["Senti" <senti1 at k dot ro>]

In i386.h machine description file there are 3 lines as follows :

 

fprintf (FILE, "\tleal %sP%d@GOTOFF(%%ebx),%%edx\n", \

                LPREFIX, (LABELNO)); \

fprintf (FILE, "\tcall *_mcount@GOT(%%ebx)\n"); \

 

1.) Can anyone help telling me what @GOTOFF(%%ebx) and @GOT(%%ebx) means ?

2.) Or the "*" in front of _mcount .

I've built the gcc without these and i didn't saw anything going wild .

If someone can translate that to me or tell me where i can find some docs about it i would be grateful.

Thanks , Adrian
