From: Mateja Marjanovic <[email protected]>
Add support for MSA instructions while executing QEMU on a
machine that uses big endian MIPS CPU. Also change the
implementation of helpers for MSA instructions
ST.<B|H|W|D>, LD.<B|H|W|D>, INSERT.<B|H|W> (and D on MIPS64),
COPY_S.<B|H|W> (and D on MIPS64) and COPY_U.<B|H> (and W
on MIPS64). Instead of using a switch in a helper, which is
called many times, put a switch in translate.c file, which
is called only a few times.
v3:
- Unroll loops in ST.<B|H|W|D> and LD.<B|H|W|D>
instructions.
- Eliminate macro that generates the helpers for
the ST.<B|H|W|D> and LD.<B|H|W|D> instructions,
and add four helpers for each (for byte,
halfword, word and doubleword).
- Eliminate the helpers for INSERT.<B|H|W|D>,
COPY_S.<B|H|W|D> and COPY_U.<B|H|W> and add
four (three in case of COPY_U) helpers for
each one.
