crosscompiling for r5k.

crosscompiling for r5k.

[Richard Hartensveld]

Hi,

I'm having problems crosscompiling a kernel for my challenge s (180mhz
R5000).

I had this problem before but lost the solution during a harddisk
crash.

Is it normal that when you configure for a r5k, gcc uses the
'-mcpu=r8000' option?.
When i compile, i get a kernel, only it won't boot.

i am compiling on i386.

Some of you have come up with a fix the last time, only i haven't got it
anymore, anyone that
could help ?

Richard

Doesn't matter.  GCC 2.7.2 only knew about TFP but not R5k.  I choose to
pass -mcpu=r8000 because for the one optimization where it matters the R8000
was the best match for the R5000.  Things would be different if we'd use
floating point, but we don't.

Did you get trapped by the -N option bug in ld?  Just dump that option from
CFLAGS in arch/mips/Makefile.
