These extended instructions allow a 16-bit/20-bit/24-bit immediate to be loaded directly into a general-purpose
register. A symbol also can be used for immediate specification.
Basic instructions after expansion
Expanded into the ld instruction
sld, xld
Expanded into the ld.a instruction
sld.a, xld.a
Expansion formats
(1) sld
%rd,imm16 / xld
Example: xld
%rd,imm16
imm16 ≤ 0x7f
ld %rd,imm16(6:0)
(2) sld.a
%rd,imm20 / sld.a
Example: sld.a
%rd,imm20
imm20 ≤ 0x7f
ld.a %rd,imm20(6:0)
(3) xld.a
%rd,imm24 / xld.a
Example: xld.a
%rd,imm24
imm24 ≤ 0x7f
ld.a %rd,imm24(6:0)
(4) sld
%rd,symbol±imm16 / xld
Example: sld
%rd,symbol±imm16
Unconditional
(symbol ± imm16)(15:7)

%rd,(symbol ± imm16)(6:0)
ld
(5) sld.a
%rd,symbol±imm20 / sld.a
Example: sld.a
