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