| | | | | | | | | | | Instruction::isSameOperationAs. Maintaining this kind of checking in different places is dangerous, extending Instruction::isSameOperationAs consolidates this logic into one place. Here I've added an optional flags parameter and two flags that are important for vectorization: CompareIgnoringAlignment and CompareUsingScalarTypes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159329 91177308-0d34-0410-b5e6-96231b3b80d8
* Now that Reassociate's LinearizeExprTree can look through arbitrary expressionDuncan Sands2012-06-12
| | | | | | | | | | | | | | | | | | topologies, it is quite possible for a leaf node to have huge multiplicity, for example: x0 = x*x, x1 = x0*x0, x2 = x1*x1, ... rapidly gives a value which is x raised to a vast power (the multiplicity, or weight, of x). This patch fixes the computation of weights by correctly computing them no matter how big they are, rather than just overflowing and getting a wrong value. It turns out that the weight for a value never needs more bits to represent than the value itself, so it is enough to represent weights as APInts of the same bitwidth and do the right overflow-avoiding dance steps when computing weights. As a side-effect it reduces the number of multiplies needed in some cases of large powers. While there, in view of external uses (eg by the vectorizer) I made LinearizeExprTree static, pushing the rank computation out into users. This is progress towards fixing PR13021. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158358 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix a major source of compile-time slowness at -O0 -g by optimizingChris Lattner2010-03-30
| | | | | | | | | | | | | | | the storage of !dbg metadata kinds in the instruction themselves. The on-the-side hash table works great for metadata that not-all instructions get, or for metadata that only exists when optimizing. But when compile-time is everything, it isn't great. I'm not super thrilled with the fact that this plops a TrackingVH in Instruction, because it grows it by 3 words. I'm investigating alternatives, but this should be a step in the right direction in any case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99957 91177308-0d34-0410-b5e6-96231b3b80d8

* This is a major cleanup of the instruction metadata interfaces thatChris Lattner2009-12-28
| | | | | | | | | | | | | | | | | | | | | | | I asked Devang to do back on Sep 27. Instead of going through the MetadataContext class with methods like getMD() and getMDs(), just ask the instruction directly for its metadata with getMetadata() and getAllMetadata(). This includes a variety of other fixes and improvements: previously all Value*'s were bloated because the HasMetadata bit was thrown into value, adding a 9th bit to a byte. Now this is properly sunk down to the Instruction class (the only place where it makes sense) and it will be folded away somewhere soon. This also fixes some confusion in getMDs and its clients about whether the returned list is indexed by the MDID or densely packed. This is now returned sorted and densely packed and the comments make this clear. This introduces a number of fixme's which I'll follow up on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92235 91177308-0d34-0410-b5e6-96231b3b80d8

* Rename Instruction::isIdenticalTo to Instruction::isIdenticalToWhenDefined,Dan Gohman2009-08-25
| | | | | | | | | | | | | | | | | and introduce a new Instruction::isIdenticalTo which tests for full identity, including the SubclassOptionalData flags. Also, fix the Instruction::clone implementations to preserve the SubclassOptionalData flags. Finally, teach several optimizations how to handle SubclassOptionalData correctly, given these changes. This fixes the counterintuitive behavior of isIdenticalTo not comparing the full value, and clone not returning an identical clone, as well as some subtle bugs that could be caused by these. Thanks to Nick Lewycky for reporting this, and for an initial patch! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80038 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | function with a new NumLowBitsAvailable enum, which makes the value available as an integer constant expression. Add PointerLikeTypeTraits specializations for Instruction* and Use** since they are only guaranteed 4-byte aligned. Enhance PointerIntPair to know about (and enforce) the alignment specified by PointerLikeTypeTraits. This should allow things like PointerIntPair<PointerIntPair<void*, 1,bool>, 1, bool> because the inner one knows that 2 low bits are free. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67979 91177308-0d34-0410-b5e6-96231b3b80d8

* Switch the asmprinter (.ll) and all the stuff it requires over toChris Lattner2008-08-23
| | | | | | | | | | | | | | | | | | | | | | | | | | use raw_ostream instead of std::ostream. Among other goodness, this speeds up llvm-dis of kc++ with a release build from 0.85s to 0.49s (88% faster). Other interesting changes: 1) This makes Value::print be non-virtual. 2) AP[S]Int and ConstantRange can no longer print to ostream directly, use raw_ostream instead. 3) This fixes a bug in raw_os_ostream where it didn't flush itself when destroyed. 4) This adds a new SDNode::print method, instead of only allowing "dump". A lot of APIs have both std::ostream and raw_ostream versions, it would be useful to go through and systematically anihilate the std::ostream versions. This passes dejagnu, but there may be minor fallout, plz let me know if so and I'll fix it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55263 91177308-0d34-0410-b5e6-96231b3b80d8
* Fold the useful features of alist and alist_node into ilist, andDan Gohman2008-07-28
| | | | | | | | | | | | | | | | | a new ilist_node class, and remove them. Unlike alist_node, ilist_node doesn't attempt to manage storage itself, so it avoids the associated problems, including being opaque in gdb. Adjust the Recycler class so that it doesn't depend on alist_node. Also, change it to use explicit Size and Align parameters, allowing it to work when the largest-sized node doesn't have the greatest alignment requirement. Change MachineInstr's MachineMemOperand list from a pool-backed alist to a std::list for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54146 91177308-0d34-0410-b5e6-96231b3b80d8
