[PATCH 13/18] bsd-user: Add generic RISC-V64 target definitions
Posted by Ajeet Singh 3 months, 3 weeks ago
From: Warner Losh <imp@bsdimp.com>

Added a generic definition for RISC-V64 target-specific details.
Implemented the 'regpairs_aligned' function,which returns 'false'
to indicate that register pairs are not aligned in the RISC-V64 ABI.
