M68k Inline Assmbly with C Style Operands

["Alex Holland" <alexh at stellarwinds dot com>]

Hi,

 

Using gcc-2.95.2 cross development tools  for a m68k-elf target under Cygwin, I am having problems getting inline assembly with C operands to compile/assemble/link:

 

// Example 1: No C style operands  works fine.

asm("move  0x2700, %sr"); 

 

// Example 2: The % in %sr made the compiler look for another operand.

#define MY_MACRO 0x2700

 

asm("move  %0, %sr;"
    :
    : "i"(MY_MACRO)
);

 

// Example 3: Would not link because sr is undefined.

asm("move  %0, sr;"
    :
    : "i"(MY_MACRO)
);

Any suggestions for making Example 2 or Example 3 work?

 

Thanks,
Alex
