That is not a real bug, because the behaviour in that case is unpredictable (references in commit messages). v2: - Add consistency in DIV_U.df and DIV_S.df helper implementation - Adjust the commit messages and the cover letter, making them clearer and more understandable - Correct the spelling in the commit messages and in the cover letter Mateja Marjanovic (2): target/mips: Make the results of DIV_. the same as on hardware target/mips: Make the results of MOD_. the same as on hardware target/mips/msa_helper.c | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) -- 2.7.4
