set and use. To fix this, we give the call instructions a variable number of uses in the CALL MachineInstr itself, so live variables understands the live ranges of these register arguments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28744 91177308-0d34-0410-b5e6-96231b3b80d8

2006-06-09RewriteExpr, either the new PHI node of induction variable or theEvan Cheng
