[Qemu-devel] [PATCH] target/mips: Fix emulation of ST.W in system mode
Posted by Aleksandar Markovic 4 years, 7 months ago 
From: Aleksandar Markovic <amarkovic@wavecomp.com>

Order of arguments in helper_ret_stl_mmu() invocations was wrong,
apparently caused by misplaced multiline copy-and-paste.

Fixes: 6decc57 "target/mips: Fix MSA instructions ST.<B|H|W|D> on
big endian host"
