H A D | align.c | 31bfdb03 Tue Aug 29 23:12:40 CDT 2017 Paul Mackerras <paulus@ozlabs.org> powerpc: Use instruction emulation infrastructure to handle alignment faults
This replaces almost all of the instruction emulation code in fix_alignment() with calls to analyse_instr(), emulate_loadstore() and emulate_dcbz(). The only emulation code left is the SPE emulation code; analyse_instr() etc. do not handle SPE instructions at present.
One result of this is that we can now handle alignment faults on all the new VSX load and store instructions that were added in POWER9. VSX loads/stores will take alignment faults for unaligned accesses to cache-inhibited memory.
Another effect is that we no longer rely on the DAR and DSISR values set by the processor.
With this, we now need to include the instruction emulation code unconditionally.
