RISC-V Linux User ABI
=====================

Misaligned accesses are supported in userspace, but they may perform poorly.
doc: RISC-V: Document that misaligned accesses are supported The RISC-V ISA manual used to mandate that misaligned accesses were supported in user mode, but that requirement was removed in 2018 via riscv-isa-manual commit 61cadb9 ("Provide new description of misaligned load/store behavior compatible with privileged architecture."). Since the Linux uABI was already frozen at that point it's just been demoted to part of the uABI, but that was never written down.
