Either cpp or the assembler is at fault in this problem.
Using gcc on the following code causes the assembler to issue
the error "too many positional arguments"
# Load immediate word, has to be done with 2 instructions
.macro lwi reg,val
lis \reg,[EMAIL PROTECTED]
ori \reg,\reg,[EMAIL PROTECTED]
.endm
#define SOME_ADDR 0x80000000
#define SOME_OFFSET 0x0068
lwi r25,(SOME_ADDR+SOME_OFFSET)
Using the gcc -E option reveals:
lwi 25,(0x80000000 +0x0068)
Hard coding the lwi statement as follows so that cpp does not
touch it fixes the problem:
lwi 25,(0x80000000+0x0068)
This occured with binutils 2.15 and 2.16.1
