First ARMTargetParser FIXME, conservatively changing the way we parse CPUs in the back-end. Still not perfect, with a lot of special cases, but moving towards a more generic solution. Moving all logic to the target parser made some unwritten assumptions about architectures in Clang to break. I've added a lot of architectures required by Clang, and default to CPUs that Clang believes it should (and I agree). I've also added a lot of unit tests, with the correct CPU for each architecture, and Clang seems to be working correctly, too. It also became clear that using "unsigned ID" as the argument for the get methods makes it hard to know what ID, so I also changed the argument names to match the enum type names. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@237797 91177308-0d34-0410-b5e6-96231b3b80d8 |

Design Of lib/System ==================== The software in this directory is designed to completely shield LLVM from any and all operating system specific functionality. It is not intended to be a complete operating system wrapper (such as ACE), but only to provide the functionality necessary to support LLVM. The software located here, of necessity, has very specific and stringent design rules. Violation of these rules means that cracks in the shield could form and the primary goal of the library is defeated. By consistently using this library, LLVM becomes more easily ported to new platforms since the only thing requiring porting is this library. Complete documentation for the library can be found in the file: llvm/docs/SystemLibrary.html or at this URL: http://llvm.org/docs/SystemLibrary.html While we recommend that you read the more detailed documentation, for the impatient, here's a high level summary of the library's requirements. 1. No system header files are to be exposed through the interface. 2. Std C++ and Std C header files are okay to be exposed through the interface. 3. No exposed system-specific functions. 4. No exposed system-specific data. 5. Data in lib/System classes must use only simple C++ intrinsic types. 6. Errors are handled by returning "true" and setting an optional std::string 7. Library must not throw any exceptions, period. 8. Interface functions must not have throw() specifications. 9. No duplicate function impementations are permitted within an operating system class. To accomplish these requirements, the library has numerous design criteria that must be satisfied. Here's a high level summary of the library's design criteria: 1. No unused functionality (only what LLVM needs) 2. High-Level Interfaces 3. Use Opaque Classes 4. Common Implementations 5. Multiple Implementations 6. Minimize Memory Allocation 7. No Virtual Methods
