Architectures
ILP32 is not specific to one CPU. AArch64 is our first and most complete architecture.
| Architecture | ILP32 ABI | Upstream | Here |
|---|---|---|---|
| AArch64 | aarch64_ilp32 | kernel and glibc never merged; GCC 15 deprecated it | complete: kernel, glibc, musl, GCC, clang, ILP32Wrt, Debian packages |
| RISC-V | RV64ILP32 | experimental in the psABI; not in mainline Linux | to do |
| x86-64 | x32 | in mainline Linux and glibc since 2012 | precedent; nothing to add |
