R_N0SEL Indicates that the following fixup is applied to the first of a three-instruction
sequence to access data, generated by the compilers to enable the importing of
shared library data.
R_N1SEL Uses a (N´) field selector for the next fixup request. This indicates that zero bits
are to be used for the displacement on the instruction. This fixup is used to iden-
tify three-instruction sequences to access data (for importing shared library
data).
R_LINETAB Defines the beginning of a line table. CU is a symbol index of the symbol that
labels the beginning of the line table. SM is the offset relative to the CU symbol.
ES designates the version information for the current line table.
R_LINETAB_ESC
Defines an escape entry to be entered into the line table. ES designates the
escape entry entered in the table. M designates the number of R_STATEMENT
fixups to be interpreted as raw 8-bit table data.
R_LTP_OVERRIDE
Override the following fixup, which is expected to be a R_DATA_ONE_SYMBOL
fixup to copy one data word without relocation when building a shared library.
The absolute byte offset of the symbol relative to the linkage table pointer is
copied. If the linker is building a complete executable, the absolute virtual
address is copied.
R_COMMENT Fixup used to pass comment information from the compiler to the linker. This
fixup has a 5 byte argument that can be skipped and ignored by applications.
R_TP_OVERRIDE Override the next one of these fixups seen: R_DP_RELATIVE, R_DLT_REL, or
R_DATA_ONE_SYMBOL, to use the thread local storage offset when fixing the
instruction. This fixup is also used to catch thread local storage symbol
mismatches.
R_RESERVED Fixups in this range are reserved for internal use by the compilers and linker.
The following table shows the mnemonic fixup request type and length and parameter information for each
range of opcodes. In the parameters column, the symbol D refers to the difference between the opcode and
the beginning of the range described by that table entry; the symbols B1, B2, B3, and B4 refer to the value
of the next one, two, three, or four bytes of the fixup request, respectively.
