This is the final patch for this PR. It implements some minor cleanup in the use of IntegerType, to wit: 1. Type::getIntegerTypeMask -> IntegerType::getBitMask 2. Type::Int*Ty changed to IntegerType* from Type* 3. ConstantInt::getType() returns IntegerType* now, not Type* This also fixes PR1120.

Take an incremental step towards type plane elimination. This change separates types from values in the symbol tables by finally making use of the TypeSymbolTable class. This yields more natural interfaces for dealing with types and unclutters the SymbolTable class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32956 91177308-0d34-0410-b5e6-96231b3b80d8

Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting fall out by removing unused variables.

2006-09-23Be far more careful when splitting a loop header, either to form a preheaderChris Lattner
or when splitting loops with a common header into multiple loops. In particular the old code would always insert the preheader before the old loop header. This is disasterous in cases where the loop hasn't been rotated. For example, it can produce code like: .. outside the loop... jmp LBB1_2 #bb13.outer LBB1_1: #bb1 movsd 8(%esp,%esi,8), %xmm1 mulsd (%edi), %xmm1 addsd %xmm0, %xmm1 addl $24, %edi incl %esi jmp LBB1_3 #bb13 LBB1_2: #bb13.outer leal (%edx,%eax,8), %edi pxor %xmm1, %xmm1 xorl %esi, %esi LBB1_3: #bb13 movapd %xmm1, %xmm0 cmpl $4, %esi jl LBB1_1 #bb1 Note that the loop body is actually LBB1_1 + LBB1_3, which means that the loop now contains an uncond branch WITHIN it to jump around the inserted loop header (LBB1_2). Doh. This patch changes the preheader insertion code to insert it in the right spot, producing this code: ... outside the loop, fall into the header ... LBB1_1: #bb13.outer leal (%edx,%eax,8), %esi pxor %xmm0, %xmm0 xorl %edi, %edi jmp LBB1_3 #bb13 LBB1_2: #bb1 movsd 8(%esp,%edi,8), %xmm0 mulsd (%esi), %xmm0 addsd %xmm1, %xmm0 addl $24, %esi incl %edi LBB1_3: #bb13 movapd %xmm0, %xmm1 cmpl $4, %edi jl LBB1_2 #bb1 Totally crazy, no branch in the loop! :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30587 91177308-0d34-0410-b5e6-96231b3b80d8

2006-08-12Reimplement the loopsimplify code which deletes edges from unreachableChris Lattner
blocks that target loop blocks. Before, the code was run once per loop, and depended on the number of predecessors each block in the loop had. Unfortunately, scanning preds can be really slow when huge numbers of phis exist or when phis with huge numbers of inputs exist. Now, the code is run once per function and scans successors instead of preds, which is far faster. In addition, the new code is simpler and is goto free, woo. This change speeds up a nasty testcase Duraid provided me from taking hours to taking ~72s with a debug build. The functionality this implements is already tested in the testsuite as Transforms/CodeExtractor/2004-03-13-LoopExtractorCrash.ll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29644 91177308-0d34-0410-b5e6-96231b3b80d8
