inline assem problem with -fPIC gcc3.3.1

[kscho]

Hi~

When I make shared library with option -fPIC, the result is wrong and
different
that made static library.

first time , I made apps with static library. code works fine.
however when i make apps with shared library , it's not fine. but I must
use shared library.

My library is something about image routine(contain s mmx inline assembly).

This code is inline assem sample

extern const short tab_row[];
extern const short tab_col[];
img_mmx(short* blk)
{
asm volatile(
....
:
:"m"(blk), "m"(*tab_row), "m"(*tab_col)
:"memory"
);
);
 
}
 

This is check result with nm :
------------------------------------------------
with -fPIC

U _GLOBAL_OFFSET_TABLE
....000  T __i686.get_pc_thunk.bx
....000  T __i686.get_pc_thunk.cx
....324  T img_mmx
U tab_row
U tab_col
 

no -fPIC

....324  T img_mmx
U tab_row
U tab_col
 

-------------------------------------------------------

compile with gcc3.3.1

I think this problem is about memory reallocation. How do i solve it?
Anyone have a similar problem with this?

thanks in advance

What was your C language question? In your opinion, what did they create
gnu.gcc.help for?
