Despite its potential, x32 ABI also had several disadvantages. Using x32 ABI adds additional complexity for developers to deal with and requires compilers to support the feature. Arguably, its biggest technical problem relates to the fact that individual processes running with x32 ABI cannot take advantage of more than 4GB of memory due to the pointer sizes being limited to 32 bits.
That said, the nail in the coffin for x32 ABI is its lack of mainstream adoption by software developers as a whole. This was likely helped by the fact that x32 ABI was ever only implemented on Linux and was not ported to Windows or Mac. Sebastian Andrezj Siewior highlighted further issues in his proposal, noting that the better performance x32 ABI realized was not great enough for certain workloads to move to it and use it exclusively.
