2010-08-20Create the new linker type "linker_private_weak_def_auto".Bill Wendling
It's similar to "linker_private_weak", but it's known that the address of the object is not taken. For instance, functions that had an inline definition, but the compiler decided not to inline it. Note, unlike linker_private and linker_private_weak, linker_private_weak_def_auto may have only default visibility. The symbols are removed by the linker from the final linked image (executable or dynamic library). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111684 91177308-0d34-0410-b5e6-96231b3b80d8

not part of the IR, are not uniqued, and may be safely RAUW'd. This replaces a variety of alternate mechanisms for achieving the same effect. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111681 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-21Disallow null as a named metadata operand.Dan Gohman
Make MDNode::destroy private. Fix the one thing that used MDNode::destroy, outside of MDNode itself. One should never delete or destroy an MDNode explicitly. MDNodes implicitly go away when there are no references to them (implementation details aside). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@109028 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-20Add support for remapping metadata kind IDs when reading in aDan Gohman
bitcode file, so that two bitcode files where the same metadata kind name happens to have been assigned a different ID can still be linked together. Eliminate the restriction that metadata kind IDs can't be 0. Change MD_dbg from 1 to 0, because we can now, and because it's less mysterious that way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108939 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-01Implement the "linker_private_weak" linkage type. This will be used forBill Wendling
Objective-C metadata types which should be marked as "weak", but which the linker will remove upon final linkage. However, this linkage isn't specific to Objective-C. For example, the "objc_msgSend_fixup_alloc" symbol is defined like this: .globl l_objc_msgSend_fixup_alloc .weak_definition l_objc_msgSend_fixup_alloc .section __DATA, __objc_msgrefs, coalesced .align 3 l_objc_msgSend_fixup_alloc: .quad _objc_msgSend_fixup .quad L_OBJC_METH_VAR_NAME_1 This is different from the "linker_private" linkage type, because it can't have the metadata defined with ".weak_definition". Currently only supported on Darwin platforms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107433 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-27Don't flush the raw_ostream in llvm::WriteBitcodeToFile; it's atDan Gohman
the wrong level. Clients which need to leave the stream open but which still require the bitcode bits to be on disk should call flush themselves. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104885 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-27Don't special-case stdout in llvm::WriteBitcodeToFile; just considerDan Gohman
it to be the caller's responsibility to provide a stream in binary mode. This fixes a layering violation and avoids an outs() call. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104878 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-03Add special case bitcode support for DebugLoc. This avoidsChris Lattner
having the bitcode writer materialize mdnodes for all the debug location tuples when writing out the bc file and stores the information in a more compact form. For example, the -O0 -g bc file for combine.c in 176.gcc shrinks from 739392 to 512096 bytes. This concludes my planned short-term debug info work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100261 91177308-0d34-0410-b5e6-96231b3b80d8

likely not a bitcode file at all, rather than being a bitcode file which is truncated. Check for this case and issue a more relevant error message. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100156 91177308-0d34-0410-b5e6-96231b3b80d8
