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
2009-08-23eliminate the "Value" printing methods that print to a std::ostream.Chris Lattner

2009-07-31Move a few more APIs back to 2.5 forms. The only remaining ones left to ↵Owen Anderson
change back are metadata related, which I'm waiting on to avoid conflicting with Devang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77721 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-25Initial update to VMCore to use Twines for string arguments.Daniel Dunbar
- The only meat here is in Value.{h,cpp} the rest is essential 'const std::string &' -> 'const Twine &'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77048 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-20Add plumbing for the `linker_private' linkage type. This type is meant forBill Wendling
"private" symbols which the assember shouldn't strip, but which the linker may remove after evaluation. This is mostly useful for Objective-C metadata. This is plumbing, so we don't have a use of it yet. More to come, etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76385 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-14llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin
This adds location info for all llvm_unreachable calls (which is a macro now) in !NDEBUG builds. In NDEBUG builds location info and the message is off (it only prints "UREACHABLE executed"). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75640 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-11assert(0) -> LLVM_UNREACHABLE.Torok Edwin
Make llvm_unreachable take an optional string, thus moving the cerr<< out of line. LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for NDEBUG builds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75379 91177308-0d34-0410-b5e6-96231b3b80d8

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

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
2009-04-13Add a new "available_externally" linkage type. This is intendedChris Lattner
to support C99 inline, GNU extern inline, etc. Related bugzilla's include PR3517, PR3100, & PR2933. Nothing uses this yet, but it appears to work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68940 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-08Apply ODR linkage changes accidentally dropped duringDuncan Sands
final cleaning. This fixes a bunch of testsuite failures. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66380 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-07Introduce new linkage types linkonce_odr, weak_odr, common_odrDuncan Sands
and extern_weak_odr. These are the same as the non-odr versions, except that they indicate that the global will only be overridden by an *equivalent* global. In C, a function with weak linkage can be overridden by a function which behaves completely differently. This means that IP passes have to skip weak functions, since any deductions made from the function definition might be wrong, since the definition could be replaced by something completely different at link time. This is not allowed in C++, thanks to the ODR (One-Definition-Rule): if a function is replaced by another at link-time, then the new function must be the same as the original function. If a language knows that a function or other global can only be overridden by an equivalent global, it can give it the weak_odr linkage type, and the optimizers will understand that it is alright to make deductions based on the function body. The code generators on the other hand map weak and weak_odr linkage to the same thing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66339 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-14Reimplement LinkFunctionProtos in terms of GetLinkageResult. This fixesChris Lattner
the second half of link-global-to-func.ll and causes some minor changes in messages. There are two TODOs here. First, this causes a regression in 2008-07-06-AliasWeakDest.ll, which is now failing (so I xfailed it). Anton, I would really appreciate it if you could take a look at this. It should be a matter of adding proper alias support to GetLinkageResult, and was probably already a latent bug that would manifest with globals. The second todo is to reimplement LinkAlias in the same pattern as function and global linking. This should be pretty straight-forward for someone who knows aliases, but isn't a requirement for correctness. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53548 91177308-0d34-0410-b5e6-96231b3b80d8
