[Qemu-devel] [PATCH 0/7] target/m68k: implement 680x0 FPU (part 2)

[Laurent Vivier]

Second part of patches submitted in the v3.

This series adds a subset of single precision and
double precision instructions using
set_floatx80_rounding_precision() to round the result.

For some other instructions, we introduce a new
function, floatx80_round(), to round them manually.

It also adds instructions fsglmul, fsgldiv,
fmovecr and fscc (since v3, use tcg_gen_setcond())

fmovem manages static and dynamic register list,
all the code has been moved to an helper.

Laurent Vivier (7):
  target/m68k: add fscc.
  target/m68k: add fmovecr
  target/m68k: add fsglmul and fsgldiv
  target/m68k: add explicit single and double precision operations
  softfloat: define floatx80_round()
  target/m68k: add explicit single and double precision operations (part
    2)
  target/m68k: add fmovem
