2009-01-04Use softtabstop instead of redefining tabstop.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61618 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-04Switch the vimrc file from smartindent to cindent, which isDan Gohman
smarter about C-ish syntax, and supports the cinoptions variable. Set cinoptions to suppress the extra indentation for switch case labels. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61617 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-02vimrcMisha Brukman
* Fixed cursors in terminal by setting nocompatible (sorry, vi users) * Enable syntax highlighting so that this file can stand on its own * Highlight trailing whitespace * Fixed commands to delete trailing whitespaces and convert tabs to spaces llvm.vim and tablegen.vim * Removed trailing whitespace, as it's now very visible git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61582 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-02We also removed gtest-all.cc from the distribution tarball.Misha Brukman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61581 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-01Original patch by Talin.Misha Brukman
* Added the first LLVM unittest -- DenseMap. * Updated mkpatch utility to include llvm/unittests dir * Added top-level target "unittests" to run all unittests git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61541 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-01* Removed gtest-all.cc; .cc files including other .cc files is weirdMisha Brukman
* Removed gtest_main.cc: we have our own main() elsewhere * Simplified the Makefile as we don't need SOURCES * Moved the internal header to gtest/internal/ * Simplified the Makefile to remove -I param to CPP.Flags * Updated README.LLVM with all the steps I took to massage GTest to work in LLVM so far git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61540 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-01Moved Google Test code up one directory so that we can use a standard LLVMMisha Brukman
Makefile with it, without resorting to the use of VPATH. Also added Makefiles at every level of the directory tree to properly recurse to Google Test and build it as a library (original Makefiles by Talin). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61539 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-31Import of Google Test 1.2.1, with the non-essential bits removed.Misha Brukman
Added a README.LLVM file to indicate which files and directories were removed from the original source tarball. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61526 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

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
2008-12-16Change so that buildit won't need a parent directory with only the build ↵Bill Wendling
scripts in them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61061 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

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

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

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59242 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

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59158 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

2008-11-08Properly escape dashes in TableGen's LLVMC2 emitter.Anton Korobeynikov
Patch by Patrick Walton! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58901 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-07Make tablegen print out a nice error message for a const char*Dan Gohman
exception, like it does for a std::string exception. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58865 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-05Use an assert to check that SelectCode isn't called onDan Gohman
nodes that are already selected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58763 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-05Eliminate the ISel priority queue, which used the topological order for aDan Gohman
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58748 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-04Give tablegen's Type a destructor, to suppress spuriousDan Gohman
"Type has virtual functions but non-virtual destructor" warnings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58710 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-04Add some asserts to verify MVT invariant assumptions.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58701 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-03Change how extended types are represented in MVTs. Instead of fiddlingDan Gohman
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58623 91177308-0d34-0410-b5e6-96231b3b80d8
