Maybe it's better to switch on fpu emulation in kernel, rather than =
using soft floating points of glibc.

  Subject: [kaffe] compiling with -msoft-float


  Hi,
  Im trying to compile kaffe on powerpc with the CFLAGS -msoft-float

  When it arrives at support.c it gives me that:
  support.c: In function `sysdepCallMethod':
  support.c:1051: Internal compiler error:
  support.c:1051: internal error--insn does not satisfy its constraints:
  (insn 1006 1003 515 (set (reg/v:DF 40 f8)
          (mem:DF (plus:SI (reg:SI 31 r31)
                  (const_int 8 [0x8])) 0)) 441 {*movdf_softfloat32} =
(nil)
      (nil))


  Anybody ever compiled kaffe with software floating point operations?

  the embedded board I have doesnt have a FPU so I have to do it this =
way

  Later
