Hello all,
	I would like to know as to how I could access the C variables from
assembly language constructs using gcc. I did go through the info
pages, but I was never able to follow them. (Yes, I did make a honest
effort). I am running gcc 2.7.2 on a sun sparc system (4.1.3). I am
not able to get even the sethi instruction compile.

I have tried the following variants.

asm("sethi %%hi(%0), %%i7", :: "m" (foo.bar));
asm("sethi %%hi(%0), %%i7", :: "n" (foo.bar));
asm("sethi %%hi(%0), %%i7", :: "i" (foo.bar));
asm("sethi %%hi(%0), %%i7", :: "V" (foo.bar));
asm("sethi %%hi(%0), %%i7", :: "o" (foo.bar));
asm("sethi %%hi(%0), %%i7", :: "r" (foo.bar)); // I know this does not
// make any sense, but I did try it any way.
asm("sethi %%hi(%0), %%i7", :: "s" (foo.bar));
asm("sethi %%hi(%0), %%i7", :: "X" (foo.bar));

where foo is a structure and bar an element of that structure. I
request one of the gcc gurus to help me. I am in desperate situation
as I need this information for my course project. Thanks a lot in
advance. 

Wishing you all happy holidays.
Best regards,
