            Bug ID: 111557
           Summary: [RISC-V] The macro __riscv_unaligned_fast should be
                    __riscv_misaligned_fast
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: lasse.collin at tukaani dot org
  Target Milestone: ---

The RISC-V C API Specification[1] has __riscv_misaligned_fast,
__riscv_misaligned_slow, and __riscv_misaligned_avoid. The commit 6e23440b =
[2]
used "unaligned" instead of "misaligned" though. The spelling
__riscv_unaligned_* was mentioned in [3] but in [4] it was changed to
__riscv_misaligned_*.

Clang doesn't have these macros yet but there is a recent pull request[5] t=
hat
uses the __riscv_misaligned_* spelling.
