Have you actually tried compiling code identical to that you test but with 8388608L in place of (1L << 23) before making claims about what is done with constant expressions? Your example may suggest a regression, provided no type sizes changed for your target between the versions compared, but you really shouldn't report conjectures about the cause of a bug without clear evidence to substantiate them, which in this case would involve substituting the value of the constant expression in the testcase. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18424
