* Remove the Copied parameter from MemoryObject::readBytes.Benjamin Kramer2013-05-241-1/+1
| | | | | | | | | | There was exactly one caller using this API right, the others were relying on specific behavior of the default implementation. Since it's too hard to use it right just remove it and standardize on the default behavior. Defines away PR16132. llvm-svn: 182636

* Have the bitcode writer and reader handle the new attribute references.Bill Wendling2013-02-121-0/+8
| | | | | | | | 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 a std::map so that we record the group ID.Bill Wendling2013-02-111-6/+7

* Add support in the bitcode reader to read the attribute groups.Bill Wendling2013-02-101-0/+78
| | | | | | | | | 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

* Initial cleanups of the param-attribute code in the bitcode reader/writer.Bill Wendling2013-02-041-3/+23
| | | | | | | | | 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 Wendling2013-01-251-1/+1
| | | | | | | | 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
* 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

* Move all of the header files which are involved in modelling the LLVM IRChandler Carruth2013-01-021-7/+7
| | | | | | | | | | | | | | | | | | | | | 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 Carruth2012-12-031-4/+4
| | | | | | | | | | | | | | | | | 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
| | | | | | | This is for backwards compatibility for pre-3.x bc files. The code reads the code, but does nothing with it. llvm-svn: 168779

* Code Custodian:Joe Abbey2012-11-251-2/+2
| | | | | | | | - Widespread trailing space removal - A dash of OCD spacing to block align enums - joined a line that probably needed 80 cols a while back llvm-svn: 168566
* 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

* 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
* Remove unnecessary classof()'sSean Silva2012-10-111-1/+0
| | | | | | | isa<> et al. automatically infer when the cast is an upcast (including a self-cast), so these are no longer necessary. llvm-svn: 165767
* Change encoding of instruction operands in bitcode binaries to be relativeJan Wen Voung2012-10-111-37/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | to the instruction position. The old encoding would give an absolute ID which counts up within a function, and only resets at the next function. I.e., Instead of having: ... = icmp eq i32 n-1, n-2 br i1 ..., label %bb1, label %bb2 it will now be roughly: ... = icmp eq i32 1, 2 br i1 1, label %bb1, label %bb2 This makes it so that ids remain relatively small and can be encoded in fewer bits. With this encoding, forward reference operands will be given negative-valued IDs. Use signed VBRs for the most common case of forward references, which is phi instructions. To retain backward compatibility we bump the bitcode version from 0 to 1 to distinguish between the different encodings. llvm-svn: 165739

* Change the `linker_private_weak_def_auto' linkage to `linkonce_odr_auto_hide' toBill Wendling2012-08-171-1/+1
| | | | | | | | | | | | | | | | | | | | make it more consistent with its intended semantics. The `linker_private_weak_def_auto' linkage type was meant to automatically hide globals which never had their addresses taken. It has nothing to do with the `linker_private' linkage type, which outputs the symbols with a `l' (ell) prefix among other things. The intended semantic is more like the `linkonce_odr' linkage type. Change the name of the linkage type to `linkonce_odr_auto_hide'. And therefore changing the semantics so that it produces the correct output for the linker. Note: The old linkage name `linker_private_weak_def_auto' will still parse but is not a synonym for `linkonce_odr_auto_hide'. This should be removed in 4.0. <rdar://problem/11754934> llvm-svn: 162114

* Extend the IL for selecting TLS models (PR9788)Hans Wennborg2012-06-231-4/+15
| | | | | | | | | | | | | | | This allows the user/front-end to specify a model that is better than what LLVM would choose by default. For example, a variable might be declared as @x = thread_local(initialexec) global i32 42 if it will not be used in a shared library that is dlopen'ed. If the specified model isn't supported by the target, or if LLVM can make a better choice, a different model may be used. llvm-svn: 159077
