2009-02-01Fix PR3453 and probably a bunch of other potentialDuncan Sands
crashes or wrong code with codegen of large integers: eliminate the legacy getIntegerVTBitMask and getIntegerVTSignBit methods, which returned their value as a uint64_t, so couldn't handle huge types. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63494 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-29Explain why this is here.Bill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63342 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-29- Add DebugLoc to getTargetNode(). Bill Wendling
- Modify TableGen to add the DebugLoc when calling getTargetNode. (The light-weight wrappers are only temporary. The non-DebugLoc version will be removed once the whole debug info stuff is finished with.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63273 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-29Move the code that starts printing the Select_* functionsDan Gohman
after the code that sorts the patterns. This doesn't affect the output, but it makes the code a little easier to follow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63265 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-28Add three new option properties.Mikhail Glushenkov
Adds new option properties 'multi_val', 'one_or_more' and 'zero_or_one'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63172 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-22Eliminate a couple of fields from TargetRegisterClass: SubRegClasses and ↵Evan Cheng
SuperRegClasses. These are not necessary. Also eliminate getSubRegisterRegClass and getSuperRegisterRegClass. These are slow and their results can change if register file names change. Just use TargetLowering::getRegClassFor() to get the right TargetRegisterClass instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62762 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-16Avoid triggering an assertion failure when an instruction patternDan Gohman
is a leaf node. Patch by Brandner! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62361 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-16Add support for instructions with multiple ComplexPatterns, byDan Gohman
adding more information to the temporary variables names so that they don't conflict. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62296 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-12Rename getABITypeSize to getTypePaddedSize, asDuncan Sands
suggested by Chris. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62099 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-12make tblgen autogenerate the nocapture intrinsics for Chris Lattner
llvm.memcpy/memset/memmove. This allows removal of some hackish code from basicaa. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62071 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-12add scaffolding to emit argument attributes. No functionality Chris Lattner
change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62067 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-12make tblgen emit the entire Intrinsic::getAttributes method, Chris Lattner
not a random piece of it. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62066 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-12add nocapture attribute to llvm.mem* intrinsics and have tblgenChris Lattner
parse them. tblgen doesn't yet do anything with this info though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62065 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-07Improve support for type-generic vector intrinsics by teaching TableGen howBob Wilson
to handle LLVMMatchType intrinsic parameters, and by adding new subclasses of LLVMMatchType to match vector types with integral elements that are either twice as wide or half as wide as the elements of the matched type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61834 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-19Use dyn_cast intead of isa + cast in the generated DAGISel code. ThisDan Gohman
reduces the amount of code slightly when assertions are enabled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61249 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61209 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-18Fix typo in error message.Mikhail Glushenkov
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61191 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-17Some enhancements for the 'case' expression.Mikhail Glushenkov
Add (error) and (empty). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61117 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-11Put Edge* classes into anonymous namespace.Mikhail Glushenkov
Prevents conflicts between plugins. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60871 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-07Make 'extern' an option property.Mikhail Glushenkov
Makes (forward) work better. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60667 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-07Better error message.Mikhail Glushenkov
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60664 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-07Re-apply Cedric's changes.Mikhail Glushenkov
Use B instead of Beg (for consistency), but NodeA and NodeB instead of A and B. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60663 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-07Try to guess when the auto-generated cl::Sink option should be marked 'extern'.Mikhail Glushenkov
This would be much easier to do if the CommandLine library didn't use global state. Global state is evil. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60659 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-07Add a (progn)-like construct for (actions). Implemented as a DAG list.Mikhail Glushenkov
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60658 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-07Use (actions) instead of option properties, support external options.Mikhail Glushenkov
Also includes a major refactoring. See documentation for more information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60656 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-05The use of the construct:Cedric Venet
for(Type1 B = ...;;) { Type2 B ; ... } is bad: code is hard to read and VS VS don't like it (it ignore the second declaration of B). This patch fix the problem in tablegen. Please don't write code like this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60590 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-03Rename isSimpleLoad to canFoldAsLoad, to better reflect its meaning.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60487 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-03Mark x86's V_SET0 and V_SETALLONES with isSimpleLoad, and teach X86'sDan Gohman
foldMemoryOperand how to "fold" them, by converting them into constant-pool loads. When they aren't folded, they use xorps/cmpeqd, but for example when register pressure is high, they may now be folded as memory operands, which reduces register pressure. Also, mark V_SET0 isAsCheapAsAMove so that two-address-elimination will remat it instead of copying zeros around (V_SETALLONES was already marked). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60461 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-03Add a sanity-check to tablegen to catch the case where isSimpleLoadDan Gohman
is set but mayLoad is not set. Fix all the problems this turned up. Change code to not use isSimpleLoad instead of mayLoad unless it really wants isSimpleLoad. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60459 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-28Support multiple compilation graph definitions. Not terribly useful, but ↵Mikhail Glushenkov
makes the code more generic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60199 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-28Add 'hidden' and 'really_hidden' option properties.Mikhail Glushenkov
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60198 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-27On x86 favors folding short immediate into some arithmetic operations (e.g. ↵Evan Cheng
add, and, xor, etc.) because materializing an immediate in a register is expensive in turns of code size. e.g. movl 4(%esp), %eax addl $4, %eax is 2 bytes shorter than movl $4, %eax addl 4(%esp), %eax git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60139 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-26Small fix: the error message was incorrect in some cases.Mikhail Glushenkov
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60099 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-17Support dependencies between plugins by priority-sorting.Mikhail Glushenkov
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59449 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-17Filter ToolPropertiesList to exclude all Tools not mentioned in the ↵Mikhail Glushenkov
compilation graph. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59448 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-17Add a layer of indirection to make plugins more flexible.Mikhail Glushenkov
Use strings instead of TableGen defs in the compilation graph definition. Makes it easier for the plugins to modify an existing graph. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59447 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13Fix to record comparator to make it work for return values > 1.Bill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59242 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13Put comma in correct place for call to StructType::getBill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59241 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-13Modify the intrinsics pattern to separate out the "return" types from theBill Wendling
"parameter" types. An intrinsic can now return a multiple return values like this: def add_with_overflow : Intrinsic<[llvm_i32_ty, llvm_i1_ty], [LLVMMatchType<0>, LLVMMatchType<0>]>; git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59237 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-12Check the return value of std::getenv.Mikhail Glushenkov
When constructing std::strings from C strings, we should check the input value to be not NULL so that the std::string constructor does not segfault. Fixes #3047. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59131 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-12Add a bit of lazy evaluation to PopulateCompilationGraph().Mikhail Glushenkov
Only the tools that are mentioned in the compilation graph definition are now inserted by PopulateCompilationGraph(). This should cut down plugin loading time a little. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59097 91177308-0d34-0410-b5e6-96231b3b80d8
