just reserving 8 bytes not initializing it.
probably u compare some garbage. sometimes it equals,
sometimes not.
no?
I write wrong, not if (_vga_x == _vga_y) but if (&_vga_x ==
&_vga_y)
try to do next:
add funtion in asm that returns real addresses to vga_x,y
extern(C) void asmVgas( int** px, int** py)
call it
int *px, *py;
asmVgas( &px, &py);
writefln( "%s=%s,%s=%s",px, &_vga_x,py, &_vga_y);
and see result
I followed your suggest, call asm_fn in d function. it return
address not 0 but is a correct
address same as the var address show in link map file.
when a try define a __shared int xx, the &xx also 0.
after linked all variables address is 0 that in .bss segment.
do you know why occur this?
[global asm_fn]
asm_fn:
mov rax, p2_table
ret
