The unwinder table consists of a series of four-word entries, the
|

first two of which are a pair of code addresses. While it would be
|
||||
possible to relocate this table using 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.

R_PARISC_BASEREL14F = 0x2f,
|
||||
|
||||
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.

|
||||
R_PARISC_TEXTREL32 = 0x31,
|
||||
R_PARISC_DATAREL32 = 0x39,
|
||||
|
||||
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
|
||||
|
||||
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 ofthe 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
|
||||
popped from the top of the stack prior to popping the
|
||||
amount to be shifted. */
