2016-11-20ExceptionDemo: remove some undefined behaviourSaleem Abdulrasool
The casting based reading of the LSDA could attempt to read unsuitably aligned data. Avoid that case by explicitly using a memcpy. A similar approach is used in libc++abi to address the same UB. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@287479 91177308-0d34-0410-b5e6-96231b3b80d8
2016-11-20ExceptionDemo: prefer headers over redeclarationsSaleem Abdulrasool
Rather than redeclaring the interfaces for exceptions, prefer using the `unwind.h` header. This is vended by at least gcc and clang, and can also be found by an external unwinding library (e.g. libunwind). Doing this simplifies the example to the exception handling itself. Minor tweaks are the result of _Unwind_Context_t not being defined, which is just a typedef for struct _Unwind_Context *.

2015-03-18CMake: Disable ENABLE_EXPORTS for executables with MSVCReid Kleckner
The MSVC linker won't produce a .lib file for an executable that doesn't export anything, and LLVM doesn't maintain dllexport annotations or .def files listing all C++ symbols. It also doesn't support exporting all symbols, like binutils ld. CMake 3.2 changed the Ninja generator to list both the .exe and .lib files as outputs of executable build targets. Ninja would always re-link executables with ENABLE_EXPORTS because the .lib output file was not present, and therefore the target was out of date. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@232662 91177308-0d34-0410-b5e6-96231b3b80d8

2015-03-04Make DataLayout Non-Optional in the ModuleMehdi Amini
Summary: DataLayout keeps the string used for its creation. As a side effect it is no longer needed in the Module. This is "almost" NFC, the string is no longer canonicalized, you can't rely on two "equals" DataLayout having the same string returned by getStringRepresentation(). Get rid of DataLayoutPass: the DataLayout is in the Module The DataLayout is "per-module", let's enforce this by not duplicating it more than necessary. One more step toward non-optionality of the DataLayout in the module. Make DataLayout Non-Optional in the Module Module->getDataLayout() will never returns nullptr anymore.

2015-02-13[PM] Update the examples to reflect the removal of theChandler Carruth
llvm/PassManager.h wrapper header and its using declarations. These now directly use the legacy namespace.

2015-02-13[PM] Remove the old 'PassManager.h' header file at the top level ofChandler Carruth
LLVM's include tree and the use of using declarations to hide the 'legacy' namespace for the old pass manager. This undoes the primary modules-hostile change I made to keep out-of-tree targets building. I sent an email inquiring about whether this would be reasonable to do at this phase and people seemed fine with it, so making it a reality. This should allow us to start bootstrapping with modules to a certain extent along with making it easier to mix and match headers in general. The updates to any code for users of LLVM are very mechanical. Switch from including "llvm/PassManager.h" to "llvm/IR/LegacyPassManager.h". Qualify the types which now produce compile errors with "legacy::". The most common ones are "PassManager", "PassManagerBase", and "FunctionPassManager". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@229094 91177308-0d34-0410-b5e6-96231b3b80d8

2014-09-10Add doInitialization/doFinalization to DataLayoutPass.Rafael Espindola
With this a DataLayoutPass can be reused for multiple modules. Once we have doInitialization/doFinalization, it doesn't seem necessary to pass a Module to the constructor. Overall this change seems in line with the idea of making DataLayout a required part of Module. With it the only way of having a DataLayout used is to add it to the Module. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@217548 91177308-0d34-0410-b5e6-96231b3b80d8

2014-02-25Use DataLayout from the module when easily available.Rafael Espindola
Eventually DataLayoutPass should go away, but for now that is the only easy way to get a DataLayout in some APIs. This patch only changes the ones that have easy access to a Module. One interesting issue with sometimes using DataLayoutPass and sometimes fetching it from the Module is that we have to make sure they are equivalent. We can get most of the way there by always constructing the pass with a Module. In fact, the pass could be changed to point to an external DataLayout instead of owning one to make this stricter. Unfortunately, the C api passes a DataLayout, so it has to be up to the caller to make sure the pass and the module are in sync. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202204 91177308-0d34-0410-b5e6-96231b3b80d8

2014-02-19Add back r201608, r201622, r201624 and r201625Rafael Espindola
r201608 made llvm corretly handle private globals with MachO. r201622 fixed a bug in it and r201624 and r201625 were changes for using private linkage, assuming that llvm would do the right thing. They all got reverted because r201608 introduced a crash in LTO. This patch includes a fix for that. The issue was that TargetLoweringObjectFile now has to be initialized before we can mangle names of private globals. This is trivially true during the normal codegen pipeline (the asm printer does it), but LTO has to do it manually. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201700 91177308-0d34-0410-b5e6-96231b3b80d8
2014-02-19This reverts commit r201625 and r201624.Rafael Espindola
