- /* just R_HPPA_32, the amount of relocation data resulting would be */
- /* very large. To reduce that data, the following relocation types */

-
- /* The first, R_HPPA_UNWIND_ENTRY, merely compresses two R_HPPA_32 */
- /* operations into one. It is designed for use in .rel-type */
- /* relocations, where the two 32-bit addends are taken from the unwind */
- /* section itself. */
-
- /* The second, which is designed for use in .rela-type relocations, is */
- /* designed to relocate an entire unwinder table with one relocation */
- /* entry. It has the effect of multiple R_HPPA_UNWIND_ENTRY */
- /* relocations applied to successive unwinder table entries. The */
- /* number of entries to be relocated is given in the r_addend field of */
- /* the relocation entry. The rest of the relocation entry is used in */
- /* a normal way--r_offset is the offset of the first unwind entry in */
- /* the section, while ELF32_R_SYM(r_info) is the code section that all */
- /* the code addresses should be relocated from. */

-
- /* 9.3.11. Relocation types for complex expressions */
-
- /* As described above, new-format SOM fixups support complex */
- /* expressions by spreading the parts of the expression across */
- /* multiple entries. ELF for HPPA will have a similar mechanism, */
- /* although support for it may be optional. There are two main */
- /* reasons for defining it: first, the need to translate complex */
- /* SOM fixup expressions to ELF, and second, to cover combinations */
- /* of expression, field and format not available with other */
- /* relocation types. */
-
- /* ELF expression relocation entries are interpreted as postfix-form */
- /* expressions. They may be evaluated using a push-down stack. */
-
- /* Usually, the addend field of these expression relocation entries is */
- /* unused, with the following exceptions: */
-
- /* R_HPPA_PUSH_CONST: The addend field contains the constant. */
-
- /* R_HPPA_PUSH_PROC: The high-order 10 bits of the addend field */
- /* contain parameter relocation information. The rest of */
- /* the addend field is unused. */
-
- /* R_HPPA_LSHIFT, R_HPPA_ARITH_RSHIFT and R_HPPA_LOGIC_RSHIFT: */
- /* The addend field normally gives the amount to shift. */
- /* However, if that amount is zero, the shift amount is */
