* Have the bitcode writer and reader handle the new attribute references.Bill Wendling2013-02-122-33/+11
| | | | | | | | The bitcode writer emits a reference to the attribute group that the object at the given index refers to. The bitcode reader is modified to read this in and map it back to the attribute group. llvm-svn: 174952
* Use the AttributeSet as the 'key' to the map instead of the 'raw' pointer.Bill Wendling2013-02-122-5/+6
| | | | llvm-svn: 174950
* Rename AttributeSets to AttributeGroups so that it's more meaningful.Bill Wendling2013-02-113-41/+41
| | | | llvm-svn: 174911
* Use a std::map so that we record the group ID.Bill Wendling2013-02-112-7/+8

| | | | llvm-svn: 174864
* Fix unnecessary removal of const through cast machineryDavid Blaikie2013-02-111-4/+4
| | | | | | | | I have some uncommitted changes to the cast code that catch this sort of thing at compile-time but I still need to do some other cleanup before I can enable it. llvm-svn: 174853
* Add support in the bitcode reader to read the attribute groups.Bill Wendling2013-02-102-0/+82
| | | | | | | | | This reads the attribute groups. It currently doesn't do anything with them. NOTE: In the commit to the bitcode writer, the format *may* change in the near future. Which means that this code would also change. llvm-svn: 174849
* Add code for emitting the attribute groups.Bill Wendling2013-02-101-0/+53
| | | | | | | | | This is some initial code for emitting the attribute groups into the bitcode. NOTE: This format *may* change! Do not rely upon the attribute groups' bitcode not changing. llvm-svn: 174845
* Add support for attribute groups in the value enumerator.Bill Wendling2013-02-102-0/+24
| | | | | | | Attribute groups are essentially all AttributeSets which are used by the program. Enumerate them here. llvm-svn: 174844
* Fix the underlying problem that was causing read(0) to be called: sometimes theChris Lattner2013-02-091-3/+14
| | | | | | | | | | | | | | | bitcode writer would generate abbrev records saying that the abbrev should be filled with fixed zero-bit bitfields (this happens in the .bc writer when the number of types used in a module is exactly one, since log2(1) == 0). In this case, just handle it as a literal zero. We can't "just fix" the writer without breaking compatibility with existing bc files, so have the abbrev reader do the substitution. Strengthen the assert in read to reject reads of zero bits so we catch such crimes in the future, and remove the special case designed to handle this. llvm-svn: 174801

| | | | | | externally_initialized. llvm-svn: 174340
* Initial cleanups of the param-attribute code in the bitcode reader/writer.Bill Wendling2013-02-042-7/+49
| | | | | | | | | Rename the PARAMATTR_CODE_ENTRY to PARAMATTR_CODE_ENTRY_OLD. It will be replaced by another encoding. Keep around the current LLVM attribute encoder/decoder code, but move it to the bitcode directories so that no one's tempted to use them. llvm-svn: 174335
* Use an AttrBuilder to generate the correct AttributeSet.Bill Wendling2013-01-291-9/+4
| | | | | | | | | We no longer accept an encoded integer as representing all of the attributes. Convert this via the AttrBuilder class into an AttributeSet with the correct representation (an AttributeSetImpl that holds a list of Attribute objects). llvm-svn: 173750
* Use the AttributeSet instead of AttributeWithIndex object.Bill Wendling2013-01-271-3/+2
| | | | llvm-svn: 173598
* Remove some introspection functions.Bill Wendling2013-01-252-4/+6
| | | | | | | | The 'getSlot' function and its ilk allow introspection into the AttributeSet class. However, that class should be opaque. Allow access through accessor methods instead. llvm-svn: 173522
* Use the new 'getSlotIndex' method to retrieve the attribute's slot index.Bill Wendling2013-01-251-1/+1
| | | | llvm-svn: 173499
* Make APFloat constructor require explicit semantics.Tim Northover2013-01-221-6/+12
| | | | | | | | | Previously we tried to infer it from the bit width size, with an added IsIEEE argument for the PPC/IEEE 128-bit case, which had a default value. This default value allowed bugs to creep in, where it was inappropriate. llvm-svn: 173138
* Fix a heinous inefficiency introduced in r149918, wherein reading each byte of aChris Lattner2013-01-211-9/+8
| | | | | | | | BLOB (i.e., large, performance intensive data) in a bitcode file was switched to invoking one virtual method call per byte read. Now we do one virtual call per BLOB. llvm-svn: 173065

* Move all of the header files which are involved in modelling the LLVM IRChandler Carruth2013-01-026-24/+24
| | | | | | | | | | | | | | | | | | | | | into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project. I'll be committing updates to Clang, DragonEgg, and Polly momentarily. llvm-svn: 171366

* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-034-12/+12
| | | | | | | | | | | | | | | | | Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] llvm-svn: 169131
* Add back support for reading and parsing 'deplibs'.Bill Wendling2012-11-281-0/+8

* Make the AttrListPtr object a part of the LLVMContext.Bill Wendling2012-11-201-1/+1
| | | | | | | | | When code deletes the context, the AttributeImpls that the AttrListPtr points to are now invalid. Therefore, instead of keeping a separate managed static for the AttrListPtrs that's reference counted, move it into the LLVMContext and delete it when deleting the AttributeImpls. llvm-svn: 168354

* Relax the restrictions on vector of pointer types, and vector getelementptr.Duncan Sands2012-11-131-5/+6
| | | | | | | | | | | | | | | Previously in a vector of pointers, the pointer couldn't be any pointer type, it had to be a pointer to an integer or floating point type. This is a hassle for dragonegg because the GCC vectorizer happily produces vectors of pointers where the pointer is a pointer to a struct or whatever. Vector getelementptr was restricted to just one index, but now that vectors of pointers can have any pointer type it is more natural to allow arbitrary vector getelementptrs. There is however the issue of struct GEPs, where if each lane chose different struct fields then from that point on each lane will be working down into unrelated types. This seems like too much pain for too little gain, so when you have a vector struct index all the elements are required to be the same. llvm-svn: 167828

* Attributes RewriteBill Wendling2012-10-151-3/+4
| | | | | | | | | | Convert the internal representation of the Attributes class into a pointer to an opaque object that's uniqued by and stored in the LLVMContext object. The Attributes class then becomes a thin wrapper around this opaque object. Eventually, the internal representation will be expanded to include attributes that represent code generation options, etc. llvm-svn: 165917
