* One mundane change: Change ReplaceAllUsesOfValueWith to *optionally* Chris Lattner2007-10-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | take a deleted nodes vector, instead of requiring it. One more significant change: Implement the start of a legalizer that just works on types. This legalizer is designed to run before the operation legalizer and ensure just that the input dag is transformed into an output dag whose operand and result types are all legal, even if the operations on those types are not. This design/impl has the following advantages: 1. When finished, this will *significantly* reduce the amount of code in LegalizeDAG.cpp. It will remove all the code related to promotion and expansion as well as splitting and scalarizing vectors. 2. The new code is very simple, idiomatic, and modular: unlike LegalizeDAG.cpp, it has no 3000 line long functions. :) 3. The implementation is completely iterative instead of recursive, good for hacking on large dags without blowing out your stack. 4. The implementation updates nodes in place when possible instead of deallocating and reallocating the entire graph that points to some mutated node. 5. The code nicely separates out handling of operations with invalid results from operations with invalid operands, making some cases simpler and easier to understand. 6. The new -debug-only=legalize-types option is very very handy :), allowing you to easily understand what legalize types is doing. This is not yet done. Until the ifdef added to SelectionDAGISel.cpp is enabled, this does nothing. However, this code is sufficient to legalize all of the code in 186.crafty, olden and freebench on an x86 machine. The biggest issues are: 1. Vectors aren't implemented at all yet 2. SoftFP is a mess, I need to talk to Evan about it. 3. No lowering to libcalls is implemented yet. 4. Various operations are missing etc. 5. There are FIXME's for stuff I hax0r'd out, like softfp. Hey, at least it is a step in the right direction :). If you'd like to help, just enable the #ifdef in SelectionDAGISel.cpp and compile code with it. If this explodes it will tell you what needs to be implemented. Help is certainly appreciated. Once this goes in, we can do three things: 1. Add a new pass of dag combine between the "type legalizer" and "operation legalizer" passes. This will let us catch some long-standing isel issues that we miss because operation legalization often obfuscates the dag with target-specific nodes. 2. We can rip out all of the type legalization code from LegalizeDAG.cpp, making it much smaller and simpler. When that happens we can then reimplement the core functionality left in it in a much more efficient and non-recursive way. 3. Once the whole legalizer is non-recursive, we can implement whole-function selectiondags maybe... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42981 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | LLVM. It cleans up the intrinsic definitions and generally smooths the process for more complicated intrinsic writing. It will be used by the upcoming atomic intrinsics as well as vector and float intrinsics in the future. This also changes the syntax for llvm.bswap, llvm.part.set, llvm.part.select, and llvm.ct* intrinsics. They are automatically upgraded by both the LLVM ASM reader and the bitcode reader. The test cases have been updated, with special tests added to ensure the automatic upgrading is supported. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40807 91177308-0d34-0410-b5e6-96231b3b80d8

* VStudio compiler errors and placing Function*->ExFunc map under ↵Chuck Rose III2007-07-271-2/+2
| | | | | | | | | | | | | ManagedStatic control. This commit fixes two things. One is a pair of VStudio compiler errors stemming from variables which defined within the for loop statement and also within the body of the for loop. I fixed these by renaming one of the two variables. Additionally, I've made the Function*->ExFunc map in ExternalFunctions.cpp a ManagedStatic object, so that cleanup will be done on llvm_shutdown. In repeated uses of the interpreter, where the same Function* address may get used for completely differnet functions, this was causing a crash. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40558 91177308-0d34-0410-b5e6-96231b3b80d8
