Added LLVM_ENABLE_RTTI and LLVM_ENABLE_EH options that allow RTTI and EH to globally be controlled. Individual targets (e.g. ExceptionDemo) can still override this by using LLVM_REQUIRE_RTTI and LLVM_REQUIRE_EH if they need to be compiled with RTTI or exception handling respectively. llvm-svn: 213663 2014-07-22 23:41:18 +08:00			`# Enable EH and RTTI for this demo`

llvm/examples: Suppress building a few JIT examples. examples/ExceptionDemo/CMakeFiles/ExceptionDemo.dir/ExceptionDemo.cpp.o:(.data.rel.ro._ZTIN4llvm18MCJITMemoryManagerE[_ZTIN4llvm18MCJITMemoryManagerE]+0x10): undefined reference to `typeinfo for llvm::RuntimeDyld::MemoryManager' llvm-svn: 233647 2015-03-31 08:03:43 +08:00
Adds a JIT based exception handling example to the examples directory. Both zero cost example domain specific, and C++ foreign exception handling are shown. The example's documentation fully explains how to run the example. Notes: 1) The code uses an extremely simple type info model. 2) Only a single landing pad is used per unwind edge (one call to llvm.eh.selector) 3) llvm.eh.selector support for filter arguments is not given. 4) llvm.eh.typeid.for is not used. 5) Forced unwind behavior is not supported. 6) Very little if any error handling is given. 7) __attribute__((__aligned__)) is used. 8) The code uses parts from the llvm compiler-rt project and the llvm Kaleidoscope example. 9) The code has not been ported or tested on WINDOWS. 10) The code was not tested with a cmake build. 11) The code was tested for a debug build on 32bit X86 CentOS LINUX, and both a debug and release build on OS X 10.6.2 (64bit). llvm-svn: 95723 2010-02-10 07:22:43 +08:00			`add_llvm_example(ExceptionDemo`

The exception demo needs its symbols exported. llvm-svn: 180622 2013-04-27 03:07:40 +08:00
CMake: Disable ENABLE_EXPORTS for executables with MSVC 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re-link executables with ENABLE_EXPORTS because the .lib output file was not present, and therefore the target was out of date. llvm-svn: 232662 2015-03-19 04:09:13 +08:00			`export_executable_symbols(ExceptionDemo)`
