unsupported relocation type in PPC

[David de Andrés Martínez <ddandres at disca dot upv dot es>]

Hi all,

I am trying to build a .s file where it is implemented one function from
a .c file just for optimization.

When I compiled the .s file I obtained a lot of "unsupported relocation
type".
Looking for the solution, I found that I must include the option
-mregnames for gas to understand that rX were registers.

After that I have solved many of the errors, but I still obtain seven
"unsupported relocation type".
I am enclosing some of the code lines that generate the errors:
....
lwz r5, PBDAT(r4)
....
li r5, TIMER_MAX
....

PBDAT and TIMER_MAX are defined as follows:
#define PBDAT IMR_ULONG( 0x0AC4 )
#define IMR_ULONG( addr ) V_ULONG( CFG_IMMR + addr )
#define IMR_ULONG( addr ) ( addr )
#define V_ULONG( a ) (*(volatile unsigned long *)( a ))
....
#define TIMER_MAX (0xFFFFFFFF)
....

Do you know how to fix the problem?
Any help would be grateful.
