2010-01-27Kill ModuleProvider and ghost linkage by inverting the relationship betweenJeffrey Yasskin
Modules and ModuleProviders. Because the "ModuleProvider" simply materializes GlobalValues now, and doesn't provide modules, it's renamed to "GVMaterializer". Code that used to need a ModuleProvider to materialize Functions can now materialize the Functions directly. Functions no longer use a magic linkage to record that they're materializable; they simply ask the GVMaterializer. Because the C ABI must never change, we can't remove LLVMModuleProviderRef or the functions that refer to it. Instead, because Module now exposes the same functionality ModuleProvider used to, we store a Module* in any LLVMModuleProviderRef and translate in the wrapper methods. The bindings to other languages still use the ModuleProvider concept. It would probably be worth some time to update them to follow the C++ more closely, but I don't intend to do it. Fixes http://llvm.org/PR5737 and http://llvm.org/PR5735. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94686 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-23Prune #includes from llvm/Linker.h and llvm/System/Path.h,Chris Lattner
forcing them down into various .cpp files. This change also: 1. Renames TimeValue::toString() and Path::toString() to ::str() for similarity with the STL. 2. Removes all stream insertion support for sys::Path, forcing clients to call .str(). 3. Removes a use of Config/alloca.h from bugpoint, using smallvector instead. 4. Weans llvm-db off <iostream> sys::Path really needs to be gutted, but I don't have the desire to do it at this point. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79869 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-01Add a pointer to the owning LLVMContext to Module. This requires threading ↵Owen Anderson

2008-07-28Fold the useful features of alist and alist_node into ilist, andDan Gohman
a new ilist_node class, and remove them. Unlike alist_node, ilist_node doesn't attempt to manage storage itself, so it avoids the associated problems, including being opaque in gdb. Adjust the Recycler class so that it doesn't depend on alist_node. Also, change it to use explicit Size and Align parameters, allowing it to work when the largest-sized node doesn't have the greatest alignment requirement. Change MachineInstr's MachineMemOperand list from a pool-backed alist to a std::list for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54146 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-01Change the MemoryBuffer::getFile* methods to take just a pointer to theChris Lattner
start of a filename, not a filename+length. All clients can produce a null terminated name, and the system api's require null terminated strings anyway. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49041 91177308-0d34-0410-b5e6-96231b3b80d8
