[LLVMdev] PROPOSAL: LLVM_FALLTHROUGH macro for intended fall-throughs between switch cases
...o wrap
[[clang::fallthrough]]to a macro, so the code would continue to work
in c++98 mode, but in c++11
mode it would also allow to run this diagnostic (btw, is llvm compilable in
c++11 mode?). Sample implementation of the macro (see *
fallthrough-macro.diff*):
*#ifdef __clang__
**#if __has_feature(cxx_attributes) &&
__has_warning("-Wimplicit-fallthrough")
*
*#define LLVM_FALLTHROUGH [[clang::fallthrough]]
**#endif
**#endif
****#ifndef LLVM_FALLTHROUGH
**#define LLVM_FALLTHROUGH do { } while (0)
**#endif*
After this we can start using *-Wimplicit-fallthrough*.
Please express your opinion...
