* Fixes the last x86-64 test failure in compat.exp:Dale Johannesen2008-06-26
| | | | | | | | | | | | | | | <16 x float> is 64-byte aligned (for some reason), which gets us into the stack realignment code. The computation changing FP-relative offsets to SP-relative was broken, assiging a spill temp to a location also used for parameter passing. This fixes it by rounding up the stack frame to a multiple of the largest alignment (I concluded it wasn't fixable without doing this, but I'm not very sure.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52750 91177308-0d34-0410-b5e6-96231b3b80d8

* Wrap MVT::ValueType in a struct to get type safetyDuncan Sands2008-06-06
| | | | | | | | | | | | | | | | | and better control the abstraction. Rename the type to MVT. To update out-of-tree patches, the main thing to do is to rename MVT::ValueType to MVT, and rewrite expressions like MVT::getSizeInBits(VT) in the form VT.getSizeInBits(). Use VT.getSimpleVT() to extract a MVT::SimpleValueType for use in switch statements (you will get an assert failure if VT is an extended value type - these shouldn't exist after type legalization). This results in a small speedup of codegen and no new testsuite failures (x86-64 linux). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52044 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix the position of MemOperands in nodes that use variadic_opsDan Gohman2008-06-02
| | | | | | | | | | | | | in DAGISelEmitter output. This bug was recently uncovered by the addition of patterns for CALL32m and CALL64m, which are nodes that now have both MemOperands and variadic_ops. This bug was especially visible with PIC in various configurations, because the new patterns are matching the indirect call code used in many PIC configurations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51877 91177308-0d34-0410-b5e6-96231b3b80d8

Instead keep track of how many fixed operands the input pattern actually has, and have the input matching code pass the output-emitting function that index value. This simplifies the code, disentangles variables_ops from the support for predication operations, and makes variable_ops more robust. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51808 91177308-0d34-0410-b5e6-96231b3b80d8

* New feature: OptionList.Mikhail Glushenkov2008-05-30
| | | | | | | | | | | | | | | | | | | It can be handy to have all information about options gathered in a single place to provide an overview of all supported options. This patch allows the following: def Options : OptionList<[ (switch_option "E", (help "Help string")), (alias_option "quiet", "q") ... ]>; Tool-specific option properties (like 'append_cmd') have (obviously) no meaning in this context, so the only properties that are allowed are 'help' and 'required'. See usage example in examples/Clang.td. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51754 91177308-0d34-0410-b5e6-96231b3b80d8

This adds a new construct, "discard", for indicating that a named node in the input matching pattern is to be discarded, instead of corresponding to a node in the output pattern. This allows tblgen to know where the arguments for the varaible_ops are supposed to begin.
