[PATCH 0/2] m68k fpu fixes

Posted by KONRAD Frederic 4 years ago

Here are two fixes for the m68k targets:
  - the first one implements a fix about infinity handling when converting
    it from extended format to double or single format.
  - the second fixes the length of the floating points registers for GDB.

Changes:
  * target/m68k/cpu.c: created DEFINE_M68K_CPU_TYPE_CF and dropped
                       DEFINE_M68K_CPU_TYPE_WITH_CLASS (Suggested by Laurent)
  * target/m68k/cpu.c: reworked DEFINE_M68K_CPU_TYPE_* to guess the
                       cpu_initfn from the cpu_model (Suggested by Laurent).

Cheers,
Fred
