Description Aparna Jain 2008-03-04 06:01:53 UTC 
Hi,

I am trying to compile romInit.s in vxWorks. And I am getting too many errors 
of following type

../romInit.s:452: Error: too many positional arguments

The reason is the Macro definition does not take any space around operator

for ex:

li r3, MACRO_DEF

where as MACRO_DEF is
#define MACRO_DEF  (a + b)

#define a 0x1000
#define b 0x2000

To be able to compile successfully the above definition needs to be changed to


#define MACRO_DEF  (a+b)


#define a (0x1000)
#define b (0x2000)

it reduces readability and it is tedious to do for all MACROS lise this

thanks
aparna

Please attach a test case.  Your bug report doesn't make sense.  You say you are
using #define, ie. C preprocessor macros, but complain about a gas macro error
message.

Hi,

Thanks for the reply

Ok, sorry for the confusion.
I did not give complete details.

It normally happens when the defines are in a .macro definition

For ex:

An Asm instruction

 LOAD32  r4,FISRT_BLOCK_END

Where as
     .macro LOAD32 reg,val
        .if ((0xffff8000 <= (\val) ) && ( (\val) <= 0x00007fff))
         li     \reg, \val
        .else
         .if ~(\val) & 0xffff8000
          lis   \reg, HIADJ(\val)
         .else
          lis   \reg, 0x0000
         .endif
         .if (\val) & 0xffff
         addi  \reg, \reg, LO(\val)
         .endif
        .endif
        .endm

And

#define FISRT_BLOCK_END   (LOCAL_MEM_LOCAL_ADRS+EXC_MSG_OFFSET - 4)

Gives too many positional  argumnet error

If I change the definition to  
#define FISRT_BLOCK_END   (LOCAL_MEM_LOCAL_ADRS+EXC_MSG_OFFSET-4)

It is fine

I think there is a similar bug Id 1077, but still in open state

Thanks
aparna

You still haven't attached a test case.  Your pasted code snippets will not
assemble without the definitions for HIADJ and LO.  Incidentally, the LOAD32
macro is broken on 64-bit hosts or when binutils is compiled with a 64-bit bfd.

If you can't post a complete testcase, please try a newer version of binutils. 
I think your problem has already been fixed.

Closing due to lack of response.
