The code in the C front end that handles this is in finish_decl, in c-decl.c:
if (TREE_CODE (decl) == FUNCTION_DECL && asmspec)
{
if (DECL_BUILT_IN_CLASS (decl) == BUILT_IN_NORMAL)
{
tree builtin = built_in_decls [DECL_FUNCTION_CODE (decl)];
set_user_assembler_name (builtin, asmspec);
if (DECL_FUNCTION_CODE (decl) == BUILT_IN_MEMCPY)
init_block_move_fn (asmspec);
else if (DECL_FUNCTION_CODE (decl) == BUILT_IN_MEMSET)
init_block_clear_fn (asmspec);
}
set_user_assembler_name (decl, asmspec);
}
