Fix pr3571: If stride is a value defined by an instruction, make sure it dominates the loop preheader. When IV users are strength reduced, the stride is inserted into the preheader. It could create a use before def situation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_25@64789 91177308-0d34-0410-b5e6-96231b3b80d8

Make a transformation added in 63266 a bit less aggressive. It was transforming (x&y)==y to (x&y)!=0 in the case where y is variable and known to have at most one bit set (e.g. z&1). This is not correct; the expressions are not equivalent when y==0. I believe this patch salvages what can be salvaged, including all the cases in bt.ll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_25@64782 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-31Reinstate this optimization to fold icmp of xor when possible. Don't try toNick Lewycky

2009-01-31Fix PR3452 (an infinite loop bootstrapping) by disabling the recentChris Lattner
improvements to the EvaluateInDifferentType code. This code works by just inserted a bunch of new code and then seeing if it is useful. Instcombine is not allowed to do this: it can only insert new code if it is useful, and only when it is converging to a more canonical fixed point. Now that we iterate when DCE makes progress, this causes an infinite loop when the code ends up not being used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63483 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-31Fix PR3401: when using large integers, the typeDuncan Sands
returned by getShiftAmountTy may be too small to hold shift values (it is an i8 on x86-32). Before and during type legalization, use a large but legal type for shift amounts: getPointerTy; afterwards use getShiftAmountTy, fixing up any shift amounts with a big type during operation legalization. Thanks to Dan for writing the original patch (which I shamelessly pillaged). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63482 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-31now that all the pieces are in place, teach instcombine'sChris Lattner
simplifydemandedbits to simplify instructions with *multiple uses* in contexts where it can get away with it. This allows it to simplify the code in multi-use-or.ll into a single 'add double'. This change is particularly interesting because it will cover up for some common codegen bugs with large integers created due to the recent SROA patch. When working on fixing those bugs, this should be disabled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63481 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-31Simplify and generalize the SROA "convert to scalar" transformation toChris Lattner
be able to handle *ANY* alloca that is poked by loads and stores of bitcasts and GEPs with constant offsets. Before the code had a number of annoying limitations and caused it to miss cases such as storing into holes in structs and complex casts (as in bitfield-sroa) where we had unions of bitfields etc. This also handles a number of important cases that are exposed due to the ABI lowering stuff we do to pass stuff by value. One case that is pretty great is that we compile 2006-11-07-InvalidArrayPromote.ll into: define i32 @func(<4 x float> %v0, <4 x float> %v1) nounwind { %tmp10 = call <4 x i32> @llvm.x86.sse2.cvttps2dq(<4 x float> %v1) %tmp105 = bitcast <4 x i32> %tmp10 to i128 %tmp1056 = zext i128 %tmp105 to i256 %tmp.upgrd.43 = lshr i256 %tmp1056, 96 %tmp.upgrd.44 = trunc i256 %tmp.upgrd.43 to i32 ret i32 %tmp.upgrd.44 } which turns into: _func: subl $28, %esp cvttps2dq %xmm1, %xmm0 movaps %xmm0, (%esp) movl 12(%esp), %eax addl $28, %esp ret Which is pretty good code all things considering :). One effect of this is that SROA will start generating arbitrary bitwidth integers that are a multiple of 8 bits. In the case above, we got a 256 bit integer, but the codegen guys assure me that it can handle the simple and/or/shift/zext stuff that we're doing on these operations. This addresses rdar://6532315 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63469 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-30 Each input file is encoded as a separate compile unit in LLVM debuggingDevang Patel
information output. However, many target specific tool chains prefer to encode only one compile unit in an object file. In this situation, the LLVM code generator will include debugging information entities in the compile unit that is marked as main compile unit. The code generator accepts maximum one main compile unit per module. If a module does not contain any main compile unit then the code generator will emit multiple compile units in the output object file. [Part 1] Update DebugInfo APIs to accept optional boolean value while creating DICompileUnit to mark the unit as "main" unit. By defaults all units are considered non-main. Update SourceLevelDebugging.html to document "main" compile unit. Update DebugInfo APIs to not accept and encode separate source file/directory entries while creating various llvm.dbg.* entities. There was a recent, yet to be documented, change to include this additional information so no documentation changes are required here. Update DwarfDebug to handle "main" compile unit. If "main" compile unit is seen then all DIEs are inserted into "main" compile unit. All other compile units are used to find source location for llvm.dbg.* values. If there is not any "main" compile unit then create unique compile unit DIEs for each llvm.dbg.compile_unit. [Part 2] Create separate llvm.dbg.compile_unit for each input file. Mark compile unit create for main_input_filename as "main" compile unit. Use appropriate compile unit, based on source location information collected from the tree node, while creating llvm.dbg.* values using DebugInfo APIs. --- This is Part 1. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63400 91177308-0d34-0410-b5e6-96231b3b80d8
