gccgo successfully compiles the following program:

package a
const d rune = 1e2|2

gc and go/types reject this program saying:

illegal constant expression: untyped number | untyped number
invalid operation: operator | not defined for 1e2 (untyped float constant 100)

gcc version 6.0.0 2015070 (experimental) (GCC)
