Problem with gcc-like inline assembly in cc

Question

Hi,
I am trying to compile the following code for a sparc machine using sun studio 12.
#define MAGIC(n)  asm("sethi %0, %%g0" : :"g"(n));
int main(int argc, char **argv)
        int x=1;
        MAGIC(x);
        return 0;
}I am using the following command:
cc -xO3 -xtarget=ultra2 -m32 -xarch=sparcvis -xregs=no%appl -w test.c -o test
and I get the following error:
cg error (as) : "__gnu_asm_inline_fake_test.c (template for __gnu_asm_inline_temp_func_001)", line 1 : statement syntax
cc: cg failed for test.c
Isn't Sun cc supposed to support gcc-like inline assembly? If so, what is the problem with the code above?
Thanks in advance,
Nick

Hi,
we have the same Problem with the inline assembler. We are using Sunstudio 12 on x86 and tried to get this code compiled (Sunstudio 12 should be gas compatible).
any ideas ?
thanks
