Linux/PPC assembly language documentation ?

[Jacques MENU]

Hi folks,

I'm doing work on GNU Prolog that features a ppc_linux.c file, generating code the way shown below.

I'd like to find a description of ''@ha' and '@l' used in instructions like  :
	addis	9,0,.Lcont001 at ha
and
	addi		9,9,.Lcont003 at l

Please answer by email too since I'm not yet a member of this list. Thanks a lot !

Regards,

  Inst_Printf("addis", "9,0,.Lcont%d at ha", w_label);
  Inst_Printf("addi", "9,9,.Lcont%d at l", w_label);
  Inst_Printf("stw", "9,%s", asm_reg_cp);
#else
  Inst_Printf("addis", "%s,0,.Lcont%d at ha", asm_reg_cp, w_label);
  Inst_Printf("addi", "%s,%s,.Lcont%d at l", asm_reg_cp, asm_reg_cp, w_label);
#endif

  Pl_Jump(label);
  Label_Printf(".Lcont%d:", w_label++);

#ifndef MAP_REG_E
  if (use_envir)
    Inst_Printf("lwz", "%s,%d(%s)", asm_reg_e, MAP_OFFSET_E, asm_reg_bank);
#endif
}
