SPARC: Relocation Entries
On the SPARC platform, relocation entries apply to bytes (byte8),
half-words (half16), words (word32), and
extended-words (xword64).
The dispn
family of relocation fields
(disp19, disp22, disp30) are
word-aligned, sign-extended, PC-relative displacements. All encode a value with its least
significant bit in position 0 of the word, and differ only in the number of bits allocated
to the value.
The d2/disp8 and d2/disp14 variants encode 16 and
10-bit displacement values using two non-contiguous bit fields, d2, and
dispn
.
The immn family of relocation fields
(imm5, imm6, imm7,
imm10, imm13, imm22) represent
unsigned integer constants. All encode a value with its least significant bit in position 0
of the word, and differ only in the number of bits allocated to the value.
The simmn
family of relocation fields
(simm10, simm11, simm13,
simm22) represent signed integer constants. All encode a value with its
least significant bit in position 0 of the word, and differ only in the number of bits
allocated to the value.
