2011-07-29[AVX] Make CodeInit UniqueDavid Greene
Use a StringMap to ensure CodeInits are unique and created only once. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136492 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29[AVX] Make StringInit UniqueDavid Greene
Use a StringMap to ensure the StringInits are unique. This is especially important for AVX where we will have many smallish strings representing instruction prefixes, suffixes and the like. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136491 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29[AVX] Make IntInit UniqueDavid Greene
Use a DenseMap to make sure only one IntInit of any value exists. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136490 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29[AVX] Make BitsInit UniqueDavid Greene
Make BitsInit a FoldingSetNode so we can unique it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136489 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29[AVX] Unique BitInitDavid Greene
Keep only two copies of BitInit: one for true and one for false. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136488 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29[AVX] Unique UnsetInitDavid Greene
Keep only one UnsetInit around. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136487 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29[AVX] Create Inits Via Factory MethodDavid Greene
Replace uses of new *Init with *Init::get. This hides the allocation implementation so that we can unique Inits in various ways. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136486 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29[AVX] Constify InitsDavid Greene
Make references to Inits const everywhere. This is the final step before making them unique. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136485 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29[AVX] Remove non-const IteratorsDavid Greene
Remove all non-const iterators from Init classes. This is another step toward constifying Inits and ultimately turning them into FoldingSetNodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136484 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29[AVX] Remove Mutating Members from InitsDavid Greene
Get rid of all Init members that modify internal state. This is in preparation for making references to Inits const. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136483 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29Add ListInit::getValuesDavid Greene
Add a getValues ListInit method to return the sequence of values in the list. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136482 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29Add a std::string Wrapper for TableGenDavid Greene
Create a std::string wrapper for use as a DenseMap key. DenseMap is not safe in generate with strings, so this wrapper indicates that only strings guaranteed not to have certain values should be used in the DenseMap. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136481 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136480 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29ARM assembly parsing and encoding for RFE instruction.Jim Grosbach
Fill in the missing fixed bits and the register operand bits of the instruction encoding. Refactor the definition to make the mode explicit, which is consistent with how loads and stores are normally represented and makes parsing much easier. Add parsing aliases for pseudo-instruction variants. Update the disassembler for the new representations. Add tests for parsing and encoding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136479 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-29Avoid undefined behaviour if somehow NUM_GRAPHS equals 2^32 (orDuncan Sands
whatever the size of unsigned is), though this can't actually occur for any integer value of NUM_NODES. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136460 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29Teach Path::GetCurrentDirectory to use $PWD, to support users who like to doNick Lewycky
screwy things by setting PWD != getcwd(). For example, some developers I know will use this to control the value in gcc's DW_AT_comp_dir value in debug output. With this patch, that trick will now work on clang too. The only other effect of this change is that the static analysis will now respect $PWD when reporting the directory of the files in its HTML output. I think that's fine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136459 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29Fix a lot of typos, improve (but not necessarily fix) grammaros and reflow someNick Lewycky
lines. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136458 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29Misc optimizer+codegen work for 'cmpxchg' and 'atomicrmw'. They appear to beEli Friedman
working on x86 (at least for trivial testcases); other architectures will need more work so that they actually emit the appropriate instructions for orderings stricter than 'monotonic'. (As far as I can tell, the ARM, PPC, Mips, and Alpha backends need such changes.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136457 91177308-0d34-0410-b5e6-96231b3b80d8

rounding errors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136456 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29Fix the MCDisassembler dependencies. These were just absurdly wrong.Chandler Carruth
First off, only depend on the actual MC-ized disassemblers in the targets, not all of the libraries those in turn depend on. Second off, only depend on those MC-ized disassemblers for targets we're building. This should fix builds of fewer than all targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136455 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-29Transfer implicit operands in NEONMoveFixPass.Jakob Stoklund Olesen
Later passes /are/ using this information when running the register scavenger. This fixes the second problem in PR10520. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136440 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29Add -verify-arm-pseudo-expand.Jakob Stoklund Olesen
This hidden llc option runs the machine code verifier after expanding ARM pseudo-instructions, but before if-conversion. The machine code verifier is much better at pointing out liveness errors that can trip up the register scavenger. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136439 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-29Rewrite the CMake build to use explicit dependencies between libraries,Chandler Carruth
specified in the same file that the library itself is created. This is more idiomatic for CMake builds, and also allows us to correctly specify dependencies that are missed due to bugs in the GenLibDeps perl script, or change from compiler to compiler. On Linux, this returns CMake to a place where it can relably rebuild several targets of LLVM. I have tried not to change the dependencies from the ones in the current auto-generated file. The only places I've really diverged are in places where I was seeing link failures, and added a dependency. The goal of this patch is not to start changing the dependencies, merely to move them into the correct location, and an explicit form that we can control and change when necessary. This also removes a serialization point in the build because we don't have to scan all the libraries before we begin building various tools. We no longer have a step of the build that regenerates a file inside the source tree. A few other associated cleanups fall out of this. This isn't really finished yet though. After talking to dgregor he urged switching to a single CMake macro to construct libraries with both sources and dependencies in the arguments. Migrating from the two macros to that style will be a follow-up patch. Also, llvm-config is still generated with GenLibDeps.pl, which means it still has slightly buggy dependencies. The internal CMake 'llvm-config-like' macro uses the correct explicitly specified dependencies however. A future patch will switch llvm-config generation (when using CMake) to be based on these deps as well. This may well break Windows. I'm getting a machine set up now to dig into any failures there. If anyone can chime in with problems they see or ideas of how to solve them for Windows, much appreciated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136433 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-28Visit the landingpad instruction.Bill Wendling
This generates the correct SDNodes for the landingpad instruction. It makes an assumption that the result of the landingpad instruction has at least two values. And that the first value is a pointer to the exception object and the second value is the "selector." git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136430 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-28Add the AddLandingPadInfo function.Bill Wendling
AddLandingPadInfo takes a landingpad instruction and grabs all of the information from it that it needs for EH table generation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136429 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-28Change LBH_TAKEN_WEIGHT to 124 (from 128). Right now, sum ofJakub Staszak
LBH_TAKEN_WEIGHT + LBH_NONTAKEN_WEIGHT = 128 which in _most_ cases reduce number of rounding errors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136428 91177308-0d34-0410-b5e6-96231b3b80d8
