[Qemu-devel] [PATCH v3 0/4] target/m68k: implement 680x0 FPU (part 3)


From: Laurent Vivier
Subject: [Qemu-devel] [PATCH v3 0/4] target/m68k: implement 680x0 FPU (part 3)
Date: Fri, 23 Feb 2018 15:59:55 +0100

Implement fmod, frem, fscale, fgetman and fgetexp.

Instead of using functions of libm (v1 of this series)
and converting between host long double and floatx80 type
the new version (v2) adds new floatx80 functions in softfloat.

All the floatx80 functions are copied from "Previous",
the NeXT Computer Emulator, and written by Andreas Grabher.

v3: Move all new functions to target/m68k/softfloat.c
    Exports needed functions from fpu/softfloat.c

Laurent Vivier (4):
  softfloat: export some functions
  target/m68k: add fmod/frem
  softfloat: use floatx80_infinity in softfloat
  target/m68k: add fscale, fgetman and fgetexp
