2009-07-22Introduce MetadataBase, a base class for MDString and MDNode.Devang Patel
Derive MDString directly from MetadataBase. Introduce new bitcode block to hold metadata. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76759 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-07LLVMContext-ify the bitcode reader.Owen Anderson

2009-07-01Make the use of const with respect to LLVMContext sane. Hopefully this is ↵Owen Anderson
the last time, for the moment, that I will need to make far-reaching changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74655 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-01Hold the LLVMContext by reference rather than by pointer.Owen Anderson
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74640 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-01Add a pointer to the owning LLVMContext to Module. This requires threading ↵Owen Anderson
LLVMContext through a lot of the bitcode reader and ASM parser APIs, as well as supporting it in all of the tools. Patches for Clang and LLVM-GCC to follow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74614 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-26Make a major API change to BitstreamReader: split all the readingChris Lattner
state out of the BitstreamReader class into a BitstreamCursor class. Doing this allows the client to have multiple cursors into the same file, each with potentially different live block stacks and abbreviation records. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70157 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-31reimplement BitcodeReaderValueList in terms of WeakVH instead of makingChris Lattner
it be an LLVM IR User object. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68156 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-26Now Attributes are divided in three groupsDevang Patel
- return attributes - inreg, zext and sext - parameter attributes - function attributes - nounwind, readonly, readnone, noreturn Return attributes use 0 as the index. Function attributes use ~0U as the index. This patch requires corresponding changes in llvm-gcc and clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56704 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-25 Large mechanical patch.Devang Patel
s/ParamAttr/Attribute/g s/PAList/AttrList/g s/FnAttributeWithIndex/AttributeWithIndex/g s/FnAttr/Attribute/g This sets the stage - to implement function notes as function attributes and - to distinguish between function attributes and return value attributes. This requires corresponding changes in llvm-gcc and clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56622 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-21recommit bcreader, handling packed structs correctly. ApparentlyChris Lattner
people want fast *and* correct. Sheesh. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55102 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-12Reimplement the parameter attributes support, phase #1. hilights:Chris Lattner
1. There is now a "PAListPtr" class, which is a smart pointer around the underlying uniqued parameter attribute list object, and manages its refcount. It is now impossible to mess up the refcount. 2. PAListPtr is now the main interface to the underlying object, and the underlying object is now completely opaque. 3. Implementation details like SmallVector and FoldingSet are now no longer part of the interface. 4. You can create a PAListPtr with an arbitrary sequence of ParamAttrsWithIndex's, no need to make a SmallVector of a specific size (you can just use an array or scalar or vector if you wish). 5. All the client code that had to check for a null pointer before dereferencing the pointer is simplified to just access the PAListPtr directly. 6. The interfaces for adding attrs to a list and removing them is a bit simpler. Phase #2 will rename some stuff (e.g. PAListPtr) and do other less invasive changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48289 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-29Remove attribution from file headers, per discussion on llvmdev.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45418 91177308-0d34-0410-b5e6-96231b3b80d8
2007-08-04This is the patch to provide clean intrinsic function overloading support in ↵Chandler Carruth
LLVM. It cleans up the intrinsic definitions and generally smooths the process for more complicated intrinsic writing. It will be used by the upcoming atomic intrinsics as well as vector and float intrinsics in the future. This also changes the syntax for llvm.bswap, llvm.part.set, llvm.part.select, and llvm.ct* intrinsics. They are automatically upgraded by both the LLVM ASM reader and the bitcode reader. The test cases have been updated, with special tests added to ensure the automatic upgrading is supported. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40807 91177308-0d34-0410-b5e6-96231b3b80d8

2007-04-29Switch the bitcode reader interface to take a MemoryBuffer instead of knowingChris Lattner
anything about disk I/O itself. This greatly simplifies its interface - eliminating the need for the ReaderWrappers.cpp file. This adds a new option to llvm-dis (-bitcode) which instructs it to read the input file as bitcode. Until/unless the bytecode reader is taught to read from MemoryBuffer, there is no way to handle stdin reading without it. I don't plan to switch the bytecode reader over, I'd rather delete it :), so the option will stay around temporarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@36554 91177308-0d34-0410-b5e6-96231b3b80d8
