[Qemu-devel] [PATCH v3 3/3] target/arm: Implement the ARMv8.1-LOR extension

2018-12-06 Thread Richard Henderson
Provide a trivial implementation with zero limited ordering regions, which causes the LDLAR and STLLR instructions to devolve into the LDAR and STLR instructions from the base ARMv8.0 instruction set. Signed-off-by: Richard Henderson --- v2: Mark LORID_EL1 read-only. Add TLOR access checks.
