Analyzing Left-Shift Overflow Behavior Across Integer Types in C and C++
Bitwise Left-Shift Boundary Conditions
Left-shift operations (<<) on fixed-width integers frequently cross architectural boundaries, triggering overflow semantics that differ between signed and unsigned representations. This investigation evaluates how C and C++ compilers handle shift counts that meet or exceed the operand bit-width (32 a ...
