NOTE:
All the "I" forms refer to 29000 instruction formats. The linker is
expected to know how the numeric information is split and/or aligned
within the instruction word(s). R_BYTE works for instructions, too.
If the parameter to a CONSTH instruction is a relocatable type, two
relocation records are written. The first has an r_type of R_IHIHALF
(33 octal) and a normal r_vaddr and r_symndx. The second relocation
record has an r_type of R_IHCONST (34 octal), a normal r_vaddr (which
is redundant), and an r_symndx containing the 32-bit constant offset
to the relocation instead of the actual symbol table index. This
second record is always written, even if the constant offset is zero.
The constant fields of the instruction are set to zero. */
