GAS is distributed in the hope that it will be useful,
two symbols. This includes the difference of two symbols when
one of them is undefined (this comes up in PIC code generation).
- We don't define DIFF_EXPR_OK because it does the wrong thing if
- the add symbol is undefined and the sub symbol is a symbol in
- the same section as the relocation. We also need some way to
- specialize some code in adjust_reloc_syms. */
+ We allow the difference of two symbols when the subtract symbol is
+ local to the relocation. This is implemented using R_HPPA_COMPLEX.
+
+ This has some limitations. Difference expressions only work between
+ symbols in the same segment/quadrant of a module since the HP dynamic
+ loader relocates the text and data segments independently. Thus, a
+ difference expression can't be used between text and data symbols,
+ or between symbols in different executable modules. */
