Bug ID: 112650
Summary: RISC-V parameters are not documented
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: jeremy.bennett at embecosm dot com
Target Milestone: ---
GCC for RISC-V defines several parameters to control compilation:
- riscv-strcmp-inline-limit
- riscv-autovec-preference
- riscv-autovec-lmul
- riscv-vector-abi
The last of these is commented as an undocumented experimental switch in
riscv.opt
None of these parameters are included in the user manual (specifically in the
"RISC-V Options" section of invoke.texi). While parameters often relate to
internal interfaces, and hence are unstable, they are still available to the
user, and should be documented accordingly.
The "Arm Options" section includes a good reference for such documentation,
including warning about the unstable nature of parameters.
