C++ (Cpp) LLVMGetMDKindID Examples

Example #1

File: gencall.c Project: killerswan/ponyc

static void set_descriptor(compile_t* c, reach_type_t* t, LLVMValueRef value)
{
  if(t->underlying == TK_STRUCT)
    return;

  LLVMValueRef desc_ptr = LLVMBuildStructGEP(c->builder, value, 0, "");
  LLVMValueRef store = LLVMBuildStore(c->builder, t->desc, desc_ptr);
  const char id[] = "tbaa";
  LLVMSetMetadata(store, LLVMGetMDKindID(id, sizeof(id) - 1), c->tbaa_descptr);
}

Example #2

File: genoperator.c Project: enigma/ponyc

static LLVMValueRef assign_field(compile_t* c, LLVMValueRef l_value,
  LLVMValueRef r_value, ast_t* p_type, ast_t* r_type)
{
  LLVMValueRef result = LLVMBuildLoad(c->builder, l_value, "");

  // Cast the rvalue appropriately.
  LLVMTypeRef cast_type = LLVMGetElementType(LLVMTypeOf(l_value));
  LLVMValueRef cast_value = gen_assign_cast(c, cast_type, r_value, r_type);

  if(cast_value == NULL)
    return NULL;

  // Store to the field.
  LLVMValueRef store = LLVMBuildStore(c->builder, cast_value, l_value);

  LLVMValueRef metadata = tbaa_metadata_for_type(c, p_type);
  const char id[] = "tbaa";
  LLVMSetMetadata(result, LLVMGetMDKindID(id, sizeof(id) - 1), metadata);
  LLVMSetMetadata(store, LLVMGetMDKindID(id, sizeof(id) - 1), metadata);

  return result;
}

Example #3

File: metadata.c Project: jamboree/llvm

int llvm_set_metadata(void) {
  LLVMBuilderRef b = LLVMCreateBuilder();
  LLVMValueRef values[] = { LLVMConstInt(LLVMInt32Type(), 0, 0) };

  // This used to trigger an assertion
  LLVMSetMetadata(
      LLVMBuildRetVoid(b),
      LLVMGetMDKindID("kind", 4),
      LLVMMDNode(values, 1));

  LLVMDisposeBuilder(b);

  return 0;
}

Example #4

File: genreference.c Project: Sendence/ponyc

{
  AST_GET_CHILDREN(ast, left, right);
  ast_t* l_type = ast_type(left);

  // Don't load if we're reading from a tuple.
  if(ast_id(l_type) != TK_TUPLETYPE)
