* Make 'extern' an option property.Mikhail Glushenkov2008-12-071-38/+19
| | | | | | Makes (forward) work better. llvm-svn: 60667
* Better error message.Mikhail Glushenkov2008-12-071-1/+6
| | | | llvm-svn: 60664
* Re-apply Cedric's changes.Mikhail Glushenkov2008-12-071-24/+24
| | | | | | | Use B instead of Beg (for consistency), but NodeA and NodeB instead of A and B. llvm-svn: 60663
* Try to guess when the auto-generated cl::Sink option should be marked 'extern'.Mikhail Glushenkov2008-12-071-5/+20
| | | | | | | This would be much easier to do if the CommandLine library didn't use global state. Global state is evil. llvm-svn: 60659
* Add a (progn)-like construct for (actions). Implemented as a DAG list.Mikhail Glushenkov2008-12-071-10/+37
| | | | llvm-svn: 60658
* Use (actions) instead of option properties, support external options.Mikhail Glushenkov2008-12-071-975/+885
| | | | | | | Also includes a major refactoring. See documentation for more information. llvm-svn: 60656
* The use of the construct:Cedric Venet2008-12-051-12/+12
| | | | | | | | 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. llvm-svn: 60590
* Rename isSimpleLoad to canFoldAsLoad, to better reflect its meaning.Dan Gohman2008-12-033-3/+3
| | | | llvm-svn: 60487
* Mark x86's V_SET0 and V_SETALLONES with isSimpleLoad, and teach X86'sDan Gohman2008-12-031-9/+0
| | | | | | | | | | | | 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). llvm-svn: 60461
* Add a sanity-check to tablegen to catch the case where isSimpleLoadDan Gohman2008-12-032-1/+10
| | | | | | | | | 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. llvm-svn: 60459

| | | | | | | | | | | | | | | 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 llvm-svn: 60139
* Small fix: the error message was incorrect in some cases.Mikhail Glushenkov2008-11-261-3/+3

* Add a layer of indirection to make plugins more flexible.Mikhail Glushenkov2008-11-171-55/+58
| | | | | | | Use strings instead of TableGen defs in the compilation graph definition. Makes it easier for the plugins to modify an existing graph. llvm-svn: 59447

* Modify the intrinsics pattern to separate out the "return" types from theBill Wendling2008-11-134-66/+170
| | | | | | | | | | "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>]>; llvm-svn: 59237
* Tell GenLibDeps.pl to inspect .so and .dylib shared files.Oscar Fuentes2008-11-121-1/+1
| | | | llvm-svn: 59158
* Check the return value of std::getenv.Mikhail Glushenkov2008-11-121-4/+8
| | | | | | | | | 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. llvm-svn: 59131
* Add a bit of lazy evaluation to PopulateCompilationGraph().Mikhail Glushenkov2008-11-121-11/+18
| | | | | | | | 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. llvm-svn: 59097

| | | | | | nodes that are already selected. llvm-svn: 58763
* Eliminate the ISel priority queue, which used the topological order for aDan Gohman2008-11-051-30/+5
| | | | | | | | | | | | | | | | | | | | | | | | priority function. Instead, just iterate over the AllNodes list, which is already in topological order. This eliminates a fair amount of bookkeeping, and speeds up the isel phase by about 15% on many testcases. The impact on most targets is that AddToISelQueue calls can be simply removed. In the x86 target, there are two additional notable changes. The rule-bending AND+SHIFT optimization in MatchAddress that creates new pre-isel nodes during isel is now a little more verbose, but more robust. Instead of either creating an invalid DAG or creating an invalid topological sort, as it has historically done, it can now just insert the new nodes into the node list at a position where they will be consistent with the topological ordering. Also, the address-matching code has logic that checked to see if a node was "already selected". However, when a node is selected, it has all its uses taken away via ReplaceAllUsesWith or equivalent, so it won't recieve any further visits from MatchAddress. This code is now removed. llvm-svn: 58748
* Give tablegen's Type a destructor, to suppress spuriousDan Gohman2008-11-041-0/+1
| | | | | | | "Type has virtual functions but non-virtual destructor" warnings. llvm-svn: 58710
* Add some asserts to verify MVT invariant assumptions.Dan Gohman2008-11-041-0/+2
| | | | llvm-svn: 58701
* Change how extended types are represented in MVTs. Instead of fiddlingDan Gohman2008-11-032-0/+124
| | | | | | | | | | | | | | | | | | | | | | | | bits, use a union of a SimpleValueType enum and a regular Type*. This increases the size of MVT on 64-bit hosts from 32 bits to 64 bits. In most cases, this doesn't add significant overhead. There are places in codegen that use arrays of MVTs, so these are now larger, but they're small in common cases. This eliminates restrictions on the size of integer types and vector types that can be represented in codegen. As the included testcase demonstrates, it's now possible to codegen very large add operations. There are still some complications with using very large types. PR2880 is still open so they can't be used as return values on normal targets, there are no libcalls defined for very large integers so operations like multiply and divide aren't supported. This also introduces a minimal tablgen Type library, capable of handling IntegerType and VectorType. This will allow parts of TableGen that don't depend on using SimpleValueType values to handle arbitrary integer and vector types. llvm-svn: 58623

* - Fix SUBVERSION string to handle x.x.x version number formats.Bill Wendling2008-10-271-3/+6
| | | | | | | | - Add VERBOSE=1 flag. - Specify the LLVM_SUBMIT_VERSION when doing the "make install". The libLTO.dylib relies upon this flag during that time. llvm-svn: 58298
* Have TableGen emit setSubgraphColor calls under control of a -gen-debugDavid Greene2008-10-271-5/+45
| | | | | | | | flag. Then in a debugger developers can set breakpoints at these calls to see waht is about to be selected and what the resulting subgraph looks like. This really helps when debugging instruction selection. llvm-svn: 58278

* Use INT64_C to emit constant values, to avoid problems withDan Gohman2008-10-171-2/+3
| | | | | | | | constants that don't fit in an int. This fixes "this decimal constant is unsigned only in ISO C90" warnings. llvm-svn: 57668
* Fun x86 encoding tricks: when adding an immediate value of 128,Dan Gohman2008-10-177-27/+40
| | | | | | | | | | | | | use a SUB instruction instead of an ADD, because -128 can be encoded in an 8-bit signed immediate field, while +128 can't be. This avoids the need for a 32-bit immediate field in this case. A similar optimization applies to 64-bit adds with 0x80000000, with the 32-bit signed immediate field. To support this, teach tablegen how to handle 64-bit constants. llvm-svn: 57663
* Add support for having multiple predicates on a TreePatternNode.Dan Gohman2008-10-154-70/+109
| | | | | | | | This will allow predicates to be composed, which will allow the predicate definitions to become less redundant, and eventually will allow DAGISelEmitter.cpp to emit less redundant code. llvm-svn: 57562
