[PATCH] D126559: [MSVC] Fix pragma alloc_text failing for C files

[Stephen Long via Phabricator via cfe-commits]

steplong added a comment.

I tried the following:

  FunctionDecl *FD = ND->getAsFunction();
  DeclContext *DC = ND->getDeclContext();
  DEBUG_WITH_TYPE("foo", llvm::dbgs() << "[FOO] DC->isExternCContext()         
: " << DC->isExternCContext()         << "\n");
  DEBUG_WITH_TYPE("foo", llvm::dbgs() << "[FOO] FD->isExternC()                
: " << FD->isExternC()                << "\n");
  DEBUG_WITH_TYPE("foo", llvm::dbgs() << "[FOO] FD->isInExternCContext()       
: " << FD->isInExternCContext()       << "\n");
  llvm::dbgs() << "[FOO] "; ND->dump();
  if (getLangOpts().CPlusPlus && !DC->isExternCContext()) {
    Diag(Loc, diag::err_pragma_alloc_text_c_linkage);
    return;
  }

and I'm getting the following output:

  [FOO] DC->isExternCContext()         : 0
  [FOO] FD->isExternC()                : 0
  [FOO] FD->isInExternCContext()       : 0
  [FOO] FunctionDecl 0x10ec0250 prev 0x10ec0148 <foo.cpp:4:1, col:17> col:13 
foo 'void ()' static

The C file is:

  1 extern "C" {
  2 static void foo();
  3 }
  4 static void foo();
  5 #pragma alloc_text("s", foo)
  6 static void foo() {}
