The Intel 8080 and Z80 had conditional call instructions. Don't know why x86 didn't deem them important enough to drag them along though.

x86 had INTO, interrupt when overflow, which basically gave this functionality. It would allow software to treat an overflow basically like a segmentation violation.
It never saw much use, and got removed in x64.
