C++ (Cpp) gencall_throw Examples

Example #1

File: gencontrol.c Project: Sendence/ponyc

LLVMValueRef gen_error(compile_t* c, ast_t* ast)
{
  size_t clause;
  ast_t* try_expr = ast_try_clause(ast, &clause);

  // Do the then block only if we error out in the else clause.
  if((try_expr != NULL) && (clause == 1))
    gen_expr(c, ast_childidx(try_expr, 2));

  codegen_scope_lifetime_end(c);
  codegen_debugloc(c, ast);
  gencall_throw(c);
  codegen_debugloc(c, NULL);

  return GEN_NOVALUE;
}

Example #2

File: genprim.c Project: georgemarrows/ponyc

{
  // Returns the receiver if it isn't null.
  FIND_METHOD("apply");
