A simple patch adding `MO_TE` to 3 instructions under `/target/riscv/insn_trans/trans_rvzce.c.inc` fixes the bug (for the minimal reproducer at least). It is available in the following ppa: https://launchpad.net/~vhaudiquet/+archive/ubuntu/qemu-fix-lp2123828/+packages
I will keep checking to see if the flag is missing from other instructions :) -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/2123828 Title: RISC-V: incorrect emulation of load and store on big-endian systems Status in QEMU: New Status in gcc-15 package in Ubuntu: Invalid Status in glibc package in Ubuntu: Invalid Status in qemu package in Ubuntu: Confirmed Bug description: QEMU's DEP-8 test fails on s390x, due to warning output on stderr about "unsupported version 256 of Verdef record", which is blocking migration of glibc 2.42-0ubuntu3.
