[Qemu-devel] [PATCH v2 0/2] target/mips: Adjusting the results when dividing by zero in MSA instructions

[Mateja Marjanovic]

From: Mateja Marjanovic <address@hidden>

The behaviour when executing DIV_<U|S>.<B|H|W|D> and MOD_<U|S>.<B|H|W|D>
differs on a referent hardware (FPGA MIPS 64 r6, little endian) and on
QEMU, when the divisor is equal to zero. 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_<U|S>.<B|H|W|D> the same as on
    hardware
  target/mips: Make the results of MOD_<U|S>.<B|H|W|D> the same as on
    hardware
