* [WIP] Initial code for module flags.Bill Wendling2012-02-1112-0/+110
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Module flags are key-value pairs associated with the module. They include a 'behavior' value, indicating how module flags react when mergine two files. Normally, it's just the union of the two module flags. But if two module flags have the same key, then the resulting flags are dictated by the behaviors. Allowable behaviors are: Error Emits an error if two values disagree. Warning Emits a warning if two values disagree. Require Emits an error when the specified value is not present or doesn't have the specified value. It is an error for two (or more) llvm.module.flags with the same ID to have the Require behavior but different values. There may be multiple Require flags per ID. Override Uses the specified value if the two values disagree. It is an error for two (or more) llvm.module.flags with the same ID to have the Override behavior but different values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150300 91177308-0d34-0410-b5e6-96231b3b80d8

* Land the long talked about "type system rewrite" patch. ThisChris Lattner2011-07-097-47/+116
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | patch brings numerous advantages to LLVM. One way to look at it is through diffstat: 109 files changed, 3005 insertions(+), 5906 deletions(-) Removing almost 3K lines of code is a good thing. Other advantages include: 1. Value::getType() is a simple load that can be CSE'd, not a mutating union-find operation. 2. Types a uniqued and never move once created, defining away PATypeHolder. 3. Structs can be "named" now, and their name is part of the identity that uniques them. This means that the compiler doesn't merge them structurally which makes the IR much less confusing. 4. Now that there is no way to get a cycle in a type graph without a named struct type, "upreferences" go away. 5. Type refinement is completely gone, which should make LTO much MUCH faster in some common cases with C++ code. 6. Types are now generally immutable, so we can use "Type *" instead "const Type *" everywhere. Downsides of this patch are that it removes some functions from the C API, so people using those will have to upgrade to (not yet added) new API. "LLVM 3.0" is the right time to do this. There are still some cleanups pending after this, this patch is large enough as-is. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134829 91177308-0d34-0410-b5e6-96231b3b80d8

* Reapply r112091 and r111922, support for metadata linking, with aDan Gohman2010-08-262-0/+24
| | | | | | | | | | | | | | | fix: add a flag to MapValue and friends which indicates whether any module-level mappings are being made. In the common case of inlining, no module-level mappings are needed, so MapValue doesn't need to examine non-function-local metadata, which can be very expensive in the case of a large module with really deep metadata (e.g. a large C++ program compiled with -g). This flag is a little awkward; perhaps eventually it can be moved into the ClonedCodeInfo class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112190 91177308-0d34-0410-b5e6-96231b3b80d8

* When a constant's type is refined, update the constant in placeDan Gohman2009-09-152-0/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | instead of cloning and RAUWing it. - Make AbstractTypeUser a friend of Value so that it can offer its subclasses a way to update a Value's type in place. This is better than a universally visible setType method on Value, and it's sufficient for the immediate need. - Eliminate the constant "convert" functions. This eliminates a lot of logic duplication, and fixes a complicated bug where a constant can't actually be cloned during the type refinement process because some of the types that its folder needs are half-destroyed, being in the middle of refinement themselves. - Move the getValType functions from being static overloaded functions in Constants.cpp to be members of class template specializations in ConstantsContext.h. This means that the code ends up getting instantiated twice, however it also makes it possible to eliminate all "convert" functions, so it's not a big net code size increase. And if desired, the duplicate instantiations could be eliminated with some reorganization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81861 91177308-0d34-0410-b5e6-96231b3b80d8

* Reimplement the old and horrible bison parser for .ll files with a niceChris Lattner2009-01-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and clean recursive descent parser. This change has a couple of ramifications: 1. The parser code is about 400 lines shorter (in what we maintain, not including what is autogenerated). 2. The code should be significantly faster than the old code because we don't have to work around bison's poor handling of datatypes with ctors/dtors. This also makes the code much more resistant to memory leaks. 3. We now get caret diagnostics from the .ll parser, woo. 4. The actual diagnostics emited from the parser are completely different so a bunch of testcases had to be updated. 5. I now disallow "%ty = type opaque %ty = type i32". There was no good reason to support this, it was just an accident of the old implementation. I have no reason to think that anyone is actually using this. 6. The syntax for sticking a global variable has changed to make it unambiguous. I don't think anyone is depending on this since only clang supports this and it is not solid yet, so I'm not worried about anything breaking. 7. This gets rid of the last use of bison, and along with it the .cvs files. I'll prune this from the makefiles as a subsequent commit. There are a few minor cleanups that can be done after this commit (suggestions welcome!) but this passes dejagnu testing and is ready for its time in the limelight. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61558 91177308-0d34-0410-b5e6-96231b3b80d8

First, this causes a regression in 2008-07-06-AliasWeakDest.ll, which is now failing (so I xfailed it). Anton, I would really appreciate it if you could take a look at this. It should be a matter of adding proper alias support to GetLinkageResult, and was probably already a latent bug that would manifest with globals. The second todo is to reimplement LinkAlias in the same pattern as function and global linking. This should be pretty straight-forward for someone who knows aliases, but isn't a requirement for correctness. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53548 91177308-0d34-0410-b5e6-96231b3b80d8
