------- Comment #3 from n dot pipenbrinck at cubic dot org 2008-09-24 22:41 ------- ROL/ROR on the native integer size is not supported via intrinsics, but the compiler will fold two shifts into a rotate.
If I want to manipulate only the lower 16 bit of an 32 bit integer (e.g. issue a rolw) assembly is the only way it's currently possible. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37621
