| | | | | | | | | one new .cpp file, in preparation for merging in the Direct Object Emission changes we're working on. No functional changes. Fixed coding style issues on the original patch. Patch by Aaron Gray git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72754 91177308-0d34-0410-b5e6-96231b3b80d8

* It makes no sense to have a ODR version of commonDuncan Sands2009-03-111-2/+1
| | | | | | | linkage, so remove it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66690 91177308-0d34-0410-b5e6-96231b3b80d8
* Introduce new linkage types linkonce_odr, weak_odr, common_odrDuncan Sands2009-03-071-3/+6
| | | | | | | | | | | | | | | | | | | | | | 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
* Add support to the JIT for true non-lazy operation. When a call to a functionNate Begeman2009-02-181-0/+5
| | | | | | | | | | | | | | | | | | | | | that has not been JIT'd yet, the callee is put on a list of pending functions to JIT. The call is directed through a stub, which is updated with the address of the function after it has been JIT'd. A new interface for allocating and updating empty stubs is provided. Add support for removing the ModuleProvider the JIT was created with, which would otherwise invalidate the JIT's PassManager, which is initialized with the ModuleProvider's Module. Add support under a new ExecutionEngine flag for emitting the infomration necessary to update Function and GlobalVariable stubs after JITing them, by recording the address of the stub and the name of the GlobalValue. This allows code to be copied from one address space to another, where libraries may live at different virtual addresses, and have the stubs updated with their new correct target addresses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64906 91177308-0d34-0410-b5e6-96231b3b80d8

This brings globals in line with the rest of LLVM: the space reserved for an object is now always the ABI size. One tricky point is that only 10 bytes should be output for long double if it is a field in a packed struct, which is the reason for the additional argument to EmitGlobalConstant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43688 91177308-0d34-0410-b5e6-96231b3b80d8

Use APFloat functions for constant folding arithmetic and comparisons. (There are still way too many places APFloat is just a wrapper around host float/double, but we're getting there.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41747 91177308-0d34-0410-b5e6-96231b3b80d8
